LOW TEMPERATURE FREEZERS – “IHC” Models
The IHC has a power cord (15A, 230 Volt) on top of the cabinet at the right rear for connection to power. On initial
start-up the evaporator fan motors will not start and you cannot initiate a defrost until the evaporator coil temperature
has lowered to 25
°
F. This is due to the thermostat. Also, the cabinet comes with a non-adjustable “Front” control to
keep the mullion heaters off until the cabinet temperature has lowered to 10
°
F.
LEG AND CONDENSATE PAN INSTALLATION FOR TOP MOUNT CABINETS ONLY
1. Screw legs into existing crate mounting holes.
Condensate Heater Pan (IF PROVIDED)
Mount pan and bracket assembly to rear of cabinet with
2 large sheet metal screws (supplied). Be sure pan is
located directly under cabinet drain.
Condensate Pan Assembly (OPTIONAL)
1. Place the condensate drain pan (evapoway pan) level behind
or slide under the IHC cabinet.
2. Route the drain line of the cabinet to the pan so the water
can drip into the pan during defrost.
* Do not let the drain tube touch the drain pan’s heater. It
can melt the tube or even catch it on fire
.
3. Plug the drain pan into a separate 115V power supply.
