Wall Opening Requirements When roughing in the opening for the wall sleeve, make certain there is sufficient clearance from the walls and floor. The wall sleeve should be positioned a minimum of 5/8" in from the room side finished wall to accommodate the room cabinet. A minimum distance of 3" above the finished floor is required for return air. The rough opening should measure 16-1/4" high x 42-1/4" wide. When using a louver frame, the opening must measure 16-5/8" x 42-5/8".
3. Insert leveling bolts into subbase bottom flange. Four (4) bolts are required if side extensions are used. Only two (2) bolts are required if side extensions are not used. 4. Place the subbase on the floor and align its center line with the center line of the wall opening. Do not fasten the subbase to the floor. Attach the subbase to the wall sleeve using the clips provided with the subbase. 5. The wiring should be roughed in and the conduit connected to the subbase junction box.
Notes: 1. Side channels are adjustable from 0" to 9-3/8" in length by inverting them. Side channels are predrilled to allow infinite adjustment. 2. Subbase shown with louvered front panel removed. Front panel is hinged to allow access to valve, coil, filter & electrical junction box. 3. Leveling legs are adjustable from 1/4" to 1-1/4". Hydronic Subbase A subbase is available as required with all hydronic units. This subbase measures 8" (203mm) in height and includes the hydronic heating coil.
Electrical The electrical supply can also be roughed in to the subbase heat section either through the holes provided in the base or through the back. The receptacle is shipped in a separate carton to be field installed in the knockout provided, and wired in the junction box. Complete the installation as described below: 1. Remove the junction box cover plate. 2. Punch out the desired electrical knockout and connect the electrical supply conduit. 3. Connect power supply wires to the receptacle.
3. Drill two (2) 5/32" pilot holes for the mounting screws. These holes can be located using the drain kit as a pattern. 4. Assemble the drain kit as shown in Figure 11 and securely fasten it to the wall sleeve with the screws provided. Use either the 90o elbow or 6" straight fitting as required. 5. Install the wall sleeve by referring to the instructions, "Installing Wall Sleeve" on page 12. Installing Condensate Drain Kit(s) External Drain Kit Indoor Drain Kit Alternate 6" Long, 1/2" O.D.

Installing Wall Sleeve Considerations The wall sleeve is a standard size 16" high, 42" wide and 133/4" deep.
Installing Wall Sleeve Extension Wall sleeve extensions are shipped in a separate carton and tagged to match the proper unit. Be sure to check tagging of the extension against that of the unit. Install the wall sleeve extension as follows: 1. Position the extension with standard wall sleeve so proper alignment with drain and mounting holes is achieved. 2.
Procedure Anchoring The Wall Sleeve 1. Clean the opening of all debris that may interfere with installation. 2. If the unit is to be supplied with a subbase, install subbase before installing wall sleeve. See IM 937 for Electric Subbase Installation details and IM 936-x for the Hydronic Heat Section Installation details. 3. lf the optional drain kit is to be employed, see "Installing Condensate Drain Kit(s)" on page 11. 4.
Installing Basic Wall Sleeve Figure 17: Frame and brick with electrical subbase Steel Lintel (by others) Frame and Brick Wall Construction Type 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 multipack of 15. The basic wall sleeve is designed to be easily installed in a variety of wall constructions. Note: The center of gravity is 10" (254mm) from the rear face of the wall sleeve.

Attaching Wall Sleeve to Subbase 1. Where a subbase is used, secure wall sleeve to subbase with clips provided. 2. Caulk the wall sleeve to the wall opening on both the inside and outside perimeter. Be careful not to plug the weep holes. Caulking should be resilient, nonhardening type such as silicone. 3. Secure the two sections by installing the clip screws supplied with the hardware bag. 4. Caulk indoor/outdoor perimeter of wall sleeve with resilient caulk such as silicone. 5.
Installing Louver(s) 1. Remove louver and mounting hardware from the shipping carton. 2. Remove temporary cardboard weather panel from wall sleeve. 3. Make a temporary handle by looping a piece of flexible wire or heavy cord through the louver. This enables the installer to keep a firm grasp on the louver when installing from inside the room. 4.
Equipment Start-up Initial start-up of the Incremental® conditioners by experienced personnel is usually the responsibility of the installing contractor. This start-up consist of inspecting and operating the equipment for all functions at the time of initial installation and making necessary adjustments. It also includes demonstrating its proper operation to the owner or his agent, by their signature at the bottom of Form No.

Operation Memory Recall The digital control shall start with the last settings used prior to power down. These settings are saved in a non-volatile memory. Factory set mode is OFF. On/Off Triggering Control can be turned On/Off via LUI, Remote T’stat, or Sleep feature. The control will show the temperature set point when the mode is Cool, Cool Dry, or Heat. The display will be blank in Fan mode. 1. On/Off triggering with LUI Control shall turn On or Off when the On/Off button is pressed in LUI.
Control Lockout Feature The control is placed in a lockout mode of operation when Mode button is held pressed for 10 seconds. Display will show “LC” to confirm Lockout Mode has been entered. Once in this Lockout Mode the control board will not take any commands at all. In Lockout, unit will continue to operate with the same settings just prior to Lockout Mode. This means the touchpad will no longer be able to pass commands to the control. User’s set point will normally be displayed.

Place jumper across 10, 20, 30, or 1 HR to select fan cycle off minutes which will be overridden by the room temperature.
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) Equipment Protection From The 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. Environment 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.
