Leg And Condensate Pan Installation; Service Instructions - Master Bilt IHC-27 Installation & Operation Manual

LOW TEMPERATURE FREEZERS – "IHC" Models
The power cords are rated 15A, 120 Volt for the IHC-27 and 20A, 120 V for the IHC 48 and are located 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

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.
