Maintenance Schedule; Replacement Parts - PMI WH2906 Manual De Uso Y Cuidado

MAINTENANCE SCHEDULE

Regular maintenance and periodic inspection is the key to long and
successful service from your 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
Your cooler's water reservoir is finished with our Peblar XT®
appliance-type finish. It is so hard that asphalt-type cooler water pan
under-coatings will not stick to it. Undercoating will break free,
clogging the pump and water distribution system.
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
inside the house through the window duct. Motors
damaged by water are NOT covered under warranty.
All foreign materials, mineral scale, hard water deposits, dirt, etc.
should be removed from pad frame, 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.
NOTE: Avoid using scouring pads, steel wool or wire brushes, as
these will damage the finish and encourage corrosion.
Maintenance & Inspection
IMPORTANT:
Before operating cooler at the beginning
of each cooling season, turn blower wheel and pump
motor shaft by hand to make sure they turn freely. Failure
to do so may result in burning out motor.
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:
Check for leaks from pad frames, cabinet, etc.
Any dry spots or streaks on pads when pump is operating?
Are the bearings, etc., making any unusual noises?
Does the blower wheel turn freely?
Is float level set correctly?
Draining
Drain the cooler for cleaning or at the end of the season as follows:
Push "COOL" and "FAN" switches to the "OFF" position. Turn off
water supply to cooler.
Remove the pad frame assembly and disconnect the pump hose
from the water distributor (located at the inside top of the cooler.
Place end of hose outside of unit for draining, keeping in mind the
amount of water to be discharged.
Turn cooler pump on by pushing "COOL" switch to the "ON"
position, pumping water out of cooler pan. Switch pump "OFF"
when no more water can be pumped out. Unplug cooler power
supply cord from wall receptacle.
Remove any remaining water with a sponge or rag.
Replace pump hose on water distributor, reinstall pad frame
assembly into cooler.

Cleaning Water Pump & Hose
CAUTION:
Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
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 power supply cord from
wall receptacle, remove pump
mounting bracket screw and
gently lift 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 power cord.
Touch-Up
The hardness, adhesion and smoothness of the internal and external
finish on your cooler makes it extremely unlikely that scratches or
chipping will occur. 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. Undercoat will break free, clogging the pump and
water distributor.
Lubrication
Blower Motor and Pump Motor Bearings
The blower and pump motor bearings do not require lubrication.
Grille Cover
Model HE2913 is supplied with a grille cover. This cover is used
during periods of non-use or for winterizing your cooler.
Flexible tabs on each side hold the cover in place over grille. Pull side
tabs out and forward to install or to remove cover from grille.
Winter Shut Down
- Always drain all of the water out of the cooler and water supply line
when not in use for prolonged periods, and particularly at the end of
the season. Keep the water line disconnected from both the cooler
and the water supply so it does not freeze.
- Disconnect power from cooler during extended periods of non-use.

REPLACEMENT PARTS

When ordering replacement parts, always refer to the serial and
