5. INSTALLATION
Two standard cases:
• Fig. 1: Pump in suction
• Fig. 2: Pump under pressure from storage tank (item 9) or town
water supply (item 10).
5.1. Installation
Install the pump in a place that is easy to reach, protected from frost,
and as close as possible to the place from which water is drawn.
Install the pump on a foundation block or directly on a smooth, level floor.
Pump attached by two holes for 8-mm-dia. studs.
Required tools :
- Open-end wrench 13 and 19,
- Allen wrench 6,
- Screwdriver.
Bear in mind that the altitude of the place of
