Installation Instructions

Pre-Installation Notice

Installation should be done by a licensed technician using the supplied parts. German Pool is not responsible for any defect or damage caused by incorrect or unauthorized installation.

Positioning

Position water heater near water tap / point of use in order to minimize heat loss. For wall-mount style, appropriate anchor screws must be used and wall should be strong enough to withstand the weight of water heater. Keep a minimal distance between wall and water heater.

Connecting Inlet and Outlet Pipes

The diameter of piping is ½″ BSP. Make sure there is no leaking at the joints. Turn on hot water tap to fi ll up the inner tank until water flows from the shower head. Turn off hot water.

ATTENTION: The appliance  intended to be permanently connected to the water mains and not connected by a hose-set.

Electric Wiring

Use an independent wire (refer to table below) leading from the meter box and connect it to an independent on/off switch outside bathroom. Extend the wire through the grey wire grip on the water heater. Dismount the bottom plate and wire up Neutral (N), Life (L) and Earth ( ) terminals.

ATTENTION: This water heater must be earthed at all time.

Power Switch

The external switch is used to completely disconnect water heater from power supply. It should disconnect all poles, and a contact separation of at least 3 mm must be present. IEE wiring regulations should be observed when the water heater is installed in the bathroom.

Testing

Once the piping and wiring are connected and inner tank has been filled up with water, switch on the power. The indicator light will be lit. Turn control knob to the desired temperature (Max. temperature is 75°C). Do not use the control knob as an on/off switch.

Operating Instructions

WARNING

After initial installation and water and electricity testings, if the storage water heater will not be put to use immediately after testing is completed, make sure to follow these instructions:

1. Disconnect water and power source to the water heater;
2. Completely drain the residual water in the water heater;
3. When the water heater is finally put to normal use, user MUST first completely fill up the water heater with water BEFORE reconnecting the power source and commencing heating.

NOTE: If water source is from underground water or near river area where seawater intrusion is possible, user MUST COMPLY with all of the above steps to ensure proper function of water heater.

INSTALLATION REQUIREMENT

ATTENTION: When installing the water heater, must leave ample space for future maintenance and repair.

The minimum requirements are:

1. at least 100 mm space from the ceiling
2. at least 200 mm on either side of the wall
3. at least 300 mm underneath the heater

Water Shortage

During water shortage, do not drain water from inner tank. The heating element would be damaged if it is not submerged under water. When water supply resumes, turn on hot water tap and let water flows through the shower head before switching on the power.

Source of Water Supply

If the water source is a river, a well, underground water or has relatively high mineral content, user must clean the heating element regularly to ensure it will operate at optimum thermal efficiency.

Dripping

Due to thermal expansion, small amount of water may drip off from the shower head when the inner tank temperature is very high.

Outlet

The outlet of the water heater is supposed to act as a vent and should not be connected to any unauthorized piping attachment or device.
