4.1 Control Panel
•
Power Indicator Light – The red Power Indicator Light is located at the bottom-center of the control panel label
and illuminates the Danger High Voltage Triangle. The Power Indicator Light remains ON constantly while
power is applied to the PolarCool unit.
•
Fan Control ON/OFF Button – This button is used to start and stop the fan.
•
+ and – Speed Control Buttons – Used to select the fan speed to any position between LO and HI. These
buttons control the fan speed only and do not turn the fan on or off.
•
Water Pump Control ON/OFF Button – This button is used to start and stop the water pump.
•
Pump ON – The green indicator PUMP ON light is ON solid when the water pump is running.
•
Low Water – The red indicator LOW WATER light is ON blinking when the water level is low for less than 1
minute. After the first minute, the red indicator light is ON solid.
•
Fill – The green indicator FILL light turns ON blinking when the water level has remained low for a constant
time of more than 1 minute. Also after the first minute of constant low water level, the water pump will
automatically turn off, the Pump ON and Fill green indicator lights will be blinking, and the Low Water red
indicator light will be ON solid.
NOTE: The water must be filled above the low level switch and remain above the switch for a minimum of 1
minute solid before the water pump will turn back On.
4.2 Valves
Spray Bar Adjustment Valve– Used to adjust the water flow to the spray bar. The valve can be opened or
closed to increase or decrease the water flow to the pads. Too much water can allow droplets or a mist to
be blown out of the fan. Too little water will prevent thorough wetting of the pads and will result in a
reduction in cooling efficiency. Refer to section 7.9 for flow adjustment details and instructions.
Auxiliary Water Supply/Cut Off Valve – The Zone is equipped with an additional water supply outlet. The
outlet is located on the opposite side of the unit from the inlet tap, and is regulated by a cut off valve
located near the outlet (See Figure B, page 6). There are two primary uses for the auxiliary water supply
outlet:
1. Attaching a water hose to the outlet and opening the cut off valve allows the water
supply to be available even as the Zone operates. The water hose can then be used
for spraying off the pads, general maintenance, etc. (See Figure A, page 6)
2. The extra water hose can also be used to link one PolarCool Zone to another,
eliminating the need for multiple water sources when more than one PolarCool is
being used.
