Performing Routine Maintenance - Rinnai Pro Series Operation Manual

Performing routine maintenance

Central heating and cooling systems, like cars, require regular maintenance and
servicing. For reliable operation Rinnai heat pumps / air conditioners should be
serviced annually by a licensed tradesperson.
Before cleaning or maintenance turn off your system and disconnect the power supply.
Outdoor unit
The outdoor (condensing) unit draws air into the unit and dissipates it away. Periodic inspection is
required to ensure vegetation has not grown around the unit. If grass clippings, leaves, shrubbery
and debris are kept away from the outdoor unit, minimal care should be sufficient to keep the
system functioning properly. Maintain a 300 mm clearance between the outdoor unit and tall grass,
shrubs, vines etc.
If the outdoor coil becomes dirty, use a soft brush or vacuum with a soft brush attachment to clean
the exterior surface. If dirt is trapped deep within the coil, contact your installer or Rinnai for service.
Condensate
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—contact your
installer or Rinnai for advice. The condensate needs to be properly drained to waste water.
General maintenance for prolonged periods of non-use
If you plan on not using your ducted system for an extended period of time:
• Turn on FAN function until the system drys out
• Turn OFF the unit and disconnect the power
• Turn off the wall controller
Maintenance - pre-season inspection
• Get the filters cleaned
• Check for damaged wires
• Check for leaks
• Check nothing is blocking all air inlets and outlets of the indoor and outdoor units
Service technician - easy clean and maintenance
Service technicians are able to get easy access to the filter(s). Filters, depending on the model,
can be pulled out from the left, right, or bottom for easy cleaning.
Maintenance is also easy with top or bottom access to the header unit, and there is a large space
to the side for access to connections, wiring, and the PCB.
