PLACEMENT OF THE UNIT
There are three primary considerations when deciding
where to place this unit:
1.
Fresh Air Supply – The inlet side of the unit
(pad side) must be placed so as to ensure that a
smooth, uninterrupted supply of fresh air is available.
2. Air Pattern – The cool air discharged from
(fan side) the unit should have a clear area in which
to circulate, being as free of obstructions as
possible.
3. Ventilation (Exhaust) – There should be a defined
place in which the air from unit can be exhausted
from the area being cooled. This is to prevent the unit
from recirculating air that has already been through
the cooling process.
A primary consideration when actually deciding where
to place the unit is the direction of the airflow. The unit
creates a fan-shaped air pattern that circulates air over
a large area. This pattern may be disturbed or broken
up by obstacles such as shelves, workbenches, etc. It is
important to insure that a clean, unbroken path for the air
from the unit is provided to the maximum extent possible.
You may want to raise the unit above any low
obstructions in order to increase the overall coverage.
When raising the height, ensure that the platform
constructed for holding the unit is stable, well constructed
and will not allow the unit to tip over. The unit must be
level and in the upright position, with casters locked.
When supporting with a platform allow for the full weight
of a functioning unit by including the weight of the water
both in the sump tank and the added weight of the water
saturated cooling pads. The total weight could be in
excess of 500 lbs. (227 kg.).
When the unit is placed near a wall or other obstruction,
it is recommended that a distance of at least 3 feet from
any wall or obstruction to the face of the cooling pads.
This allows the unrestricted flow of warm air to the cooling
pad side of the unit. If multiple units are used near
each other, be sure to aim the unit so that the air flows
compliment each other. Opposition will negate the
airflow and allow an area of dead air to accumulate
between units.

OPERATION
FILLING WITH WATER
Once the unit is connected to a water supply, turn on the
supply valve that fills the sump tank with water. Once the
sump tank is full, the float valve will shut off the supply
flow. (50 psi max. inlet water pressure.)
STARTING THE PUMP AND ADJUSTING
THE WATER FLOW
CAUTION! Do not run pump when sump is dry.
1. Once the sump tank is full, move the pump switch to
the ON position to turn on the pump.
When first turning on the pump, the level in the sump
will drop suddenly and restart the flow of supply
water. This is a normal condition, as the cooling pads
require a large amount of water for proper wetting.
When the unit is new, the new pads will require an
initial 'breaking-in' period. This period is required for
the pads to begin readily absorbing water. It may
require up to a week to achieve maximum efficiency.
2. It is important that the spray bar is properly adjusted
when first starting the water flow in the unit. To
increase or decrease the flow use the spray bar
adjustment valve on the side of the unit.
NOTE: Evaporative media should appear wet.
STARTING THE FAN
NOTE: Cooling pads must be installed and wet,
and caster brakes must be engaged.
Start the fan by turning the fan switch to desired speed.
Adjust the speed slowly allowing the fan to obtain its full
speed at the low speed before going to meidum and
high.
Pads should appear wet; however, cascading amounts
of water can actually reduce cooling efficiency. Proper
adjustment will prevent problems and increase cooling
capacity.
When turning the fan off at the end of the day or
week, the pump should be turned off about 15 minutes
before the fan to allow the cooling pads to dry. This will
increase the life fo the pads.
