35 V10.19
4. Liquid line refrigeration piping in accordance with Line Sizing Chart in Owner’s
Manual.
5. Factory installed liquid line solenoid valve (normally closed). 6000-8000Scm have
two
solenoid valves, 5S and 5P. (Dual Power/Valve Control configurations only).
6. Factory installed thermostatic expansion valve. 6000-8000Scm have two
expansion valves,
6S and 6P.
7. Factory installed ¼” evaporator suction access valve. 6000-8000Scm have two
access
valves, 7S and 7P.
8. Insulated suction line refrigeration piping (refer to Line Sizing Chart in Owner’s
Manual).
9. Suction connection location.
10. Condensing unit ¼” liquid access valve. The position of the access valve varies by
model, trace the liquid line back from the connection through the receiver to the
condenser
coil bottom outlet to locate the valve.
11. Condensing unit ¼” suction access valve located off a tee on the compressor shell
process tube.
12. Field provided dual evaporator liquid line tee. Required on 6000-8000Scm only.
13. Field provided dual evaporator suction line tee. Required on 6000-8000Scm only.
Line Sizing Chart
Refer to the Line Sizing Chart below for selecting the appropriate tubing size for the length
of the piping run. Note that the recommended line size may not match the connection
ports on the Condensing unit and the Evaporator. Refrigeration grade fittings must be
supplied by the installing technician to make the necessary transitions. Transitions
should be made as close to the unit as possible . Suction line routing must be
designed to ensure oil return to the Condensing unit and prevent refrigerant migration in
the off cycle. To route the piping out of the evaporator to connect to the line set, it is
acceptable to use ¼” tubing on the liquid line and 3/8” on the suction line. Transition as
near as possible to match the line set size once the lines leave the evaporator. On the
dual evaporator models 6000Scm and 8000Scm, the lines may be reduced at the liquid
tee and suction tee. Locate these tees as close as possible to the dual evaporators.
