Hollex 24V Hydrofoor Water Pressure System User Manual
The Hollex Water Pressure System consists of a par diaphrAGM pump mounted on a horizontal kettle with a content of 8 or 24 liters. The kettle is provided with a rubber bellow which contains the water. Between this bellow and the steel kettle, an amount of air is present under pressure. This pressure (measured with no water in the below) has to be 0.1 bar low-The than the engaging pressure of the pump. By standard, this pressure is set to 1.1 bar, whereas the disengage pressure is set to 2.1 bar. connections The suction and pressure sides of the unit are provided with ½” BSP hose connections. The length of the suction hose must be 6 meters or less, taking into account a suction height of 1.5 meters max. The maximum current in amps is indicated on the pump engine. This value determines the wire cross-section and the protection or fuse used for the pump. On the kettle, a pressure switch is mounted (not all types) which has two poles. the red wire is positive and the black wire is negative. Switching the two wires, however, does not damage the pump or lessen its functioning.
Preparation Check whether the voltage of the unit is in concordance with the
main voltage of the vessel. Check all con-connections and ensure you have
water in the tank. Open all taps and engage the pump. Only if no more
air is out of the taps, can they be closed. Now the pump will the bellow with
water. After approximately 1½ minutes the pressure switch will disengage the
pump (at a pressure of 2.1 bars). Open one or more taps and wait until the
pump engages again. Check the pressure at engaging and disengaging by looking
at the press sure-gauge (not all types). Repeat this process several times to
rinse the piping and the bellow. Clean the suction Filter and the water
pressure unit is ready for use.
Maintenance
- Check regularly the starting pressure in the kettle with a meter. This May only be performed when no water is present in the bellow, so when all taps are open and the pump has been switched.
- When too little air is present, the bellow may be torn. Too little air can be noticed because the pump will be engaged too quickly, even when there’s only used a small amount of water.
- With too much air in the kettle, the pump will only engage when no more water comes out of the taps This can cause the water heater to be disengaged.
- Make sure there is always enough voltage on the pump. When the voltage is too low, the current will increase, causing the motor to overheat.
- So, never let the pump run for a long period to prevent overheating.
The Hollex Drinking water supply layer consists of a Par Member pump mounted
on a horizontal Pressure tank of 8 or 24 liters. The Tank is equipped with
rubber bellows in which the water is kept becomes. Between this brat and the
stole Tthanks is a lot of air under pressure. This pressure should be about
0.1 bar lower (measured without W ater in the bellows) because of the switch-
on pressure of the pump. default this switch-on pressure is set to 1.1 bar and
the cut-out pressure to 2.1 bars. connections The suction and pressure sides
of the system are equipped with a ½” G attachment conclusions. The length of
the suction line must not be more than 6 meters because the maximum suction
height is 1.5 meters may The maximum current in amperes is indicated on the
pump motor. This w ert determines the line cross-section and the protection or
the Fuse for the pump. The on the T thanks to the mounted pressure switch ter

the black death is negative, but if they are exchanged, the system is not
damaged.
Put in operation
