ENVISION RESIDENTIAL INSTALLATION MANUAL
Moving and Storage
Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packag-
ing. 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.

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.

shipping bolt located at the front of the compressor mounting bracket.

power switches to the indoor unit. If applicable, turn off the accessory heater power switch.
Electrical shock could cause personal injury.
