3.3 Description booster unit HMP
All booster units are equipped with a 20l diaphragm pressure vessel. The diaphragm pressure vessels are available in 3 variants, painted
steel, powder-coated steel and made of stainless steel.
The pumps are equipped with the electronic pressure switch ZP Control 01 Basic, which automatically switches the device on and off
and secondly, protects the pump from running dry, so that the system can be used as a automatically working domestic water station.
The pump starts and stops depending on the withdrawal of water, d. H. when closing (for example the faucet) it will be switched off
automatically, after opening and the resulting pressure loss it will be switched on again.
In order to adapt the functions of the pressure switch exactly to your installation situation, use the enclosed operating
instructions for the pressure switch ZP Control 01 Basic!
4.. Installation and commencement of operation
Before starting any work on the pump/motor make sure that the electric supply has been switched off and that it can
not be accidentally switched on.
Before installing and starting please check the pump for possible damages (i.e. during transport) to prevent personal
injury by electrical shock.
The pump must be installed in a horizontal position.
For best performance the dimension of the inlet-pipe (suction-hose or –pipe) must be min. 1" (25mm) and outlet (pressure-hose or –pipe)
min. ¾" (20mm). To avoid friction loss we recommend use the same dimensions for inlet and outlet.
Before starting the pump- body must be filled up with water. To avoid any damages of the pump hydraulics and seals, the pump must not run
dry! For avoiding air-locks the suction- hose/-pipe should be installed with a gradient of 2% up to the pump.
Using a foot- valve (non-return valve) with strainer is recommended for the jet pumps and a matter of urgent necessity
CAUTION
for booster kits.
In addition the suction hose/ -pipe should be fitted with a strainer with 2mm maximum particles size. Do not install additional fine filters,
water meters etc. in the suction line of the pump! These components are unnecessary flow resistance; especially with fine filters there is a
risk that they become clogged and cause damage to the pump. The strainer on the intake (preferably floating withdrawal) is sufficient for the
protection of the pump! If a fine filter is required, it may be installed in the pressure line. Here then even a backwash fine filter should be
used. This facilitates the regular filter cleaning.
Remark: Increasing the suction pipe length will decreasing the pump performance.
When suction – and pressure hose or -pipe are fitted and are airtight, the pump can be filled with water. Therefore remove the plug and fill
the pump with water. Filling should be done carefully to the outlet (pressure) – connection or filling to the connection at the top of the pump-
body. Tighten the valve using fingers only. Also fill the sucking hose/ -pipe with water for best performance.
The connection on the suction side (inlet) must be absolutely air –tight. Otherwise the pump will not build up a vacuum which is necessary
for priming. A hose should be a vacuum type. Depending on the length of the suction hose, the intake time may be a few minutes. If the
pump does not deliver even after approx. 3-5 minutes, this may be due to the following reasons:
- There is still air in the pump and they must be completely filled again.
- The suction line is leaking and the pump is drawing air.
- The suction screen is clogged.
- The suction hose is kinked.
- The maximum suction height of 8.5 m has been exceeded.
