optimal charging. Refer to page 48 of this manual for correct refrigerant charging
based on your interconnect length. Charge the system with the correct amount of
refrigerant and mark the amount with a ballpoint pen in the space provided on the unit
nameplate.
Note
: When charging through the suction service valve the refrigerant should be
charged in vapor form. NEVER CHARGE IN LIQUID FORM. Refrigerant should always
be charged through a dryer. Charging in liquid form may damage the valve plate
assembly as well as scrub the oil out of the compressor bearings.
Be sure there is not an overcharge of refrigerant. An overcharge might permit liquid
refrigerant to enter the motor compressor and damage the valves, rods, pistons, etc.
Wiring the Condenser
•
Wire the system as per the supplied wiring schematics starting on page 16 of this
manual
OR
on the door of the condenser.
•
The DS fan coil unit is powered through a factory-supplied power cord (for DS models,
WGS is hard connected), but you will need to run 24-volt power wires from the low-
voltage terminal block on the fan coil to the terminal block in the junction box in the
condensing unit labeled Y & C. This can be typical controller wire or 18- gauge
insulated wire. (See images below)
