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.
6. Connecting Electrical Wires
Connect all electrical components using the wiring diagrams in accordance with
all state and local codes.
