Rinnai Pro Series Installation Manual page 5

R32 refrigerant
This appliance uses R32 (difluromethane) refrigerant, which is a flammable gas class A2L
according to AS 5149.1 and MUST BE handled by a refrigerant mechanic with the appropriate
refrigerant handling licence.
Warning risk of fire / flammable material. If the refrigerant is leaked, together with an ignition
source, there is a possibility of ignition.
Minimum room sizes
When flammable refrigerants are used the appliance shall be located in a well ventilated area
where the room size corresponds to the room area as specified for operation, refer table below.
Please ensure that these minimum room sizes are adhered to for standard installations (up to 15 m
pipe length). If larger refrigerant charges than standard are used the installer must consult
AS/NZS 60335.2.40 to determine the safe minimum floor area for the installation. Minimum room
sizes are calculated on the base charge provided with the outdoor unit.

Location and positioning
Installation must be in a position that can support the unit's weight. If the chosen location cannot
support the weight of the unit, or the installation is not done properly, the unit may drop and cause
serious injury or damage.
The installer must install drainage piping according to the installation instructions. Improper
drainage may cause water damage to your home or property.
• Do not install the unit in location that may be exposed to combustible gas leaks. If combustible
gas accumulates around the unit, it may cause a fire.
• Do not install the outdoor unit where noise may cause a nuisance, such as near bedrooms or
neighbouring properties.
• Where possible do not install the outdoor unit where it will be exposed to sea wind and salt
spray, this will significantly reduce the durability of the unit.
Flexible demand (DRED - Demand Response Enabling Device)
Rinnai ducted R32 models are compatible with air conditioning demand response programs, which
allow energy providers to manage peak demand periods by reducing the power consumption of the
compressor. This can be enabled by purchasing a separate component.
Mode Mode description
DR mode 1 Compressor off
DR mode 2 The air conditioner continues to cool or heat during demand response activation, but the total
electrical energy (kWh) consumed by the air conditioner in a half hour period is not more than 50%
of the total electrical energy that would be consumed in a half hour period during normal operation—
under the same temperature and humidity conditions (and the same user settings).
DR mode 3 The air conditioner continues to cool or heat during demand response activation, but the total
electrical energy (kWh) consumed by the air conditioner in a half hour period is not more than 75%
of the total electrical energy that would be consumed in a half hour period during normal operation—
under the same temperature and humidity conditions (and the same user settings).
For more information on the wired connection to the DR board refer to the supplementary
information available online or contact Rinnai for further information.
