2.1 UNIT INSPECTION
Upon receiving the unit, it should be inspected immediately for possible damage which may have occurred during
transit. If damage is evident, it should be noted on the carrier’s freight bill. A written request for in spection by the
carrier’s agent should be made at once.
2.2 LOCATION AND CLEARANCES
The following guidelines should be used to select a suitable location for the unit installation:
• Verify the floor or foundation is level. Failure to level the unit properly could result in condensate management
problems, such as stagnant water inside the unit.
• For installation, service and maintenance access, minimum clearances required by local, state, or national codes
should be followed. Clearance is required to allow room for filter access, mechanical cleaning of the condenser
tubes, access to expansion valves and other control components and to allow for possible fan shaft or compressor
removal. Additional clearance should be considered for component replacement such as condenser, evaporator 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.
