Do  not  place  product  in  cases  until  it is at proper  operating  temperature.  Air discharge  and return  flues 
must  remain  open  and  free  of  debris  or  obstruction  at  all  times  to  provide  proper  refrigeration  and  air 
current performance. Do not allow any product, signs, debris, etc. to block these grilles. Do not use any 
non-approved shelving, display racks or any accessory that could hamper air current performance.

 

WARNING!

 

Do not walk on top of the cases!

 This could result in damage to the case and serious 

personal  injury  could  occur. These  cases are  not  designed  to  support  excessive  external  weight.  Do  not 
use top of cases for storage. 

Normal Operation 

Below are the different operation methods for our cases. Cases vary depending on application and how 
they were specifically ordered. Review the data plate on your cases and refer to the Case Data previously 
listed in this manual for your models specific information. 

1.

 

Off-Cycle Defrost. The fans run continuously and defrost termination is by termination Klixon.  

2.

 

Electric Defrost models are optional. Electric heaters are utilized to melt the frost and ice on the 

coil. The  heaters  are located  in the  air  stream  in  front  of  the  coil. The  defrost  cycle  is time 
initiated and should be temperature terminated. Case fans operate continuously in defrost and 
refrigeration.  As  a  safety  precaution,  a  safety  cutoff  Klixon  is  wired  in  this  series  with  the 
defrost heater set to turn the heater off at temperatures above 70°F.  

3.

 

Hot  Gas  Defrost  models  are  optional  for  parallel  compressor  operation  only.  Hot  gas  is  routed 

through  the  suction  line  and  evaporator  coil.  It  exits  the  coil  through  a  by-pass  around  the 
expansion  valve  and  heat  exchanger,  in  order  to  return  to  the  liquid  line.  The  condensed 
liquid is then used to feed the other cases on the parallel case. The display case’ fans continue 
to operate during defrost to warm up the drain pan and air ducts. The defrost cycle is time-
initiated and should be temperature terminated.  

4.

 

Single Condensing Case Systems. A thermostat should be used to control case temperatures. The 

thermostat bulb should be mounted in the discharge air. 

 

 

NOTE

: Heat exchangers are standard in hot gas defrost models. They aid in increasing operating 

efficiency and reducing frosting and flood-back to the compressor. Heat exchangers may not be used if 
mechanical subcooling is incorporated in the system design. 

Cleaning 

As  a  general  rule, always use  mild soap  and  water to  wipe  the  case down.  Special  precautions  must  be 
taken when cleaning some components of the case. 
Exterior surfaces should be cleaned with warm water and mild soap to protect and maintain the finish. 

Do 

not  use  cleaners  containing  abrasive  materials  or  ammonia,  which  will  scratch  or  dull  the  finish.

 

The waste outlet should be flushed with water following each cleaning. 
Interior surfaces may be cleaned with most  mild soap formulas, as well as ammonia based cleaners and 
sanitizing solutions. These cleansers should not harm the interios surface. 

   

WARNING!

  Always  shut  power  off  during  the  cleaning  process.  Cleaning  the  case  with 

electrical power applied is a shock hazard that may cause serious injury or death.
