7. Connect power to the Evaporator and Condensing unit, and activate the system.
IMPORTANT: If the system does not power up after the start up delay (factory
preset is 3 minutes; recommended to be changed to 30 minutes after installation
per instructions below), verify field wiring according to the appropriate wiring
diagram. If correct, disconnect power from the system and contact Cellarpro at
707.794.8000
Measure pressures and temperatures to verify the system is within normal operating
limits as indicated on the Split System Data Sheet. A loose copy of the Data Sheet is
provided with the unit, and an additional copy is included at the end of this manual.
The condensing pressure must be above 105 PSIG when taking these measurements.
In a low ambient environment, it may be necessary to temporarily block off the
condenser air intake to force the condensing pressure higher. Do not run the system
if the suction superheat at the condensing unit is below 20°F.
8. It may be necessary to slightly adjust the charge amount after weighing in the
recommended initial charge. 1) Not enough refrigerant: If the Evaporator is not
providing enough cooling, the system may be undercharged. If liquid subcooling is
below 10°F and the suction superheat is well above the minimum of 20°F, slowly add
vapor refrigerant though the suction service valve until the subcooling is within
specifications. 2) Too much refrigerant: If the suction superheat is below 20°F, remove
refrigerant until the superheat is above this minimum limit.
9. (Optional) It should not be necessary to manually adjust the thermostatic expansion
valve superheat from the factory default setting. However if desired, the superheat
may be adjusted as follows: 1) Remove the cork tape insulation from the expansion
valve body to locate the cap on the superheat stem, and unscrew the cap using a 5/32
in. Allen wrench. 2) Using a 5/32 in. Allen wrench, locate the setting spindle inside the
superheat stem and make superheat adjustments ¼ turn at a time (¼ turn≈1°F).
Turning clockwise increases superheat. Turning counter-clockwise decreases
superheat. The target superheat at the evaporator is 10°F +/- 2°F. 3) Reinstall the cap
and cork tape insulation.
10. Confirm that the compressor, condenser fan, and evaporator fan(s) are energized.
Allow the system to balance for 30 minutes, then record all readings on the Data Sheet
and submit to CellarPro for warranty activation review.
11. Observe that the condensing unit turns on when the “snowflake” icon on the
temperature display is lit solid (not blinking), and turns off when the “snowflake” icon
turns off. It may be necessary to temporarily raise the set point to force the unit to cycle
off. If the condensing unit does not cycle on/off in conjunction with the “snowflake”
icon, please contact the factory for assistance.
12. Once the system is confirmed to be running properly, enter the following programming
change so that the startup delay increases from 3 to 30 minutes:
a. On the control panel, press and hold the "SET" and "DOWN ARROW" buttons
AT THE SAME TIME for 3 seconds (the display will briefly flash).
b. Release when the display starts blinking.
