SECTION 2 – INSTALLATION
FORM 145.05-NOM7
ISSUE DATE: 10/31/2019
For installation, service and maintenance access, the
following clearances should be followed. Minimum
clearances required by local, state, or national codes,
such as NEC take precedence over those listed in Fig-
ure 1 on page 12. Clearance is required to allow
room for side filter access, mechanical cleaning of the
condenser tubes and water economizer coil, access to
expansion valves and other control components and
to allow for possible fan shaft or compressor removal.
Additional clearance should be considered for compo-
nent replacement such as condenser, evaporator, wa-
ter economizer coil and supply fan. Even though there
is no vertical clearance specification listed, clearance
above the unit may be an advantage during change out
of any of the above components.
