WALL CONTROL FUNCTIONS

TWO SPEED AND VARIABLE SPEED AIR
CONDITIONERS.
Your evaporative air conditioner has control
switches to provide for the benefits of fresh
air ventilation and cooling at high and low air
flows. There are two types of control switches
available: Two Speed and Variable Speed.
Your control panel offers independent control
for the fan and cooling functions.

TO START THE AIR CONDITIONER

1. Switch the COOL control on.
2. Turn on the AIR (fan) control and using
The SPEED switch (HI/LO switch or Variable
knob), select the fan speed you require.
When ventilation only is required (air flow with
no cooling) turn the COOL switch off, and
select the fan speed to provide the air flow you
require.

TO STOP THE AIR CONDITIONER

Switch the COOL control off, then switch the
AIR control off.

USING YOUR AIR CONDITIONER

Evaporative air conditioners provide very
effective cooling by drawing outside air through
filter pads saturated with water. This water
washes the air and cools it by the process of
evaporation. There are a number of operating
techniques and circumstances of which you
should be aware to get the best performance
from your evaporative air conditioner.
To provide effective cooling or ventilation, the
air conditioner must be operated with sufficient
openings to exhaust the air. For example:
ILL771-A
windows, doors or ducts. The location of the
opening(s) will determine the pattern of cool air
flow. The following are the minimum opening
sizes required in square metres:

ILL2141A
In light wind conditions more cooling can be
obtained by opening additional windows and
doors. In windy conditions close openings
facing the wind.
Generally, openings opposite the supply vents
are best. Some experimentation will soon
show the arrangement most suited to your
requirements. For a multiple outlet system, this
is generally 1 (one) window opened 100 to 150
mm per outlet.
For a short time, when operating with new
filter pads, you may detect an odour like "wet
timber". This is the filter material becoming
conditioned to use.
In many areas the water supply is quite hard.
When this water is evaporated through the
filter pads, the hardness is deposited as a
scale on the pad. To reduce this scale build-
up and to retain efficient filter pads a small
amount of water is bled from the system.
The continuous drain of small amounts of
water ensures that fresh water is added to
dilute any build-up of scale or salts. The bleed
rate for your air conditioner will depend on
local operating conditions and will be adjusted
during installation.
