SERVICE CLEARANCES / access panel locations

HRE-20, 45, 55, and 90 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 cassette, 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, refer to drawings below for these dimensions.
