Service Clearances / Access Locations
APEX-200 units require minimum clearances for access on all sides for routine maintenance. Filter replacement,
drain pan inspection and cleaning, energy wheel cassette inspection, fan bearing lubrication and belt
adjustment, are examples of routine maintenance that must be performed. Blower and motor assemblies,
energy recovery wheel cassettes, coil and filter sections are always provided with a service door or panel for
proper component access. Clearances for component removal may be greater than the service clearances.
Contact Greenheck for component removal clearance.
