WARNINGS AND IMPORTANT INFORMATION
Rinnai 6 Evap AC IM
1.1 UNPACKING THE COOLER
The unit is supplied on a pallet and enclosed with protective packaging.
To unpack:
•
Carefully remove the outer packaging and any retaining brackets/straps that secure the cooler to the pallet.
Rinnai coolers MUST BE installed in accordance with these instructions and related regulations, codes, standards,
and authorities. These include but may not be limited to:
•
AS 3500.2 - Plumbing & Drainage
•
AS 4254 - Ductwork for air-handling systems in buildings
•
Local Building Regulations
•
HB 276 - A Guide to Good Practice
•
Environment Authorities
•
Local Plumbing and Electricity Authorities
•
Building Code of Australia (BCA)
1.2 UNLOADING THE COOLER
When lifting the cooler onto the roof, ensure the lifting equipment is in good operating condition and capable of
lifting the total weight. Be sure there is a clear area to place the cooler down, which is within reach of the lifting
equipment.
1.3 COOLER POSITIONING
The Cooler shall be installed in a position that allows adequate and safe access for service, and enables only fresh
outside air to be drawn into the unit. The cost of any equipment and additional labour involved in accessing cooler
installations will not be accepted by Rinnai.
Avoid positioning the cooler near any source of smoke, dust or objectionable fumes so that only fresh outside air
will be drawn into it. Coolers should not be sited close to the windows or bedrooms of neighbouring houses.
The cooler shall not be installed within a 5m (6m in W.A.) radius of a sanitary vent, 1.5m radius from a gas
appliance ue terminal and 3m horizontal radius from a wood stove ue terminal.
1.4 WEATHER PROOFING
All ductwork, electrical cables and water pipes MUST BE ashed and sealed, to prevent water entry into the
building. Exposed ductwork MUST BE weatherproofed and coated with reective aluminium paint.
1.5 INSULATION
It is important that ducting should be well insulated. It is mandatory under some building codes to install insulated,
re rated ducting on Evaporative Cooling systems. Check with your local authority.
1.6 INSTALLING DUCTWORK
The duct system should be designed and installed in accordance with the following:
•
These installation instructions.
•
Standard engineering practices.
•
Rinnai Sizing Guide and Installation Guidelines.
1.7 SYSTEM
The installation unit MUST comply with all laws, regulations and industry standards applicable in the state or
territory in which the products are installed.
1. GENERAL GUIDELINES
Rinnai 7 Evap AC IM
IMPORTANT
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 insufcient
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 Rinnai Networker and Manual Wall Control 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 effectively, 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 difference on an external wall can affect 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 affecting 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 affected 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 0.75mm2 in cross section and less than 100m in length.

2. COOLER SERVICE REQUIREMENTS
Rinnai 8 Evap AC IM
3.1 BENDS AND ELBOWS
•
Where square ducting elbows are to be used, install turning vanes within the elbow to aid airow.
•
Use unrestricted ductwork with smooth changes of duct cross section.
•
Bends in ducting should have a large radius and branches should have shallow angles.
3.2 DAMPERS
Dampers may be required to balance the air distribution of the duct system.
3.3 FIX AND SEAL THE ROOF FLASHING
The roof ashing MUST BE xed and sealed to the dropper duct to prevent water entry into the building. Ensure
that the screws or rivets DO NOT protrude into the dropper duct more than 8mm.
Installations where the Cooler is more than 4m downstream from the roof peak should be tted with an additional
water-diverting channel on the dropper duct high side, that extends beyond the dropper duct sides by at least
50mm (see diagram below).
NOTE
This diagram is for Rinnai C Series Models.
3.4 DROPPER DUCT INSTALLATION GUIDELINES
•
The dropper duct on which the Cooler is mounted MUST BE properly secured to the roof structure or timbers.
•
Ensure the dropper duct does not contact the ceiling joists or other structural members that can transmit
vibration.
•
If possible, the dropper duct should be positioned to the rear or on the service side of the home.
•
It should also be as far down the roof as practicable.
•
Rinnai recommend installing a diffuser or cone in the base of the dropper box. This will assist distributing the
airow evenly into the duct system and can also reduce noise levels.
