CABINET DRAIN –  
 
 

A vinyl drain tube is provided for con-

nection to the condensate pan which is 
mounted to the bottom of the cabinet.  The 
drain must be trapped to guard against the 
drain line freezing, to prevent warm air from 
going up into the back of the case, and for 
good sanitation practice.  A copper tube trap 
is supplied for this purpose. 
 
 

The condensate pan is electrically 

heated.  A separate 115 volt supply with a 
ground rated at 10 amps should be provided 
for this heater.  The heater is supplied with a 
115 volt supply cord with a grounding prong.  
DO NOT REMOVE the grounding prong un-
der any circumstances. 
 
 

The cabinet power switch does not 

shut off the power to this pan.  If the heater in 
the pan should need replacing, be sure to dis-
connect the power source to the pan. 
 
SHELVES –  
 
 

Each cabinet is provided with 3 canti-

lever shelves per door that are adjustable on 1 
inch increments & tiltable.  Each cabinet also 
has one bottom shelf per door.  These shelves 
have one inch legs to allow proper air flow in 
the cabinet.  Behind the shelves are wire flue 
spacers which also allow for proper air flow.  
All shelves and flue spacers are white, epoxy 
coated for durability and ease of cleaning. 
 
 

Care should be taken when loading the 

shelves with product.  Product on the highest 
level of shelves, should not touch the evapora-
tor drain pan.  This pan gets warm during the  
 
 

defrost cycle, and some melting of the product 
may occur if it is touching the pan/ 
 
AIR DISTRIBUTION and REAR 
  FLUE 

SPACER 

 - 

 
 

Air is drawn through the evaporator 

from front to rear and is discharged down the 
back wall, returning up the face of the door to 
the return air grill.  NOTE:  Rear wire grid 
must be in place as this forms a discharge air 
flue at the back of the cabinet                       
 
ELECTRICAL CONNECTIONS –  
 
 

The USL-2 is supplied with a power 

supply cord with a grounding prong.  Do not 
remove the grounding prong under any cir-
cumstances. 
 
 

It is very important for safety to you 

and your customers to have the cabinet prop-
erly grounded.  The electrical installation 
should be done by a qualified electrician in 
accordance with the National Electrical Code 
and/or local codes.   
 

Note:  Connecting this unit to 

any electrical supply other 
than specified on the serial 
plate will void the warranty 
and may result in serious 
damage to the case.  The cabi-
net should be supplied with its 
own service. 

 

SERIAL PLATE INFORMATION –  
 
 

The serial plate is located in the upper 

left hand corner of the case interior.  It has all 
the pertinent information needed for proper 
electrical installation.  The serial plate should 
not be removed for any reason.
