GENERAL INFORMATION
Applicable to all controller types
• If the unit appears to surge at times, check that strong wind drafts are not the cause. A strong
gust of wind may cause the fan to race momentarily as it is ‘wind assisted’.
• At times of high humidity, cooling performance is diminished. Operate the fan only.
• The cooling ability of a system is not only related to the efficiency of the unit design, but also to
the duct design and professional installation. Insulated ceilings will lower internal temperatures
significantly over non-insulated ceilings.
• During operation in Cool Mode, water discharges from the overflow pipe. This water has been
re-circulated through the pads many times. The evaporation process results in a build-up of
minerals and solids in the water. This water, if channelled onto the garden may be harmful to
some plants. It is not suitable for animal or human consumption. Test the water on plants in
small amounts before fully discharging into the garden.
• Never operate the system if the room vents have been closed off. This may cause overheating
and damage to the motor.
• At the time of initial start-up an odour may be detected. This odour is characteristic of Celdek
filter pads. It is neither harmful nor particularly unpleasant and will dissipate within 2-3 days.
The fan motor may also have an ‘electrical’ type smell for a short period as it heats up initially,
and residual varnish is ‘burnt off’ the motor’s surface.
• When the COOL mode commences, the tank is filled with water. This takes approximately 90
seconds, during which time the pump remains switched off. When the pump starts, water is
pumped up into the Celdek pads which quickly lowers the water level. For a short period of up to
one minute the water being pumped up into the filter pads exceeds the amount of fresh water
flowing into the base. The pump may make an intermittent “slurping” noise until the water level
is balanced. This is not harmful to the pump nor always audible, but please be aware of it
should you hear it.
PRE SEASON MAINTENANCE
We recommend an annual service, to keep your system in top operating condition.
The Service Centre telephone number together with the unit size and serial number are recorded on
the front and back of this guide. Electrical components to be maintained by qualified service people.
1. Isolate power at property’s main supply board. Disconnect
unit’s’ power plug from the mains supply. If cable damaged
have it replaced by qualified person.
2. Remove the lid.
3. If necessary, clean the base.
4. Close the water shut-off valve. Remove and clean shut-off
valve filter. Open shut-off valve.
6. Turn on the power. Operate the system in COOL Mode,
check that the drain valve closes and the tank fills with water.
7. Adjust the water level if necessary. Ideally this level should be
10mm below the overflow.
8. Check that the water is being evenly distributed over the pads
and that there are no obstructions in the water distributor,
located above the pads.
9. Replace the lid and secure it by firmly tightening the lid bolts.
Do not over-tighten.
