GENERAL USER GUIDE

OPERATION AND MAINTENANCE

Welcome to high efficiency year-round comfort.
Congratulations on your excellent choice and sound investment in a Heat Pump 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
efficiency expected from your new system, please ensure the Installer is a qualified 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 efficiency. With minimal care, your Rinnai system will provide you and your family
with satisfying home comfort - both now and for many years to come�
Improper installation, adjustment, alteration, service, maintenance, or use, can cause explosion,
fire, electric shock, or other conditions which may cause personal injury or property damage.
Refer to this document or and or other accompanying manuals.
WARNING
For assistance or additional information consult Rinnai, a qualified installer or authorised service
agency. The qualified 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 filter properly installed. Plan to inspect the
filter periodically. A clogged filter 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 airflow lessens the unit's
efficiency and life span.
•
Outdoor (condenser / compressor) units must have unrestricted airflow. 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 specific
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 five (5) minutes after the compressor has shut off.
•
You may find 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 differences.
•
Systems equipped with electronic air cleaners or humidifiers accessories offer the added benefit of having
the air continuously cleaned year round, and humidified 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 overflow (secondary) drain should also be installed.
If water is observed in the overflow 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�
