How do they work?
Fresh outside air is drawn into the unit through a series of wet filter pads. This causes
evaporation to take place and the resulting air being blown through the duct work is filtered and cooled.
The resulting cool air is then dispersed into each room (to be cooled) through an outlet at a rate predetermined by your contractor at the time of sale. This rate of air is governed by the outlet size and the
duct layout. Adequate air flow is essential for optimum operation of evaporative cooling and it is
necessary to exhaust air via open windows or doors. It is advisable that each room that has an outlet
has the window slightly open. This allows the cool air to flow from the outlet across the room and out
via open windows. In some circumstances you can channel the air through the house by leaving a
door/window open at one end of the house, however you should consult your contractor for the best
way to do this.
Humidity
Evaporative coolers are particularly suited for dry regions. If outside air is particularly humid
then the best result from your cooling unit may be to run the unit on fan mode only (without operating
the water pump). This is done by pressing the fan only button and adjusting the fan speed to your
desired setting via the step button.
Electronic Control
The low voltage electronic control is designed to provide automatic and manual operation. It
provides the following features:
• Automatic Fan Speed Control in “COOL” Mode
• Manual Fan Speed Override for “COOL” Mode
• Fan Only Mode for Ventilation
• Timer Control for automatic switch off
Note that all commands use a delay of approximately ten seconds. For example, having
chosen a particular fan speed a change will not be noticeable for 10 seconds.

Operation
This section explains how to operate your Stadt Glacier evaporative cooler, and the functions
of each of the buttons featured on the evaporative cooling wall controller. Figure 1 shows the controller
for your evaporative cooler. It features four buttons which are used to control the operation of the unit,
and an array of lights which are used to display the operation of the unit.

Step Button
As explained throughout these instructions the “STEP” button is used to increment various
features such as the comfort level, fan speed or the time after which the unit will turn off.
On/Off Cool Button (Automatic Mode)
Press the button marked “ON/OFF COOL” once and the sequence of events listed below will
occur automatically.
1. A range of lights will appear on the display. The top light will indicate the current room
temperature. The lower flashing light will indicate your required comfort level.
2. Each press of the “STEP” button will change your required comfort level. For example at comfort
level two (2) the unit will cool less than comfort level one (1).
3. Your unit will not operate the fan immediately. Should the unit be fitted with a dump valve the unit
will fill the water sump. Should the unit not be fitted with a dump valve the sump will already be filled
with water.
4. Next, the pump will move water over the filter pads (pre-wetting) thus saturating your pads so the
first burst of air will be cool.
5. After the pre-wet cycle is finished the pump will continue to operate and the fan will come on
automatically. The fan will adjust its own speed according to the difference in temperature between
that inside your house and your selected comfort level.
6. As the room temperature nears the preset comfort level the fan of the unit will automatically slow
down and the number of lights will decrease, indicating the lowering temperature. As your house
temperature rises the fan speed will automatically increase to reduce the temperature to your
required comfort level or as close as possible. Note that the desired comfort level is not always
achievable as the humidity of the outside environment is variable.
7. To turn your unit off simply press the “ON/OFF COOL” button once again.
