Model 506 (UC Ice Maker)
How It Works (Continued)
When the pump is in harvest cycle, the electric circuit
bypasses the pump pressure switch, and the pump runs
continuously.
At all other times, regardless of any other switch setting
or condition, the pump is on line and will run when the
pressure switch closes.
If pump should fail to run when the pressure switch
closes, it interrupts the circuit to the fill valve so that no
additional water can enter. It also interrupts the circuit
to the hot gas defrost solenoid.

Run the condensate pump power cord through the hole
in the wall and into the unit compartment. Inside the
unit compartment, remove the shunt from the recepta-
cle and plug in the condensate pump.
NOTE:
Do not discard the shunt that is removed from
the receptacle. This shunt must be replaced if the unit
is to be operated later without a condensate pump.
Tape shunt to wall of unit compartment to avoid loss.
Run the discharge line from the pump directly to the
available drain. The FSP condensate pump has a
check valve located in the discharge outlet valve.
Other non-FSP sump pumps may be used with the ice
maker. These pumps are usually located near the
available drain. Run a 5/8-in. I.D. plastic tube from the
drain bin to the pump and a plastic hose from the dis-
charge outlet of the pump into the available drain. If the
pump does not have a check valve on the discharge
outlet valve, one should be installed on the outlet tube.
The sump pump will be plugged into an available power
supply near the drain. A pressure switch inside the
pump will operate the pump as needed, independently
of the ice maker operation. The shunt remains in place
in the receptacle of the unit when a non-FSP sump
pump is used.
