MODEL TYPE

Congratulations for choosing a Raypak

Modulating type suitable for indoor or outdoor installation.

Raypak heaters utilise a finned copper tube heat exchanger resulting in a low water content and

reduced 'stand by' heat losses. Therefore a circulator pump of sufficient capacity to match the water

heater model must be installed in the system.

Raypak water heaters are fitted with Australian Gas Association approved components and are

designed to comply with AS 3814.

HOW HOT SHOULD THE WATER BE?

The required temperature of the water will have been determined by a qualified designer to suit the

application and set during commissioning. Under normal conditions the temperature should not require

adjustment.

For potable water applications requiring temperatures no greater than 75

operation should be installed. For temperatures above 75

with Modulating operation must be installed.

To meet the requirements of the National Plumbing Standard, for potable water applications, the

temperature of the stored water must not be below 60

If this water heater is installed as a booster as part of a commercial solar water heating system, to

maximise solar contribution it is recommended the thermostat is set at 60

temperatures are required.

HOTTER WATER INCREASES THE RISK OF SCALD INJURY.

This water heater can deliver water at temperatures which can cause scalding. Check the water

temperature before use, such as when entering a shower or filling a bath or basin, to ensure it is

suitable for the application and will not cause scald injury.

We recommend and it may also be required by regulations that an approved temperature limiting

device be fitted into the hot water pipe work to the ablution and public areas. This will keep the water

temperature below the maximum permitted by AS/NZS 3500.4 to these areas. The risk of scald injury

will be reduced and still allow hotter water to the kitchen, laundry and other areas requiring sanitising

temperatures.

TEMPERATURE ADJUSTMENT

This appliance is not intended to be adjusted by the user. Please consult the installer if you are

concerned with the temperature of the water.

This water heater is not intended to be operated, adjusted or tampered with by young

children or infirm persons. Young children should be supervised to ensure they do not

interfere with the water heater.

Removal of the access cover(s) will expose 240 V wiring. They must only be removed by an

authorised or service person.

This water heater is supplied with a thermostat, an over-temperature cut-out, pressure switch and

pressure relief valve. These devices must not be tampered with or removed. The water heater must

not be operated unless each of these devices is fitted and is in working order.

The warranty can become void if relief valves or other safety devices are tampered with or if the

installation is not in accordance with these instructions.
