REFRIGERANT PIPING CONNECTIONS
1. Follow steps 1 through 5 on the previous page to position piping
at the rear of the indoor unit. Before positioning the refrigerant
tubing permanently at the rear of the indoor unit, you must install
the conduit bracket.
Art Cool Premier indoor units require an additional conduit “bracket/
nut” to be installed at the rear. This allows the electrical connections
within the elbow (L-type) conduit (Figure 45) to be held in place at
the back of the unit.
2. Set the conduit wiring by using the bracket and “D” screws from
the accessory kit. This must be done prior to permanent place-
ment 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.
• See Figure 44 for a detailed view of the installation.
