Remote/Wall-Mounted Debonair® Thermostat (24-v)

Step 4 — Make Duct Connections — Install all ductwork to and from unit in accordance with all applicable codes. Duct construction must allow unit to operate within duct external static pressure limits as shown on job submittals. Units designed to operate with ductwork may be damaged if operated without intended ductwork attached.

Units provided with outside air should have some method of low-temperature protection to prevent freeze-up.

Insulate ductwork as required. Use flexible connections to minimize duct-to-unit alignment problems and noise transmis- sion where specified.

Set unit markings for minimum clearance to combustible materials and first 3 ft of ductwork. Install ductwork, accessory grilles and plenums so that they do not restrict access to filter. Cut openings for supply-air and return-air grilles, thermostats and switch plates where specified on job drawings. Be careful not to cut wires, piping or structural supports. Use a steel ther- mostat shield ring to protect drywall from thermostat wiring where applicable.

CAUTION

Prevent dust and debris from settling in unit. If wall finish or color is to be spray applied, cover all openings to pre- vent spray from entering unit. Failure to do so could result in the reduction of unit efficiency.

Step 5 — Frame and Finish Unit — Models 42SG, SH and SJ have factory enclosures and may be finished with normally accepted wall covering. However, drywall secured with adhesive bonding alone is not recommended.

Use low-profile sheet metal panhead screws to secure wallboard to unit frame.

Do not apply sheet metal screw or nails where they can pen- etrate coil, riser pipes, or electrical junction box and raceways.

Do not secure wallboard to drain pan edges or to control box enclosure. Condensate leaks or electrical shorts may result.

An alternate method of enclosing the unit is to frame one or more sides with studding and apply the wall board to this fram- ing. This method requires specific unit features and return ac- cess panels when used on the return-air side of a unit. Units not properly equipped will exhibit poor cooling and/or heating per- formance and could experience excessive or premature compo- nent failures.

Prevent sheetrock dust or other debris from settling on coil fins, motor-blower assembly or other unit interior surfaces.

Return access and exposed cabinet units may be furnished with a baked enamel finish. Small scratches in this finish may be repaired with touch-up paint available from the factory. Some colors of touch-up paint are available in aerosol contain- ers and all touch-up paint is available in pint, quart, and gallon cans.

To repaint the factory-baked enamel, the finish should be prepared by light sanding with no. 280 grit sand paper or no. 000 or no. 0000 fine steel wool. The surface may also be wiped with a liquid surface etch cleaning product such as “No Sand” or “Pasceo.” These items should be available at most paint product stores. It should be noted that the more conscien- tiously this preparation is done, the more effective it will be.

After this preparation is accomplished, the factory finish should provide excellent adhesion for a variety of air-dried top coats. Enamel will give a more durable, higher gloss finish, while latex will not adhere as well and will give a dull, softer finish. Top coats involving an exothermic chemical process be- tween two components, such as epoxies and urethanes, should be avoided.

Factory aerosol touch-up paint may require a number of light “dust coats” to isolate the factory-baked enamel finish from the quick drying touch-up paint.
