6 Pro-series Ducted Evaporative Cooler Use and Care Manual
Changing Cooler Pads
CAUTION:
Disconnect all electrical power to the cooler before
attempting to install, open, or service your cooler. If the cooler is
thermostatically controlled, the thermostat is not to be used as
the power supply disconnect, as it may reset and start the unit
unexpectedly.
The condition of your cooler pads should be checked at least once a year;
at the beginning of the season is best. However, your pads may need to be
checked more frequently, depending on local air and water conditions.
Clean or replace pads as follows:
1. Disconnect power from unit.
2. Remove pads from wet section cabinet as follows:
a. Remove inlet louver panel, top pan, water distributor cover and
tube assembly from cabinet.
b. Remove pads by tilting slightly forward and carefully lifting up
and out. If passages are clogged or pad is dirty, hose off inlet
face of pad. Light,
gentle
brushing of the inlet edges of the pad
with a stiff bristle brush (do not use a wire brush) will not harm the
pad and will remove more stubborn scaling..
c. If necessary, replace with new pads, available from your dealer.
Aspen, expanded paper or other types of evaporative cooling
pads will not work and will void your warranty.
3. Using a mild detergent, wash dirt and scale from the inside of the
wet section cabinet. Wire brushing is not recommended. If finish is
damaged or rusting is noted, repair as noted in the “Touch-Up”
section. Rinse with fresh water.
4. Reinstall pads, making sure they are positioned correctly (painted
stripe on pad placed to the bottom, facing outside).
5. Reinstall water distributor cover and tube assembly, top pan and
inlet louver panel.
REPLACEMENT PARTS
When ordering replacement parts, always refer to the serial and model
number of your cooler. Use the part numbers listed in the accompanying
parts list, as illustrated in the diagrams for your model.
Winter Shut Down:
-
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 disconnected from both the cooler and the water
supply so it does not freeze.
- Disconnect
power from cooler during extended periods of non-use.
