EVAPORATIVE COOLER OPERATION
INTRODUCTION
Congratulations on your purchase of a Rinnai Cooling system. For you to achieve the performance and efficiency
expected from your new cooler, please ensure the installer is a qualified trades person, that the installer has
commissioned the unit before you commence operating, and you take the time to read the contents of this manual�
In some Australian States it is mandatory that your cooler installation is issued with a certificate of compliance
to guarantee the installation workmanship� Please check with your installer or the local plumbing authority or
association� The Rinnai cooler is covered by the product warranty as outlined in this manual�
HOW DOES YOUR EVAPORATIVE COOLING WORK?
The amount of cooling available from any type of cooling system is dependent on the outside weather conditions�
Your evaporative cooler works best on hot, dry days� It is essential to provide the required amount of ventilation (for
your evaporative cooling system to function properly) by opening windows/doors whenever the cooler is operating�
Air is drawn in through the filter pads resulting in 100% fresh cool air entering the home. The movement of this
cooled air through your home will draw the heat out of the house, so be sure that doors or windows are open to
expel this heat to outside�
Whenever possible start the cooler early to prevent the build up of heat within the house, and on sultry or humid
days your cooler may work better with the fan ONLY running and the pump turned OFF� Stale air, cigarette smoke
and fumes can be quickly cleared and replaced with fresh air by turning the fan to manual mode�
BEFORE OPERATING YOUR EVAPORATIVE COOLER
Make sure enough window and/or door area is open for the unit to work correctly� The following table gives a guide
to the amount of open area required for each model in m
Model
I20
Three sliding windows or one door & two hinged windows
I10
Six hinged windows or four hinged windows and one sliding window
Door = 1.6m²
Average ventilation area provided by various openings when fully opened�
You can also choose to have these openings only halfway open, however note that the opening
will only provide half the amount of ventilation shown above and additional ventilation openings
would be required.
NOTE
To cool your whole house, you need windows and / or doors open throughout the house�
If you wish to concentrate your cooling to a select area, simply concentrate all the required ventilation in the
targeted area (see the following diagram on page 5)�
