SOLUTION
If the freeze heads are not cold to the touch after 7-
10 minutes, turn the unit OFF. Keep the unit OFF
for 2-3 minutes, then restart.
Make sure of proper power supply without any in-
terruption & compressor fan running.
Check that there is unrestricted air circulation to the
condenser unit. Check the condenser unit's inlet air
ports, If they are dirty or blocked; clean them with
shop air while the unit is running.
Contact Technical Service Department at Ridge
Tool. (See Service and Repair) .
Check for water flow. If this exists, stop the flow.
Use the water spray bottle to build an ice bridge and
provide the contact for heat transfer. The slightest
air gap will prevent freezing.
Make sure system is full of water.
Pipe freeze unit will not work.
Allow system to cool off or freeze heads are too
close to circulating main-stop circuit.
After freeze head is frozen to pipe, wrap with insu-
lation.
The compressor is thermally protected, It will take
time for automatic restart.
