1.0 SAFETY INFORMATION
WARNING
!
These instructions are intended as an aid to qualified licensed service person­nel for proper installation, adjustment and operation of this unit. Read these instructions thoroughly before attempting installation or operation. Failure to
ollow these instructions may result in improper installation, adjustment, serv-
f ice or maintenance possibly resulting in fire, electrical shock, property dam­age, personal injury or death.
WARNING
!
PROPOSITION 65: This appliance contains fiberglass insulation. Respirable particles of fiberglass are known to the State of California to cause cancer.
All manufacturer products meet current Federal OSHA Guidelines for safety. California Proposition 65 warnings are required for certain products, which are not covered by the OSHA standards.
California's Proposition 65 requires warnings for products sold in California that contain or produce any of over 600 listed chemicals known to the State of California to cause cancer or birth defects such as fiberglass insulation, lead in brass, and combustion products from natural gas.
All “new equipment” shipped for sale in California will have labels stating that the product contains and/or produces Proposition 65 chemicals. Although we have not changed our processes, having the same label on all our products facilitates manufacturing and shipping. We cannot always know “when, or if” products will be sold in the California market.
You may receive inquiries from customers about chemicals found in, or pro­duced by, some of our heating and air-conditioning equipment, or found in nat­ural gas used with some of our products. Listed below are those chemicals and substances commonly associated with similar equipment in our industry and other manufacturers.
• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO).
• Formaldehyde
• Benzene
More details are available at the websites for OSHA (Occupational Safety and Health Administration), at www.osha.gov (Office of Environmental Health Hazard Assessment), at www.oehha.org Consumer education is important since the chemicals and substances on the list are found in our daily lives. Most consumers are aware that products pres­ent safety and health risks, when improperly used, handled and maintained.
and the State of California’s OEHHA
.
CAUTION
For horizontal applications, the horizontal drain pan must be located under the indoor coil. Failure to place the pan under the coil can result in property dam­age.
CAUTION
It is recommended that an auxiliary/secondary drain pan be installed under units containing evaporator coils that are located in any area of a structure where damage to the building or building contents may occur as a result of an overflow of the coil drain pan or a stoppage in the primary condensate drain piping.

3.0 INSTALLATION
3.1 APPLICATIONS
(-)CF cased coils can be applied in upflow, downflow, horizontal right and horizontal left applications without modifications. (-)CF uncased coils can only be applied in upflow and
ownflow applications as received (see Table 2 and Figure 3). For horizontal applications
d of uncased replacement coils, installation of a horizontal drip shield and water manage­ment parts from old coil is required. (Also see Section 5.2: Horizontal Adapter Kit.)
For coils that are two sizes larger than the furnace, for example, a 21ⴖ wide coil on a 14ⴖ furnace, a tapered adaptor with a minimum height of 6ⴖ is required to evenly distribute airflow. See Figure 5. For coils that are one size larger than the furnace; for example a 21ⴖ wide coil on a 17 use the specified adapter kit (RXBA-AC). See Figure 6.
CAUTION
For horizontal applications, the horizontal drain pan must be located under the indoor coil. Failure to place the pan under the coil can result in property damage.

3.2 REFRIGERANT CONNECTIONS
Keep the coil connections sealed until refrigerant connections are to be made. See the Installation Instructions for the outdoor unit for details on line sizing, tubing installation, and charging information.
Coil is shipped with a low (5 - 10 PSIG) pressure charge of dry nitrogen. Evacuate the
ystem before charging with refrigerant.
s
Install refrigerant tubing so that it does not block service access to the front of the unit.
Nitrogen should flow through the refrigerant lines while brazing.
Use a brazing shield to protect the cabinet’s paint from being damaged by torch flames.
After the refrigerant connections are made, seal the gap around the connections with pressure sensitive gasket. If necessary, cut the gasket into two pieces for a better seal (See Figure 3.)
3.3 TEV SENSING BULB
IMPORTANT: DO NOT perform any soldering with the TEV bulb attached to any line.
After soldering operations have been completed, clamp the TEV bulb securely on the suction line at the 10 to 2 o’clock position with the strap provided in the parts bag.
Insulate the TEV sensing bulb and suction line with the provided pressure sensitive insu­lation (size 4” x 7”) and secure with provided wire ties.
IMPORTANT: TEV sensing bulb should be located on a horizontal section of copper suction line, just outside of coil box. The copper sensing bulb must never be placed on any aluminum tube as this will result in galvanic corrosion and eventual failure of the aluminum tube.

The RCF EXV equipped coils, cased and uncased, are the first Rheem indoor products
ULB

to be produced with the noncommunicating, stand-alone EXV control. One of the biggest advantages of an EXV is the control can intelligently change the EXV position based on system demands other than just suction line temperature. By the measurement of the suction pressure via the vapor line pressure transducer (factory installed) and the vapor line thermister (field connected to the vapor line, but factory provided within the air han­dler) the EcoNet™ enabled air handler control calculates the suction superheat at the indoor coil. This calculation permits the air handler control to make decisions for when to open and close the electronic expansion valve for the purpose of maintaining a predeter­mined suction superheat. The electronic valve is equipped with a 4-pole removable external stator, and inlet and outlet Chatleff fittings for optimal serviceability. These valves also have an internal check valve to provide heat pump compatibility. When oper­ating in heating mode, the air handler control will open the electronic valve completely to permit the check valve to operate and maximize reverse refrigerant flow.
3.5 EXV VAPOR LINE THERMISTER
IMPORTANT: DO NOT perform any brazing with the vapor line thermister attached to any line. After brazing operations have been completed, clamp the vapor line thermister securely on the vapor line at the 10 to 2 o’clock position with the clip provided on the thermister. Insulate the vapor line thermister and vapor line with the provided pressure sensitive insulation (size 4” x 7”) and secure with provided wire ties.
Make sure to protect the EXV pressure transducer, vapor thermister, copper to alu­minum joint, and service valves from overheating by use of wet rag or some type of shielding. Double tip torches are not recommended.
IMPORTANT: Vapor line thermister should be located on a horizontal section of vapor line, just outside of coil box. The copper thermister must never be placed on any aluminum tube as this will result in galvanic corrosion and eventual fail­ure of the aluminum tube.
IMPORTANT: Never place the thermister on the heat effected zone near the braze connection, but it should be located within 6” of the indoor unit.

3.8 EXV STEP DIP SWITCH
The EXV dip switch has an optional 500 or 1600 steps setting. This dipswitch should currently be in the 500 step position only. Rheem does not currently supply 1600 step EXV’s. The dipswitch makes the control forward compatible with a 1600 step EXV for possible future use.
3.9 DIAGNOSTICS
There are 2 LEDs (green/yellow) on the standalone EXV control which indicate valve movement. When the green LED is illuminated, the control is moving the valve in the open direction. When the yellow LED is illuminated, the control is moving the valve in the closed direction. When neither LED is illuminated, the valve is not being moved by the control. In addition to the diagnostic lights on the control, it is possible to feel the coil on the EXV pulse when the control is attempting to change the EXV position.

3.11 EXV STANDALONE CONTROL OPTIONAL MOUNTING
3.11 LOCATIONS
The EXV standalone control and housing is factory installed inside the case on the tube sheet. This location has been tested and approved for long term operation inside the highly humid environment. In the event servicing the EXV control without opening the coil door or to see the operational lights while the system is in operation the following alternate control and housing location is approved. The mounting location will require the wiring harnesses to be disconnected from the control, the control removed from the housing and the housing mounting screws removed. The wires will need to be routed through the knockout (there is one knockout per side) and then the assembly reassem­bled externally to the coil case.
IMPORTANT: It is recommended to place aluminum tape over the screw holes in the tube sheet to prevent bypass air.

3.13 FLOW CHECK PISTON
NOTICE
!
FOR PROPER SYSTEM OPERATION, IT MAY BE NECESSARY TO REPLACE THE PISTON INSTALLED IN THE INDOOR COIL. CHECK THE
ERVICE VALVES ON THIS UNIT TO SEE IF A NOTICE TAG ALONG WITH A
S PLASTIC BAG CONTAINING A PISTON IS ATTACHED. IF ONE IS PRESENT A CHANGE OF THE PISTON IS REQUIRED. FAILURE TO CHANGE THE PISTON CAN RESULT IN IMPROPER PERFORMANCE OF THE SYSTEM.
The flow check piston is a multi-purpose device. With flow into the compression nut end from the liquid line, the piston is in a check position and acts as the expansion device with flow through the metering orifice in the center of the piston. The “O” ring on the end of the piston prevents refrigerant from bypassing the metering orifice. Flow from the metering orifice is centered into a distributor which serves to evenly distribute refriger­ant to the evaporator circuits. With flow in the reverse direction (direction of arrows on the distributor body), the piston is forced off the seat and liquid from the condenser is allowed to free flow around the piston.
It is essential that the heat pump indoor and outdoor sections be properly matched. Use only matched components as shown in sales specification sheets.
A piston size that is too small will cause starving and one that is too large will cause flooding. In either case, system performance, reliability and charge balance (heating and cooling) will be unacceptable.
Change the piston in the distributor on the indoor coil before installing the coil and charging the system following the procedure below:
• Using a back-up wrench on the distributor body, loosen the compression nut to gain access to the piston.
• Using the wire provided with replacement pistons, run (hooked end) through hole in piston.
• Hook nose end of piston and lift gently from distributor body.
• Replace piston with one of proper size (see Table 4), install piston with gasket end of piston in distributor. Do not force piston into distributor.
• NOTE: With piston in distributor, seal end should be down and should not be seen looking in end of distributor. Piston must be free to rotate and move up and down. Make sure piston is free to move in distributor body.
• Insure distributor gasket is located properly in the distributor body.
• Replace compression nut using back-up wrench on distributor body. Torque compres­sion nut end with 8 to 10 ft. lbs.
FIGURE 14

• Original piston size is stamped on outside of distributor body. Remove new piston size label from poly bag new piston came in and install new size label on outside of distributor tube.
• Check fittings for leaks after installation, evacuation and charging is complete.
IMPORTANT: Do not attempt to drill pistons to size in the field. Metering holes have a special chamfered inlet and cannot be modified.
IMPORTANT: Do not replace the neoprene “O” ring on the piston with any type of seal.

IMPORTANT: When making drain fitting connections to the drain pan, use a thin layer of Teflon paste, silicone or Teflon tape and install hand tight.
IMPORTANT: When making drain fitting connections to drain pan, do not overtighten. Overtightening fittings can split pipe connections on the drain pan.
• Install drain lines so they do not block service access to front of the unit. Minimum
clearance of 24 inches is required for filter, coil or blower removal and service access.
• Make sure unit is level or pitched slightly toward primary drain connection so that
water will drain completely from the pan. (See Figure 15.)
• Do not reduce drain line size less than connection size provided on condensate drain
pan.
• All drain lines must be pitched downward away from the unit a minimum of 1/8” per
foot of line to ensure proper drainage.
• Do not connect condensate drain line to a closed or open sewer pipe. Run conden-
sate to an open drain or outdoors.
• The drain line should be insulated where necessary to prevent sweating and damage
due to condensate forming on the outside surface of the line.
• Make provisions for disconnecting and cleaning of the primary drain line should it
become necessary. Install a 3 in. trap in the primary drain line as close to the unit as possible. Make sure that the top of the trap is below connection to the drain pan to allow complete drainage of pan (See Figure 14).
• Auxiliary drain line should be run to a place where it will be noticeable if it becomes
operational. Occupant should be warned that a problem exists if water should begin running from the auxiliary drain line.
• Plug the unused drain connection with the plugs provided in the parts bag, using a
thin layer of teflon paste, silicone or teflon tape to form a water tight seal.
• Test condensate drain pan and drain line after installation is complete. Pour water into
drain pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no leaks are found in drain line fittings, and water is draining from the ter­mination of the primary drain line.

3.15 DUCT FLANGES
Field-installed duct flanges (4 pieces) are shipped with units. Install duct flanges as needed on top or bottom of the coil casing. (See Figure 16.)
CAUTION
It is recommended that an auxiliary/secondary drain pan be installed under units containing evaporator coils that are located in any area of a structure where damage to the building or building contents may occur as a result of an overflow of the coil drain pan or a stoppage in the primary condensate drain piping.
3.16 COIL END SHIELDS
All uncased replacement coils come equipped from the factory with sheet metal shields at the front and rear of the coil. The purpose of these shields is to isolate the aluminum tubing from copper residue left on the foil insulation by the original copper tube coil. Copper residue or copper oxide in contact with the aluminum tubing in the presence of moisture will result in galvanic corrosion and leaks in the aluminum tube at the contact point. The shields must be in place on the coil when replacing a copper tube coil to pre­vent the galvanic corrosion.
4.0 MAINTENANCE
WARNING
!
These instructions are intended as an aid to qualified licensed service person­nel for proper installation, adjustment and operation of this unit. Read these instructions thoroughly before attempting installation or operation. Failure to follow these instructions may result in improper installation, adjustment, service or maintenance possibly resulting in fire, electrical shock, property damage, personal injury or death.
For continuing high performance and to minimize possible equipment failure, it is essen­tial that annual maintenance be performed on this equipment. Consult your local dealer as to the availability of a maintenance contract.
4.1 AIR FILTER
Check the system filter every ninety days or as often as found to be necessary and if obstructed, clean or replace at once.
IMPORTANT: Do not operate the system without a filter in place.
4.2 INDOOR COIL - DRAIN PAN - DRAIN LINE
Inspect the indoor coil once each year for cleanliness and clean as necessary. In some cases, it may be necessary to remove the filter and check the return side of the coil with a mirror and flashlight.
IMPORTANT: Do not use caustic household drain cleaners or bleach in the condensate pan or near the indoor coil. Drain cleaners will quickly damage the indoor coil.
