Cooler Service Requirements; 3�1 Electrical Power Supply To The Cooler; 3�2 Water Supply To The Cooler - Rinnai I Series Installation Manual

3. COOLER SERVICE REQUIREMENTS

A qualified 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
IMPORTANT
electrical wiring is damaged, it MUST BE replaced by the manufacturer, its service
agents or an electrically qualified 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.
3.1 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 fixed
switched socket outlet located within the roof cavity, in close proximity to the dropper duct�
The fixed switched socket outlet should be wired back to the meter box on a dedicated power circuit.
3.2 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 insufficient
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 flushed before connecting it to the Cooler.
IMPORTANT
•
A registered licensed plumber MUST install the water supply piping and connection to the Cooler in accordance
with the local water supply regulations�
•
A bidirectional isolating gate valve on the water supply line shall be placed and secured in the Safety Tray
beside the Evaporator Module so that it does not dislodge�
This shall 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 bidirectional isolating gate 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 fittings or cause water hammer noise.
•
Water quality should be checked and filtration fitted where necessary e.g. tank or bore water.
•
The connection size to the Evaporator Module is 3/4" BSPF.
•
Once water is connected to the Evaporator Module the braided hose shall be secured within the safety tray by
the supplied cable tie�
