INTRODUCTION Use this instruction manual to install CC5A or CD5A/CD5P indoor coils on upflow or downflow furnaces. (See Fig. 1.) Do net install coil in horizontal position. Models CD5MCD5P are enclosed in a casing. Model CC5A is an unenclosed (bare) coil that requires a field-fabricated or accessory enclosure. IMPORTANT: Some coils are rotated 90 degrees. See Table 2 and Table 3 for lists of the sideways coils. INSTALLATION PROCEDURE 1--INSPECT EQUIPMENT File claim with shipper ff equipment is damaged or incomplete. PROCEDURE 2--SELECT INSTALLATION PROCEDURE For uncased coils (CC5A) follow: a. Upflow CC5A Uncased Coil Installation. See Table 3 for dimensions and accessory part numbers. For cased coils (CD5A) in upflow application follow: b. Upflow CD5A Cased Coil Installation. See Table 2 for dimensions and overhang options. Note instructions for placement of coil easing on furnace. For cased coils (CDSA) in downfiow application follow: c. Dowrdlow CD5A Cased Coil Installation. PROCEDURE 3---INSTALLATION a. Upflow CC5A Furuace OF FURNACE COILS Coil Installation (1.) Mount factory coil support (shipped with coil) directly on furnace flanges to support the coil. IMPORTANT: If uncased coil overhangs furnace refer to Table 1. If table indicates that coil mounting height is zero, use factory supplied coil supports. If table indicates that coil mounting height is other than zero, use field supplied coil supports, at specified height, and block off any bypass air as shown in Fig. 2. (2.) Slide coil into plenum opening. (3.) Cover plenum opening with field supplied front panel. (4.) When installing uncased coil into pro-installed -"> b. Upflow CDSAJCD5P Cased Coil Installation NOTE: accessory coil casing, use Table 3 to verify correct match. The cased coil is designed to fit furnaces of the same width and the next narrower size with no field fabricated adapters. (1.) Set coil in place on upfiow furnace discharge air opening. (2.) Ensure coil is level for proper condensate drainage. Do not tip coil toward condensate drain. Coil casing need not be fastened or screwed to furnace. (3.) When installing narrow coil on wide furnace, create field fabricated adapter. (See Fig. 3.) ---> c. Downflow CD5A/CD5P Cased Coil Installation IMPORTANT: Installing "A" coils rotated 90 degrees from the front of the furnace in downflow applications can cause water blowoff or coil freeze up. This is due to the concentration of air on one coil slab or lack of air on the opposite coil slab. If the airflow is high due to ductwork or other causes, and there is a chance for water blowoff, it is recommended that a 3-in. field-supplied adapter be placed between the coil and the furnace to allow the air to distribute evenly to both coil slabs. (See Fig. 5,) (1.) Set cased coil on supply duct opening. (2.) Place field fabricated 3 in. adapter on coil casing. Adapter should be tapered to fit coil/furnace combination the other. (See Fig. 5.) when one of them is larger than (3.) Set furnace on adapter. NOTE: In downflow instructions. installation with a 4-way multipoise furnace, break off perforated 2-- duct flanges on furnace. See furnace installation 12) (FIELD SUPPLIED) FURNACE A88576 Fig. 2--Adapter Installation When Field Fabricated Plenum Overhangs Furnace NOTE: When removing a coil from its casing in the downflow position, support the coil enclosure with field supplied bracing. (See Fig. 4.) PROCEDURE 4_CONNECT REFRIGERANT PIPING Use accessory tubing package or field-supplied tubing of refrigerant grade, see Product Data information for ordering. Suction tube must be insulated. Do not use damaged, dirty, or contaminated tubing because it may plug refrigerant flow-control device. ALWAYS evacuate the coil and field-supplied tubing before opening outdoor unit service valves. PROCEDURE 5--CONNECT For matched and mismatched REFRIGERANT, LIQUID, AND SUCTION LINES systems, use line sizes recommended in outdoor unit Installation Instructions. The coil can be connected to outdoor units using accessory tubing packages or field-supplied tubing of refrigerant grade. Always evacuate tubing and reclaim refrigerant when making connections or flaring tubing. Leak check connections before insulating entire suction line. Z_X CAUTION: To avoid valve damage to the refrigerant control device while brazing, service valves must be wrapped with a heat-sinking material such as a wet cloth. a. Suction Line Suction line is designed for field sweat comaection. Line is plugged to keep out moisture and dirt. Remove the plugs only when ready to make the connection. A_, CAUTION: is required. If unit is to be installed on system with a thermostatic expansion valve, removal of the indoor coil piston The following section applies to only the CC5A and CD5A coils: b, System Refrigerant Control A refrigerant control device (bypass type piston) is factory supplied with coil. (See Table 2 and Fig. 6.) The piston has a refrigerant metering hole through it, and is field replaceable. The piston shipped with the indoor coil may be different from the piston shipped with the outdoor condensing unit. If this is the case, you must replace the indoor piston. Always use the piston shipped with the outdoor condensing unit. c. Liquid Line (1.) Replace piston if required. Check the piston size stamped into side of brass hex nut. (See Fig. 73 If this piston number does not match required piston shown on outdoor unit rating plate, replace indoor piston with piston shipped with outdoor unit. (2.) When the piston is replace, hand tighten the brass hex nut, then tighten with wrench 1/2 turn. (3.) Remove rubber plug. (4.) Liquid line is designed for sweat connection. CAUTION: Remove Teflon seal during brazing. Replace when fitting has cooled. z_ CAUTION: DO NOT BURY MORE THAN 36 IN. OF REFRIGERANT TUBING IN GROUND. If any section of tubing is buried, there must be a 6 in. vertical rise to the valve connections on the outdoor unit. If more than the recommended length is buried, refrigerant may migrate to cooler buried section during extended periods of unit shutdown, causing refrigerant slugging and possible compressor damage at start-up. NOTE: Wrap a wet cloth around rear of fitting to prevent damage to factory-made --3-- joints. i MIN" FURNACE * CAUTION: Do not mount coil lower than 3 in. minimum or furnace failure may result, A00193 Fig. 3_Adapter Instaliation When Coil Casing Underhangs Furnace A02031 Fig. 4--Coil Enclosure Bracing DOWNFLOW FURNACE WITH ADAPTER WHEN REQUIRED f / A00192 Fig. 5--Downflow -- High Airflow Table 2----CD5A/CD5P Coil Information METERING TONNAGE MODEL NUMBER FITS NEXT SMALLER FURNACE DEVICE FLUSH NT Pis_n No TO FURNACE WIDTH (IN,) Equal Ove_g Fac_ Supplied TXV CDSAXA018014 I-1/2 52 14-3/16 CDSAXA024014 2 59 14-3/16 67 14-3/16 CDSAXW024017 2 59 17-1/2 X CD5AXW030017 2-112 67 17-1/2 X CDSAXA036017 3 70 17-1/2 X CDSAXW036021 3 70 21 X 78 21 X CD5AXA030014 2-1/2 CDSAXA042021 3 1/2 CD5AXA048021 4 84 CD5AXC048021 4 84 X *CDSAXW042024 3-1/2 78 24-1!2 X *CD5AXW048024 4 84 24-1/2 X *CD5AXA060024 5 90 24-1/2 X *CD5AXW060031 5 90 31 X *CDSPXX060024 5 -- 24-1/2 X 24-1/2 X 21 EA36YDI54 *Sideways Coils Table 3_CC5A Coil Information MODEL NUMBER TONNAGE METERING DEVICE PISTON NO.

Fig. 7--Refrigerant Control Device Components for CD5P A01446 NOTE: If unit is located in or above a living space where damage may result from condensate overflow, a field-supplied, external condensate pan should be installed under the entire unit, and a secondary condertsate line (with appropriate trap) should be rtm from the unit into the pan. Any condensate in this external condensate pan should be drained to a noticeable place. As an alternative to using an external condensate pan, some localities may allow the running of a separate 3/4 in. condensate line (with appropriate trap) per local code to a place where the condensate will be noticeable. The owner of the structure must be informed that when condensate flows from secondary drain or external condensate pan, the unit requires servicing or water damage will occur. NOTE: To avoid drainage problems, test the primary drain line by slowly pouring water into the pan. Check piping for leaks and proper condensate drainage. Using the secondary drain as explained in the previous note provides future protection against overflow due to a clogged primary drain. -Jo-- ENCLOSURE DRAIN 3" MIN t TO OPEN DRAIN OR SUMP Fig. 8--Condensate Trap A88571 --?-- O 2002 CAC/BDP 7310 w+ Mords St., IndianapOlis, IN 46231 imccSa09 --8-- Catalog No. 63CC-5A7
