Gardena 4000/5 Manuale di istruzioni per l'uso

4. Using the Equipment for the First Time

Position of equipment:

Install automatic domestic

water system permanently:

Connect the hose to the

suction side:

Art. 1723 /

Art. 1724

The point at which the unit is fixed must be sound, dry and well

ventilated and must permit the pump to be set up in a stable

position.

➔ Install the pump at a safe distance (min. 2 m) from the pump-

ing medium.

The pump must be installed in a location with low air humidity

and sufficient ventilation in the area of the ventilation slots. It

must be at a distance of at least 5 cm from the walls. No dirt

contamination (e.g. sand or earth) may be sucked in through the

ventilation slots.

The mounting plate prevents the pump moving.

1. Screw mounting plate

2. Place pump on the base with both feet

Set the pump such that a suitably large container can be positioned

below the drain screw for emptying the pump or unit

If possible, install the pump higher than the surface of the water to

be pumped. If this is not possible, install a vacuum-resistant shut-

off device between the pump and the suction hose, for example

for cleaning the integrated filter.

If you install your Electronic Pressure Pump permanently indoors to

supply water for domestic use, connect your pump to the pipe

network using flexible hoses rather than rigid pipes. This will help

reduce noise and prevent damage to the manometric switch

due to vibration.

If the system is being installed permanently, please fit suitable

shut-off devices on both the intake and delivery sides. This is

important e.g. for maintenance and cleaning work or if the system

is being shut down.

The connection pieces on the intake and delivery sides must

only be tightened by hand.

Do not use any water hose snap connection system components

on the intake side. A vacuum-tight suction hose must be used e.g.

• GARDENA Suction Hose art. 1411

• GARDENA borehole Suction Hose art. 1729.

To reduce the pump repriming time, we recommend:

• using a suction hose with backflow preventer, which prevents

the suction hose emptying automatically when the Pressure

Tank Unit is switched off

• If the suction heights are high, use a suction hose with a small

diameter.

1. Connect vacuum-tight suction hose

(e.g. art. 1723 / 1724)

and screw in place so that it is airtight.

2. For suction heights exceeding 4 m also secure the suction

hose

(e.g. by fastening it to a wooden post).

This relieves the pump of the weight of the suction hose.

If very fine dirt is present, we recommend the use of a

GARDENA pump preliminary filter art. 1730 / 1731 in addition

to the integrated filter.
