Features

•Mains pressure storage water heater ensures stable hot water supply.

•Various tank capacities available –allow simultaneous multi point hot water

usage.

•The adjustable thermostat automatically controls the electricity supply to the

heating unit so constant temperature is maintained.

•Safety devices such as over temperature cut out and Temperature and

Pressure Relief (TP&R) vale are standard features.

•The temperature is preset at 65°C for reasons of safety and economy, but can

be field reset if necessary.

•The life span of the tank is greatly extended by our exclusive “Rheemglas”

vitreous enamel lining and sacrificial anode rod, ensuring years of trouble free

performance.

•Thick Polyurethane foam free of CFC enables the water heater to be more

energy efficient by retaining heat and thus reduce operating cost.

•Heater jacket is protected by colorbond –a thick gauge precoated steel having

exceptional strength and corrosion resistance.

Safety

•The water heater must have provision for drainage in the event that the water

heater leaks or connection pipes break.

•The water heater uses 220-240V/50Hz AC x single phase.

•Power supply cable must be sized to safely carry maximum current draw.

•Ensure that the electrical connections are undertaken by a qualified

electrician complying to Local Code of Practice.

•Power must not be turned on until the water heater is filled with water. Open

all hot water taps/faucets to release trapped air until only water is discharged.

•Temperature over 50°C may cause scalding. Please mix cold water with hot

water to obtain the right bathing temperature.

•Please operate the T&PR valve manually at least once every 6 months to

remove lime deposits and verify that the drain pipe from the valve is not

blocked.

•Power must be turned off before any service and maintenance work is

undertaken by a qualified technician.

•For replacement of parts, please use original parts from manufacturer. Use

of non-approved parts will result in a void of warranty for the heater.

•Water may drip from the discharge pipe of the TPR valve during normal

expansion. The discharge pipe should be left open to the atmosphere

preferably 150 mm above the nearest floor trap. On no accounts must the

drain pipe be plugged.

Installation and Connection

Choose where to install

▪The water heater must be installed indoor.

▪The wall must be strong enough to hold a heater using brackets and raw

plugs provided.

▪The heater is to be installed as near to the point of use as possible.

▪Ensure that sufficient space is available for servicing..

▪There must be a floor trap near installation point.

▪Water heater/electric plug/electric leakage protector should be protected

from splashing water.

Installation

▪Fasten bracket on the upper holes in the back of Water Heater with M10

bolts and washer.

▪Fasten plastic spacer on the lower holes in the back of Water Heater with

M10 screws and washer.

▪Locate the drilling position for expansion bolts on the wall, as shown in

diagram2. The four holes must be in the same horizontal line.

▪Drill holes on the wall, and then insert into the holes the M12x100

expansion bolts with nut. Hung up the heater on the wall and fasten the

Bracket with nut.

Connection –Plumbing

▪Pipe Material

The pipes connecting to the inlet and outlet of the water heater must be

strong enough to withstand water pressure up to 1.40 MPa.

▪Pipe Size

¾ (20mm) copper pipes are to be used for cold water inlet and hot water

outlet.

▪Connection

Water connections are located at the side of

the heater. Heat must not be applied at these

connections as it can damage the internal dip

tubes.

▪Install a drain

The T&P Relief valve is supplied with the

heater. This is to protect the heater from

excessive pressure and temperature. It is

recommended that a routine preventative

maintenance is carrying out at least once in every 6 mouths.

Lift and release the lever handle on the temperature pressure relief valve

to make certain that the valve operates freely and allow several gallons of

water to flush through the discharge line. Ensure the discharge water is

directed to an open drain.

If the main pressure is too low, the amount of hot water delivered to multiple

points will be unsatisfactory. Thus a booster pump is suggested to be fitted to

increase the pressure. A pressure-limiting valve is suggested to be fitted if the

main pressure exceeds the rated maximum pressure.

Connection -- Electrical

DO NOT turn on the power supply to the water heater until the water heater

is filled with water and satisfactory megger reading is obtained.

▪Electrical connection must be undertaken by a qualified electrician.

▪The water heater shall be connected to single phase AC supply and its

rated power is 220-240V 50Hz. Refer to rating label for input in wattage.
