Water Connection
• Install overflow assembly. Remove nut and place nipple through
the hole in the pan, with the rubber washer between the pan and the
head of the drain nipple (Fig. 5). Screw
on nut and draw up tight against bot-
tom of pan. Insert overflow pipe in
nipple to retain water. Overflow pipe
may be removed to drain pan when
necessary. A garden hose may be
screwed on the drain nipple to drain
water away from your unit.
• Connect water supply line. Find
the closest supply of water. Use a
saddle valve (Fig. 6) to connect 1/4"
tubing to the cold water supply or
use a Sillcock and water valve
connected to an outside faucet (Fig.
7). Place the nut and ferrule on the
tubing and tighten the nut until
water tight. IMPORTANT: Do
not connect the water supply to
any soft water applications. Soft
water will cause corrosion and
decrease the life of the cooler.
• Attach water line to float. At-
tach the water supply line to the
float in the same manner as above.
The float may be installed in either
the corner post or bracket (Fig. 8).
• Fill pan. Allow water to fill to within 1" of top of pan and adjust
float to maintain this water level. This can be accomplished by
bending the float rod.

• Level water troughs. Operate
pump until pads are saturated.
Check each trough to see if water
is evenly dispersed in the trough.
If they are not, loosen adjustment
bolts and level trough. Retighten
bolts. Check to see that all pads
are saturated with water and that
there are no dry spots or open-
ings in the pads.
Amperage Draw And Belt Tension
This unit is equipped with an adjustable motor drive sheave for
adjusting the blower wheel speed to the proper loading on different
duct systems. It is important that the motor drive pulley is adjusted
to correct size to assure maximum air delivery without damage to the
motor. Be sure to follow these instructions carefully.
• Adjust drive pulley. After the unit is completely installed, adjust
the drive pulley to the least diameter and adjust belt tension. See
the maintenance section for adjusting belt tension.
• Start cooler. Install all pad frames, start pump, and allow to
operate until pads are wet.
• Check amperage. With pads wet and unit started, check amper-
age draw with an amperage meter.
• Adjust pulley if necessary. If amperage draw is less than motor
rating, turn off electrical power and remove pad frame. Unplug
motor inside cooler, this will protect you from someone turning on
unit while you are working inside. This should be done for your
safety. Adjust pulley to a larger diam-
eter and readjust belt tension, plug
motor in, install pad frame, and retest
amperage draw. Repeat this process
until correct amperage draw is attained.
Increasing motor pulley diameter in-
creases amperage draw. Decreasing
motor pulley diameter decreases am-
perage draw (see Fig. 9).
CAUTION:
Do not operate cooler with larger amperage
draw than specified on motor plate.
NOTE: No attempt should be made to completely install this unit
without the aid of an electrician or someone familiar with testing
amperage draw. Failure to comply with these instructions may void
your warranty.
Maintenance
WARNING
: Before doing any maintenance be sure power
is off. At the time you remove a pad frame be sure to unplug
motor and pump. This is for your safety.
Spring Start-Up
• Oil bearings. The blower bearings and cooler motor in this unit
should be oiled with a few drops of non-detergent 20/30 weight oil
once each year. The motor does not need oil if it has no oil lines for
oiling. Motors that have no lines are lifetime oiled at the factory
and require no further oiling for the life of the unit.
CAUTION:
Do not over oil. Over oiling can cause motor burn
out, due to excessive oil getting into motor winding.
