OPERATION AND MAINTENANCE
Welcome to high e󰀩ciency year-round comfort.
Congratulations on your excellent choice and sound investment in a Rinnai Ducted Reverse Cycle Inverter Home
Comfort System. Please also take the time to read the contents of this Operating Manual, register your product
warranty and retain this document for future reference.
Your new Rinnai system represents both the latest in engineering developments and the culmination of many
years of experience by one of the most reputable manufacturers of home comfort systems.
Your new unit is among the most reliable home comfort products available today. To achieve the performance and
e󰀩ciency expected from your new system, please ensure the Installer is a qualied tradesperson, that the Installer
has commissioned the unit and instructed you on its operation.
To assure its dependability, learn about the operation of your system and the small amount of maintenance it takes
to keep it operating at its peak e󰀩ciency. With minimal care, your Rinnai system will provide you and your family
with satisfying home comfort - both now and for many years to come.
WARNING
Improper installation, adjustment, alteration, service, maintenance, or use, can cause explosion,
re, electric shock, or other conditions which may cause personal injury or property damage.
Refer to this document or and or other accompanying manuals.
For assistance or additional information consult Rinnai, a qualied installer or authorised service
agency. The qualied installer or agency should use only factory authorised components or
accessories if and when servicing this product.
To better protect your investment and to eliminate unnecessary service calls, please familiarise yourself with the
following:
• Your ducted system should never be operated without a clean lter properly installed. Plan to inspect the
lter periodically. A clogged lter will increase operating costs and shorten the life of the unit. Supply-air
and return-air registers (grilles) should not be blocked or obstructed. Restricted airow lessens the unit's
e󰀩ciency and life span.
• Outdoor (condenser / compressor) units must have unrestricted airow. Do not cover the unit, lean any thing
against it, or stand upon it. Do not allow grass clippings, leaves, or other debris to accumulate around or on
top of the unit. Maintain a minimum of 300mm clearance between the outdoor unit and tall grass, shrubs,
vines etc.
• Your Thermostat / Controller is the control centre for your system. Please familiarise yourself with its specic
operation, as the information following is of a general nature.
• Attempting to control the system by other means - for instance, switching the electrical supply power ON and
OFF, may cause damage to the unit.
• Thermostat ‘jiggling’ causes rapid-cycling, which is potentially dangerous to the compressor and may blow
the protective fuse or circuit breaker device at the mains power supply. Do not adjust the temperature on the
thermostat for any reason for at least ve (5) minutes after the compressor has shut o󰀨.
• You may nd that you can maintain greater personal comfort by running the FAN continuously. ‘Air pockets’
can form due to the structure of the building, placement of registers etc. These air pockets may create cool
or warm spots. Continuous FAN operation helps minimise any temperature di󰀨erences.
• Systems equipped with electronic air cleaners or humidiers accessories o󰀨er the added benet of having
the air continuously cleaned year round, and humidied during the winter season.
• Your system removes humidity from your home during the cooling season. The Indoor unit has a (primary)
condensate connected to your drainage system; but an overow (secondary) drain should also be installed.
If water is observed in the overow drain - it may be clogged, and your installer or Rinnai should be contacted
for inspection.
OPERATING YOUR SYSTEM
The operation of your systems is controlled by the indoor Thermostat / Controller. Simply adjust the Controller
to maintain the indoor temperature at the level you select, subject to it being within the design conditions of the
system. Typical settings are 24°C and 20°C for Cooling and Heating respectively.
The Rinnai Inverter System will automatically modulate the outdoor unit capacity in response to the demand of
the conditioned space, to help ensure rapid cool down or warm up times, as well as providing more constant
temperature control. Please refer to the Operating Instructions accompanying your Thermostat / Controller.
GENERAL USER GUIDE

Rinnai 10 DRCi AC_OM
COOLING CYCLE
When operating in the COOL mode, your system will run until the indoor temperature is lowered to the level you
have selected (within design conditions). On extremely hot days, your system will run for longer periods at a time
and have shorter ‘o󰀨’ periods than on moderate days.
The following typical conditions add extra heat and/or humidity to your home causing your system to work longer
to maintain comfortable conditions:
Entrance (external) doors are frequently opened &
closed.
More than the usual number of people.
Operating laundry appliances or running showers. Window furnishings open on sunny side of home.
More than the usual lights or electrical appliances
operating.
System operating at or outside the original system
design conditions as specied by your Installer
HEATING CYCLE
In HEAT mode, the system will provide warmth until the temperature is raised to the level you have selected.
The unit will operate for longer periods to maintain a comfortable environment on colder days and nights than on
moderate ones.
Defrost Cycle: When the system provides heating to your home and the outdoor temperature drops below 7.2°C,
moisture may begin to freeze on the surface of the outdoor coil. If allowed to build up, this ice would impede the
airow across the coil and reduce the amount of heat absorbed from the outside air. To maintain energy e󰀩cient
operation, your Rinnai Heat Pump has an automatic defrost cycle.
The defrost controls will automatically start when there is su󰀩cient ice to interfere with normal heating operation.
During defrost, the Indoor Fan will not be running. After the ice is melted, or after a maximum of 10 minutes in
defrost mode, the unit will automatically resume normal heating operation.
Do not be alarmed if steam or fog appears at the Outdoor Unit during the defrost cycle. Water vapour from the
melting ice may condense into a mist in the cold outdoor air.
ZONED SYSTEMS
Some home comfort systems are designed to operate on a zoned basis only – i.e. they are not designed to heat
and or cool the entire home or space at one time. Generally, a zoned system will be designed by your Installer
for your specic requirements. Your particular zoning conguration and the basis of design should be specied
and detailed by your Installer. With zoned systems, always observe the following:
• The Return Air grille(s) are generally in the ‘Common Zone’, and need to be part of the conditioned space
at all times.
• Close o󰀨 all doors to areas that are not being conditioned – i.e. e󰀨ectively isolate unconditioned spaces.
• Set your zoning conguration with your zone controls before starting your Rinnai system.
• Do not attempt to shut down more zones than the minimum as specied by your installer, as this may lead
to system shut down.
• Do not attempt to heat or cool more zones than the maximum specied by your installer as this will prevent
the system from being able to maintain design conditions. NOTE: The type of zoned system you have will
have been specied by your installer. This should include information on the total number of zones, the
minimum and maximum number recommended to operate at one time to maintain design conditions, and
the actual design conditions (Indoor Temperature Control settings at specied Outdoor Ambient conditions
for both Heating and Cooling).
PERFORMING ROUTINE MAINTENANCE
With proper maintenance and care, your Rinnai system will operate economically and dependably.
Maintenance can be accomplished easily by referring to the following general directions. However, before
performing maintenance, consider these important safety precautions:
• DISCONNECT ALL ELECTRICAL POWER TO HEAT PUMP BEFORE REMOVING ACCESS PANELS TO
PERFORM SERVICE OR MAINTENANCE – NOTE: THERE MAY BE MORE THAN ONE ELECTRICAL
ISOLATING SWITCH
• ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO MINIMISE SHARP EDGES IN THE CONSTRUCTION
OF YOUR UNIT, BE EXTREMELY CAREFUL WHEN HANDLING PARTS OR REACHING INTO THE UNIT.
GENERAL USER GUIDE

Rinnai 11 DRCi AC_OM
CHECKING THE AIR FILTER
• Filters are supplied and tted by your installer and are not part of the Rinnai system. A dirty air lter will cause
excessive strain on the compressor and fan blower motor. This can cause the compressor to overheat and
automatically shut down. In the extreme, the components will fail and will need to be replaced.
• To avoid ine󰀩cient or failed operation of your unit, CHECK THE FILTER AT LEAST EVERY 2 TO 4 WEEKS.
• Replace lters(s) when necessary, or clean them if they are the reusable type. Disposable lters should be
replaced by similar, new lters of the same grade and dimensions.
• Reusable (permanent) type lters should be washed in a solution of cold to tepid water and very mild
detergent, then rinsed and thoroughly dried. THE FILTER MUST BE COMPLETELY DRY BEFORE BEING
REPLACED.
• To avoid prolonged shutdown of your system while a lter is being cleaned, you may wish to have an extra
lter on hand. This would allow you to rotate between the two with minimal downtime for your comfort
system. Extra lters are available from your Installer or a Rinnai Spare Parts outlets.
• Should you have any questions about the removal and/or cleaning of you lter(s), please contact your
Installer for assistance.
• If grass clippings, leaves, shrubbery and debris are kept away from the Outdoor Unit, minimal care should
be su󰀩cient to keep the system functioning properly. However, if the outdoor coil becomes dirty, use a soft
brush or vacuum and soft brush attachment to clean the exterior surface. If dirt is trapped deep within the
coil, contact your Installer or Rinnai for service.
UNIT SUPPORT
• The indoor Fan Coil Unit (FCU) should be located in a position and in such a manner as specied in the
Installation Instructions. The FCU should be maintained at a position that ensures condensate drainage
from the unit. In an attic space, ideally the unit will be easily and safely accessible from the ceiling access
panel, have a suitable catwalk and platform, and if necessary a service light.
• The outdoor Condensing Unit (CDU) requires adequate support to ensure it is level. CDUs generate
condensate water in the heating mode; depending on local codes this may need to be discharged in a
prescribed manner.
NON–RINNAI FIELD SUPPLIED ACCESSORIES
Your home comfort system may include eld-supplied accessories that do not form part of this regular maintenance
cycle. These may include: ductwork, ttings, lters, grilles, zone motors, auxiliary heaters, third party controls and
other non-Rinnai supplied items.
These items may also require attention in accordance with the Original Equipment Manufacturer’s (OEM)
recommendations. Your installer can provide details in this regard, and should be consulted for any warranty or
service matters for these items. Whilst they are an integral part of your home comfort system, these non-Rinnai
items are not covered by your Rinnai Product Warranty.
Third party controls and zoning systems that interfere with the correct operation of your Rinnai Heat Pump system,
and any consequential damages to Rinnai equipment as a result of such incorrect operation, will not be covered
by Rinnai Warranty.

Rinnai 13 DRCi AC_OM
CLEANING THE AIR FILTER
The air lter requires inspection and cleaning at least every two weeks. Consult your installer for location of lters
on ducted systems.
NOTE
A dirty air lter will reduce the e󰀩ciency, e󰀨ectiveness and air quality of your system. Failure to
clean the lters regularly can also cause condensation to form and drip from the indoor unit when
operated in cooling mode during humid conditions.
CLEANING THE OUTDOOR UNIT
The outdoor (condensing) unit draws air into the unit and dissipates it away from the appliance. Periodic inspection
is required to ensure vegetation has not grown around the unit (plants, weeds etc.).
The cabinet should be kept clean and have the recommended clearances maintained. Ensure the discharge air is
free to dissipate and under no circumstances recirculates back into the unit.
Ensure there is no water build up (including from condensate drain) on or around the unit.
NOTE
Any unit repairs, maintenance and cleaning of the outdoor unit should be performed by an
authorised dealer or licensed service provider.
