German Pool Gpu Series Central Storage Electric Water Heater User Manual (+ PDF)

Do not allow children to touch or play with the water heater.
Supervision is required during use to prevent the danger of scalds,
electrical shock, or injuries.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory, or mental capabilities,
or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a
person responsible for their safety.
An electric-leakage protection device must be installed to the
power inlet. The electric current of this protection device should
be below 30mA.
Please install the water heater in accordance with the
instructions stated in the user manual. German Pool will NOT
provide warranty service on any product installed with unauthorized
components or devices.
The PTV device must be tested and operated regularly (suggested
once every 3 months) to remove calcium carbonate deposits and to
ensure that it is not blocked.
The PTV drain pipe must be installed continuously downwards at
an angle and the surroundings must not be frosted. The drain pipe
must be left open to the atmosphere to ensure that the hot water
drips from the PTV will not endanger personal safety or cause

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. you can also use the mounting bracket for positioning.

Connecting PTV and Inlet/Outlet Pipes
A Pressure & Temperature Relief Valve (PTV) is supplied with each GPU water heater. Water will be released through the PTV when water temperature reaches 90°C or when water pressure reaches 1000 kPa in the inner tank. (It is normal that small amount of water may drip out.)
PTV and water inlet & outlet must be installed according to the following instructions:
1. Fit PTV to the marked position (normally it is located on the upper side of the water heater and is labeled “PTV”).
2. When connecting the pipe,the PTV must point downward.The outlet of the discharge pipe connecting the PTV must be positioned approximately 25-50mm away from the ground, so that it is easily observable when hot water is being drained to ensure safety.
3. Connect the inlet pipe (blue) with water supply. Then connect the outlet pipes (red) with supply pipe leading to points of use. The diameter of piping should be 1/2″ BSP.
4. Turn on the hot water tap. Turn on water supply switch until the inner tank has been filled up with water. The inner tank has been filled up when water flows from the water tap.

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.

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 contract separation of at least 3mm must be present.
Testing
When the piping and wiring are connected and inner tank has been filled with water, switch on the power. The indicator on the water heater 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.

! WARNING!
The water heater must be permanently and reliably connected to the water pipe and must not be connected with a hose.

! 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; 2. Completely drain the residual water 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

Pressure & Temperature Relief Valve (PTV)
– The discharge pipe connecting to the PTV must be pointing downward and be left open to the atmosphere in a frost-free environment.
– Turn the lift handle or rotational cup of the PTV regularly in order to prevent deposits in water causing blockage to the easing gear.
– When water is discharged through PTV pipe, shut off power and water supply immediately. Then contact our Customer Service Centre for repair. (It is normal that small amount of water may drip out.)
Under normal working conditions, incoming pressure should not exceed 0.6 MPa. Otherwise, a separate pressure control device is necessary. (It is normal that small amount of water may drip from PTV after installation of pressure limiting valve.)
Note
When incoming water pressure exceeds 0.6 MPa, German Pool will not provide any repair service until a pressure control device is installed.
Draining
To drain out water from the inner tank, first switch off both power and water supply. Let hot water inside the inner tank cool down. Then unscrew the drain pipe nut to release water.
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.

Installation Instructions

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.
