Water Inlet: 

Air Cooled Models:

 The recommended water supply is clean, cold water.  Use 3/8 inch O.D. copper tubing,   

connect to the 3/8 inch FPT at the back of the cabinet.  Install a hand valve near the machine to control the 
water supply. 

Water Cooled Models:  

A separate 3/8 inch O.D. copper line is recommended, with a separate hand valve to 

control it.  Connect to the 3/8 inch FPT condenser inlet at the back of the cabinet.  The water pressure to all 
lines must always be above 20 psig, and below 80 psig. 

Water Treatment:

  In most areas, a water filter of some type will be useful.  In areas where the water is 

highly concentrated with minerals, the water should be tested by a water treatment specialist, and the 
recommendations of the specialist regarding filtration and/or treatment should be followed. 

 

Drains: 

Air Cooled Models:  

Connect a rigid drain tube to the ¾ FPT drain fitting at the back of the cabinet.  The 

drain is a gravity type, and a ¼ inch per foot fall is the minimum acceptable pitch for the drain.  There should 
be a vent at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented 
floor drain.  Use only ¾ inch rigid tubing. 

Water Cooled Models:  

Connect a separate drain line to the ½ inch condenser drain connection at the back 

of the cabinet.  Do not vent this drain. 

Storage Bin: 

Connect a separate gravity type drain line to the ice storage bin drain.  Vent this drain if there is 

a long horizontal run from the bin to the floor drain.  Insulation of this drain line is recommended.
