Installation

The domestic booster set is despatched mounted on a wooden pallet and covered in a protective film, it is
recommended that the unit be retained in the protective packaging until the product is to be installed. The unit

maintenance and service. The unit is fitted with adjustable feet that can be adjusted to ensure the unit is level
helping to reduce noise and vibration.

Electrical connections

Never operate this product with the inverter front panel removed.
Wait at least 5 minutes before removing front panel.
It is essential that this equipment is earthed to the building earth system.
Pump operates at 230v 50Hz.

Water supply and system connection

incoming water volume, if this is not the case then a pressure reducing valve should be fitted to reduce the
incoming mains water volume.
Extend the 22mm plastic overflow pipe from the rear of the unit to a position where an overflow will be noticed
and rectified.
Connect the discharge port 22mm compression (right hand rear of cabinet) to the system cold water inlet.
It is advisable to arrange a suitably valved by-pass line including non return valve from the incoming mains
water feed and the system cold fill point to enable the booster set to be bypassed in the advent of power
failure. A drain valve is positioned at the rear of the unit to enable the tank to be drained for cleaning.

Commissioning

the pump discharge pipe by releasing the push fit fitting. This will allow air to escape through the pump when
the tank is filled.

4. Open the water supply to the booster set and let the water tank fill with water until the ball valve closes

5. Thoroughly flush the whole system through to ensure any contaminates that may have entered the

will arrive pre-packaged and wired ready for installation.
This product has been fully run tested at our works under simulated site conditions. The unit
should be thoroughly checked for physical damage that may have been caused during transit.
If the unit is found to have damage it must be reported immediately and should not be installed.
The unit should be sited on level ground in position that will allow adequate room for general

The cable used for the incoming supply must be of adequate size to carry the motor full load
current. This is shown on the duty plate. The supply must provide thermal/short circuit protec­tion, a high sensitivity differential switch (0.03A) is also recommended.
All connections must be made using the appropriate wiring drawings for the equipment being
installed, with particular attention being paid to the supply voltages, shown on duty plate.

The base frame must be earth bonded directly to the building earth system

The power supply wiring should be arranged such that it enters the product through the rear of
the case and then into the appropriate cable gland on the inverter.

Connect the domestic booster water inlet 15mm compression (left side of cabinet) to a suitable
water supply. The water inlet to the ball cock has an internal isolation valve but it is advisable to
fit one external isolation valve for added ease of maintenance. If the pressure available at the
ball valve is below 0.3 bar, a low pressure orifice must be obtained and fitted.
It is the responsibility of the installer to ensure that the overflow is able to keep up with the

1. Ensure the water tank is clean; the pump is in the correct position with the anti-spin bracket
engaged and the drain valve closed. Ensure the by-pass lines (if fitted) are closed.

2. Check the vessel pre-charge, this should be set to 0.2 bar below the system
pressure, Re-charge with Nitrogen or dry air if required. Open vessel isolation valve.

3. With the power supply off, Close the discharge isolation valve and lift the Aquontroller off of

and stops further filling. Check the water level is correct and all joints are sound. Re-connect the Aquon
troller to the pump discharge pipe and open discharge valve, switch power supply on and slightly open
the furthest outlet, once all air has been evacuated close outlet and pump will stop.
