3. Application Range
3.1 Operation range
Note:
1. Install sufficient insulation on liquid feed piping and suction gas piping. (Refer to the insulation (*) thickness in the following table.)
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.
Use this condensing unit within the following operation ranges.
