TROUBLE SHOOTING GUIDE
1. If unit is inoperative, check:
a.
Circuit breakers
b.
Line fuses
c.
Voltage at starter
2. If insufficient cooling occurs, check:
a.
Visually check pump operation.
b.
Water system obstructions.
3. If low airflow occurs, check:
a.
Blower belts slipping
b.
Improper motor sheave setting
c.
Evaporator or filter pads plugged up
d.
Excessive ductwork resistance
e.
Blower motor horsepower too low for requirements.
4. If there is mineral buildup on evaporative pads, check: (Evaporative only SE and DE)
a.
Insufficient bleed off water
b.
Bleed line plugged
c.
Insufficient water over pads (hardness of water may necessitate more frequent cleaning
and/or pad replacement).
MAINTENANCE AND CLEANING FOR EVAPORATIVE
COOLING UNITS
WARNING: Use care when working around live voltage, failure to do so may
result in
severe injury or death for which ARES will not be responsible.
1. The reservoir pan should be drained and cleaned at least once every cooling season and before
every winter operation; clean pans more often if water conditions require it.
a.
Remove the overflow standpipe and allow water to drain.
b.
Clean out all sediment and if necessary, paint bare metal or scratches with protective paint
or undercoating.
c.
Water distribution troughs must be unobstructed.
2. Inspect cooling filter media monthly for mineral deposits (in hard water areas, mineral salts will
build up quickly).
Be sure filter media is clean and does not obstruct airflow during winter operations.
3. The need for changing filter pads more frequently varies with locality, particularly areas where dust,
alkali and other foreign matter accumulate in the pads.
a.
To change filter pads, use ARES filter pads #987360 Coolpad or O5915 Glacier-Cor
®
for
evaporative cooling.
b.
Lay louvered panels on a flat surface with wire filter retainers face up.
c.
Remove the center frame support and the filter retainers by pressing down on each end of
the retainers to disengage hooks from the holes in the pad frame.
d.
Remove and discard used filter pads. Clean and paint all bare surfaces as needed. Check
slots in the water distribution trough to be sure that they are open and free of obstructions.
Evaporative units only (See illustration on next page top right).
e.
Install a new filter pad in the frame. Check that the pad is of uniform thickness
and completely fills the frame to avoid air bypass.
CAUTION: Automatically Operated Device - To Reduce the Risk of Injury, Disconnect From Power
Supply Before Servicing.
