LX COMPACT SERIES INSTALLATION MANUAL
Installing and servicing heating and air conditioning equipment
can be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should install,
repair or service heating and air conditioning equipment. Untrained
personnel can perform the basic maintenance functions of clean-
ing coils and cleaning and replacing filters. All other operations
should be performed by trained service personnel. When working
on heating and 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
a quenching cloth for brazing operations and have a fire extin-
guisher available.
Moving and Storage
Move units in the normal “up” orientation. Horizontal units may
be moved and stored per the information on the packaging. Do
not stack more than three units in total height. Vertical units may
be stored one upon another to a maximum height of two units.
Do not attempt to move units while stacked. 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.
Safety Considerations
General Installation Information
WARNING: Before performing service or maintenance
operations on a system, turn off main power switches
to the indoor unit. If applicable, turn off the accessory
heater power switch. Electrical shock could cause
personal injury.
Vertical Unit Mounting
2 in. PEX Foam
Unit Location
Locate the unit in an indoor area that allows for easy removal of
the filter and access panels. Location should have 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. Any access panel screws that would be difficult
to remove after the unit is installed should be removed prior to
setting the unit. On horizontal units, allow adequate room below
the unit for a condensate drain trap and do not locate the unit
above supply piping. 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.
Installing Vertical Units
Vertical units are available in left or right air return configurations.
Top flow 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.
