2. Quick Reference Guide For R-410A • R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R- 22. Ensure that servicing equipment is designed to operate with R-410A. • R-410A refrigerant cylinders are pink. • R-410A, as with other HFC’s is only compatible with POE oils. •...
of times consecutively, pause and then repeat the process. To identify a Flash Code number, count the number of consecutive flashes. IMPORTANT: Every time the module powers up, the last ALERT Flash Code that occurred prior to shut down is displayed for one minute. The module will continue to display the flash code until the condition returns to normal or if 24VAC power is removed from the module.

The Comfort Alert diagnostics module diagnoses system and electrical problems in the air conditioning system. Abnormal conditions are indicated by flashing ALERT codes on the yellow LED on the Comfort Alert module. The flash codes are transmitted to the thermostat when the terminal on the Comfort Alert Module is connected to the terminal on the thermostat.

3) Flash Code 4 - Locked Rotor Condition: The compressor internal overload trips where the average run time is less than 15 seconds. Possible causes: Bad run capacitor Low line voltage Excessive liquid refrigerant in compressor Compressor bearings are seized Faulty hard start components Active Thermostat Reaction: The thermostat implements a hard lockout once this error is sensed.

VI. INSTALLATION A. GENERAL 1. PRE-INSTALLATION CHECK-POINTS — Before attempting any installation, care- fully consider the following points: Structural strength of supporting members (Rooftop Installation) Clearances and provision for servicing Power supply and wiring Gas supply and piping Air duct connections and sizing Drain facilities and connections Location for minimum noise and vibration 2.
FIGURE 5 OUTSIDE SLAB INSTALLATION. CLOSET DISTRIBUTION SYSTEM. SLAB FLOOR CONSTRUCTION 2. Provide a slab sufficiently high enough above grade to prevent surface water from entering the unit. Where snowfall is anticipated, mount the unit above the anticipat- ed maximum snow depth for your area. Do not locate unit in an area where exces- sive snow drifting may block combustion air inlet.

FIGURE 16 PITCHED ROOFTOP INSTALLATION, ON ROOFJACK, DOWNFLOW DUCTWORK, ATTIC OR DROP CEILING DISTRIBUTING SYSTEM. PITCH UNIT TOWARD DRAIN. Place the unit as close to the conditioned space as possible allowing clearances as indi- cated. Run ducts as directly as possible to supply and return outlets. Use of non-flam- mable weatherproof flexible connectors on both supply and return connections at unit to reduce noise transmission is recommended.
FIGURE 17 LIFTING DETAIL. . FILTERS The installer must install field supplied filters in the return air duct. A field installed filter grille is recommended for easy and convenient access to the filters for periodic inspec- tion and cleaning. Filters must have adequate face area for the rated air quantity of the unit.
VII. GAS SUPPLY, CONDENSATE DRAIN AND VIII. PIPING A. GAS CONNECTION IMPORTANT: Connect this unit only to gas supplied by a commercial utility. 1. Install gas piping in accordance with local codes and regulations of the local utility company. In the absence of local codes, the installation must conform to the specifi- cations of the National Fuel Gas Code, ANSI Z223.1 - latest edition.
TO CHECK FOR GAS LEAKS, USE A SOAP AND WATER SOLUTION OR OTHER APPROVED METHOD. DO NOT USE AN OPEN FLAME. WARNING DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS. THE USE OF AN OPEN FLAME CAN RESULT IN FIRE, EXPLOSION, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
C. NOx MODELS When converting units equipped with NOx inserts to LP gas, the stainless steel mesh inserts in the entrance of the tubular exchangers are not required to meet SCAQMD NOx emission levels. Carefully remove these inserts before firing this furnace on LP gas. This furnace is not designed to operate on LP gas with the NOx inserts in place.

1. All wiring should be made in accordance with the National Electrical Code. Consult the local power company to determine the availability of sufficient power to operate the unit. Check the voltage at power supply to make sure it corresponds to the unit’s RATED VOLTAGE REQUIREMENT.
Refer to instructions packed with the thermostat for “heater” selection or adjustment. Refer to the RRNL-/RRPL-/RRRL- Specification Sheets for a list of recommended ther- mostats.
TABLE 6 TABLE 6 FIELD WIRE SIZE FOR 24 VOLT THERMOSTAT CIRCUITS SOLID COPPER WIRE - AWG. Length of Run – Feet (1) (1) The total wire length is the distance from the furnace to the thermostat and back to the furnace. NOTE: DO NOT USE CONTROL WIRING SMALLER THAN NO.
If the control detects the following failures, the LED will flash on for approximately 1/4 sec- ond, then off for 3/4 second for designated failure detections. 1 Flash: Failed to detect flame within the three tries for ignition. 2 Flash: Pressure switch or induced draft blower problem detected. 3 Flash: High limit or auxiliary limit open.
WARNING THE SPARK IGNITOR AND IGNITION LEAD FROM THE IGNITION CONTROL ARE HIGH VOLTAGE. KEEP HANDS OR TOOLS AWAY TO PREVENT ELEC- TRICAL SHOCK. SHUT OFF ELECTRICAL POWER BEFORE SERVICING ANY OF THE CONTROLS. FAILURE TO ADHERE TO THIS WARNING CAN RESULT IN PERSONAL INJURY OR DEATH.
4. Avoid excessive use of exhaust fans. 5. Do not permit the heat generated by television, lamps or radios to influence the ther- mostat operation. 6. Except for the mounting platform, keep all combustible articles three feet from the unit and exhaust system.
WARNING DISCONNECT MAIN ELECTRICAL POWER TO THE UNIT BEFORE ATTEMPT- ING MAINTENANCE. FAILURE TO DO SO MAY RESULT IN ELECTRICAL SHOCK OR SEVERE PERSONAL INJURY OR DEATH. C. LUBRICATION IMPORTANT: DO NOT attempt to lubricate the bearings on the blower motor or the induced draft blower motor.
Contact your local distributor for a complete parts list. F. CHARGING Refer to the appropriate charge chart included in this manual. G.

B. TRANSFORMER PROTECTION The ECM interface board is equipped with an automotive-style 3 amp ATC blade fuse for transformer protection. (See Figure 28.) If a short circuit occurs on the secondary side of the transformer, the fuse will open. C. USING THE ON-BOARD LED TO DETERMINE BLOWER CFM The ECM interface board LED, which is located in the blower section (see Figure 28), indi- cates blower output by flashing one (1) second for every 100 CFM of airflow.

H. COOLING MODE DEHUMIDIFICATION An Explanation of On Demand Dehumidification Use “On-Demand Dehumidification” (ODD) is an optional feature of the ECM interface board. The ODD allows the user to have automatic dehumidification in the cooling mode that is controlled by the user’s dehumidifying thermostat or humidistat setting. The humidistat should be wired between the ODD (grey) pigtail and the R (red) pigtail.
