GENERAL
The 40VMD multiport distribution controller (MDC) is a
distribution box for refrigerant to multiple indoor fan coil units
installed in a given heat recovery system.
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.
See Fig. 1 for model number nomenclature. Figure 2 shows
the unit dimensions. Table 1 lists physical data for each unit
size. Table 2 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
38VMAR outdoor unit.
