5. Commissioning
Procedure
5.10 Humidifiers and Water
Quality
The humidifier water supply quality is very
important to ensure correct operation.
The use of incorrectly treated or
untreated water in this equipment may
result in scaling, erosion, corrosion,
algae, or slime.
The services of a qualified water
treatment specialist should be
engaged to determine what treatment,
if any, is required. The Trane warranty
specifically excludes liability for
corrosion or deterioration. Trane
assumes no responsibility for
equipment damage or failure that
results from the use of treated water,
or saline, or brackish water.
Please refer to the individual supplier's
installation, operation, and maintenance
manual for additional information.
5.11 Gas Burners
The gas burner supplier will commission
this equipment when installed on site.
Please refer to the individual supplier's
installation, operation, and maintenance
manual for additional information.
5.12 HEPA Filters
The HEPA filter section is supplied with
complete front withdrawal framework.
HEPA filters are supplied in original
packaging with the unit.
A specialist sealing company must be
employed to seal up the filter framework,
fit and seal the HEPA filters, and complete
a DOP test or equivalent.
5.13 Inverters
The inverter needs to be set up and run in
accordance with the supplier's IOM.
Please refer to the individual supplier's
installation, operation, and maintenance
manual for additional information.
5.14 Controls
See controls IOM and wiring diagrams.
Please refer to the individual supplier's
installation, operation, and maintenance
manual for additional information.
5.15 Test Run
Following the completion of all
preparatory work, the unit is started up for
a test run.
To conduct a test run that involves the
measurement of motor and fan
performance, the unit must be
connected to the complete installation.
All access doors must all be closed to
avoid pressure loss in the installation,
which may result in motor damage.
Before staring the fan, open
ALL
dampers. The fan must not be started
if the dampers are closed. When
starting
the fan, open the dampers.
The fan should not work against
closed dampers.
After switching on, check that the
direction of the rotation is correct. In
addition, the running power consumption
should be checked on all phases and
compared with the power data on the
nameplate. If the running power is too
high, there is probably a faulty connection
and the unit must be switched off
immediately. Check the fan and motor
bearings for undue noise. Measure the air
volume and external pressure.
The following situations may arise:
1. The air volume is lower, as the system
pressure is much higher than
designed.
2. The air volume is higher, as the system
pressure is much lower than designed.
Increasing the fan speed should only
be carried out after careful study of the
measured point on the appropriate fan
curve.
In extreme cases exchanging the motor,
fan and drive may be necessary.
The adjustment of variable belt-drive
pulleys is carried out with the system at
rest, ensuring that the system is not
restarted unexpectedly. Remove the
pulley safety screws and turn through half
of the pulley circumference to carry this
out. Then retighten the screws and
readjust the pulley belt tension.
Following any change in the pulley ratio,
the motor power consumption must be
rechecked.
The nominal output rating quoted on the
nameplate must not be exceeded.
In all cases of airflow not conforming to
the specifications, please contact your
sales office.
