CAUTION
Pumps and units which carry hazardous materials must be decontaminated.
Immediately after completion of the work all safety and protection coverings should be reinstalled and / or switched on.
Please observe all instructions set out in the section on “Installation / commencement of operation”
before returning the machine to service.
2.7 Non-manufacturer modification and spare part production
Modifications or alterations of the machine are only permitted after consultation with the manufacturer. Original spare parts and accessories
authorised by the manufacturer ensure safety. The use of other parts can invalidate any liability of the manufacturer for consequential
damage.
2.8 Unauthorised usage
The safety of the delivered pump is only guaranteed by usage according to the section 1 – General - of the instructions. The listed maximum
ratings as per specification should under no circumstances be exceeded. The improper use of the pump, i.e. pumping of air or explosive
media is strictly forbidden.
Also, this booster- kit, as a fully automatic utensil may need supervision from time to time and ensure if left
inactive for long periods that the electrical supply to the pump is switch off.

The pumps are fitted with a robust single– phase electric motor. The most important seal is a mechanical seal between motor and pump–
body.
The scope of delivery of the
booster units
HAE includes an electronic pressure switch with dry-running protection.
The booster-

. All units have a 1,5m
power supply cable with plug for 230 V 50 Hz single-phase. Other voltages are possible on demand. Please note the data printed on the
type-plate.
- This pump must be connected to an earthed outlet.
- Do not lower or lift the pump by means of the power cable.
- A damaged power cable must be replaced immediately by a qualified electrician. Danger of personal injury by electrical
shock if operated with a damaged cable!
- If the pump is connected to an electric installation where an earth-leakage circuit breaker (CB) is used as an additional
protection, this circuit breaker must trip out when earth fault current exceeds 30mA.
- The pump must not drop in water and also not submersible.
- Any operation of the pump next to a swimming pool or garden pond is only permitted if the unit is installed in accordance
to local legislations.
It is strictly forbidden to swim while using the pump in the swimming pool.
- If in doubt consult a qualified electrician.

Description
booster set
HAE
The pumps are equipped with the electronic pressure switch ZD 15 or ZD 20 at the discharge port, 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 power plug of the pump is connected to the coupling of the pressure switch. By connecting the mains cable (pressure switch) to the mains,
the device takes over the control of the pump.
After installation, the pump is started for the first time by using the RESTART key.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 reduce the switch-on frequency of the pump, the switch-off is delayed after closing the tap between approx. 7
and 15 sec.
The pressure switch is set at the factory and switches the pump on when the operating pressure drops below 1.5 bar. This switch-
on pressure can not be changed. In order to reach the switch-on pressure, the highest extraction point may be no more than 15 m
above the pressure switch!
ATTENTION If the booster set is used as a pressure booster system; that means, the intake side already entered into the booster
set with a pre-pressure, so this pre-pressure may not be higher than 1.5 bar, otherwise the system can not be turned on by the
pressure switch.
