Handling

While this unit was constructed with quality and
dependability in mind, damage still may occur during
handling of the unit for installation. Exercise extreme
caution to prevent any damage from occurring to the
refrigerant system.

The system design and installation should follow
accepted industry practice, such as described in
the ASHRAE Handbook. Adequate space should
be left around the unit for filter replacement and
maintenance. Sufficient space should be provided on
the side of the unit for routine service and component
removal should that become necessary.
