Please carefully note for the installation
1. Make sure the filter is working under pressure, and using a pressure control valve when the sys-
tems using a booster pump.
2. If the pump position is higher than the water level, which is not recommended in section 2, it
requires to install the back water control valve.
3. If the pump position is lower than the water level as recommended, it requires installing an isola-
tion valve. It could stop the water return back for general care and maintenance.
4. Reducing the connect adaptors and hose connecting bending as less as possible. Decreasing the
water flow scrub, it could reach the maximum effective.
5. Ensure solvents are not excessively applied to fittings as this could run into o-ring and cause
damage of the sealing's.
6. Do not over tighten fittings or adapters.

Installation of pump inlet and outlet hose
The pump is developed according to the latest technology. These preventive actions during installation
will ensure a trouble-free operation for many years. Use a pump inlet hose with the same diameter as
the suction port of the pump at least 40 mm (1½" female). The weight of the plumbing's and fittings is
to be independently supported and not carried by the pump.
The pump inlet must be installed under the water level of the pool, because the pump works
with an intake water supply.
For easier maintenance and care, we recommend the installation of an isolation valve. The advantage
is, that by closing the isolation valve no water runs out of the pool.
Make sure, there is sufficient in the sand filter tank before priming the pump
If the pump does not prime, please observe the notes in the section trouble shooting.
Make sure, all inlet and outlet valves are open, before priming the pump. Otherwise this could cause
severe damage of the pump.
6.4.
Fixed installation
For fixed installation of the electrical connection, make sure the plug can be easily
reached and is visible. For fixed installation the pump should be placed on a solid, hor-
izontal surface.
Please note:
- If the filter is located above the water surface, a check-valve should be installed so
that is always sufficient water in the sand filter tank and pump.
- If the filter is installed below the water surface, a shut-off valve should be installed.
This prevents unnecessary water flow during maintenance.
