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 mechanical 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 re-
moving 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 name-
plate 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)

hensive charging procedure, pressures, superheat, sub-cooling charts.

System Charging
Note: Each SS, DS & WGS Model condensing unit is shipped with
16oz/.453kg of refrigerant charge already.
For systems: SS018/WGS25, DS025/WGS40, DS050/WGS75:
For a typical baseline interconnect line set of 25' / 7.62 meters, here are the
recommended factory total system refrigerant charges by model:
SS018=51oz / 1.45kg (includes added charge required if an XLA system)
WGS25=1.53kg (includes added charge required if an XLA system)
DS025= 63oz / 1.78kg (includes added charge required if an XLA system)
WGS40=1.75kg (includes added charge required if an XLA system)

Installing the Condensing Unit
A. Wine Guardian condensing unit must be mounted
horizontally on its base as shown and be level to +/- ¼"
end to end and 1/8" side to side.
B. A minimum of 12 inches is required around the
perimeter of the condensing unit for proper airflow
across the unit and for service access.
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.
