SETUP AND INSTALLATION

This device must be placed on a horizontal, rigid and level surface that is capable of supporting the

total weight of this device when lled with water. To prevent vibration or movement, place the device

on an elastic base support like a rubber mat. For stationary use, this device can be screwed down

rmly to the base with four screws.

When being used on garden ponds or swimming pools, this device must be set up to guard against

overowing and protected from being submerged.

the installation site must be well ventilated and protected against the effects of weather. If operating

this device indoors, you must ensure there is a drain in the ooring or a leak detection mechanism.

Before starting, check that the suction hose is sealed. Bubbles in the hose is an indication that there

may be leaks and may lead to device malfunction.

The suction line must be installed so that it does not exert any mechanical force

or tension on the pump. If the conveying medium is contaminated, a suction

lter must be used to pump from sand and dirt.

NOTE: A check valve is recommended so that the water does not run off when the pump is shut off.

All connections must be sealed with fermit paste or thread sealing tape to prevent leaks that cause

air exhaust and reduce or prevent water exhaust.

Hemp should be used in case of pipe threads from metal; synthetic thread must be sealed with

thread sealing tape.

All components of the suction line must be installed by a qualied technician.

The suction pipe should have an internal diameter of 25 mm and must be kink resistant and suitable

for vacuum use.

The suction line should be as short as possible, since the conveying capacity decreases as the

length of the line increases.
