ICE Series Refrigeration System
If the refrigeration system is extremely wet, use radiant heat to raise the temperature of the
system. This action will cause the moisture to vaporize at less of a vacuum.
The use of two (2) valves, one between the vacuum pump and gauge manifold and the other
between the refrigerant cylinder and the gauge manifold allows you to evacuate and charge the
system without disconnecting any hoses. If the hoses were disconnected, air or moisture will have
the opportunity to enter the hoses and then the system.
A properly charged icemaker is a service technician's greatest ally. Proper charging will allow any
concern with the icemaker to be accurately diagnosed.
The refrigerant charge must be weighed into the icemaker either by using a charging scale or with
a dial-a-charge.
The amount of proper refrigerant required for the icemaker is printed on the serial data plate
attached to the icemaker and is listed on the following pages. Never vary the amounts from those
listed.
Remote models with sixty (60) foot lineset runs will need an additional fifteen (15) ounces of
refrigerant added.
In some cases the complete refrigerant charge may not enter the refrigeration system. In those
instances, close the gauge manifold high side valve and disconnect the manifold from the high side
port.
When the icemaker is completely charged, secure the caps to the service ports and check to make
sure the ports are not leaking refrigerant.
