Biral WX 13 [18/52] Assembly

4. Assembly

4.1 IInstallation

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.

Install the pump casing stressfree in the system.

Install stop slide valve before and after the pump.

This will avoid having to drain and refill the system

if the pump has to be replaced.

4.2 Position

of the terminal box

The delivery position

is position A, (corresponds

to assembly position F, K)

The arrow on the pump

housing indicates

the direction of flow.

The motor shaft always

has to be horizontal,

never vertical.

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.
