Installation
Caution
• Please wait for 30 minutes before using the heater for the first time.
• The heater should only be connected to a power source after a full installation which ensures
secure mounting, piping, wiring and filling of the tank with water.
• To prevent injuries from lifting heavy equipment, the water heater should be installed by at least
3 persons and where necessary, aid of a forklift.
• The water heater must be installed by a qualified person
Tank installation
• Make sure the floor where the tank is placed can bear approximately 1.5 times weight of the tank
when it is fully filled with water.
• During the installation, the tank cannot be tilted over 30º
• Unit should rest on a flameproof, fixed base below of at least 20mm height with adequate drainage.
• The tank of the water heater shall be installed near to the power socket, sewer mouth and the area
where water is needed (Figure 4).
• Because high temperature water may drain from the temperature and pressure relief valve on the
tank during the usage of the water heater, the drainage pipes of the pressure relief port must be
connected to floor drain to prevent scald.
• The water heater should be located in an area where leakage of the water heater or the pipe joint
will not damage to the subjects around or the lower floors of the building.
Installation environment
• The unit is suitable for outdoor installation
• If the water heater is installed in the places where it would be easily subject to lightning strike, such
as on the roof top of buildings, lightning-protection is necessary.
• Do not power off the water heater when the ambient temperature is lower than 5°C. If required,
please drain out water completely in advance.
• Installation location to be away from oil smoke, severe electromagnetic waves, acid or alkaline steam.
• The airflow surrounding the unit must be unrestricted
Pipe connection
• Install the inlet and outlet according to the diagram.
• If the water pressure of the water inlet pipe is near to or exceeds the release value of relief valve
(1.03MPa), install a pressure reducing valve in the water inlet pipe far from the water heater.
• Hot water outlet pipes should be properly insulated.
• There is a tube at the hot outlet connection of the water heater. Please do not remove or damage
it during installation process.
• Apply proper sealant to the pipe joints to prevent leakage. Do not over-tighten the safety valve to
avoid damage.
