USE & OPERATION
1. If your model has locking casters, make sure the two
locking casters have been locked to prevent the cooler
from moving before turning on the fan.
2. Turn on the water supply to the cooler. The hose connection
to the float valve provides an automatic method of refilling
the water supply as water evaporates.
3. 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.
4. Whenever possible, operate the blower fan at low speed for
maximum cooling. 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.
CLEANING & MAINTENANCE
Periodic Drying of Pads.
dry after each operation by turning off the pump 15 minutes
before turning off the fan blower motor.
Periodic Draining of 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.
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.
