1) Place the condensing units WM-250~650SCUR in a properly ventilated
location. Otherwise, heat exhausted by the condensing unit will build up and
the cooling system will not operate properly.
2) Condensing unit shall be elevated to avoid possible flooding and shaded from
direct sun. It shall not be exposed to temperatures higher than 110 °F or
lower than 50 °F.
3) Leave minimum 5 ft clearance for the air exhaust side and leave minimum 1
foot clearance for the air intake side.
5. Refrigeration Piping and Leak Testing
NOTE
The line connector sizes of liquid filter and indicator, the valve
connector sizes of condensing unit or the line connector sizes of
evaporator unit may not be the same as the listed refrigeration line
sizes.
If the condensing unit is installed above the evaporator unit, use
the suction line one size smaller.
Expansion and solenoid valves have been installed on the liquid
line in the evaporator unit.
The line sizes and refrigerant charges are listed as follows.

1) The piping starts from à condensing unit’s receiver discharge valve à liquid
filter à liquid indicator à liquid line à to evaporator unit’s liquid line
connection (assembled with solenoid valve and expansion valve) à suction
line connection à insulated suction line à to condensing unit’s suction valve.
2) If the line set exceeds 75 ft long, use both inverted U trap and suction
accumulator to prevent liquid from flooding back to the compressor.
3) If the condensing unit is located below the evaporator unit, use inverted U
trap to prevent liquid from flooding back to the compressor. If the elevation
difference is more than 10 ft, use both inverted U trap and suction
accumulator.
4) If the condensing unit is located more than 10 ft above the evaporator unit,
use U trap to aid oil returning to the compressor.
5) Complete pipe brazing, check solenoid valve and expansion valve restrictions
and perform leak testing.
6) Hook up the drain line and check if water drains.
