REFRIGERANT PIPING CONNECTIONS
1. Follow steps 1 through 6 on the previous page to connect piping
to the rear of the indoor unit.
HV3, HEV and HXV single-zone models require an additional conduit
“bracket/nut” to be installed at the rear of the indoor unit. Follow the
steps below for correct placement for your unit model.
2. Set the conduit by using the bracket and “D” screws from the
accessory kit. This must be done prior to permanent placement
of the piping to the rear of the unit, otherwise you won’t be able
to reach the conduit once piping and drain hose are in place and
anchored.
• For specific bracket placement, see each figure relating to the
specific single-zone model.
