Thermostatic Mixing Valve; Thermostatic Stop And Check Valves; Thermostatic Temperature Adjustment - Reeves G2 Operation & Maintenance Manual

1.3.2 Thermostatic Mixing Valve

The mixing valve is carefully assembled, tested at the factory, and set to deliver water at any temperature between full
cold and 110 degrees F. Failure of the cold water supply will cause the hot water seat to close. The label on the valve is
marked "Hot-Cold', so that the handle can be set accordingly. When the unit is not being used, turn the handle towards
the Cold position fully to shut off all flow.

1.3.3 Thermostatic Stop and Check Valves

At each inlet of the valve, there is a screwdriver operated check valve. Both the cold and hot water stop and check valves
must be open at all times for proper function of the valve. These stops are checked and opened fully before the unit is
shipped.

1.3.4 Thermostatic Temperature Adjustment

Units are preset for maximum temperature of 110 degrees F. If a temperature adjustment is needed, follow the steps
below. Failure to follow these steps properly will void the valve warranty and can cause serious damage.
1. Remove handle screw.
2. With narrow blade, screwdriver, turn the adjusting knob #5, clockwise to reduce maximum outlet temperature and
counterclockwise to increase maximum outlet temperature. This must be done with the valve handle in the hot
position, turned counterclockwise. Screw should not be turned more then ½ turn at a time without testing water
temperature.
3. When temperature is correct, replace handle screw.
CAUTION: It is not recommended to set the maximum outlet temperature above 110 degrees F.
NOTE: Adjusting screw #5 may not be turned counterclockwise more than 1 ½ turns.
