Energy Recovery Unit with Packaged DX
SERVICE CLEARANCES / ACCESS PANEL LOCATIONS FOR MODEL ERCH
Clearances must be maintained on all
sides of this unit . This especially is true
with the top of this unit . Hot air is being
discharged through the condensing
fans during operation, and the more
clearance available, the better the
chance of avoiding recirculation or coil
starvation . This unit should never be
placed under an overhang or inside a
building . A minimum of 48 inches over
the condensing fans is recommended .
ERCH-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 for these
dimensions .
