SYNERGY3D INSTALLATION MANUAL
Setting Vertical Units
Prior to setting the unit in place, remove and discard the
compressor hold down shipping bolt located at the front of
the compressor mounting bracket.
Vertical units are available in left or right hand return
configuration. Vertical units should be mounted level on
a vibration absorbing pad slightly larger than the base to
provide isolation between the unit and the floor. It is not
necessary to anchor the unit to the floor (See Vertical Unit
Mounting illustration).
Duct System
An air outlet collar is provided on vertical top flow units
to facilitate a duct connection, which is shipped inside the
unit. A flexible connector is recommended for discharge
and return air duct connections on metal duct systems.
Uninsulated duct should be insulated with a minimum of
1 in. duct insulation. Application of the unit to uninsulated
ductwork in an unconditioned space is not recommended
as the unit’s performance will be adversely affected.
If the unit is connected to existing ductwork, a previous
check should have been made to assure that the duct
has the capacity to handle the air required for the unit
application. If ducting is too small, as in the replacement of
heating only systems, larger ductwork should be installed.
All existing ductwork should be checked for leaks and
repaired when necessary
The duct system should be sized to handle the design
airflow quietly. To maximize sound attenuation of the unit
blower, the supply and return plenums should include inter-
nal duct liner of glass fiber or be of ductboard construction
for the first few feet. If air noise or excessive airflow is a
problem, the blower speed can be changed. See the Blower
Performance and Blower Speed sections.
Moving and Storage
Move units in the normal “Up” orientation. Vertical units
are not to be moved, but may be stored one upon another
to a maximum height of two units. When the equipment is
received, all items should be carefully checked against the
bill of lading to be sure all crates and cartons have been
received. Examine units for shipping damage, removing
the units from the packaging if necessary. Units in question
should also be internally inspected. If any damage is noted,
the carrier should make the proper notation on the delivery
receipt, acknowledging the damage.
Unit Location
Locate the unit in an indoor area that allows easy removal
of the filter and access panels, and has enough space
for service personnel to perform maintenance or repair.
Provide sufficient room to make water, electrical and duct
connection(s). If the unit is located in a confined space,
such as a closet, provisions must be made for return air
to freely enter the space by means of a louvered door,
etc. Care should be taken when units are located in
unconditioned spaces to prevent damage from frozen
water lines and excessive heat that could damage electrical
components.
Safety Considerations
Installation and servicing of heating and air conditioning
equipment can be hazardous due to system pressure and
electrical components. Only trained and qualified service
personnel should install, repair or service heating and air
conditioning equipment.
Untrained personnel can perform basic maintenance
functions of cleaning coils and cleaning and replacing
filters. All other operations should be performed by trained
service personnel. When working on air conditioning
equipment, observe precautions in the literature, tags and
labels attached to the unit and other safety precautions
that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for brazing operations. Have
fire extinguisher available for all brazing operations.
WARNING:
Before performing service or
maintenance operations on the system, turn off
main power switches to the unit. Turn off accessory
heater power switch if applicable. Electrical shock
could cause serious personal injury.
CAUTION:
A minimum of 24 in. clearance should
be allowed for access to front access panel.
