Air washers
• Check that the fresh water supply is working correctly and that the water level is correct. Adjust as necessary.
• Depending upon the extent of water contamination, the degree of hardness and water treatment, any scale
deposits or other impurities must be cleaned off from the air washers. Any severe calcium deposits on components
such as spray pipes, droplet separators or strainers indicate that the treatment is inadequate.
• Deposits on spray pipes, strainers, air strengtheners and droplet separators may be treated with diluted formic
acid and subsequently rinsed off with clear water. In the case of droplet eliminators or air straightener blades of
plastic construction, any deposits may be occasionally removed by carefully flexing the components i.e. after they
have been dried off and removed from the module. Corroded or damaged droplet separator blades should be
replaced.
• Any strainers or sediment accumulations should be inspected and cleaned as necessary. Dismantle spray pipes
and clean. Check the fresh water feed, the overflow, siphon and the water tank for any sediment accumulation and
clean as necessary.
• Any spray pipes with erosion damage should be replaced.
• Never ream out spray pipe nozzles with sharp instruments. Flush out the spray pipe with a high pressure water jet,
with the spray pipe nozzles removed.
• Check that the setting of the sediment flushing valve (bleed-off) is correct.
Evaporative (Honeycomb) humidifier
Follow the instructions given in the Air Washers section. Any Honeycomb module strongly encrusted with calcium
deposits should be replaced. In the case of lightly contaminated components, with the air handling unit powered
off, add a suitable decalcifying agent to the circulating water and operate the pump until the deposits are dissolved.
Thoroughly wash off and flush through the system following this operation.
Trane cannot be held responsible for improper cleaning of the Honeycomb humidifiers. In order to avoid any excess
clogging of the honey comb humidifiers, it is recommended to interlock the spray pipe operation with the fan
operation.
Other humidification
For humidification with or without steam generator, atomizing nozzles or feeding cabinet, it is mandatory to follow
the manufacturer's instructions.
Dampers
Check for dirt and deposits, for any damage or signs of corrosion. Clean with pressurized air or steam. Check the easy
movement and correct operation of the dampers. If there is any tendency to jam, check the unit is not misleveled.
CAUTION!
Check that the linkage is firmly in place and tighten the screws if necessary.
Sound attenuators
Check for any dust deposits and clean with a vacuum cleaner as needed.
Weather louvers and hoods
Check for dirt and deposits, for any damage or signs of corrosion. Remove any leaves or foreign matter which may
have been drawn in.
