The Cooling Unit Won’t Turn On.
The cooling system is programmed with a 3-Minute Delay at Startup to protect its
internal components.
The HA2 Alarm has been triggered
HA2 alarms should be addressed as soon as possible, otherwise permanent damage
may occur to the compressor.
CellarPro cooling units are designed to trigger an HA2 alarm when the temperature at
the condenser coils gets too hot. HA2 alarms generally occur when:
-
The condenser fan (at the rear of the cooling unit) isn't turning, and/or
-
The filter and/or condenser coils must be clean and free of blockages
-
Our filters are custom-made for our cooling unit, and should never be replaced
with filters that are not purchased from CellarPro
-
Airflow at the rear of the cooling unit is restricted or too small for the hot air
exhaust to dissipate, and/or
-
Ducting at the rear of the cooling unit is incorrectly installed or too restrictive,
and/or
-
The thermal load of the wine cellar or cabinet exceeds the capacity of the
cooling unit, and therefore the cooling unit never turns off
-
The maximum intake temperature should not exceed 95F (90F for 1800XTSx
units)
When your cooling unit flashes an HA2 alarm, please do the following:
1.
Check to see if the hot-side fan is operating when the fan icon is lit on the
digital display. If the condenser fan is not operating, turn the unit "Off'", then
check to see if the fan blades will spin freely
Please note: there are multiple fans inside each cooling unit. The HA2 alarm
is related to the fan on the hot side (ie at the rear) of the cooling unit. Even if
the fan inside the cellar is operating, you must check to see if the fan(s) on
the hot side is operating.
2.
Confirm proper installation
o
The hot side of the cooling unit must be completely separated from the
cellar – it can’t pull air from the cellar, or push hot air into the cellar.
o
The cold side of the cooling unit must be completely captured inside
the wine cellar.
