Application Guidelines

3.1 Operation range

Use this condensing unit within the following operation ranges.
Item
Refrigerant
Evaporation temperature
Low pressure (LP)
Suction gas temperature(Ts)
Discharge temperature(Td)
Ambient temperature
Power supply voltage
Voltage unbalance rate
Note:
1. Install sufficient insulation on liquid feed piping and suction gas piping. (Refer to the insulation (*) thickness in the following table.)
Type
Pipe section
For cooling
For freezing
Note:
Where the thermal conductivity of insulator is 0.035W/m-K, if the liquid feed pipe and the suction gas pipe touch each other, it could
cause a superheat as a result of heat transfer between these pipes. Separate these pipes effectively.
2. Do not use the unit in a corrosive atmosphere.
3. Arrange at site such that the degree of superheat of suction gas will fall within a range of 5 deg to 40 deg.
