BREEZAIR EXQ/EZQ/EXS EVAPORATIVE COOLERS INSTALLATION MANUAL
|
9
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 all pole disconnection 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:
220V, 220-240V, 230V, 240V / 50Hz, 60Hz Single Phase
WARNING!
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or a similarly qualified
person in order to avoid a hazard.
ELECTRICAL REQUIREMENTS
Installation of the cooler water supply must conform to
local plumbing rules, regulations and standards.
The following specifications for the cooler water
supply are required:
Water Connection
½
”
BSP
Min Water Pressure
100kPa (15psi)
Max Water Pressure
800kPa (115psi)
Min Water Flow
8 liters/min (2.1 gallons/min)
Max Water Temperature
40°C (104°F)
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.
WATER REQUIREMENTS
MULTIPLE COOLER INSTALLATIONS WITH
EXTERNAL AIR SENSOR
Ensure all cooler electronics dipswitches are set to ‘OFF’ except
for the last cooler in series. The last cooler dipswitch should be
switched to ‘ON’ to ensure communication reliability.
Only 1 x External Air Sensor will operate in a multi-cooler
installation. If multiple External Air Sensors are fitted disconnect
the External Air Sensor plug from each of the cooler electronics’
except for the last cooler in the series.
