C. Provide a half-inch downward slope in suction and liquid line toward the
condenser for every 10 feet of line-set to prevent an oil return issue from
occurring. This will allow oil in the system to return to the compressor
when the system is off to ensure the system remains lubricated.
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
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)
I. See the full Wine Guardian Operations and installation manual for

For Installations using a line-set distance that are Less Than or Equal To 25' add the
required amount of refrigerant shown in the table above.
For Installations using a line-set distance that are Greater Than 25' add the required
amount of refrigerant shown in the table above THEN add additional refrigerant based on
the rules below:
Models SS018, CS025, DS025, CS050, DS050, WGS25, WGC60, WGS40, and WGS75
Add an additional 0.50 oz/ft (0.465 kg/meter) for every foot exceeding 25'
Models DS088, DS200, WGS100, and WGS175
Add an additional 1 oz/ft (0.93 kg/meter) for every foot exceeding 25'
5. 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.
