8. Turn Unit On
A. Turn the ON/OFF switch to the “ON” position. Green LED
lit when unit is on . The Remote User Interface is preset
to a room temperature of 55°F (13°C).
B. Press the “Up” arrow once. The display will show the exist-
ing temperature setpoint. Press the “up or down” arrow
buttons to adjust the temperature to the desired setpoint.
C. The system will turn on after a 5-minute time delay and the
cold air section will start to deliver cold air. Contact Air Innovations if the system fails to turn on.
7. Wiring the Unit for Power
A. Connect line power to the contactor inside the condens-
ing unit as shown.
B. Run 24 volt low voltage signal wires from Y and C termi-
nals on 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.
*See page 21 in owners manual for full wiring schematic.
Inside of condensing unit also contains schematic.
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 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 refrig-
erant. Charge the system with the correct amount of refrigerant and mark the
amount, with a permanent marker in the space provided on the unit name-
plate. (See chart on below)
I. See the full Wine Guardian Operations and installation manual for comprehen-
sive charging procedure.
