Operation Of Cooler; Maintenance Instructions - Seeley Breezair EAS265 Installation Manual

It is important to recheck the motor
amps again after re-setting the belt
tension. Correct belt tension ensures
the belt will not slip. Check the
temperature of the belt by hand after
each adjustment, by turning off the
cooler and holding one side of the
belt in your hand. If the belt is warm
to touch, it is slipping! Continue to
tighten until it runs cool. (fig. 24)

Bleed Off
See previous heading "Overflow and
Bleed-Off feature" under "Water
Installation".
Adjusting the bleed rate is necessary to
reduce the salt deposit on the pads.
Salt deposit can NEVER be entirely
eliminated, only the rate of deposit
can be changed. The bleed feature
causes some salt concentrated water in
the pan to be drained away. Fresh water
enters the cooler automatically as the
salty water exits.
The rate of bleed will vary according to
water quality, but should be set to a
minimum rate as set out below:-
EA148 (small cabinet): 0.05 gpm
EA265 (med. cabinet):
EA385 (large cabinet):
NOTE! Bleed adjustment cannot be
precise as operating conditions vary
continually.
NOTE ! Previous warning about running
coolers without bleed-off.

OPERATION OF COOLER

Using your Cooler
Evaporative air coolers always function
on 100% fresh outside air.
Therefore you must either open doors
and windows, or, provide exhaust
outlets in the building. FAILURE TO
PROVIDE ADEQUATE EXHAUST
OPENINGS WILL CAUSE A BUILD UP
OF HUMIDITY INSIDE THAT WILL
BECOME VERY UNCOMFORTABLE.
Start up
Turn on the water supply and make
!
sure the shut off valve at the cooler is
also on.
Turn on electrical power supply.
!
Wait a few minutes for the water to fill
!
the cooler pan.
Turn on "cooling" at the wall control to
!
start the pump and pre-wet the pads.
Turn on the fan to High or Low speed
!
as desired.
In humid weather you may feel more
!
comfortable by turning off the cooling to
run the fan only.
You can create your own pattern of air
!
flow in the building by adjusting the
outlet vents and doors and windows to
direct the air where you want it.

performance, damage to, or safety of
the air cooler when alternative pads
are used. Using poor quality or
incorrect pads may cause water
carry-over that might enter electrical
components creating an electric
shock or fire hazard.
If the pads are re-used they can be
easily cleaned by hosing them with
clean water, but do not use excess
pressure because you might create
holes in the pad media.
All maintenance must be done
