Section 4 - OPERATION & Section 5 - MAINTENANCE
Location & Orientation
When choosing a location for
the cooler, maintain a safe
distance from flame or other
possible sources of ignition and
ensure compliance with local
regulations.
Using your Cooler
To operate effectively, evaporative
air coolers always need to function
on 100% fresh outside air. Always
locate the cooler where it will
receive a plentiful supply of fresh
air and not in an area where it
may be starved for air or where the
air is polluted.
Open or provide exhaust outlets in
the building you are cooling. Such
outlets may be provided by the
opening of doors and/or windows.
Locate the cooler close to an
opening but blowing into an area to
be cooled.
If the design of your building does
not allow such easy exhaust
provisions, then you must install
mechanical ventilation, such as an
exhaust fan which can extract
approximately 80% of the air that
the cooler is discharging.
Generally, the higher the ambient
relative humidity, the higher the air
quantity required from the cooler.
You should therefore control the
speed of your cooler accordingly.
On very dry days the cooler will
give maximum cooling and this will
decrease as the humidity
increases.
Never allow cooler air to be
discharged into a closed space,
it must always be allowed to
exhaust out.
You can keep your building cool for
about 1/4 of the cost of refrigerated
air conditioning.
The outlet grille for your Convair
MobileMax has four way adjustable
direction louvres.
Keep louvres as wide open as
possible for maxiumum effect.
Cooler Operating
Instructions
• Fill the tank, or if connected via a
hose, turn on the water supply at
the source.
• The Cooler's tank may be filled
by bucket, hand-held hose or
automatically via the float valve by
connecting a high pressure hose.
• For extended pad life and
effective cooling your Convair
MobileMax needs a continuous
supply of good quality water.
• Turn on the electrical power at
the source.
• Wait ten (10) minutes for the
water to fill the cooler pan/tank.
• Watch the water level indicator,
do not overfill the tank at any time.
• Using the switch on the front of
the cooler, turn on the pump only
to properly wet the pads. Run for
five (5) minutes.
• Select LOW fan speed at the fan
switch.
• At times when the outside
humidity is high, you may feel
more comfortable by turning off the
pump and running the fan only.
This will not cause any damage
to the pump. High speed - no
pump for high humidity, low
speed - pump on low humidity.
• Ensure there are exhaust
openings in the building.
Section 5 Maintenance
Allow for adequate access around
the cooler when performing
maintenance.
Provision must be made for
access to electricity and water
supplies.
Never force parts together, all
parts are designed to fit together
easily without undue force.
Pre-Season Maintenance
• Turn off the electric power
supply.
• Turn off the water supply.
• Remove the pad frames.
• Fit new pads if necessary.The
frequency of replacement depends
on the condition of the
environment and the water.
The pads supplied have been
selected to give the highest
possible cooling performance. Do
not use alternatives. The
manufacturer is not responsible
for the performance of the cooler
when alternative pads are used.
When replacing the pads, ensure
the material is evenly distributed
across the entire frame to a
thickness of about 2". Regular
"thin" pads will reduce the cooling
efficiency of the cooler. Particular
attention must be given to the
corners of the pad frames. Avoid
gaps and holes in the pad.
Daily Maintenance
• Drain the water from the tank
and refill with fresh water
