Do not install coil in horizontal position. Coils are enclosed in a painted casing have factory-installed TXV's. These coils are used with R-410A refrigerant systems. NOTE: Models with tin-plated copper coils, "T" in the 8th position of the model number, are installed the same as standard copper coils. INSTALLATION Select These units can be installed in multiple configurations. Before installation, there are several performance requirements that must be considered because poor installation can negatively alter performance. This section wilt briefly discuss those factors. Airflow Airflow amount and distribution are vital to adequate system performance. Problems that can be experienced with incorrect airflow include: • low system performance • restricted TXV frosted coil poor humidity control water blow-off When attaching the coil and building the plenum, pay special attention to the effect these details will have on airflow. After system start-up, check the cfm to insure that it is correct. (Generally, the cfm should be 350 to 400 cfm/ton during normal cooling operation.) TXV A thermal expansion valve is utilized in this coil design to optimize performance and comfort throughout the entire operating range of the system. Special attention needs to be taken to the TXV when installing the coil Do not overheat valve. Temperatures that exceed 212°F Installation Procedure PROPERTY DAMAGE HAZARD Failure to follow damage. this caution may result in property installing coils rotated 90 ° from the front of the furnace, in upflow or downflow applications, may cause water blow-off or coil freeze-up due to the concentration of air on one slab of the coil or lack of air to a stab in the coil. it is recommended that on this type of application, a field-supplied adapter be placed between the coil and furnace to allow air to distribute properly between all slabs of the coil. NOTE: Furnace coils are not approved to be used in fan coil or "draw-through" type applications. To install cased coils in upflow applications, follow the instructions below, Upflow Cased Coil Installation. To install cased coils in downflow applications, follow the instructions below, Downflow Cased Coil installation. See Table 1 for dimensions and overhang options. Refer to instructions for placement of coil casing on furnace. (100_}0) can harm valve performance. Use a wet cloth or heat sink when brazing. Place liquid filter dryer near ID unit to reduce the risk of debris clogging the valve. Make sure TXV bulb is securely fastened and wrapped in the indentation on vapor line tube. END4X, ENW4X coils have a factory-installed hard-shutoff TXV designed only for use with R-410A refrigerant. Use only with outdoor units designed for R-410A. NOTE: AIt TXV'S have preset superheat not field-adjustable. settings and are Cabinet Sweating if this unit is installed in a garage, attic, or other unconditioned space, special attention needs to be given to the potential of cabinet sweating. A 6-in (152 mm) wide piece of insulation should be wrapped around the coil casing and supply duct connection point.

UNiT DAMAGE HAZARD Failure to follow damage. this caution may result in product To avoid valve damage to the refrigerant control device while brazing, valves must be wrapped with a heat_ial such as a wet cloth. 1. Remove cabinet access door. 2. Remove rubber plugs from coil stubs using a pulling and twisting motion. Hold coil stubs steady to avoid bending or distorting. 3. Wrap TXV and nearby tubing material such as a wet cloth. with a heat sinking 4. Use 1/2 psig Nitrogen purge in the suction and out the liquid line. 5. Braze using a Sil-Fos use soft solder. 484 01 3600 00 or Phos-copper alloy. Do not Device END4X, ENW4X coils have a factory-installed hard shut-off TXV designed only for use with R-410A refrigerant. Use only with outdoor units designed for R-410A. NOTE: ALL TXV'S HAVE PRESET SUPERHEAT SETTINGS AND ARE NOT FIELD-ADJUSTABLE. this caution may result in property When installing over a finished ceiling and/or living area, install a field-fabricated secondary condensate pan under the entire unit. The coil is designed to dispose of accumulated water through built-in condensate drain fittings. It is recommended that PVC fittings be used on the condensate pan. Do not over-tighten. Finger tighten plus 1-1/2 turns. Be sure to install plastic plug in unused condensate drain fitting. Two 3/4 inch female threaded pipe connections are provided in each coil condensate pan. A trap is not necessary on the condensate line. Consult local codes for additional restrictions or precautions. If local codes require a trap then the following guidelines are suggested to assure proper drainage. Install a trap in condensate line of coil as close to the coil as possible. Make trap at least 3 inches (76 mm) deep and no higher than the bottom of unit condensate drain opening (See Figure 6). 5 Pitch condensate line 1 inch (25.4 mm) for every 10 ft. of length to an open drain or sump. Make sure that the outlet of each trap is below its connection to condensate pan to prevent condensate from overflowing the drain pan. Prime all traps, test for leaks, and insulate traps and lines if located above a living area. EXPLOSION HAZARD Failure to follow this warning could result in personal injury or death. Provide trap with air gap in drain line when connecting to waste (sewer) line. Humidifier Application When installing a humidifier in a system which contains an N-coil, consideration must be given to location of coil slabs. See Fig. 8. 1. The humidifier should be mounted to the supply plenum or return duct whenever possible. If necessary, humidifiers can be mounted to the left side of coil casing. The right side of the coil casing must not be used to mount the humidifier. A08067X Figure 6 - Condensate Trap 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 underneath the entire unit, and a secondary condensate line (with appropriate trap) should be run 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 inch (19 mm) 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. To further protect against water damage, install a float switch to shut the unit off if the water in the secondary pan gets too high. 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 further protection against overflow due to a clogged primary drain. 2. Care must be taken to prevent damage of N-coil when attaching humidifier to coil casing or plenum. 3. Ensure that humidifier has adequate airflow. Evaporator N-Coil Upflow Furnace NOTE: In applications where return air humidity levels stay at 70% or above for a prolonged period of time, condensation can form on the bottom of pan and drip. WASTE A05414 Figure 8 - Installation LINE CONNECTION If the condensate line is to be connected to a waste (sewer) line, an open trap must be installed ahead of the waste line to prevent escape of sewer gases (See Figure 7). of Humidifier in System with N=Coil Air Gap Above aid Level Condensate Line Trap I Sewer Line I A102t6 Figure 7 - Condensate 6 Drain to Waste Line 484 01 3600 00 ii Digit Position 1 2 3 4 5 6,7 8 9,10 11 12 E N D 4 X 18 C 14 A 1 E = Evaporator B = Builder D = Standard N = N Coil TYPE A = Uncased D = Cased Upflow/Downflow M = Cased Multiposition (Upflow/Downflow/Horizontal) W = Cased Upflow/Downflow H = Cased Horizontal 4 = Environmentally for narrower furnaces INSTALLATION Sound R-410A P = Piston X = TXV REFRIGERANT METERING DEVICE 18 = 18,000 BTUH = 11/2tons 19 = 18,000 BTUH = 11/2tons 24 = 24,000 BTUH = 2 tons 30 = 30,000 BTUH = 21/2tons 31 = 30,000 BTUH = 21/2tons 36 = 36,000 BTUH = 3 tons 37 = 36,000 BTUH = 3 tons 42 = 42,000 BTUH = 31/2tons 43 = 42,000 BTUH = 31/2tons 48 = 48,000 BTUH = 4 tons 60 = 60,000 BTUH = 5 tons 61 = 60,000 BTUH = 5 tons NOMINAL CAPACITY C = Plain Copper L = Aluminum T = Tin Coated Copper 14 = 14.5" HAIRPIN MATERIAL 17 = 17.5" 21 = 21" 24 = 24.5" BB = 15.5" FF = 19.1" JJ = 22.8" LL = 24.5" WIDTH Sales Digit (Major Revision) Engineering Digit (Minor Revision) 484 01 3600 00 International Comfort Products, LLC Lewisburg, TN 37091 USA 7
