INTRODUCTION

Evaporative cooling works on the principle of heat absorption
by moisture evaporation. Simply put, heat is removed from the

ir as water evaporates. You feel this principle in action when

a
you step out of a swimming pool or shower; you feel immedi­ately cooler as water evaporates from the surface of your skin.

!

WARNINGS AND SAFETY RULES

WARNING…

To reduce the risk of electric shock, fire or injury:

• Read instructions and labels carefully.

Always unplug the electric cord to your cooler before

•
you work on the cooler.

• Your cooler will run on 120 Volt AC, 60 Hz (cycle)
current only.

Your evaporative cooler works on the same principle. Hot out­side air is pulled through water-saturated pads, where the air is

ooled by evaporation and then discharged from the cooler. In

c
order for your cooler to work at maximum efficiency, it must
have hot air to draw in (from an open door or window) and an
outlet to vent out the air (window or vent). To learn more about
evaporative cooling, visit our website at www.AdobeAir.com.

LOCATION

Always make sure the unit is operated on a level surface. The
best location for it is near a partially opened window or door
where hot outdoor air can be drawn into the unit. This cooler is
portable, but use caution when rolling the unit to avoid splash­ing and spilling of water. Cool air can best be directed through
the space by using a partly opened window or door
that is situated on the opposite side of the

through the space and exhausted back outdoors which is
critical to proper performance of the cooler.

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.

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.

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 build­up. 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.

• 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.

• 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.

COOLING PAD REPLACEMENT

The cooling pads should be changed at least every two years.
Check and clean them at the beginning of the season and
clean and reverse them in the middle of the season. The pads
may need to be replaced more frequently depending on local
conditions and the maintenance schedule followed.

Replacement Instructions:

To remove pad assemblies from the unit, lift up, pull out and then
down. Lay the metal side down on a flat surface and remove the
pad retainers. The MasterCool pad can now be removed. Rinse
off pad assembly, then install new MasterCool pad and retainer.
Replacement filter pads are available at your cooler dealer. See
pictures 7-10.
