General Information - Rinnai EHP32 Operation And Installation Manual

General information

Defrosting function
The heat pump has an inbuilt defrosting function. This requires power to prevent damage in freezing conditions.
DO NOT disconnect the power if there is a likelihood of freezing without draining the unit.
Draining and filling
Draining and filling of the complete system normally only occurs during installation or servicing and must be
carried out by an authorised person.
Draining water from the heat pump unit is necessary if the power will be shut off to the unit, and snow or frost
conditions are expected (it is not necessary to drain the storage tank). Arrange for an authorised person to carry
out this task.
Servicing
Rinnai has a maintenance/service and spare parts network with personnel who are fully trained and equipped
to give the best advice on your Rinnai appliance. If your system needs maintenance and/or servicing, please call
Rinnai (0800 746 624) from a land line and select option one for a service centre in your area.
For reliable operation Rinnai hot water systems should be serviced every two years. Regular maintenance and
servicing is not covered by the Rinnai warranty.
Do not attempt to carry out any work on your system other than that mentioned in the troubleshooting section.
If you have any faults or problems, contact your installer or call Rinnai.
