INSTALLING THE CONTROLLER CABLE
Connect one end of the MagIQtouch Controller cable (with
ferrite suppressor) to the cooler electronics box.
Feed looped end of the controller cable (A) through the “wedge
shaped” knockout and into the dropper.
Important!
Ensure cables do not interfere with the
weatherdamper.
Note!
It is important to route both cables out through the
dropper grommet before fitting ductwork.
Installation of the cooler must conform to local electrical rules,
regulations and standards.
Important!
It is a requirement of Seeley International that
all Breezair coolers be connected to a dedicated circuit to
the distribution board, with a separate circuit breaker and
incorporate a separate isolation switch in accordance with the
local wiring rules.
A 10A socket outlet within one metre of the dropper’s cable exit
hole is required.
The following specifications for the cooler electrical supply are
required:
240V / 50 Hz Single Phase
WARNING!
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly qualified
ELECTRICAL REQUIREMENTS
Installation of the cooler water supply must conform to
local plumbing rules, regulations and standards including
AS/NZS 3500.1
The following specifications for the cooler water
supply are required:
Water Connection
½” BSP
Min Water Pressure
100 kPa (15 psi)
Max Water Pressure
800 kPa (115 psi)
Min Water Flow
8 litres / min
Max Water Temperature
40°C
Important!
If the water pressure exceeds maximum
specification then a pressure reducing valve is required
and must be supplied and fitted by the installer.
Harmony & Horizon
For Coolers with the inlet solenoid valve fitted, the water
connection is a 1/2” BSP compression fitting on the end of a
flexible hose. This can fit directly onto the water pipe or be
screwed directly onto the manual water shut-off valve. Always
ensure that the water pipe connection does not place sideways
strain onto the float valve.
Homemaker
A permanent water supply is required to be connected to the float
valve. The water connection point is located on the underside
of the cooler. The water connection fitting is a 1/2” BSP male
adaptor suitable for a compression fitting. Do not fit the manual
water shut-off valve directly onto the plastic nipple. You must
install a manual 1/4 turn ball type shut off valve (do not use a
stop cock) in the water supply line adjacent to the cooler, subject
to local plumbing regulations. This allows the water supply to be
isolated whenever work needs to be done on the cooler.
Important!
In areas subject to freezing, the water supply line
to the cooler requires a drain down facility at the lowest point in
the water supply pipe.
Important!
Flush the water pipe to remove any swarf before
final fitting. Swarf can lodge in the solenoid and float valve,
preventing them from functioning correctly.
