INSTALLATION INSTRUCTIONS

 

  
GENERAL INSTRUCTIONS 
 
1.  Be sure the equipment is properly installed by competent service people. 
 
2.  Keep the equipment clean and sanitary so it will meet your local sanitation codes. 
 
3.  Rotate your stock so that older stock does not accumulate.  This is especially important for ice  
cream.  A "First-In, First-Out" rotation practice will keep the products in good sellable condition. 
 
4.  Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the 
case for at least 6 hours after it is started. 
 
5.  Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of 
time. 
 
6.  When replacing burned out fluorescent tubes, be sure that the electrical power to the lighting circuit is 
turned off. 

 
 

 

 

 

 

   

 

NOTICE TO STORE OWNERS / MANAGERS 

 

Moisture or liquid around or under the cabinet is a potential slip/fall hazard for persons walking by or 
working in the general area of the cabinet.  Any cabinet malfunction or housekeeping problem that 
creates a slip/fall hazard around or under the cabinet should be corrected immediately.

 

 
If moisture or liquid is observed around or under a Master-Bilt cabinet, an immediate investigation should be 
made by qualified personnel to determine the source of the moisture or liquid.  The investigation should 
determine if the cabinet is malfunctioning or if there is a drainpipe leaking. 

 

ELECTRICAL 

 

 
WARNING 
 

Before servicing electrical components in the case, make sure all power to case is off.  Always use a 
qualified technician.

  

 

 
ELECTRICAL INFROMATION AND GROUNDING 
 
A separate circuit for each cabinet is recommeded to avoid the possibility of other appliances on a 
circuit to one of these cabinets overloading that circuit and causing malfunction.  The electrical service 
should be grounded upon installation. 

 

MECHANICAL

 

 

LEVELING CABINET 
 
Level the cabinet so as to insure proper drainage of the drain pan and proper operation of the  lids and 
refrigeration system.  The GT cabinet condenser has cooling air entering and discharging through the front 
grille.  This allows the cabinet to be placed against a wall or solid object without blocking the flow of condenser 
air.
