1. Clean the opening of all debris that may interfere with installation. 2. Position the wall sleeve into the wall so that it is flush with the exterior wall. Important: If the wall sleeve has been installed into a thick wall, make certain the wall sleeve protrudes into the room a minimum of 1-1/8" (29mm) beyond the finished wall surface. This is to accommodate the heat section and room cabinet. The center of gravity is 10-3/4" (273mm) from the rear face of the standard wall sleeve.
CAUTION Do not drill holes in the base of the wall sleeve. Use shims between the wall and the wall sleeve to prevent wall sleeve distortion during anchoring. B 4" Wood Stool Brick Optional Continuous Flange Outside Louver Wall Sleeve 1' to 4" A heavy-gauge, corrosion resistant wall sleeve is provided for each unit. The wall sleeve is either shipped in a separate carton or shipped in a multi-pack of 15. Typical installation for masonry walls is shown in Figure 12.
Anchoring The Wall Sleeve IMPORTANT Anchoring the wall sleeve is accomplished as shown in Figure 14. Use the rubber isolation washers with the fasteners to minimize sound transmission from the equipment to the wall, at the point of contact. A 5⁄16" (8mm) hole is provided on each side, 2" (51mm) down from the top and 2" (51mm) in from the rear of the wall sleeve. It may be necessary to drill additional holes in the wall sleeve to firmly secure it.
CAUTION Do not pull on evaporator fan housing, control box or compressor. Do not lift by pulling on the tubing. Tubing can crack or bend damaging the unit. 4. If wall sleeve has been previously installed, remove temporary weather panel. 5. Check all fasteners to make certain they have not come loose during shipment. Do not loosen bolts holding down compressor; they are set at the factory. 6. Do not lubricate motors before start-up. Motors are permanently lubricated. 7.
Installing Room Cabinet The room cabinet is the last piece to install. The following instructions assume all components (wall sleeve, heat section, louver and chassis) have been installed, piped and anchored. All major room construction should also be complete so as not to damage the room cabinet after it has been installed. Attaching the room cabinet can be completed as follows: 1. Firmly grasp the room cabinet and lift it over the heat section.

Digital Control Board with Standby Power – Wiring Diagram The standby power connections, L1 STBY and L2 STBY are meant to run the indoor motor at a separate voltage from the other motors, compressor and outdoor motor. When used as such, the jumpers, JH1 and JH2, must be cut. This renders L1 & L2 and L1 STBY and L2 STBY isolated from each other. If there is no need to run the motors at a separate voltage the L1 = L1 STBY and L2 = L2 STBY. Therefore one voltage is used to run all motors.
Digital Control Board without Standby Power – Wiring Diagram The standby power connections, L1 STBY and L2 STBY are meant to run the indoormotor at a separate voltage from the other motors, compressor and outdoor motor. When used as such, the jumpers, JH1 and JH2, must be cut. This renders L1 & L2 and L1 STBY and L2 STBY isolated from each other. If there is no need to run the motors at a separate voltage the L1 = L1 STBY and L2 = L2 STBY. Therefore one voltage is used to run all motors.
Maintenance (Scheduled) Incremental conditioners are built to last. With proper care, the unit should provide uninterrupted service for many years. Scheduled maintenance of this equipment as described below, is the key to the equipment’s longevity. A. Air filters must be cleaned at regular intervals. Twice annually may be adequate in some areas while twice monthly may be required in others.
An inherent advantage of the Incremental system is that failure of any part affects only one incremental conditioner and does not interrupt the operation of the rest of the system. A further advantage is that a failed part can be quickly and easily replaced, thus minimizing the inoperative time of the equipment. This is so, however, only if a replacement part is quickly available.
