CHECKOUT
1.After mounting and wiring has been completed, set thermostat switch to “OFF” position and fan switch to “LO” position. Turn thermostat lever to “5” and thermo-
stat switch to “COOL”. Nothing should happen pro- vided the room temperature is below 95°F.
2.Turn thermostat lever to “1”. The pump should start
immediately, provided the room temperature is above 55°F.
3.After a time delay of 30 to 120 seconds to allow the cooling pads to become soaked, the fan should start running at low speed.
4.Turn fan switch to “HI” position. The fan should now be operating on high speed.
