INSTALLATION RULES
Location Selection:
The place where the water booster will work should be closed in such a way that
it is protected from external factors such as rain and frost. It should be placed in
such a way that it is not affected by heat sources such as burners and boilers that
may be present in the vicinity. Gaps should be left around the water booster for
maintenance and repair purposes.
If the water booster is to be fed from the tank, the distance (horizontal) between the
tank and the water booster should be at most 10 meters.
Water Suction Installation:
The water booster should be fed from the water tank. Do not connect directly to
the municipal water system.
The bottom of the tank should be in the same plane as the water booster. This
ensures that there is always water in the water booster suction inlet and prevents the
pump from producing air.
Suction from the tank at the lower level should never be done. Damage that may
occur on the water booster as a result of such applications is not covered by the
warranty.
All connections in the suction line must be sealed and air must not enter the
suction pipe.
Pumps should not be forced during water suction. For water boosters with single
pump, the diameter of pump suction pipe should be one size larger than the water
inlet diameter, and for water boosters with twin and triple pump, the diameter of pump
suction pipe should be the same with the suction collector diameter. Inner diameters
of plastic pipes are narrow compared to galvanized ones. If a plastic pipe is to be
used, the dimension providing the inside diameter of the galvanized pipe should be
used.
Other Installation Conditions:
The water booster inlet must be fitted with a gate valve, and its outlet must be
fitted with a gate valve and a check valve. Thus, it will be possible to remove the
water booster from the installation for maintenance and repair.
It is preferable to connect the water booster to the installation with flexible hoses.
Thus, the loads in the installation will not be reflected to the water booster and
the vibration and sound of the water booster will not pass to the installation.
The water booster must be fixed to the floor with bolts. In this way, the sound from
vibration will be prevented to a great extent.
Water Properties:
The water to be used in the water booster should be clean, free of solid particles and
temperature between 0-35 ºC. Ambient temperature should be maximum 40 ºC. The
water in the water booster should not be allowed to freeze.
