Installation And Electrical Connection; Hydraulic Connection - Wilo HiControl 1 Notice De Montage Et De Mise En Service

English
immediately starts working at the factory preset 1.5 bar. The pump continues to
operate as long as there is a minimum flow (> 95 l/h) in the pipes. When the tap is
turned off, the pump will automatically stop after a 10-second time delay.
• The automatic control system protects the pump in the event of low water. The
motor will stop after 30 seconds. The stopped motor is shown by the red indicator
light turning on. Press the RESET button to restart the pump.
• The pump is stopped when a flow of < 95 l/h is detected, and restarted once
the 1.5-bar pressure threshold is reached. Dry-running faults are managed with
automatic restarts every 30 minutes for a period of 24 hours.
• The pump can be operated manually by holding down the button on the front
(hold down this button during priming). The factory preset cut-in pressure ensures
correct operation up to a maximum of 10 metres from the height of the highest
tap above the control system.
• The electronic controller controls when the pump starts and stops, in the absence
of the opening or closing of taps or valves in the system. A distinctive feature of
this product is its ability to maintain pressure in the water pipe network with the
taps turned off.

7 Installation and electrical connection

All installation and electrical connection work must be carried out solely by
authorised and qualified personnel, in accordance with applicable regulations.
WARNING! Risk of physical injury!
The applicable regulations for the prevention of accidents must be complied with.
WARNING! Risk of electric shock!
Danger from electrical current must be eliminated.
7.1 Upon receipt of the product
• Unpack the automatic control system and recycle or dispose of the packaging in
an environmentally responsible manner.
7.2 Installation
• The automatic control system HiControl 1 must be strictly installed in the upright
position by connecting the suction directly to the discharge of the pump.
• As the automatic control system is fitted with an integrated non-return valve, we
strongly discourage its installation in a pipework which already has a non-return
valve.

7.3 Hydraulic connection

• We recommend installing the gate valves on the suction and discharge side of the
pump.
• The cross-section of the pipe must be equal to or greater than the diameter of the
suction port on the pump housing.
• A non-return valve may be placed at the discharge port to protect the pump from
water hammer.
