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 perim-
eter of the condensing unit for proper airflow across
the unit and for service access.

. Includes charts on sys-
tem Pressures, Superheat, and Sub-cooling.
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 re-
moving the liquid line outlet fitting or plug, whichever is applicable for your
unit.
System Charging
Note: Each SS & WGS Model condensing unit is shipped with 16oz/.453kg of
refrigerant charge already, to be taken into account for below total amounts
based on 25’/7.62 meters interconnect length.
For ¼” OD Liquid line systems: SS018/WGS25:
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)
**For each 1 foot, or 1 meter more or less than 25 feet / 7.62 meters piping,
adjust total system refrigerant R134A charge from above baseline by .50
oz / .0465 kg”
