Electrical connections of the unit

must only be established by autho-

rised specialists in compliance with

the applicable regulations of the

local electricity supply company as

well as the VDE installation requi-

rements relating to the unit.

Connection of the units

The units are ﬁtted with two-

speed, 400V three-phase axial

ﬂow fans as standard.

Speed selection takes place with

appropriate control units (accesso-

ry).

Changes in direction take place via

a pole changing switch or special

control unit (accessory).

Motor protection is provided via

integrated thermal contacts in

conjunction with a suitable control

unit (accessory).

Connection of the three-phase

motors to the respective control

units takes place via the associated

electrical wiring diagrams.

ATTENTION

Failure to observe the pertinent

requirements, operating inst-

ructions and electrical wiring

diagrams relating to the unit

can give rise to malfunctions

with consequential damage.

This will invalidate the war-

ranty!

Connection of several units

If necessary, several units (also

different sizes) can be operated

parallel via a control unit (accesso-

ry).

The total capacity of the con-

nected units must not exceed the

maximum switching capacity of

the respective control unit.

For thermal motor protection, the

thermal contacts of all motors

must be connected in series. See

separate wiring diagrams.

Only one external control device

(thermostat, day/night control,

etc.) can always be connected per

control unit.

Terminals in the unit

Fuse protection in the supply to

the control unit must be in compli-

ance with the applicable regulati-

ons.

The connections in the terminal

box must be connected to the

respective control unit (accessory).

When the fan is stationary,

the hydraulic supply must be

simultaneously interrupted.

ATTENTION

Only suitably trained specialists

may establish electrical con-

nections.

Connection to the local hy-

draulic system

Prior to connection to the local

hydraulic system, it must be en-

sured that the respective capacity

requirements of the unit can be

provided at all times.

■

Connection of the unit on the

water side must take place local-

ly via suitable pipe fittings and

shut-off valves in the flow and

return.

The use of compensators and

automatic venting devices is

recommended!

■

The connection side at the top

and the flow and return can be

connected as required.

■

The pipe connection thread sizes

is R 1“ internal thread.

■

The fin heat exchangers must be

thoroughly vented after installa-

tion.

Air cushions in the heat exchan-

ger will reduce the heating or

cooling capacity!
