4. Raise the Minimum Set Point of the cooling unit.
5. Check to make sure the cellar has airtight seals, including the door(s), light
fixtures, and all walls, ceiling and floor.
The HA2 Alarm has been triggered
The cooling unit is designed to measure the temperature of the condenser coils
and, if the temperature exceeds 60°C for more than 2 hours, the HA2 alarm will
display on the control panel.
If this alarm happens when you first receive and start operating your CellarPro
cooling unit, check for appropriate installation and ventilation (Chapter II).
Also, make sure that there aren’t any obstructions to the intake and/or exhaust
vents. If your wine cabinet has a grill, remove the grill and/or any other
obstructions above (top vent) or behind (back vent) the cellar.
If the alarm happens in conjunction with hot ambient conditions, we
recommend doing the following:
1. Raise the Minimum Set Point to 15.6°C until temperatures cool down
2. Increase the Fon setting
If the cooling unit has been operating for several months without any problems
and the alarm occurs, check the condenser filter and clean or replace if necessary.
The LA2 Alarm has been triggered
As noted above, the cooling unit is designed to measure the temperature of
the condenser coils and, if the temperature drops below a certain point, the LA2
alarm will display on the control panel. To reduce the alarm temperature setting,
do the following:
1. Depress the “Set” and “Down” button for three seconds until the display
reads “HY”
2. Depress the “Set” and “Down” button (again) for seven seconds until “PR2”
flashes on the display
3. Using the “Down” button, scroll until the display reads “AL2”
4. Depress the “Set” button and lower the alarm temperature setting to your
desired temperature
