USE & OPERATION
CLEANING & MAINTENANCE
!
Periodic Drying of Pads.
For best results allow pads to
dry after each operation by turning off the pump 15 minutes
before turning off the fan blower motor.
Periodic Draining of Sump.
The entire water sump
should be drained at least once weekly to reduce mineral build-
up. The failure to regularly drain the entire water sump will
greatly increase the mineral deposits and reduces the expected
life of the cooling pads. This could result in early replacement
of the pads at the owner’s expense. Use a damp cloth and wipe
off any mineral deposits that appear outside or inside the unit
at least once per week of use.
Lubrication.
The pump and blower motors do not require
lubrication. For belt driven blower wheel models only, the
blower shaft bearings need periodic lubrication. The oil cups
on the blower shaft bearings should be filled with a good grade
SAE20W or 30W oil when necessary. Under normal use, oiling
is required every three months of operation. DO NOT OVER OIL.
Cleaning Water Pump.
(Pictures 5 and 6) Disassemble
and clean the water pump as follows.
•
Disconnect power supply to the cooler.
•
Access the pump by lifting the pad frames up and out of
the cooler. Remove pump from cooler.
•
To prevent breakage, carefully release the four snap-out
tabs and lift impeller base plate from the pump body.
(Picture 5)
•
Use a mild detergent solution and wash all deposits from
the inside around the impeller and impeller base plate.
•
Spin the impeller to dislodge any foreign material.
(Picture 6) Rinse and reinstall impeller base plate.
•
Reinstall pump into the cooler.
CAUTION
Do not allow the pump to fall over and
become submerged in the water. Water
will damage the pump motor.
1. Turn on the water supply to the cooler. The hose concection
to the float valve provides an automatic method of refilling
the water supply as water evaporates.
2. For best results, turn the pump on a few minutes before
turning on the blower fan. This allows the cooling pads to
pre-wet for best efficiency.
3. When cooling is not required you can operate the unit as a
fan by turning on the blower fan only and leaving the pump
turned off.
4. The water can be adjusted by tightening or loosening the
clamp that pinches the water supply tube. Adjust the water
flow clamp so that adequate water is supplied to the pads
without excess water splashing out of the trough during
normal operation.
CAUTION
Do not operate the unit with pads or
grille removed.
CAUTION
Unplug the electrical cord to the cooler
before attempting to work on or service
the cooler.
