4.3 Position for assembling

The delivery position

is position A

The terminal box must not

point downwards

(M,N,O,P),

as otherwise

water may

penetrate easily.

Before installing the pump,

the terminal box can be

turned by 90° in each case.

To do this, undo the casing’s

4 screws and turn the motor

head to the required terminal

box position.

Do not shift or damage the

seal between the motor and

pump casing.

After inserting

the screws, tighten them up

diagonally.

4.4 Installation

Installation only after

completion of all welding

and soldering work.

Be sure to avoid any water

dripping onto the pump

motor and especially

the terminal box.

The shaft must always

be horizontal, never vertical.

Install the pump casing

stressfree in the system.

Security measures must be taken to see that persons

do not inadvertently come into contact with the hot

surface areas of the pump.

Install a stop slide valve before and after the pump.

This will save the whole system having to be drained and refilled

in the event of any possible replacement of the pump.

4.5 Direction of flow

The arrow on the pump casing indicates the direction of flow.
