GENERAL

The 40VMF 4-way ceiling cassette effectively makes each area

served an independently controlled temperature zone. Through

thermostatic control of operations, conditions can be varied to

suit diverse requirements and activities.

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

model number nomenclature. Figure shows unit dimensions.

Table shows components that may or may not be used for a

particular installation.

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.
