Congratulations on the purchase of your Rinnai appliance. We trust you will have many years of comfort and enjoyment from your appliance. BEFORE USING THIS APPLIANCE Before proceeding with the operation or installation read this manual thoroughly and gain a full IMPORTANT understanding of the appliance, to ensure safe and correct use.
For safety and warranty purposes, appliances that may be damaged or incorrect MUST NOT be installed or operated under any circumstances. Installation of damaged or incorrect appliances may contravene local government regulations. Rinnai disclaims any liability or responsibility whatsoever in relation to the installation or operation of damaged or incorrect appliances.
As a general good practice it is better to keep the compressor upright as much as possible to avoid any risks. Returning the Rinnai Electric Heat Pump to a vertical position will not allow the oil to properly flow back into the compressor motor.
NEVER…. Leave a toddler in the care of another child. They may not understand the need to have the water temperature set at a safe level. Rinnai Commercial Heat Pump OIM...
We recommend and it may also be required by regulations that an approved temperature limiting device be fitted into the hot water pipework to the bathroom and ensuite when this water heater is installed. This will reduce the risk of scald injury and still allow hotter water to the kitchen and laundry. Rinnai Commercial Heat Pump OIM...
If the valve leaks continuously, try easing the valve gear for a few seconds. This may dislodge any foreign matter and alleviate the problem. If this does not alleviate the problem contact Rinnai. Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.
Operate the easing gear of the PTR and the ECV if fitted as described in the section ‘Safety Devices’ on page 9. The overflow tray (supplied by installer) and drain underneath the storage cylinder (if fitted) should be periodically checked to ensure there are no blockages. Rinnai Commercial Heat Pump OIM...
