Precautions for installation of domestic hot water tank
Warning
Installation
Mandatory
Check leakage of the tank itself before installation if existing tank is used.
Be careful not to let your body touch the heating pipe directly.
(It may cause a burn.)
An expansion tank with insufficient capacity may provide poor heating performance.
The structure should be able to withstand the tank load when installing the boiler.
(including the load of water in the tank)
The domestic hot water tank should be level.
Piping should be arranged horizontal or vertical simply and accurately.
Do not allow foreign substances to enter the domestic hot water tank
Do not use eye bolts for transportation as materials for piping connection.
Clean the pipes before starting the plumbing work.
Make sure the sizes of the hot water suppy and return piping are identical.
If the room to be heated is located higher than the domestic hot water tank, use
a circulation pump with a check valve or a lifting check valve to prevent natural
convection.
As the maximum use pressure of the domestic hot water tank is 1kgf/
㎠
, the
expansin tank may be installed at elevations up to 10m.
Insulation should be applied to all exposed pipes to prevent freezing and bursting and heat loss.
(Without heat retaining treatment, damages to the insulation, electric short or freezing and
bursting may occur by dew condensation, which may result in human or property damages.)
