6.1 Filters
Replaceable evaporator air filter(s) are supplied with the unit. The filter(s) are easily serviceable from
the outside, through the top front access panel.
Filters are usually the most neglected item in an environmental control system. To maintain efficient
operation, they should be checked monthly and changed as required. Units supplied with
Economizers may require replacement filters more frequently because of airborne dust and organic
materials.
Filters can be replaced from the front by opening the lower front access panel.
6.2 Blower Package
Periodic checks of the blower package include: blower wheels, housings, motor and motor mounting
bracket. With the power off, inspect and remove any debris from the wheels and housings. Also check
to see that they are tightly mounted on the motor shaft and rotate freely without rubbing against the
housing.
6.3 Economizer—Optional
Each month, the Economizer should be inspected and any debris removed from the intake hood,
damper blade and enthalpy sensor.
6.4 Heat
Heaters can be serviced and/or removed from inside through the discharge opening or from outside by
removing the top.
6.5 Refrigeration System
Each month, the components of the refrigeration system should be inspected for proper function and
signs of wear. Since, in most cases, evidence of malfunction is present prior to component failure,
periodic inspections can be a major factor in the prevention of most system failures.
