Dectron DRY-O-TRON Supervisaire DSV 040 User Manual

Dectron, Inc. March 2012
DECTRON
Refer to AMCA
1
guidelines for system- effect considerations.
To prevent unexpected reduction of
airflow, allow a section of straight duct with
a length five times the blower width leaving
the DRY-O-TRON
®
. There should be no
elbows, transitions, offsets, duct heaters, or
other flow interruptions closer than
5 X the width of the blower outlet.
On special order, Dectron may be able to
provide bottom, top, or side discharge blowers.
See Product Description - Available Air Connections.
Minimum straight duct lengths still apply.
NOTE: On special order, Dectron may be able to offer reversed blower rotation.
NOTE: On special order, Dectron may be able to offer electric heaters that can be mounted on the blower outlet.
NOTE: Minimum straight supply-duct lengths are not required for units equipped with plenum blowers for
supply air.
See Installation - Ducts for more information.

NOTE: If used as natatorium dehumidifier, do not install a
DRY-O-TRON
®
dehumidifier in a return-air plenum
room. Corrosive chemicals in the air may shorten
the life of the electrical components.
NOTE: Poor return-duct design can prevent proper
dehumidification by causing uneven air distribution
over the evaporator. Reduced capacity and/or
equipment damage may result.
IMPORTANT!
Allow sufficient space for a straight length of full-sized
return duct as shown. This section of duct must have
the same width and height as the duct connection on the
unit. There should be no elbows, transitions, offsets, or
other flow interruptions closer than 2.5 X WIDTH of the
return duct opening.
If turning vanes are not used in elbows, allow a length
of straight duct equal to at least 5 X WIDTH.
NOTE: For DRY-O-TRON units with return plenum boxes, the minimum straight length for the
return duct is five times the lesser dimension of the return-duct connection. See
Product Description - Available Air Connections.
NOTE: High relative humidity can cause failure of the adhesive used in fibrous duct liner. If
such duct liner must be used inside a duct, use only water-resistant types.
NOTE: Do not install a duct heater in the return duct.
NOTE: Do not allow any air other than room air to enter the return duct. Do not
allow outdoor air or air mixed with outdoor air to enter the return duct.
