Rinnai Australia - 3 - HOTFLO Electric Storage Water Heater Operating/Installation Manual

REGULAR CARE

Over flow tray and drain

The overflow tray and drain (if fitted) should be periodically checked to ensure there are no blockages.

Pressure and Temperature Relief (PTR) Valve

This valve is located near the top of the water heater and is essential for safe operation. It is normal for the valve

to release a small quantity of water through the drain line during heating. However, continuous leakage of water

from the valve and its drain line may indicate a problem with the water heater.

Expansion Control Valve (ECV) if fitted

Operate the easing lever on the expansion control valve once every six months. It is very important you raise and

lower the lever gently.

• Never block the outlet of the PTR valve or its drain line for

any reason. The easing gear must be operated at least once

every six months or more frequently in areas with a high

incidence of water deposits. It is very important you raise

and lower the easing gear gently.

• Failure to do this may result in the water heater cylinder

failing or under certain circumstances, exploding.

• If the valve does not discharge water when the easing gear

lever is lifted, or does not seal again when the easing gear

is closed, attendance by an authorised person must be

arranged without delay. The PTR valve is not serviceable.
