To brace flanges with a side longer than 40 cm, it is
advisable to connect them in the middle with another
screw clamp which prevents flange bar gappin (Figure 15).

In the case of applying paint to the outer or inner
part of the fan, the thickness of the paint must not be
greater than 0.2 mm. When repairing a damaged coa-
ting, the existing coating must be completely sanded
and then re-applied to a maximum thickness of 0.2 mm.
It is strictly forbidden to overlap the existing coating!
Installation, maintenance, service
The fan basically does not require maintenance. During op-
eration, it is particularly necessary to supervise the proper
functioning of the fan, smooth operation, care for the
cleanliness of the fan and its surroundings, load the fan only
within the range of its performance characteristics.
In the event of a fault, thoroughly check whether the mains
voltage is disconnected. Check that there are no foreign
objects in the fan and that the fan rotates freely. If the fan
does not start again after powering on, perform the follow-
ing actions depending on the fan protection method:
The rotating assembly must be balanced according to
the quality levels specified in ČSN ISO 14694.
The complete fan must meet the vibration levels recom-
mended in ČSN ISO 14694, corresponding to its size and
use (see ČSN ISO 14694:2014, 8.3 and 8.4).
Check and adjust the balance at intervals according to
the operating conditions of the fan, but at least once a year.
If the fan is protected by the STD protection relay, turn
the fan off and on using the buttons on the protection relay.
If the fan is protected by a TRN controller, turn the fan
off and on with the switch on the remote control of the con-
troller.
If the fan does not start, check the wiring and measure the
resistance of the electric motor winding. If the motor is
burnt, contact your supplier.
Attention! When carrying out maintenance or repairs,
always disconnect the device from the mains!
Wiring
The wiring can be performed only by a qualified worker
licensed in accordance with national regulations.
The fans are equipped with a plastic connection terminal
block – Zone 1 environment,
The terminal box is screwed onto the fan casing and is equi-
pped with screw terminals with a description (Figure 16).
