3. FREEZING WATER CIRCUIT
n. FLOAT VALVE
The float valve, see Fig. 18^ meters the make-up
water which is circulated to the freezing columns
and can be observed by removing the front panel
and inner access door.
The float valve can be adjusted by loosening the
wing nut and the set screw and adjusting the con­
necting arm. Raising the float will raise the water
level, and lowering the float will lower the water
level. The water level should be approximately
1/2" below the top of the siphon standpipe for
the 26H5 units, and 3/8"below for the 26H3 units.
C A U T I O N : After adjusting the float with the set
screw, tighten the wing nut. If the float works
loose, water will overflow through the siphon stand­
pipe and cause an extremely long freezing time and
a continuous siphoning action.
To replace the float valve;
a. Close the water supply valve.
b. Remove front panel and inner access panel.
c. Remove float from valve by taking out wing
nut. This float valve can be removed from
the front by turning the valve body counter­
clockwise.

12. WATER DISTRIBUTOR
The water distributor feeds the freezing columns
and should be checked to insure that the discharge
nozzles are clear. Water flow from all ports should
be approximately the same. To inspect the headers,
disconnect the rubber hose (s). Remove the three
screws which hold the header assembly and sup­
port brackets in place and lift the header from the
top of the machine compartment. See Fig. 19.
