Vintage Cellars SLK Series Evaporator - Manual (Page 2)

INSTALLATION INSTRUCTIONS
CAUTION
This equipment should be installed only by a qualified technician.
1. Select a location for the evaporator coil. The Ideal location would be directly across from the entrance door.
This will purge the entrance area when the door is opened, However since wine cellars are closed most of the
time this is not critical. . Mount the evaporator coil to the ceiling leaving a distance equal to the height of the
unit, minimum, to the wall to allow for proper airflow. If you have a air handler system refer to the additional
information supplied. Wall mount units require no additional space, except to ensure that air flow is not
restricted. Refer to information supplied with the evaporator for more specific information.
2. Place the condenser at the desired location (must be outside the wine cellar in a well ventilated area or
outside). When installing an outdoor condenser be sure that it is located so snow or leaves will not pile up and
block air flow. This can be accomplished by setting the condenser on concrete blocks Etc.
3. Install a line set sized according to Table 1. Insulate the vapor line the entire length of the run. Be sure to
install a “P” trap in the suction line, several may be required if the condenser is higher than the evaporator.
4. Connect your gauges and Vacuum Pump to the condenser and Evacuate the system.
5. While the system is being evacuated, install the thermostat following the manufactures instructions and run
the thermostat wire to the condenser unit, use the R and Y Terminal on the thermostat subbase, connect to the
yellow and red wires in the condenser unit, if the system is an indoor unit use the R and G terminal on the
control relay. On air handler systems refer to the drawing for that system.
If possible, place the thermostat or sensor on the same wall as the evaporator coil near the evaporator air inlet.
This will cause the thermostat to sense the air returning to the evaporator and should cool the entire room
before the unit shuts off, Preventing compressor short cycling
6. Charge the unit with R22 according to Table 1 (or until bubbles appear in the sight glass. Continue to slowly
add Refrigerant until the bubbles just disappear).
7. After the unit has run about 10 minutes check the sight glass. Under normal operation there should be no
bubbles, If there is, the system is low on Refrigerant, Add Refrigerant to eliminate bubbles.
8.
When the wine room has reached 55 Degrees Check the sight glass again and the gauge readings. Suction
pressure should be in the range of 65 to 78. Liquid pressure should be in the range of 250 to 300. Check the
superheat (8-15°) and if necessary adjust the expansion valve to compensate.
