DOMESTIC PREMISES
OUTSIDE AIR
The EVAPORATOR collects heat from the outside ambient air, pre-heated by the sun. With Ideal, heat pumps high volumes of outside air are drawn into the unit by the fan and expelled through the evaporator fins. The evaporator has liquid refrigerant passing through it, which is at a
considerably lower temperature than the ambient air, therefore the air gives up its heat to the refrigerant, which then vaporizes. This pre-heated vapour now travels to-
The COMPRESSOR where it is compressed and upgraded to a much higher temperature. The hot vapour now
enters-The EXPANSION DEVICE and from there, now at low pressure, it is returned to the evaporator and the cycle starts again.
The CONDENSER where it is surrounded by water from the heating system. The heat is given up to the cooler water and the now cooler refrigerant returns to its former liquid state but still under high pressure from the compressor. This pressure is released by passing the liquid through
-Coefficient of Performance
The efficiency of a Heat Pump is usually called its 'Coefficient of Performance' - (C.O.P.) which is simply a ratio of heat output to energy input, both being expressed in kW. Thus a Heat Pump absorbing 1 kW of electricity, collecting 4 kW of energy from the air, and delivering 5 kW of heat to the pool water is said to have a C.O.P. of 5:1. Naturally this ratio will vary according to the temperature of the water and the ambient air.

IntRoDUCtIon
This installation manual is accompanied by a user guide (see reverse of this book), a commissioning record sheet and a warranty registration card, all of which should be left with the householder. The user guide explains how the system works, how it is controlled and what to do in the event of a problem. The commissioning record sheet must be completed as its production will be required in the event of a warranty claim.
HeAtIng WItH A HeAt PUMP
The Ideal heat pump is designed to operate up to 65oC water temperature for the domestic hot water delivery, and negates the need for direct electrical heating in the form of an electrical emersion heater. The unit also provides space heating temperatures variable from 35oC to 55oC.
Heat pumps for domestic heating are a fully proven technology which will give many years of trouble-free service. Ideal Heat Pumps which are MCS approved have been specifically designed for optimum operation in the UK’s climate.
However, unlike an oil or gas boiler which may be oversized for the heating demand of the property and therefore regularly cycles on and off, a heat pump is closely matched to the heat demand and is designed to run for long periods without switching on/off. The following steps must therefore always be taken to ensure a successful installation. Major problems can occur if they are not taken and failure to comply will invalidate the warranty.
a. SAP or equivalent heat loss calculations must be established with the results recorded on the commissioning sheet.
b. The heat pump must be correctly sized in relation to the calculated heat losses.
c. The space heating system must be capable of satisfying the heat demand at the water flow temperature set for the heat pump. This is particularly important where retro-fitting a heat pump to a radiator system designed originally for a Delta T of 60oC, as the heat pump will run at a Delta T of 30oC. In this situation, you will normally need to fit larger radiators.
d. The electrical supply must be adequate to meet the start current demand.
e. The heat pump and the associated heating system must be commissioned in accordance with the procedures laid down in this manual.
A heat pump may be fitted on a stand-alone basis (monovalent system) to satisfy the full heating and hot water demand of the property or in parallel with an existing boiler (bivalent system). In the case of a bivalent installation the heat pump is sized to provide a variable proportion of the annual heating requirement (say 85%) with the existing boiler integrated to deliver the balance on the coldest days. In bivalent systems, the heat pump is sometimes only linked to the space heating system which eliminates the requirement to fit a new DHW cylinder.
Standard designs for several different configurations, including plumbing and electrical circuits, are included in this manual.

SAFety PReCAUtIonS
a. The unit must be securely installed on a structure that can sustain its weight. If mounted on an unstable structure, it may fall causing injury or damage.
b. If the heat pump is installed in an enclosed area, sufficient ventilation must be provided so as not to impede the air flow through the unit and to prevent the concentration of refrigerant gas in the room building up in the event of a leak. (See diagram - page 6)
c. All electrical work must be performed by a qualified technician and comply with the latest I.E.E (17th) Regulations. The machine should be installed in accordance with EMC 2004/108/EC.
d. Electricity to the unit must be supplied through dedicated power lines and the correct voltage and circuit breakers must be used. Power lines with insufficient capacity or incorrect electrical work may result in electric shock or fire. The electrical ratings of Ideal heat pumps are included in the datasheet on page 16 of this manual.
e. Any external heating device fitted to the plumbing circuit of the heat pump must have its own thermostatic control safety cut out.
f. Immersion heater elements in any hot water tank must have a built in thermostat.

LoCAtIon
The heat pump is suitable for outside installation.
a. Select a location where any potential noise disturbance is minimised.
b. Provide a firm level base capable of supporting the weight of the machine. Fixing holes are provided for bolting the machine down to the base.
c. If wall mounting, ensure that the wall and framework are capable of supporting the machine and use anti-vibration mounts to prevent noise transmission. The weights of the heat pumps are included on the data sheet on page 16 of this manual.
d. If installing in a location exposed to strong wind, do not face the air outlet of the unit against the direction of the wind as wind entering the unit may impede the normal airflow and result in a malfunction.
e. Allow for the minimum clearances around the machine, as shown below, required for unobstructed air flow and access to service panels. A clearance of 1 metre above the unit is recommended for servicing access through the top panel. f. Consider protection from extreme weather conditions with a
cover or enclosure if the machine is installed externally g. Consider fitting a protective guard where the machine could
be exposed to vandalism or other damage.
h. If installed in a plant room or other building, ensure that the air outlet is positioned directly adjacent to the outside wall with inlet and discharge grilles or apertures of minimum free areas as detailed below.

PLUMBIng - PIPeWoRK
a. Ideal heat pumps have water flow and return connections as follows:
· The airtherm 4.5 and 9 models have ¾” BSP parallel, male threads
· The airtherm 12 has 1” BSP, parallel, male threads
b. Couplings suitable for disconnection should be installed with isolating valves on the flow and return of the heat pump to ease installation and maintenance. During the initial installation, these should be the last connections made so as to avoid any stresses on the unit connections.
c. A drain valve or plug should be fitted to the lower pipe to facilitate drain down for servicing.
d. The condensate drain at the base of the unit collects the condensation from the evaporator fins. This should be run away to waste from the ¾” PVC pipe on the side of the heat pump. The routing of the drain must be made to allow a minimum fall of 1 in 20 away from the unit, throughout its length.
e. Do not allow pipe work to run in front of service panels.
f. All pipe work must be adequately supported with allowance for expansion/contraction and should be insulated to avoid unnecessary heat loss.
a. The Ideal air source heat pump is normally designed to operate with a buffer tank which prevents short cycling during normal operation and provides a thermal store to aid defrost of the heat pump. The size of the buffer tank needed varies with the size of the ASHP unit as shown below.
Refer to Page 31-33 for addition information
b. Where the ASHP is required to supply domestic hot water, a special DHW cylinder (Ideal cylinder) should be purchased with each air to water heat pump. These cylinders have a larger primary coil compared to standard cylinders and are supplied with a special tank thermostat. An immersion heater is fitted for back-up DHW heating and must contain a built in thermostat.
c. Where indirect pressurised cylinders are fitted, they should be installed in compliance with the relevant Water Regulations and Building Regulations.

a. A separately fused single phase supply is required. With all power switched off, remove the electrics access panel to gain access to the terminals in the electric box. The supply cable, entering the unit through knock outs in the panel, can then be fed through to connect into the live/neutral/earth terminals.
b. An MCB type C or D or correctly rated fuse must be used. (Refer to data sheet on page 17 of this manual).
c. A local isolator should be fitted within 2 feet of the unit to comply with I.E.E. regulations. Power to the unit is indicated by the red indicator light on the console (mains lamp).
d. A separate fused spur is normally used to supply the central heating programmer and controls.
e. There are 10 connections to be made between the Ideal heat pump and the control wiring centre. A multi core cable with sufficient capacity will need to be provided and installed. In most cases a 12 core 0.5mm control cable is used. f. The unit may be live even when the mains lamp is off
eLeCtRICAL
eLeCtRICAL ConneCtIonS
a. The electrical connections diagrams are on pages 9 and 10 of this manual.
b. The wiring junction box is located behind the access panel below the unit’s control panel
c. For the heat pump to operate, you must have a live signal into terminal 9 (space heating) and terminal 1 (DHW).
InteRnAL WIRIng
a. Internal wiring diagrams are on pages 11 and 12 of this manual.
b. External wiring will depend on the heating system design and is found on pages 22 & 24 of this manual.
due to live feeds from the external control system. The ‘programmer live’ light on the control panel confirms the presence of a supply. (See diagram page 13).
g. The heat pump can operate in one of two modes, either set as supplied, with the unit biased to hot water, or with no bias for hot water or heating.
h. Ideal Boilers would always recommend a system with the heating biased to hot water. However if room heating and hot water heating are required at the same time, the link between terminals 11 and 12 should then be fitted. There is then no bias between room heating and hot water heating.
i. Where the link is fitted the unit will deliver 65ºC flow temperature during periods of DHW demand and this must be considered at system design with consideration to this temperature feeding radiators or under floor heating at these times.
ii. The link cannot be fitted when the heat pump is plumbed in to a ‘W Plan’ system.

Ideal airtherm - Air Source Heat Pump -
Frost protection of the heating circuit is essential. We recommend the use of a combined inhibitor/anti-freeze, either Fernox Alphi 11 or Sentinel X500. The manufacturers’ recommendations on concentration should be followed.
A minimum concentration of 15% to 20% is needed to avoid any risk of corrosion. A 30% concentration gives frost protection down to -15oC, the minimum operating temperature for the ASHP.
When an inhibitor/anti-freeze is used, the water flow and pressure drop need to be increased to the levels shown below.
FRoSt PRoteCtIon
Correct water flow is essential for reliable operation of the heat pump. Using the information in the table above and total system pressure drop the selection of an appropriate water circulation pump can be made. Consult water circulation pump manufactures data sheets for accurate water pump performance.
When the correct water pump has been selected a Delta ‘T’ of 3oC to 5oC between water in-let to outlet temperature indicates correct flow rate.
Where frost protection is provided by the thermostats that control the unit, the water flow and pressure drop should be set to the values shown in the data sheet on page 17 of this manual.

The control panel is located on the right side of the unit under the upper removable steel panel.
1. To access, carefully remove the plastic screw covers and the screws and washers beneath. Place these to one side, ready for re-assembly.
2. Slide the controls cover from the upper location slots and place to one side.
3. Re-assembly is in reverse order, taking care to use the washers correctly to enable the screw caps to be replaced.

All units have integral safety devices to protect the heat pump from integral and external faults and indicator lamps showing operating mode. An adjustable digital thermostat controls space heating and return water temperature. Also a three minute cycle time delay which protects the compressor is incorporated.
CoMMISSIonIng
a. Ensure that all water circuits are clean, purged, leak tested, fully de-aerated and correctly balanced.
b. Add inhibitor/anti-freeze in the correct concentration to ensure frost protection. This is essential, unless frost protection is ensured by thermostats.
c. The control panel for the air source heat pump is located under a secure cover on the right hand side of the machine.
d. Check that all wire connections are correctly made and tight
e. Switch on power at the distribution board and check that there is mains power to the unit.
f. Check that the control system is switched on and that the red ‘programmer live’ lamp is lit.
The space heating temperature controller is used to adjust the return water temperature from the space heating system. For maximum economy, this should be set to the lowest acceptable level.
The setting is adjusted by first pressing and then releasing button P followed by pressing the up or down arrow buttons to display the required temperature. Button P should be pressed again to confirm your settings.
After 5 seconds the display will revert to the actual water temperature.
The amber fault lamp indicates a possible problem in the system. This may be cleared by the manual reset of the high pressure switch (red recessed button). If the fault proves difficult to clear, check that all plumbing and electrical connections are made in accordance with this manual and that the system characteristics required in the data sheet on page 16 of this manual (water flow rates etc) have been achieved. The green defrost lamp is illuminated when the heat pump is defrosting.
g. DHW system tests
i. Set the programmer to DHW and set the cylinder stat to the required temperature
ii. Switch the heat pump on. When first turned on, the machine will go into defrost with the compressor running, the fan off and the green light on. This defrost cycle will run for about 4 minutes.
iii. Check that the system valves operate correctly iv. Check for an increase of 2-3oC in the return water
temperature displayed on the unit control panel. This will confirm that the system is working.
h. Central heating system tests
i. Set the programmer to central heating.
ii. Turn the room thermostat up to 30oC, at which point the water circulating pump should start followed by the compressor and fan. Note; there may be a time delay of 6 mins before the compressor starts - this is normal. iii. Check that the system valves operate correctly iv. Check for an increase in the return water temperature
and for an increase in the radiator temperatures. The initial heat-up of an under floor system will take many hours.
v. Once the system is running correctly, turn any
thermostatic radiator valves to the required settings and set the room thermostat to 21/22oC.
i. Check that the chosen electricity tariff provides the optimum economy in relation to the occupant’s lifestyle and heating demand. When replacing electric storage radiators, note that the Economy 7 or equivalent tariff may not be appropriate for the economic operation of an air source heat pump.
j. Check that the time clock is set to suit the occupant. Where a controller is fitted which features multiple time/temperature periods, set these individually to suit the occupant.
k. Ensure that all service panels are securely fitted with the tamper proof screws.
l. A fault finding chart is provided on page 15 of this manual.
m. Complete the commissioning sheet on page 34 of this manual.
HAnDIng oVeR
a. Hand the user instructions to the householder and explain his/her responsibilities under the relevant regulations.
b. Explain the start and shut down procedures.
c. The operation of the heat pump and the use and adjustment of all system controls should be fully explained to the householder, to ensure the greatest economy consistent with heating and hot water household requirements.
d. Advise the user of the precautions necessary to prevent damage to the system and heat pump.
e. Explain the function of pump fault light.
f. Loss of system water pressure - Explain that the system pressure gauge indicates the central heating system
pressure and that if the normal COLD pressure of the system is seen to decrease over a period of time then a water leak is indicated. Explain the re-pressurising procedure and if unable to re-pressurise or if the pressure continues to drop a registered local heating installer should be consulted.

Mounting Location
For optimisation the sensor must be positioned on the coldest wall of the house (normally wall facing north). The sensor must never be exposed to the morning sun.
Mounting Height
Preferably in middle of dwelling to be heated, but at least 2.5m above the ground. Must not be fitted above windows, doors, air extracts or other heat sources, below balconies or in the eaves of the roof.
The sensor must not be painted over.

MOUNTING POSITIONS
KEEP AREA AROUND SENSOR CLEAR OF INSULA TION STRAP ON TEMPERATURE SENSOR AT9649There are a number of main points that affect the buffer sizing requirements as follows:
1. A constant water flow of +/- 10% of design must be maintained through the heat pump. This can be achieved using good system design. Where TRV’s or underfloor heating are used special care must be taken to ensure the flow is maintained regardless of system turn down.
2. The assumptions using combination cylinders in table1 assume that the buffer vessel is plumbed in series with the radiator circuitry simply adding water volume to assist flow rates.
3. Table 2 shows the temperature drop in the water volume in the buffer and the heat distribution circuit as a result of providing energy for the heat pump to perform defrost functions when necessary.
