General Installation Information

Safety Considerations
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.
Installing and servicing 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 the basic maintenance functions of cleaning
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
extinguisher 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.
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
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 air return configurations.
Top air discharge 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 below).
If access to the left side of the unit will be limited after installation,
remove the two mounting screws on the left side of the control
box before setting the unit (leave the two front mounting screws
intact). This will allow the control box to be removed with only the
two front mounting screws for future service.
