Fan and Motor Maintenance
TrilliumSeries™ Adiabatic Producs use axial fan(s) with variable speed, electronically
commutated motors and as such require little maintenance. As the fan are provided with
sealed bearings, lubrication is not required. With the fan(s) running, check for any unusual
noises or vibrations.
Coil Maintenance
Coil types will vary depending on the model and design. Proper coil maintenance should
be followed regardless of coil type.
• To keep the coils in optimum condition, ensure that the Self-Clean Cycle is enabled.
See pages 30 and 41 for more details.
• To inspect the coil, the Pre-Cooler Pads must be removed and the unit must be
operating in dry mode. It is recommended to perform coil maintenance when the
pads are dry as they are easier to remove than when they are wet. The coil should be
inspected quarterly.
• Inspect the coil surface. Any corrosion, damage, or obstructions must be corrected.
• Do not use sharp or pointed objects, including screwdrivers and similar, near the coil
or to realign microchannel fins. Also, do not use harsh chemicals or extreme water
pressure.
• To manually clean the coils, use a standard garden hose. Never use a brush or
pressure washer. First, rinse the outside surface dust and dirt into the water collection
gutters and the sump. Continue to rinse until the water easily flows to the inside of
the unit and into the sump.
