Spring Start-Up - Marquis 3000 SM Guia De Inicio Rapido

• Connect water supply line.
Find the closest supply of wa-
ter. Use a saddle valve (Fig. 6)
to connect 1/4" tubing to the
cold water supply or use a
Sillcock and water valve con-
nected to an outside faucet
(Fig. 7). Place the nut and fer-
rule on the tubing and tighten
the nut until water tight. IM-
PORTANT: Do not connect the
water supply to any soft water
applications. Soft water will
cause corrosion and de-
crease the life of the cooler.
• Attach water line to float.
Attach the water supply line
to the float in the same man-
ner as above. The float may
be installed in either the cor-
ner post or bracket (Fig. 8).
• 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 ac-
complished by bending the
float rod.
• Adjust water amount. Your
cooler is equipped with a unique
water metering valve (Fig. 9). The amount of water deliv-
ered to the pads may be decreased by pressing the plastic
valve as the arrows indicate. If wa-
ter is splashing out of water troughs,
you may need to decrease the
amount of water delivery. 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 pul-
ley is adjusted to correct size to assure maximum air delivery
without damage to the motor. Be sure to follow these instruc-
tions 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 ten-
sion.
• 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
amperage 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 some-
one 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. Increas-
ing motor pulley diameter increases
amperage draw. Decreasing motor
pulley diameter decreases amperage
draw (see Fig. 10).
CAUTION:
Do not operate cooler with larger amper-
age 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 instruc-
tions 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 oil 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.
• Check belt tension. A 3 lb.
force should deflect the belt 3/
4 inches (see Fig. 11). Read-
just belt if needed.
• 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 absorbent
and efficient and will deliver substantially more cool air.
• Clean pump. Clean-
ing 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. 12. Clean the
pump and turn the impeller to ensure free operation. Re-
move 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 re-
place the spout and water delivery tube onto the pump outlet.
The pump has automatic reset thermal protection.
