Cleaning Water Pump & Hose
CAUTION:
Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler. If
the cooler is thermostatically
controlled, the thermostat is
not to be used as the power supply disconnect, as it may
reset and start the unit unexpectedly
.
CAUTION
: Do not allow pump to fall over and become
submerged; water will damage pump motor.
Clean water pump and hose assembly as follows:
Unplug pump cord, remove
mounting bracket screw and
remove pump from cooler. Shake
gently to remove water.
To prevent breakage, carefully
release the snap-out impeller
cover plate and remove cover
plate from the pump body.
Using a mild detergent solution and a soft
cloth, clean deposits from screen, around
impeller and cover plate. Spin impeller to
dislodge any remaining foreign material.
Remove any foreign material in the hose adapter
(between the pump and hose), or between the
hose and the water distributor assembly.
Rinse and reinstall impeller cover plate.
Reinstall pump and reconnect pump cord.
Touch-Up
The hardness, adhesion and smoothness of our Peblar XT®
appliance-type finish on the internal and external surfaces of your
cooler makes it extremely unlikely that scratches or chipping will
occur. Your cooler's long lasting finish can be brought to like-new
condition by using warm water and a soft cloth.
NOTE: Avoid using scouring pads, steel wool or wire brushes, as
these will damage the finish and encourage corrosion.
In the event that finish damage does occur, it should be promptly
repaired by the following procedures:
1.
Sand the area around bare metal spots.
2.
Prime and paint with a quality paint.
Do not use asphalt type cooler undercoat material in water
reservoir.
Lubrication
Motor Bearings
Some
motors used in Pro-series coolers have ports for lubricating
the motor and are oiled at the factory. If the need for oiling is indicated,
see individual motor nameplate for specific instructions on re-
lubricating the motor. Under normal use, these motors require oiling
about every 12 months of operation.
Do Not Over-Oil
.
Blower Shaft Bearings
Blower shaft bearings need periodic lubrication. They should be
checked 20-30 days after initial start-up of operation. The oil cups on
the bearings should be filled with a good grade of SAE 20W or 30W
non-detergent oil when necessary. Under normal use, oiling is
required every three months of operation.
Do Not Over- Oil.
Pump Motor Bearings
The pump motor does not require lubrication.
MAINTENANCE SCHEDULE
Regular maintenance and periodic inspection is the key to long and
successful service from your Pro-series cooler. The cooler should
receive major servicing at least once a year, more often if conditions
require (dusty environment, constant use, poor water quality, etc.) For
maximum cooling efficiency, long life and appearance, every two
months during operation, the cooler should be inspected and cleaned.
NOTE: Do Not Undercoat the Water Reservoir
The parts of your cooler that are in contact with water are protected by
plastic liners. The plastic surfaces should be very easy to clean, but
care must be taken to avoid damaging them. All foreign materials,
mineral scale, hard water deposits, dirt, etc. should be removed from
plastic liners, water pan and other components by using warm water
and a soft cloth. Use of any asphalt ‘cooler coats’ or other types
undercoating may damage the plastic and will void your warranty.
NOTE: Do not use cooler cleaners, cooler treatments, anodes or other
chemical additives in this evaporative cooler. Use of any additives or
water treatment other than the furnished bleed-off will void your
warranty and may impair the life of the cooler.
Before starting any maintenance operation, thoroughly read all
operating and maintenance instructions and observe all
cautions and warnings.
Cleaning
CAUTION:
Never wash your cooler cabinet with a
garden hose; water may harm motor and pump or seep
into ductwork. Motors damaged by water are NOT covered
under warranty.
All foreign materials, mineral scale, hard water deposits, dirt, etc.
should be removed from pad frames, water pan and other
components. Your cooler's long lasting finish can be brought to like-
new condition by using warm water and a soft cloth.
Maintenance & Inspection
IMPORTANT:
Before operating cooler at the beginning
of each cooling season, turn blower wheel, cooler motor
and pump motor shafts by hand to make sure they turn
freely. Failure to do so may result in burning out motor.
Periodic inspection of your cooler will enhance the chance for long,
trouble-free service life. For maximum efficiency, every two months
during operation, or any time the cooler is opened, the cooler should
be inspected. Some suggested items to look for:
P
Check for leaks from water lines, cabinet, etc.
P
Any dry spots or streaks on pads when pump is operating?
P
Are bolts, nuts and set screws still snug?
P
Are the bearings, etc., making any unusual noises?
P
Does the blower wheel turn freely?
P
Is float level set correctly?
P
Is water in the bottom pan clean?
P
Belt condition / tension / alignment OK?
Adjust Belt Tension
Each time you inspect your cooler, be sure to check belt tension on
motor and blower assembly. Check belt condition and replace it if
frays or cracks appear. Check alignment of blower pulley with motor
pulley
Draining
Drain the cooler (with power off and pads removed) as follows:
Connect a drain hose to the drain fitting on the bottom of the
reservoir, if not already connected to drain line.
Remove overflow standpipe from the drain fitting.
Drain and clean reservoir (avoid draining water onto a roof,
mineral build-up or damage to roof may occur).
(see page 4 for detailed steps).
