– Are the motor(s)/fan(s) rotating in the right direction?
– Are any servo motors rotating in the right direction?
– Have the end switches been adjusted to stand open at 90%?
– Have parts installed by third parties been tested to check that they are operational?
– Have all access doors been closed during testing of the installation?
– In the case of gas-fired units, never switch off the electrical voltage until the units have cooled
down completely.
3.3 Starting up components
3.4 5.6 Fan [4][5]
Make sure that the appliance is disconnected from the mains when working on it. Remove any
(red) transport blocks. The axis of the fan(s) must always be horizontal. A load may be applied to
the shock absorbers only under pressure. Check the fan motor’s direction of rotation. Remove
the V-belt(s). Always check the direction of rotation when the motor is not under load. If the
motor is not rotating in the required direction, the electrical wiring in the motor(s)’ branching
box must be removed. Once the correct direction of rotation has been established, reinstall the
V-belt(s). Check whether the pulleys are in a single line. Check that the V-belt(s) have the correct
tension. The motor(s) is (are) on slide rails, which provide sufficient scope to (post-) tension the
V-belt(s).
Tension the slide rails as follows:
– Unscrew screw 1
– Use screw 2 to set the v-belt to the correct tension.
– Retighten locking screw 1.
[4]
Once the unit has been fully operational for 0.5 and 4 hours, the V-belt(s) must be checked to en-
sure they are at the right tension. Once these tasks are complete, attach any protective grills (op-
tional). When the inspection doors are closed, the fan motor(s)’ current consumption can be
measured. Current consumptions can be measured correctly only if all the installation work has
been completed. The motor(s) and the fan(s) are selected on the basis of specifications provided
by the customer.
3.5 Filters [6]
– Check the filter safety setting and compare it with the values on the type plate.
– Check that the filters are correctly positioned (vertical).
– Check that the filters are sealed from damage.
3.6 Gravity shutter [7]
When installing the servo motors, make sure that no screws can hinder rotation of the fins in the
valve. The servo motors fitted are permitted a maximum torque of 20 Nm.
3.7 Flexible connection
To prevent vibrations to the (duct) system, the use of flexible connections is recommended. Make
sure that the flexible connections are able to move optimally. Where flexible connections could
come into contact with the external air, they must be properly thermally insulated to prevent
condensation.
In the Netherlands, flexible connections may not be used in a boiler room because of the risk of
fire. Any fire protection requirement may vary according to location. It is advisable to consult the
local regulations.
