Brivis 7 Evap AC IM
2. COOLER SERVICE REQUIREMENTS
A qualied electrician MUST install the 240 Volt wiring according to local regulations.
Switch OFF the power and unplug the Cooler before touching any wiring. If any
electrical wiring is damaged, it MUST BE replaced by the manufacturer, its service
agents or an electrically qualied technician, in order to avoid a hazard.
The electricity supply MUST BE 240 Volt / 50 Hertz, and from an authorised power
supplier. Generators should NEVER be used, as their output may be incompatible
with or damage the Cooler’s electronic control system.
2.1 ELECTRICAL POWER SUPPLY TO THE COOLER
The Cooler is pre-wired with a 3-pin plug and lead, and should be plugged into a standard 10 Amp - 240 Volt xed
switched socket outlet located within the roof cavity, in close proximity to the dropper duct. The xed switched
socket outlet should be wired back to the meter box on a dedicated power circuit�
2.2 WATER SUPPLY TO THE COOLER
The Cooler’s water system is designed to operate with a water supply pressure between 300 kPa and 1000 kPa�
If the supply pressure is excessive, a pressure-reducing regulator will be required. If the pressure is insucient
the Cooler’s operation will be compromised� In areas subject to water pipes freezing, provision MUST BE made
to drain water piping to prevent damage to the Cooler�
•
Ensure the supply piping has been ushed before connecting it to the Cooler.
•
A registered licensed plumber MUST install the water supply piping and connection to the Cooler in accordance
with the local water supply regulations�
•
An isolating valve on the supply pipe MUST be placed external and adjacent to the unit, not inside the ceiling�
This MUST BE provided to facilitate isolation of the water or to disconnect the water supply piping when
servicing�
•
Non-return isolating valves on the water supply are not recommended as they may cause damage or lock up the
Cooler’s inlet mechanism where high lock-up pressures or freezing water in pipes may occur�
•
For the owner’s convenience, an additional isolating valve may be provided at ground level to isolate the water
supply�
•
The water supply pipe MUST BE supported and secured so as not to place strain on the Cooler’s water
connection ttings or cause water hammer noise.
•
Water quality should be checked and ltration tted where necessary e.g. tank or bore water.
•
DO NOT remove water supply line, (braided hose) from rear of cooler�
2.3 INSTALLING THE WALL CONTROL
The Brivis Networker, Manual and Programmable Wall Controls are part of a sophisticated control system�
Controllers with Auto mode constantly monitor the temperature inside the house, switching the Cooler ON and
OFF to maintain the target comfort level selected. To do this eectively, the wall control MUST BE positioned
correctly:
•
Install the wall control within the area being cooled: It is important that the Wall Control is placed in a
position that will provide the most accurate reading of the temperature within the area being cooled�
•
Attach to an internal wall: The temperature dierence on an external wall can aect the reading, so always
mount the wall control on an internal wall� Also keep the hole in the wall for your wiring as small as possible to
prevent draughts from within the wall cavity aecting the temperature sensing.
•
Get the height right: The Wall Control should be approximately 1500mm above oor level.
•
Avoid hot spots: Keep it as far away as possible from heat sources, e�g� above electrical equipment, direct
sunlight and walls backing onto wall-ovens and stoves�
•
Avoid cold spots: Ensure that the Wall Control is not aected by draughts coming through doorways, windows
and stairwells, and is not placed too close to cooling outlets�
•
Avoid dead spots: Don’t site it in areas with no or little circulation, e�g� behind doors, in corners or alcoves�
•
Interference from other electrical connections: Ensure the thermostat and wiring are kept away from other
electrical, data and antenna cables�
•
Use the right cable: Ensure the cable is 0�75mm
2
in cross section and less than 100m in length�
