Remove old gasket by pulling it directly out of the vinyl gasket retainer. Thoroughly clean 
the gasket area with mild soap and water prior to installing the new gasket. The new 
gasket should be installed by assembling it at the corners first, then working toward the 
center at the top, bottom and sides. The arrow-shaped portion of the gasket should be 
firmly seated in the retainer groove for proper assembly. This can be checked by lifting 
the edge of the gasket and observing the engagement.

In order to get a proper gasket fit, it is important not to stretch gasket material 
during assembly.

1) Turn off the power supply, and unplug the unit.
) Remove the front panel, then remove the wire guard located below the display panel.
3) Unhook the wiring connectors at the control box, then remove the two hex-head M6 

attachment nuts and the M5 bolt. 

4) Very carefully slide out the refrigeration system. Support the evaporator as it clears the 

evaporator case.

5) Remove the connection lead wire for the defrost heater.
6) Remove the two 4×8 T evaporator shroud screws above each end of the defrost 

heater.

7) Carefully remove the defrost heater by twisting the ends together and removing the 

ends from the slots in the shroud.

8) Return the refrigeration unit to its proper position in the reverse order of the removal 

procedure.

9) Plug in the unit, and turn on the power supply.

Be careful when handling both the old and new defrost heaters. The heaters 
are sheathed in glass tubes and can possibly cause cuts if broken. Heater will 
also be hot after a defrost. Use gloves when handling. Avoid touching the glass 
directly; hold the heaters by the ends.
