ECONOMY MODE

Selecting the ECONOMY mode limits the
maximum available cooling or ventilation and
reduces the power used by up to 20%. The
ECONOMY function can be used in either
AUTO or MANUAL modes. To select this mode
press the button so that ECONOMY
appears on the display.

DRAIN MODE

Pressing the button opens the drain
valve in the cooler and empties the water in the
tank. This will leave the tank clean and dry and
turn the cooler off.

If the cooler has not been used for 3 days or 3
hours, depending on the DIP switch setting ­see page 6, the tank will automatically be
drained to ensure the system remains clean.

PRE-COOL MODE

Your remote control is designed to allow for the
saturation of the cooler’s cooling pads before
the fan is switched on. This function, referred
to as PRE-COOL mode, is enabled at DIP
switch D (refer to page 6). Once it is enabled
the cooler, when first switched on, will operate
as follows:

(1)...... If the pan is empty the drain system will

be closed. The pan will then be filled.

(2)...... The water inlet system allows water to

fill the pan, until the water level reaches the
lower pins of the water probe. After a 30
second delay, the pump will turn on and
saturate the cooling pads.

(3)...... After the pump has been running for 2

minutes the fan will start.

®

During this operation the word PRE-COOL will
be displayed on the remote control’s screen.

NOTE: PRE-COOL mode will not be activated
if VENT is selected on the remote control or
the cooler is used again shortly after having
been turned off.

WATER MANAGER

The Breezair remote control is fitted with the
WaterManager feature which automatically
monitors the quality of the water in the cooler.

The WaterManager drains the existing water
in the cooler to allow it to be replaced with
fresh water, only when it is needed. Therefore,
you may notice your cooler draining water
occasionally. How often the WaterManager
performs this operation depends upon the
quality of the water supply and the rate of
evaporation.

In areas of poor water quality, the
WaterManager will operate more often as it
tries to maintain the optimum water quality in
the cooler. This maximizes the cooling effect
and life of the cooling pads.

The remote control has a unique feature
attached to the WaterManager that allows
you to specify either high or low salinity
settings. The low salinity setting is used in
specific circumstances only. We recommend
talking with your dealer before adjusting this
setting.

The high salinity setting is designed to operate
the cooler at a maximum safe salinity level to
maintain a normal working life. It also results in
a minimum usage of water.

NOTE: High salinity outlet water should not be
used on salt sensitive grass or plants. It has a
high salt content.
The current WaterManager setting is
displayed by holding down the button and
pressing the button. The setting can be
changed by holding down the button and
pressing either the or button for
HI and LO respectively.
The factory default WaterManager setting is
HI. For areas operating with bore water, DIP
switch F should be switched to off (see page

6). This will disable the salinity measuring
circuit and simply drain water from the tank
every 65 minutes of operation.

POWER FAILURE RECOVERY

After a power disruption is restored, the cooler
will automatically restart within 10 minutes, if
the remote control has remained “ON” during
the power failure.

BATTERIES

If the batteries are installed when the display is
completely blank, the display will remain blank
for 5 seconds. After 5 seconds the display will
show “Id” for 1 second, then display the clock.
The remote control is now ready to use.
The remote control requires 3 AAA batteries.
The use of good quality alkaline batteries is
recommended. Under normal conditions a set
of batteries will operate for 18 months.
Do not use rechargeable batteries as their
voltage rating is too low for the remote control.
When the batteries are getting low on power,
BATTERY LOW is displayed on the screen (the
cooler may also switch off while the display
remains ON). This indicates that the batteries
have only a small amount of life remaining.

®

To change the batteries remove the cover from
the back of the remote control. Pull out the old
batteries and replace them all with the new
ones. Do not mix new batteries with old
batteries.
The remote control has 2 minutes of back-up
power to retain its memory while the batteries
are being changed.

DIP SWITCHES

There are 2 rows of DIP switches located
under the battery cover on the remote control.

WARNING: Do not alter DIP switches 1 to 8
on top row and 7 & 8 on bottom row as the
cooler will cease to work.

Definition of DIP switch positions (first 6 in
bottom row only) are as follows:

BOTTOM ROW
