Filters
The filter cells or media (bag filters, heap filters, and roll filters) delivered separately must be installed into the unit
prior starting the unit.
Check that the filter is correctly fitted and that the entering air side of the filter is exposed to the contaminated air
stream. Refer to the certified submittals which maybe different.
If roll filters are used, check that the filter unit drive motor and the switch control are working correctly.
Humidifiers
The evaporative humidifiers with or without recirculating pump are provided with a water flow control valve.
During fan operation, with the door closed, adjust the water flow control valve to prevent water leakage from the
pump hydroscopic plastic honeycomb humidifier.
The following safety procedures are strongly recommended:
• Connect the power supply to the pump.
• Check that pump rotation is correct.
• Check that access doors of all sections, but the one being used, are closed. The door of the section in use should be
kept in open position with a shim.
• Slightly open the water flow control valve towards the humidifier.
• If the humidifier is with honeycomb, ensure there is no water leakage from the honeycomb humidifier. If you
notice leakage, close the valve and check again. If it is operating correctly, open the control valve until the system
reaches its best balance.
• If the humidifier is with nozzles, check that water is not coming out from the limit of humidification section and do
not spray on the casing.
• Measure the absorbed power and check that it matches the data indicated on the pump name plate.
CAUTION!
The above mentioned operations should be performed from outside of the unit. Do not enter the sections.
CAUTION!
The pump must not be dry run to avoid any risk of overheating.
No warranty claims will be acknowledged if pump or pump motor damage is caused by a dry run.
Note: If installation and start-up do not occur immediately after delivery, take the following precautions:
• Store the equipment in an area that is not exposed to excessive humidity.
• Take special care to protect electrical components.
• Periodically, manually turn all moving parts to avoid any blocking risks.
CAUTION!
for other type of humidifier (steam, compressed water, water and compressed air, others), refer to
Manufacturer instruction and IOM.
Water quality for humidifiers and air washers
The information hereunder which refers to the water treatment is given for reference only. Water quality is of prime
concern to ensure proper operation of humidifier and air washer.
The water hardness of the freshwater has to be measured before considering any water treatment.
CAUTION!
The use of improperly 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 which results from the use of untreated or
improperly treated water or saline or brackish water.
