When outdoor air is added, make certain that it is far enough ahead of the air cleaner to be mixed and warmed properly. If not, baffles must be installed to force mixing of the air. 2. Preheat coil. If a large amount of outdoor air is used, it must be heated. A thermostat should be used to control the heater. (A strip heater or hot water coil are typical heaters.) INSTALLATION PROCEDURE Remove Filter and Clean Blower Compartment Before Starting Installation. 1. Remove and discard the old filter if one is used. 2. Thoroughly clean the blower compartment. The air cleaner cannot remove dirt from the blower compartment or distribution ducts. Installation of 31MP Plate-Type or 31 MM Media-Type Air Cleaner 1. Remove power door by turning fastener knob, Fig. 2, item 5, counterclockwise until power door is free. Slide out prefilter and air cleaner cells. 1 — Cabinet 2 - Collector Cell (31 MP) 3 — Prefilter 4 — Power Door 5 — Fastener Knob 6 — Test Button Fig. 2 — Electronic Air Cleaner Components, Model 31 MP 2. Unit can be installed with air flow thru the cabinet in either direction. No changes to the cabinet are necessary when reversing the air flow direction thru air cleaner. See Fig. 3. 3. Apply template, supplied in package, to side of furnace and prepare the opening in side of furnace according to instructions on template. 4. Prepare return air duct for installation of unit. Allow a minimum of 30-in. clearance in front of power door for servicing. 5. Return air duct should use full cabinet opening. Run duct straight into unit. Use an elbow with turning vanes if duct takes a sharp turn close to air cleaner inlet. Do not baffle off any portion of entering air side of air cleaner When it is necessary to change duct size close to the air cleaner, use gradual transitions to reduce turbulence.

When installing unit at bottom return opening of an upflow furnace: a. Center furnace on air cleaner cabinet and remove components from cabinet. b. Field-fabricated support not required on Carrier furnaces. c. When the furnace is larger or smaller than the air cleaner, baffle off any mismatch between furnace and air cleaner with baffles, included with unit. Additional support, such as support legs, is recommended when furnace overhangs the air cleaner. pravafit % cormr from siipplnsg down ajkS 7. If a filter flag is used to indicate a clogged filter, install it downstream of cleaner, following instructions furnished with the filter flag. 8. Seal all joints on downstream side of air cleaner. 9. Slide prefilter and air cleaner cells into cabinet. Units are shipped for right-hand installation. To convert from a right- to a left-hand unit, reverse the position of the prefilter and the air cleaner cells in the cabinet as indicated in Fig. 3. Be sure the air flow arrows are pointing to the direction of air flow thru unit, and the ionizer wires in the cell are adjacent to the prefilter. The 31MC220 high-efficiency mechanical filter does not have a prefilter or electronic cell. Simply reverse position of filter element to change from right- to left-hand. An air flow direction arrow is stamped on the filter element. 10. Remove junction box cover on 31 MM and MP units only, Fig. 5, item 1, located below receptacle, item 2, on top inside of cabinet. Install strain relief in opening for 120-volt input supply, Fig. 2, item 10, in top of cabinet. Connect 120-volt supply pigtails in junction box with wire nuts provided, and connect ground wire to green pigtail provided. Wire supply voltage from fan circuit of system to have air cleaner operating only when unit fan is running. See Fig. 6, 7, 8 and 9 for typical furnace wiring diagrams. All wiring must comply with applicable local and national codes. 11. Replace power door. Turn fastener knob clockwise until power door is securely fastened, thus ensuring good electrical contact between power door and unit components. Diverse installations are shown in Fig. 12. 12. Check over the installation for correct sheet metal and electrical work. 3 4 — Contact Spring (Contactor) 5 — Cabinet 6 — Screw for Holding Top Guide NOTE...
