ENVISION 2 COMPACT INSTALLATION MANUAL
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 work-
ing 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 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.
It is not necessary to anchor the unit to the floor (see
figure below).
