Water Distribution and Components
Water enters the machine through the float valve located in the water trough. The water trough
holds water used for ice making. The float valve is used to maintain the proper water level in the
water trough. During the freeze cycle water is continuously circulated over the evaporator by the
water pump. When the machine enters harvest, the purge valve (not shown) opens and mineral
laden water is pumped out of the water trough to the drain. After water is purged from the trough,
the water pump and purge valve are de-energized and the trough refills.
Float Valve
The water level can be adjusted by carefully bending the arm of the float. The water level should
be ½ inch (13mm) above the top of the water pump impeller housing during the freeze cycle.
If the float valve does not allow water into the trough or water flow is slow, the float valve may be
restricted. Remove and disassemble the float valve and clean the orifice. If the water flow is still
slow, check the water pressure to be sure it is at least 20 PSI (1.4 bar).
If the float valve does not stop the water flow, make sure the water pressure to the machine does
not exceed 60 PSI (4.1 Bar). Install a water pressure regulator if the pressure is too high. If the
water pressure is not the problem, the float plunger or the entire float valve assembly may need to
be cleaned or replaced.
