SAFETY INFORMATION

Please read carefully to prevent serious accidents or injury.

The Geyser-R Heat Pump Water Heater must be installed in the accordance with Local and

National codes as well as the installation instructions in this manual. Before beginning the installation, carefully read the entire manual and check the local, state, and national codes regarding building, electrical, and plumbing installations, or check with your local authorities for clarification of these codes. Failure to install the Geyser-R in accordance with these codes and the installation manual may result in property damage, bodily injury or death.

Disconnect all power before installing or servicing the Geyser-R.

 There is a discharge fan located on the unit. Extreme caution must be exercised to

ensure that any foreign objects including fingers and hands remain clear of the fan area.

Do not stand, sit or place any objects on or beside the unit (clearances are stated in the

installation manual).

Do not allow children to play on or near the unit.

 Make sure all power is disconnected and shut off before moving the unit.

 Cover should not be removed with power on.

Internal components may be HOT. Please allow sufficient time for the unit to cool completely before touching any internal components.

Ensure that the power receptacle for the Geyser-R is rated for 115 V. and at least 15 A.

 Ensure that the electrical supply has a properly rated fuse or breaker protection rated for at least 15 amps. It is suggested to use a dedicated outlet.

 Always wear eye protection during installation.

 Unit weight is approximately 70lbs. All lifting should be done with the handles located on the side of the Geyser-R. Proper lifting should be used in the moving of the unit.

The Geyser-R must NOT be connected to an electric water heater with heating elements larger than 240/5500 watts.

SYSTEM REQUIREMENTS

The Geyser-R should only be installed in a dry/covered location. The Geyser-R is not designed to be installed outside where it can be exposed to adverse weather condition. The ambient air temperature in the installation area should not drop below 50°F (10°C). The cubic area of the space needs to be 1,000 cubic feet or greater for proper air flow and to avoid excessive cooling of the area. The Geyser-R can be installed in attics garages, or basements provided the above criteria are met for proper installation.

The Geyser-R connects to a typical household outlet, 115V, 15 Amp. While the device requires approx. 12 Amps momentarily upon power-up, the device draws 5-8 Amps during normal operation. It is recommended that a dedicated 15 Amp Circuit be used to power the Geyser-R. The Geyser-R is recommended for installation on electric water tanks of 40gallons (151.4 liters) or greater.

 A drain must be available to accommodate condensate generated during operation of the

Geyser-R. In high humidity environments, the Geyser-R is capable of generating as much as 50

pints (24 liters) per day. The condensate can be routed to a floor drain, sink, the house waste line, or to the outside by way of the drain hose (provided).

 Check with the codes in your area for the proper way to dispose of the condensate. A condensate pump may be required (not included).

 Most electric water tanks utilize two heating elements, one at the top of the tank and one at the bottom. The heating element at the top of the tank is called the quick recovery element. This is designed to heat water at the top of the tank if the temperature of the tank falls below the set point of the thermostat. The lower element provides most of the heating in a typical water heater.

The Geyser-R replaces the lower element in operation and provides the majority of the heating requirements. The upper element is left on at the temperature you set it, and will only engage if there is a need for quick recovery. Therefore in normal operation the Geyser-R will provide all the hot water needed and the top element will not run.

The Geyser-R will remove moisture from the air. It is an efficient dehumidifier and many have found that the unit provides all the necessary dehumidification for the space the Geyser-R is located.

 Moisture may occasionally cause frost to form on the evaporator. When the frost builds up, the

Geyser-R will go into a defrost cycle. This could occur as often as every two hours in a cold

INSTALLATION OF THE GEYSER-R

Note: The following installation instructions cover the installation of the Geyser-R in conjunction with an electric water heater. Alternate water tanks may require an

alternative installation method not covered by this manual. It is recommended that you contact Nyle Systems office (1-800-777-6953) and speak with technical support to see if the Geyser-R can be used in a particular application other than an electric water heater.

Survey the area where the Geyser-R is to be installed. Make sure the area is clear of obstructions, clear of debris, and clean of significant dust and dirt that can get into the unit or clog the filter.

Area should be at least 1,500 sq ft of open space.

Ambient air temperature should be at least 50°F (10°C). Temperatures lower than this will cause the unit to defrost constantly and reduce the efficiency. If the temperature in

the space gets lower than 50°F (10°C), it is recommended that the unit be shut off until a constant temperature above 50°F (10°C) can be maintained.

When choosing the placement of the Geyser-R, make sure the fan is not blocked or close to a wall or other object that would inhibit air flow.

The Geyser-R should be placed on the floor or set on vibration isolation pads. Make sure the unit is higher than the drain and the drain line has an unobstructed path to the drain.

 You can install the unit in an elevated position if desired. Make sure the unit is secure and that the piping is not kinked or restricted in any way. The unit should not be installed higher than the top of the water heater.

 Piping should be kept to a minimum and as short as possible to minimize heat loss. 4 feet is the recommended length.

Check the overall condition of the existing water heater.

Make sure the drain is easily accessible.

Be sure shut off valves are in good condition and are in working order.

 If unit is being installed in an attic it is recommended that both hard and soft foam be placed on the joists to absorb any excess vibration.

 Make sure there is an 115V outlet in close proximity to where the unit is going to be installed.

(15)

15 Version 2.9

 Place the Geyser-R in the final location.

 The Geyser-R should be placed as close as possible to the water heater to minimize heat loss through the piping.

Optional: If desired, at this time add a shut-off valve to each line (this is an alternative

installation, that may reduce the unit efficiency slightly)

 Cut your ¾” PEX to length.

 Slip a ¾” Pex crimp onto hose.

 Push PEX onto the PEX end of the ¾” PEX barb that is connected to the “T” on the assembly at the drain valve of the water heater. Repeat for both inlet and outlet hoses.

(16)

16 Version 2.9

 Slide a measured length of Armaflex onto each of the PEX lines.

 Now repeat the process of connecting, and securing the PEX to the (2) ¾” PEX barb fittings on the water inlet and outlet of the Geyser-R.

 CONNECT AS FOLLOWS:

o The PEX line that starts closest to the tank connects to the BOTTOM RIGHT connection on the Geyser (water into Geyser)

o The PEX line that starts further from the tank connects to the TOP LEFT connection on the Geyser (water out of Geyser)

 Make sure Armaflex covers the hose and fittings to minimize heat loss.

 Once you have the PEX tubing connected to both the unit and the water tank, you may now open the cold water valve on the top of the tank to begin filling the tank (this will also allow you to check the connections for leaks!).

 Leave one faucet open in the house while filling to allow air in the tank and lines to escape.

(17)

17 Version 2.9

Alternate Installation of the Geyser-R

Some tank manufacturers use a molded construction that does not allow for a dip tube to be inserted into the bottom of the tank. In this case we recommend the water be heated by the Geyser-R, pulled from a “Tee” on the cold water supply at the top of the tank. The hot water that exits the Geyser-R is to be returned to the tank through a “Tee” at the drain valve.

Note: The following installation requires the cold water inlet to the water tank to be cut and a tee or connector assembly will need to be soldered in place. Nyle Systems recommends this installation be done by a licensed plumber.

FREQUENTLY ASKED QUESTIONS / TROUBLESHOOTING

The following are a sequence of lights and are used for assuring the proper function of the

Geyser-R and to help diagnose the unit if a problem occurs.

On/off button Green Power is on and unit is in standby. Green service light Solid green Unit is producing hot water.

Amber light is on Solid amber Unit is in the defrost cycle.

Red light is on Solid Red Unit is in over current. Lower element of the water heater is on and heating water. Push the red reset button next to the power switch. The Geyser will now operate normally. (There may be a 5 minute delay in starting). If the situation persists, turn the Geyser off and call for service. Call technical support at Nyle Systems. 1-800-777-6953.

Question Answer

I installed the Geyser and turned power on but nothing is happening

When the tank is refilled with cold water, initially the top element of the tank will come on for Quick

Recovery. After about 15 – 30 minutes, the tank will switch to the bottom element, at which point the Geyser will engage.

I installed the Geyser, the first time it engages, it operated for about 10 – 15 minutes after which it switched off and the red light came on.

Most likely during the install air remained in the system and the pump inside the Geyser is air-bound. Push the red reset button next to the power switch and open the drain valve slightly (there may be a 5 minute delay in starting). This will allow the air to escape together with some water (capture the water), allowing the pump to operate normally.

Power was interrupted while the Geyser was operating. After power was restored, the Geyser is now in standby mode.

(25)

25 Version 2.9

My Geyser is going into Defrost Mode frequently.

The Geyser is located in an area where the ambient temperature is low (below 50°F) and the humidity is high.

I moved the Geyser while it was operating. Now there is a red light and the Geyser won't run.

Moving the Geyser while it is operating can cause a locked rotor condition in the compressor. Push the red reset button next to the power switch. The Geyser will now operate normally. (There may be a 5 minute delay in starting)

How do I adjust the

temperature of the water in my water tank.

Turn-off power to the water heater. Remove the water heaters lower cover. Adjust the temperature with the thermostat on the tank. Replace cover and turn power back on.

The red light came on and the Geyser switched off
