Service Clearances - Bosch FHP RT-20 Installation, Operation And Maintenance Manual

Service Clearances

RT-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 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 for these dimensions.
