Figure 2: Louver frame dimensions WARNING Residential and institutional cleaning compounds can cause permanent damage to the packaged terminal unit. To avoid damage to unit controls and heat transfer surfaces, do not spray cleaning compounds onto the discharge grille, return air opening, or unit controls. Normal cleaning can be accomplished by wiping the unit surface with a damp cloth.
Wall Construction Types CAUTION Figure 4: Panel wall (thin) construction 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. Steel Studs Note: Concrete Pillars When using recessed louver wall sleeve, level and plumb wall sleeve using the top and sides of the sleeve and the chassis slide rails. DO NOT level using the bottom of the wall sleeve as it has a built in pitch to drain. Installing Louvers 1.
Applications utilizing field supplied louvers require additional considerations: 1. Louvers supplied by others must have 70% free area or a pressure drop not exceeding 0.05 in. w.g. (12.45 Pa) at 300 fpm (1.524 m/sec) face velocity, and a blade design that will not cause recirculation of air. 2. Daikin does not warrant the rain and water leakage resistance of its equipment when used with louvers by others. 3. All louvers by others must be approved by Daikin engineering prior to installation.
Figure 9: 16" x 42" optional recessed louver wall sleeve with continuous flange and drip edge X* Flange location (from outdoor side of sleeve) is factory provided in increments of 1/8" D** 42" Flange Height (Standard = 1-1/4") 16" Louver Mounting Holes Drip Edge Notes: 1. Caulk entire perimeter of wall sleeve after installation. 2. Seal area between louver and wall sleeve to prevent condenser air recirculation. ** See "Table 1: Cabinet & wall sleeve dimensions" on page 5 for dimension "D".
Thick Wall Construction 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 11. The recommended installation procedure for this type of construction is as follows: 1. Clean the opening of all debris that may interfere with installation. 2. Be sure the unit’s center of gravity falls within the load bearing surface of the wall.
Figure 13: Anchoring the wall sleeve Anchoring The Wall Sleeve 7. Anchoring the wall sleeve is accomplished as shown in Figure 13. 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.

Installing The Valve Prior to soldering the normally closed two-way valve, open the ports by slowly moving the manual operating lever to the retaining notch until lever is secured by valve spring. The lever will reset to the automatic position the first time the valve is energized. Note: When installing two-way valves, the flow direction is from end “B” as shown in Figure 18.

Installing Cooling Chassis Correct installation of the cooling chassis is extremely important to insure the proper operation of the unit. Install the chassis as follows: 11. Slide chassis into wall sleeve until firmly seated against weather seals of wall sleeve. Figure 28: Slide chassis into wall sleeve 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. 1. 2. 3. 4. 5. 6.

Operating Instructions Cooling or Heating – Manual Operation The PGAN unit controller has built-in features such as random start, compressor time delay, night setback, load shed, shutdown. The 24 volt low voltage terminal strip is set so R-G energizes the fan. R-W1 energizes the fan and compressor. User Controls A 4 button touch key pad, with a High/Low Fan speed and Auto/On Switch located behind the control door, controls both temperature and operation mode.

Monthly Maintenance and Cleaning Intake Air Filters To properly maintain the operational performance of your PTAC unit, it is extremely important that the inlet air filters be cleaned once per month or more often if operated in dusty or dirty locations or conditions. The intake air filters are constructed of durable polypropylene. The “air intake” air filters can be easily inserted into the cabinet front using the cabinet filter guides.
