Humidifier
The unit is provided with a self-contained, microprocessor-controlled steam generator type
humidifier. The steam generating humidifier uses a disposable cylinder with electronic
controls. The humidifier discharges pure steam with no material dust carry-over and has a self-
regulating automatic flush cycle.
Cylinders are disposable and do not requiring cleaning or maintenance. The humidifier fill
level, water conductivity and flush rate automatically adapt, both in frequency and duration, to
variations in the incoming water. The humidifier assembly is capacity field-adjustable and
includes a high-water probe. Drain duration and drain interval are also field-adjustable.
Humidifier Canisters
The steam generator type humidifier does not require maintenance other than to replace the
canister as required. The frequency of change will depend on usage and water type. A set of
the humidifier manufacturer’s instructions is included with the paperwork placed inside the unit
when it ships.
Refrigerant Filter Drier
Factory installed refrigerant filter driers do not normally require maintenance. When replacing
compressors or other repairs that open the refrigeration system to atmosphere, it is advisable to
replace the filter drier. The equivalent type and size should be used.
Plenum (Plug) Fans
Electronically Commutated (EC) motors with backward-curved plenum (plug) fans are
standard on all gForce units.
Maintenance is not required on electronically commutated (EC) motor/plenum fan modules. The
motors are sealed, have maintenance free ball bearings and permanent lubrication. The only
acceptable service is replacement.
WARNING: Due to the use of capacitors in the electronic systems of the
plenum fan motor, danger exists even after the input power has been
switched OFF. Do not directly touch the energized parts due to the
internal circuits remain energized for a short period of time after shutdown
or due to faults. The controller housing cover may only be opened when
the input power has been switched OFF and a period of three minutes has
elapsed since switching it OFF.
WARNING: The plug fan modules are powered by high voltage input line
power (i.e. 208-230V/3PH/60HZ or 460V/3PH/60HZ). Do not carry out
any work on electrically live parts. Even after disconnection, the de-link
circuit is still live. Always wait at least 3 minutes.
