little to slow the water flow. After the pads are wet – you can open the valve to 1 ¼ turn. Allow water to run for 10 – 15
minutes on new cooling pads to totally saturate them with water. Once your units cooling pads are saturated – then, you are
ready to turn on fan and begin to feel the cooling effect from your new QuietCool. Note: After your cooling pads are broken
in (typically takes 1 -2 weeks in operation) it will take less time to saturate pads for start-up.

5.4 Turn-on Fan

Once your cooling pads are wet – you may turn on your QuietCool unit. Now you can begin to feel the QuietCool difference
in temperature. After your QuietCool has run for 5 minutes or so, visually inspect the pads – if water is dripping outside the
unit – you have too much water, simply turn the water flow valve to the right ½ turn and inspect water flow in another 5
minutes. If there are dry streaks in the cel deck pads open the water flow valve handle ½ turn to increase water – check water
flow in another 5 minutes and adjust accordingly. Most QuietCool operations work effectively with valve opened between 1
½ - 2 turns. This water valve is efficient – it requires minimal turning.

6.0 Daily Operating procedures

6.1 Turn-on water pump
Turn on water pump to unit – let cooling pads get saturated – then turn on fan for cooling. Adjust the water flow –
Your QuietCool operates most efficiently – and maintains uniform cooling pad wetness with the water control valve turned
on at 1 ¼ turns. You must determine what works best for you and your specific environment.

6.2 Adjust water flow

Your QuietCool operates most efficiently – and maintains uniform cooling pad wetness with the water control valve turned
on at 1 ¼ turns. You must determine what works best for you and your specific environment.
6.2 Turn on fan
When you can see that the cooling pads are saturated with water – turn on the fan and feel the cooler air coming from your
QuietCool unit. Adjust the fan speed for your comfort.
6.4 Turn-off unit at end of day
15 minutes before closing for the day – turn off water pump with toggle switch – leave fan running – this action will shut-off
water to the cooling pads while keeping the fan running. The fan will dry out the cooling pads. When the cooling pads are
thoroughly dry – turn off fan. Drying your cooling pads thoroughly - everyday will help prevent mold and mildew growth,
plus it will prolong the life of your cooling pads.

7.0 Maintenance

7.1 Access inside of unit

Turn-off water pump and let the fan continue to run until the cooling pads are thoroughly dry (about 10 – 15 minutes). Once
your cooling pads are completely dry you may turn-off fan. Now unplug electricity to unit to avoid unnecessary shock. Next,
using a 7/16" wrench – remove the two retaining bolts from the backside and topside (cooling pad side) of the unit. These
two bolts hold the metal angle retaining bar and the cooling pads in place. Next, remove the angle retaining bar and set to
side. Now you are ready to remove your unit's cooling pads.
