CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these
procedures may result in damage to equipment. For
information about replacement oil type and viscosity, see
the Installation, Start-Up, and Service Instructions for the
38VMAH and 38VMAR outdoor units.

GENERAL

The 40VMU under ceiling/floor unit can be installed exposed
at the ceiling or mounted on the wall close to the floor. It is
ideal for corner or low-ceiling areas where soffit space is not
available for furred-in units.
The equipment is initially protected under the manufacturer's
standard warranty; however, the warranty is provided under the
condition that the steps outlined in this manual for initial
inspection, proper installation, regular periodic maintenance,
and everyday operation of the unit be followed in detail. This
manual should be fully reviewed in advance before initial
installation, start-up and any maintenance. Contact your local
sales representative or the factory with any questions BEFORE
proceeding.
Table 1 lists physical data for each unit size. See Fig. 1 for the
