tubing and tighten the nut until wa-
ter tight. IMPORTANT: Do not
connect the water supply to any
soft water applications. Soft wa-
ter will cause corrosion and
decrease the life of the cooler.
• Install float and attach water line
to float. The float may be installed
in either the corner post or bracket
(see Fig. 8). Refer to figure 9 for
installation instructions. Insert
the float (1) thru the hole in the
corner post or bracket. Install
the washer (2) and nut (3).
Tighten to keep the float from
turning. Place the nut (5) and
ferrule (4) on the water supply
line. Connect to float fitting and
tighten until water tight.
• Fill pan. Allow water to fill to
within 1" of top of pan and ad-
just 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 openings 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 ad-
justed 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
diameter 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 amper-
age draw (see Fig. 10) .
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

• Clean pump. Cleaning the pump is necessary once a year at
start-up. For your safety, turn unit off and unplug motor and
pump. Remove the pump from the mount slot. Remove the base
of the pump as shown in Fig. 11. Clean the pump and turn the
impeller to ensure free operation. Remove the pump spout and
check for any blockage. After cleaning, reinstall the base onto the
pump. Reattach the pump to
the mount in the cooler using
the plastic retainer to ensure
that the pump will not overturn.
Do not forget to replace the
spout and water delivery tube
onto the pump outlet. The
pump has an automatic reset
thermal protection.
• 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.
• Change Pads. The pads should be replaced once or twice a
season, depending upon the length of the season. At the beginning
and at mid season a clean pad is more absor-
bent and efficient and will deliver
substantially more cool air.
• Check belt tension. A 3 lb. force
should deflect the belt 3/4 inches (see
Fig. 12). Readjust belt if needed.
• Check bleed-off valve to be sure it is not clogged.
WINTER SHUT DOWN
• Drain water. 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 discon-
nected from both the unit and water supply so that it does not
freeze.
• Unplug motor and pump. When cooler is not used for extended
periods, unplug the motor and pump from inside cooler.
• Cover unit. To protect the life of the finish, a cover for the unit
is suggested in extended periods of non use.
By following the operating, installation, and maintenance sugges-
tions as outlined, you can get many years of efficient and satisfactory
service from your cooler. In the event additional information is de-
sired, your dealer will be more than glad to assist you in every
possible way.
