Filters
Single phase units are shipped without a filter or filter racks. It is the responsibility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (1FF0110, 1FF0112 or 1FF0114).
A filter rack and high velocity filters are standard on three phase units.
Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly; this is especially important since this unit is used for both heating and cooling.
1. 8” Roof Curb also available.

Condensate Drain
A condensate trap is recommended to be installed in the condensate drain. The plumbing must conform to local codes.
Use a sealing compound on male pipe threads. Install the condensate drain line (3/4” NPTF) to spill into an open drain.
Hand tighten only.
Service Access
Access to all serviceable components is provided at the following locations:
• Blower compartment access panel
• Gas control/electrical access panel
• Refrigerant connections
Refer to Figure 3 for location of these access locations and minimum clearances in Table 5.
This system uses R-410A Refrigerant which operates at higher pressures than R-22. No other refrigerant may be used in this system. Gage sets, hoses, refrigerant containers and recovery systems must be designed to handle R-410A. If you are unsure, consult the equipment manufacturer. Failure to use R-410A compatible servicing equipment may result in property damage or injury.
Wear safety glasses and gloves when handling refrigerants. Failure to follow this warning can cause serious personal injury.
Refer to Figure 19 for the R-410A Quick Reference Guide.
Thermostat
The room thermostat should be located on an inside wal l approximately 56" above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow manufacturer's instructions enclosed with the thermostat for general installation procedure. Color coded insulated wires (minimum #18 AWG) should be used to connect thermostat to unit. See Figures 7 thru 10.
Power And Control Wiring
Field wiring to the unit must conform to provisions of the current N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be electrically grounded in accordance with local codes or, in their absence, with the N.E.C./C.E.C. Voltage tolerances which must be maintained at the compressor terminals during starting and running conditions are indicated on the unit Rating Plate and Table 6.
The wiring entering the cabinet must be provided with mechanical strain relief.
A fused disconnect switch should be field provided for the unit. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram.
Electrical line must be sized properly to carry the load. Each unit must be wired with a separate branch circuit fed directly from the meter panel and properly fused.
Refer to Figures 7 thru 10 for typical field wiring and to the appropriate unit wiring diagram for control circuit and power wiring information.

Compressors
The scroll compressor used in this product is specifically designed to operate with R-410A Refrigerant and cannot be interchanged.
Scroll compressors require proper rotation to operate properly. Failure to check and correct rotation may result in property damage.
This system uses R-410A Refrigerant which operates at higher pressures than R-22. No other refrigerant may be used in this system.
The compressor also uses a polyolester (POE oil), Mobil 3MA POE. This oil is extremely hydroscopic, meaning it absorbs water readily. POE oil can absorb 15 times as much water as other oils designed for HCFC and CFC refrigerants. Take all necessary precautions to avoid exposure of the oil to the atmosphere.
Do not leave the system open to the atmosphere. Unit damage could occur due to moisture being absorbed by the POE oil in the system. This type of oil is highly susceptible to moisture absorption
POE (polyolester) compressor lubricants are known to cause long term damage to some synthetic roofing materials.
Exposure, even if immediately cleaned up, may cause embrittlement (leading to cracking) to occur in one year or more. When performing any service that may risk exposure of compressor oil to the roof, take precautions to protect roofing.
Gas Heat
These single or two stage gas-fired heaters have aluminized­steel tubular heat exchangers with spark to pilot ignition.
Gas Piping
Proper sizing of gas piping depends on the cubic feet per hour of gas flow required, specific gravity of the gas and the length of run. National Fuel Gas Code Z223.1 or CSA B149.1 should be followed in all cases unless superseded by local codes or gas company requirements. Refer to Tables 9 and 10.
The heating value of the gas may differ with locality. The value should be checked with the local gas utility.
NOTE: There may be a local gas utility requirement specifying
a minimum diameter for gas piping. All units require a 1/2 inch pipe connection at the gas valve.
Gas Connection
The gas supply line can be routed through the hole located on the left side of the unit. Refer to Figure 3 to locate these access openings. Typical supply piping arrangements are shown in Figure 11.
Gas piping requirements:
1. A drip leg and a ground joint union must be installed in the gas piping.
2. When required by local codes, a manual shut-off valve may have to be installed outside of the unit.
3. Use wrought iron or steel pipe for all gas lines. Pipe dope should be applied sparingly to male threads only.
Procedures which risk oil leakage include, but are not limited to, compressor replacement, repairing refrigerant leaks, replacing refrigerant components such as filter drier, pressure switch, metering device or coil.
Units are shipped with compressor mountings which are factory-adjusted and ready for operation.
Do not loosen compressor mounting bolts.
Phasing
Three-phase, scroll compressors operate in only one dire ction. If the scroll is drawing low amperage, has similar suction and discharge pressures, or is producing a high noise level, the scroll is misphased. Change the incoming line connection phasing to obtain the proper rotation.

have been completed, open the main shut-off valve admitting normal gas pressure to the mains. Check all joints for leaks with soap solution or other material suitable for the purpose. NEVER USE A FLAME.
FIRE OR EXPLOSION HAZARD Failure to follow the safety warning exactly could result
in serious injury, death or property damage. Never test for gas leaks with an open flame. use a
commercially available soap solution made specifically for the detection of leaks to check all connections. A fire or explosion may result causing property damage, personal injury or loss of life.
6. The furnace must be isolated from the gas supply piping system by closing its individual manual shut-off valve before conducting any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.48 kPa).
Flue Vent Hood
The flue vent hood with screen is shipped loose. This hood must be installed to assure proper unit operation. The hood must be fastened to the outside of the side gas control/electrical compartment with the screws provided in the bag attached to the inside of the gas control/electrical compartment, see Figure 12.
If flexible stainless steel tubing is allowed by the authority having jurisdiction, wrought iron or steel pipe must be installed at the gas valve and extend a minimum of two (2) inches outside of the unit casing.
Natural gas may contain some propane. Propane being an excellent solvent, will quickly dissolve white lead or most standard commercial compounds. Therefore, a special pipe dope must be applied when wrought iron or steel pipe is used. Shellac base compounds such as gaskoloc or stalastic, and compounds such as rectorseal # 5, Clyde’s or John Crane may be used.
4. All piping should be cleaned of dirt and scale by hammering on the outside of the pipe and blowing out the loose dirt and scale. Before initial start-up, be sure that all of the gas lines external to the unit have been purged of air.
5. The gas supply should be a separate line and installed in accordance with all safety codes as prescribed under Limitations, shown on Page 3. After the gas connections
Flue hood surfaces may be hot.

1. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

Blower Speed Selection
The variable speed blowers are designed to deliver constant CFM regardless of the external static pressure (ESP) in the ductwork. Therefore, if too many supply registers are closed, a filter becomes clogged, or there is a restriction in the ductwork, the motor will automatically operate at a higher speed to compensate for the higher ESP. This may result in a higher operating sound level.
These units have variable speed motors that automatically adjust to provide constant CFM from 0.2" to 0.6" w.c. static pressure. From 0.6" to 1.0" static pressure, CFM is reduced by 2% per 0.1" increase in static. Operation on duct systems with greater than
1.0" w.c. external static pressure is not recommended.
To Set Cooling CFM for DNQ Units:
Refer to Airflow Performance Tables 15 and 16 for the possible cooling speed CFM selections.
Set “COOL” and “ADJ” Jumpers on the CFM selection board as indicated in Tables 15, 16 and Figure 13.
NOTE: CFM indicator light flashes once for every 100 CFM
(i.e. 12 flashes = 1200 CFM).
Fan Only CFM: When the connection is made from “R” to “G”, the fan only
mode is activated. In this mode, the blower will deliver 75% of the cooling system CFM. This connection is factory set from the manufacturer, but can be field adjusted.

The unit is controlled by a conventional heating/cooling thermostat common to this class of equipment.
Heating Sequence Of Operation
Heat
Do not change the “ADJ” tab position on the CFM selection board as this will change your cooling CFM previously selected.
To Set Delay Profile: Every unit has multiple cooling “blower off delay” profiles to
optimize system performance and efficiency. Refer to Table 19 for the regional climate in your area. Place the “DELAY” jumper tap on the CFM selection board on the appropriate pin setting.
Factory Set Gas Heat CFM: The blower speed required for gas heat is different than for
cooling. The heating CFM is factory set, but is adjustable. The “Heat” Jumper on the CFM selection board should be
set to “A” from the factory.

The control board begins a call for heat when W1 is energized (connected to R). The control ignores W2 until pilot ignition has been established.
The control checks to see if the pressure switch is open. If the pressure switch is closed, the control board flashes “3” on the LED and waits indefinitely for it to open. When the pressure switch is sensed as open, the control begins pressure switch proving period. If the call for heat is lost, the control goes back to Standby.
Pressure Switch Proving
The control board energizes the induced draft motor (High speed for 2 stage model) and waits for the low pressure switch to close. When the low pressure switch closes, the control begins Pre­purge period. If the call for heat is lost, the control de-energizes the inducer without post-purge and returns to standby.

437758-YIM-A-0409
If the low pressure switch does not close within 10 seconds of inducer energizing, the control board flashes “2” on the LED. If the pressure switch does not close within 5 minutes of inducer energizing, the control shuts off the inducer for 30 seconds, then energizes the inducer for another 5 minute try to close the pressure switch. This cycle continues indefinitely until either the pressure switch is proved closed, or the call for heat ends.
Pre-purge
The control board monitors the low pressure switch and ensures it remains closed during pre-purge. If the pressure switch opens, the control goes back to pressure switch proving mode. The control waits for a 15 second pre-purge period, then begins the ignition trial
Ignition Trial Period
The control board energizes the pilot gas valve and spark outputs for an 85 second Ignition trial. The control de-energizes the spark when flame is sensed and enters a flame stabilization period.
If flame is not established within the ignition trial period, the control de-energizes the spark and gas valve and begins an inter-purge period before attempting another ignition trial.
If the call for heat is lost during an ignition trial period, the control immediately de-energizes spark and gas. The control runs the inducer motor through a post purge period before de-energizing.
If the pressure switch is lost during an ignition trial period, the control immediately de-energizes spark and gas. The control begins pressure switch proving before an inter-purge and re­ignition attempt.
Pilot Flame Stabilization Period
The control board de-energizes the spark output, and waits for a 2 second flame stabilization period before energizing the main gas valve.
If flame is lost during the flame stabilization period, the control board counts it as a flame loss and retries ignition or locks out flashing a “5” on the LED.
Heat Blower On Delay
The control board waits for 30 seconds and then energizes the indoor blower heat speed. Blower on delay time begins at the start of flame proving period in the trial for ignition.
If the thermostat demand for heat is removed, the control de­energizes the gas valve, energizes the blower on heat speed and initiates a post-purge and heat blower off delay.
Main Burner Operation
High Heat Warm-up Two stage models run high heat for the first 60 seconds follo wing
Pilot Flame Stabilization period regardless of W2 demand. If W2 is not energized at the end of this 60 second period the control de energizes the high gas output and steps the inducer to low speed. If W2 is energized the control remains on high heat.
There is no high heat warm-up on single stage models. Low Heat
The control board keeps the pilot gas valve, main gas valve and induced draft motor energized while continuously monitoring the call for heat, low pressure switch, and flame status.
If the call for heat (W1) is lost, the control de-energizes the gas valve and begins post purge.
If low pressure switch open s, the control de-energizes the gas valve and begins pressure switch proving mode.
If flame is lost, the control de-energizes the gas valve within 2.0 second and counts the flame loss. If flame has been lost more than 16 times within the same call for heat, the control board locks out flashing “5” on the LED. If flame has been lost less than 16 times, the control attempts re-ignition after a 300 second inter-purge period.
High Heat If the W2 terminal was energized more than 1 second before
W1 at the start of the call for heat, and remains continuously energized through the call for heat, the control considers it to be connected to a single stage thermostat and implements a 10 minute Auto staging feature. The 2nd stage thermostat call is ignored until 10 minutes into steady heat (9 minutes after high heat warm-up ended).
The control recognizes a call for 2nd stage heat when W2 is energized (connected to “R”). The control energizes the high gas output and induced draft motor on high speed.
If the call for 2nd stage heat goes away and the 1st stage call remains, the control de energizes the high gas valve, drops inducer speed to low, and returns to low heat operation.
Response to loss of W1, low pressure switch, and flame are identical to low heat operation.
Post Purge
The control board runs the induced draft motor for a 30 second post-purge period, and then de-energizes the inducer. If a call for heat occurs during post-purge, the control finishes the post­purge, drops inducer out to re-prove open pressure switch before continuing with the heat cycle.
Heat Blower Off Delay
The control board de-energizes the indoor blower motor after a delay time as selected by movable shunt (60, 90, 120 or 180 seconds). Blower timing begins when the thermostat is satisfied or heat cycle was interrupted. The control returns to standby when the blower off delay is complete.
If the thermostat call for heat returns before the blower off delay is complete, the control begins an ignition sequence with pre­purge while the blower off delay continues.
Lockout
While in lockout, the control board keeps the pilot gas valve, main gas valve and induced draft motor de-energized.
26 Johnson Controls Unitary Products
Page 27
Lockouts due to failed ignition or flame losses may be reset by removing the call for heat (W1) for more than 1 second, but less than 20 seconds, or by removing power from the control for over 0.25 seconds. The control will automatically reset lockout after 60 minutes.
Lockouts due to detected internal control faults will reset after 60 minutes or power interruption.
High Temperature Limit Switch
Any time the high temperature limit switch is open the control board will run the indoor blower motor on heat speed, the inducer (on high speed for 2 stage models), de-energize the gas valve, and flash “6” on the LED. When the high temperature switch closes, the control will restart the ignition sequence beginning with pre-purge.
Rollout Switch
If the rollout switch opens for more than 0.25 seconds, the control board will run the inducer (on high speed for 2 stage models) for a post-purge period, immediately de-energize the gas valve, and flash “7” on the LED. The blower output will be energized during an open rollout condition.
If the rollout switch closes, the control shall remain locked out until power removed or “W” is removed.
Rollout switch lockout shall not reset automatically.
Power Interruptions
Power interruptions of any duration shall not cause lockout or any operation requiring manual intervention.
Flame present with Gas off
If flame is sensed for longer than 4.0 seconds during a period when the gas valve should be closed, the control will enter lockout flashing “8” on the LED. The control will turn on the inducer blower while the flame is present.
Gas Valve Stuck Open or Closed
If either or both Pilot and Main Gas valve outputs are sensed to be off for more than 1 second when commanded to be on, the control board shuts off all outputs and enters a hard lockout flashing "9" on the LED.
If the Pilot valve or Main valve output is sensed to be energized for more than 1 second when commanded to be off, the control de-energizes the induced draft motor (if flame is not present) to attempt to open the pressure switch to de-energize the gas valve. If the pilot or main gas valve is still sensed as energized after the inducer has been off for 5 seconds, the control re­energizes the inducer to attempt to vent the unburned gas. In either case, the control enters a hard lockout flashing "9" on the LED. If the pilot or main valve becomes Un-Welded the inducer will de-energize, but the control will remain in a hard lockout and not respond to any thermostat demands.
The only way to recover from a hard lockout is to remove and then reapply 24VAC power to the control board.
Flame Sense Circuit Failure
If the control detects an internal hardware failure in the flame sense circuit, it shuts off all outputs and enters a hard lockout flashing "10" on the LED. The control will not respond to thermostat demands during a hard lockout.
The only way to recover from a hard lockout is to remove and then reapply 24VAC power to the control. If problem persist after removal and reapplication of 24VAC power, the board may need to be replaced.
Safety Controls
The control circuit includes the following safety controls:
1. Limit Switch (LS) - This control is located inside the heat exchanger compartment and is set to open at the temperature indicated in the Temperature Controls Table of the unit wiring diagram. It resets automatically. The limit switch operates when a high temperature condition caused by inadequate supply air flow occurs, thus shutting down the ignition control and closing the main gas valve and energizing the blower.
2. Pressure Switch (PS) - If the draft motor should fail, the pressure switch prevents the ignition controls and gas valves from being energized.
3. Flame Sensor - The flame sensor and controls are located per Proper Flame Adjustment Figure 18. If an ignition control fails to detect a signal from the flame sensor indicating the pilot flame is properly ignited, then the main gas valve will not open.
4. Rollout Switch (RS) - This switch is located in the burner vestibule. In the event of a sustained main burner flame rollout, it shuts off the ignition control and closes the main gas valve.
NOTE: T he manual reset Rollout Switch (RS) must be reset
before allowing furnace operation.
5. Au
xiliary Limit Switch (ALS) - This control is located inside the heat exchanger compartment and is set to open at 160°F. It is a manual reset switch. If ALS trips, then the primary limit (LS) has not functioned correctly. Replace the primary limit LS.

Cooling Sequence Of Operations
When the thermostat calls for first-stage cooling, the thermostat terminals G and Y energize, signaling the compressor, indoor blower and outdoor fan to operate. The
Johnson Controls Unitary Products 27
Page 28
437758-YIM-A-0409
indoor blower will operate according to the fan delay profile selected using Table 19.
When the thermostat is satisfied, terminals G and Y are de­energized, thus stopping operation of the compressor and outdoor fan. The indoor blower will remain on according to the fan delay profile selected using Table 19.
Safety Controls
The control circuit includes the following safety controls:
1. High Pressure Switch (HP)- This switch protects against excessive discharge pressures due to a blocked condenser coil or a condenser motor failure (opens at 625 ± 25 psig and resets at 500 ± 25 psig).
2. Low Pressure Switch (LP)- This switch protects against loss of refrigerant charge (opens at 7 ± 3 psig and resets at 22 ± 5 psig).
The above pressure switches are specifically designed to operate with R-410A systems. R-22 pressure switches must not be used as replacements for the R-410A pressure switches.
The ability to properly perform maintenance on this equipment requires certain expertise, mechanical skills, tools and equipment. If you do not possess these, do not attempt to perform any maintenance other than those procedures recommended in this Installation Manual. Failure to heed this warning could result in serious injury and possible damage to this equipment.
Circulating Fan
When the thermostat calls for FAN, the thermostat terminal G is energized signaling the circulating fan to run at the heat speed 2 seconds after the G terminal is energized.
If a call for HEAT occurs, the circulating fan continues to run at the heat speed.
If a call for COOL occurs, the circulating fan switches to cool speed according to the fan delay profile selected in Table 19.
When the thermostat ends the call for FAN, the thermostat terminal G is de-energized, de-energizing the circulating fan.

Adjustment of Temperature Rise
After about 20 minutes of high heat operation, determine the furnace temperature rise. Take readings of both the return air and the heated air in the ducts about six feet from the furnace where they will not be affected by radiant heat.
The temperature rise (or temperature difference between the return air and the heated air from the furnace) must lie within the range shown on the rating plate and the data in Tables 11 thru 14.
After the temperature rise has been determined, the CFM can be calculated as follows:
Degrees F Temp Rise =
BTUH Output
1.08 x CFM
OR
CFM=
1.08 x Degrees F Temp Rise
Direct Drive Blower
All units have direct drive, constant CFM blower motors.
BTUH Output
Checking Gas Heat Input
Natural Gas
1. Turn off all other gas appliances connected to the gas meter.
2. With the furnace turned on, measure the time needed for one revolution of the hand on the smallest dial on the
meter. A typical gas meter usually has a 1/2 or a 1 cubic foot test dial.
3. Using the number of seconds for each revolution and the size of the test dial increment, find the cubic feet of gas consumed per hour from Table 21.
If the actual input is not within 5% of the furnace rating with allowance being made for the permissible range of the regulator setting, replace the orifice spuds with spuds of the proper size.
NOTE: To find the BTU input, multiply the number of cubic feet
of gas consumed per hour by the BTU content of the gas in your particular locality. (Contact your gas company for this information since it varies widely from city to city.)

1. EXAMPLE: By actual measurement, it takes 38 seconds for the hand on the 1-cubic foot dial to make a revolution with just a 100,000 BTUH furnace running. Using this information, locate 38 seconds in the first column of Table 21. Read across to the column headed “1 Cubic Foot,” where you will see that 95 cubic feet of gas per hour are consumed by the fur nace at th at rate. Multiply 95 x 1050 (the BTU rating of the gas obta ined fro m the local gas company). The result is 99,750 BTUH, which is close to the 100,000 BTUH rating of the furn ace.

R-410A QUICK REFERENCE GUIDE
Refer to Installation Instructions for specific installation requirements.
R-410A Refrigerant operates at 50 - 70 percent higher pressures than R-22. Be sure that servicing equipment and replacement components are designed to operate with R-410A. R-410A Refrigerant cylinders are rose colored. Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400, or DOT BW400. Recovery equipment must be rated for R-410A. Do Not use R-410A service equipment on R-22 systems. All hoses, gages, recovery cylinders, charging cylinders and recovery equipment must be dedicated for use on R-410A systems only. Manifold sets must be at least 700 psig high side, and 180 psig low side, with 550 psig retard. All hoses must have a service pressure rating of 800 psig. Leak detectors must be designed to detect HFC refrigerants. Systems must be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose. R-410A can only be used with POE type oils. POE type oils rapidly absorb moisture from the atmosphere. Vacuum pumps will not remove moisture from POE type oils. Do not use liquid line driers with a rated working pressure rating less than 600 psig. Do not install suction line driers in the liquid line. A liquid line drier is required on every unit. Do not use a R-22 TXV. If a TXV is to be used, it must be a R-410A TXV. Never open system to atmosphere when under a vacuum. If system must be opened for service, evacuate system then break the vacuum with dry nitrogen and replace all filter driers.
