Unit Operation
It is essential for successful operation of the evaporative cooler that there be sufficient free air
openings in the room to be cooled – approximately 0.5m². Open doors and windows will
usually provide this as per the diagrams below.
Please Note:- It is important for good ventilation that doors or windows are not open on the
windward side of the house.
Bleed Off
The bleed off rate is factory preset and is not adjustable without direction of
the manufacturer. It is critical to the life of the product that the bleed off
function is not restricted in any way as this may void unit warranty and will
cause damage to your filters and cooler.
The function of the bleed off must be inspected by the owner on a regular
basis to ensure the bleed off continuously flows when the unit is operating
in “COOL” mode.
All evaporative coolers require water bleed-off to prevent build-up
of mineral deposits as the result of the evaporative cooling
process. This will maximize the life of the premium CELdek
® filter
pads and minimize mineral deposits inside the cooler. The bleed-
off function only operates in COOL mode (when the water pump
operates).
Should water supply contain high levels of total dissolved solids
(greater than 300 p.p.m.), increase the bleed rate. See page 14.
This bleed water can be used in gardens or diverted to drains
using standard garden hose and fittings from your local hardware
store.
Please Note: - Any additional pipe work fitted to the bleed off by the owner must slope away
from the unit in a down hill manner.
