1 DVI compressor Digital Vapor Injection)
DVI compressor coupled with vapor injection controls the capacity 10 to 100% of its ca-pacity.
It enhances cooling and heating performance and COP with using vapor injection.
2 FVI compressor
(Fixed Vapor Injection) FVI compressor coupled with vapor injection is fixed compressor. It enhances cooling, heating performance and COP with using vapor injection.
3 PWM valve |t is used for variation of digital compressor’s capacity. When the valve is open, the DVI compressor keeps the unloading state, otherwise loading state.
4 Discharge temp. sensor It measures the temperature of compressor outlet. The main function of it is to protect compressor from overheating.
5 Oil separator It separates oil and refrigerant discharged from the compressor and returns the oil into compressor again.
6 High pressure switch It protects the system from abnormal high pressure. (Open : 4.1Mpa, Close : 3.5 Mpa) 7 Hot gas bypass valve When the suction pressure becomes abnormal low pressure, it opens.
During the oil balance operation, it makes high pressure for the shell of compressor 8 High pressure sensor The main function of it controls the capacity of compressor in pursuit of target of high
pressure in heating operation by measuring the value of the system.
9 4way valve It enables to change operating mode into cooling and heating mode.
10 Ambient air temp. sensor It measures the temperature of ambient.
11 Cond_out temp. sensor It has application to know subcooling and the complete point of defrost.
12 Main EEV 1, 2 It controls the amount of refrigerant entering outdoor’s heat exchanger in heating operation.
13 Liquid bypass valve When the compressor is overheating, it opens to make discharge temperature low.
14 EVI EEV It enables to secure sufficient subcooling and control the amount of vapor entering into vapor port of compressor.
15 Turbo intercooler Through turbo intercooler, heat is exchanged each other between saturated liquid refrigerant and a little expanded refrigerant.
16 EVI_in temp. sensor
These temperature sensors enable to control EVI EEV’s step to secure superheat.
17 EVI_out temp. sensor
18 Liquid tube temp. sensor It is used to know subcooling.
(Subcooling = The saturated temp. of high pressure - Liquid tube temp.) 19 EVI bypass valve This valve closes during application of vapor injection.
20 Suction temp. sensor This is applied to know superheat in heating mode with the low pressure sensor.
21 Accumulator Ambient air temperature sensor (Tair)
22 Oil valve When oil balance operation happens, this valve opens.
23 Low pressure sensor The main function of it is to control the capacity of compressor in pursuit of target of low pressure in cooling operation by measuring the low pressure.
24 Sump(Base) temp. sensor With checking sump temperature of compressor, it prevents the compressor from liquid back and overheating.
25 Oil temp. sensor While the oil balance is operating, it make a self-diagnosis of the oil valve.
26 Main cooling valve Through this valve, the high pressure gas of refrigerant is discharged into indoor unit which needs heating operation in main cooling operation.

2-3. Installing duct for horizontal exhaust discharge
It is necessary to install an air-discharge duct (field supply) to direct exhaust from the fan horizontally if it is difficult
to provide a minimum space of 2m between the air-discharge duct outlet and a nearby obstacle.
Installation
excessive wind and snow should be taken to ensure the unit's correct operation. Snow-proof duct (field supply)
should be fitted to the unit and direct exposure to the wind should be avoided as much as possible. When the unit is expected to operate in cooling mode in condition under 10ºC, in snowy areas, in environments subject to strong winds or rain, install air inlet and outlet ducting as shown in the below example
The frame/foundation should be higher than expected snowfall.
The foundation must be solid and the unit must be secured with anchor bolts.
Be sure to install unit in a place strong enough to withstand its weight.
When installing on a roof subject to strong wind, countermeasures must be taken to prevent the unit form being overturned.
Any lack of strength may cause unit to fall down, resulting in a personal injury.
For more detail information about installation, refer to installation manual.

Cautions Correct piping work Wrong piping work
The refrigerant piping should be the same level or lower than connecting position of piping to outdoor units.
Piping work should be run with side direction for better uniform distribution of refrigerant and oil like next diagram.
Outdoor joint kits should be installed in a horizontal direction, even it is a low pressure pipe.
When the piping length between outdoor and branch joints is 2m or more, a vertical trap has to be installed like right diagram.
Less than 1m 2m or more
2m or more 200~300mm
