5 - Installation

Refer to Fig. A, B and C for installation directions.
- Before installation, check if the plumbing system has been constructed according to
the applicable plumbing code.
- Avoid all kinds of stress by using the wall bracket provided. Should the use of the
wall bracket be impossible, the installer (qualified and licensed personnel) shall be
responsible for the most appropriate installation avoiding stress which may affect
the filter's integrity.
- Connect the inlet to the product's side with the arrow IN and the oulet to the side
with the arrow OUT. (Fig. B)
- Connect to pipes using tapered (conical) fittings ONLY in the case of NPT
marked filter housing and/or in the case of filter housing specified as NPT in
the label affixed in the package of the product. Preferably connect to pipes
using flexible hoses.
- Connect to pipes using BSP (cylindrical) fittings in the case the filter housing is not
marked NPT or not specified as NPT on the package label. Preferably connect to pipes
using flexible hoses.
- Use only sealing tape as a sealant for the connections.
- The installation of a by-pass is recommended (see Fig. A).
- Install the provided drain kit to the filter sump: screw the drain-valve to sump male
threaded connection, then screw the drain funnel (or the hose fitting) to the drain-
valve, making sure the 2 gaskets provided with the ball-valve are in place and well
positioned. (If you have a model with female threaded sump connection, screw the
provided male threaded junction to sump first and then screw the drain-valve).
- In case of HYDRA-M (models with gauges): screw the provided gauges to the
dedicated ports on top of Hydra head, using sealing tape to provide tightening.
- Connect a reinforced rubber hose to the drain funnel (or hose fitting) at the base of
the filter, secure with a clamp and have it discharge into the drain (see figures D1
and D2). The drain point must be lower than the drain funnel or hose fitting. The
rubber hose must not be more than 6.5 feet (2 metres) long.
avoid bending or pinching the rubber tube reinforced with canvas: this could
generate counter-pressure against the drain with consequent malfunctions.
