them to become brittle and prevent proper seals.  Also, never 

use sharp tools or knives to scrape or clean the gasket which 

could possibly tear the gasket and rip the bellows.

Gaskets can easily be replaced and do not require the use of 

tools or authorized service persons.  The gaskets are “Dart” 

style and can be pulled out of the grove in the door and new 

gaskets can be “pressed” back into place.

Over time and with heavy use doors the hinges may become 

loose.  If it is noticed that the door is beginning to sag, it may 

become necessary to tighten the screws that mount the hinge 

brackets to the frame of the unit.  If the doors are loose or 

sagging this can cause the hinge to pull out of the frame which 

may damage both the doors and the door hinges.  In some 

cases this can require qualified service agents or maintenance 

personnel.

If it becomes necessary to adjust a door, follow these 

instructions:

1.  If the door needs lowering at the handle, use a 5/16” wrench 

to loosen the hinge screws and install a spacer outside of 

the hinge (see illustration 1). Tighten the screws.

2.  If the door needs to be higher at the handle, use a 5/16” 

wrench to loosen the hinge screws and install a spacer 

inside of the hinge (see illustration 2). Tighten the screws.

Each unit has a drain located inside the unit which removes the 

condensation from the evaporator coil and evaporates it at an 

external condensate evaporator pan.  Each drain can become 

loose or disconnected from moving or bumping the drain.  If 

you notice excessive water accumulation on the inside of the 

unit be sure the drain tube is connected from the evaporator 

housing to the condensate evaporator drain pan.  If water 

is collected underneath the unit you may want to check the 

condensate evaporator drain tube to be sure it is still located 

inside the drain pan.  The leveling of the unit is important as the 

units are designed to drain properly when on a level surface, 

if your floor is not level this can also cause drain problems.  

Be sure all drain lines are free of obstructions, typically food 

product is found blocking drain lines causing water to back up 

and overflow the drain pans.

Service Alert
During normal operation the evaporator fan may cycle 

and/or pulse independently of the compressor. Consult 

the service manual or contact Technical Support at 

1-888-732-2446 if you are unsure of the proper function.
