5. Installing the Condensing Unit Continued
C. Provide a one-inch pitch in suction and liquid line toward the evaporator for every 10
feet of run to prevent any refrigerant that condenses in the suction line from flowing to
the compressor or when the unit is off.
D. Mount system on concrete slab outside above average snow fall heights. Unit can
also be mounted to side of house or within a large indoor crawl space, attic, or me-
chanical room that is at least three (3) times the size of the cellar.
E. Prevent dips, sags, or other low spots that will trap refrigerant oil.
F. Evacuate and leak test indoor unit suction and liquid lines by purging the dry air
charge from the unit by opening the liquid line shut-off valve or removing the liquid
line outlet fitting or plug, whichever is applicable for your unit.
G. Pressurize and leak test system (the condensing unit comes pre charged). A pressure
equal to the low side test pressure marked on the unit nameplate is recommended for
leak testing.
H. Evacuate the system to hold at 500 microns and break the vacuum with refrigerant.
Charge the system with the correct amount of refrigerant and mark the amount, with a
permanent marker in the space provided on the unit nameplate. (See chart on below)

fan coil to Y and C connections in condenser housing (shown in
image to the left).
C. Turn on power to the condensing unit 24 hours prior to system
start-up to allow crankcase heater to warm up compressor.
