164015-YIM-A-0905 Duct Covers Units are shipped with the side duct openings covered and a covering over the bottom of the unit. For bottom duct application, no duct cover changes are necessary. For side duct application, remove the side duct covers and install over the bottom duct openings. The panels removed from the side duct connections are designed to be reused by securing each panel to its respective downflow opening.

164015-YIM-A-0905 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.

164015-YIM-A-0905 3. Use an Inclined Manometer or Magnehelic to determine the pressure drop across the unit. This is the External Static Pressure (ESP). In order to obtain an accurate measurement, be certain that the air filters are clean. 4. Determine the number of turns the variable motor sheave is open. 5. Select the correct blower performance table for the unit from Tables 16 and 17. Tables are presented for side and downflow configuration. 6.

164015-YIM-A-0905 Supply Air Drive Adjustment EXAMPLE A 12.5 ton unit was selected to deliver 4,000 CFM with a 3 HP motor, but the unit is delivering 3,800 CFM. The variable pitch motor sheave is set at 2 turns open. Before making any blower speed changes review the installation for any installation errors, leaks or undesirable systems effects that can result in loss of airflow. Even small changes in blower speed can result in substantial changes in static pressure and BHP.

164015-YIM-A-0905 Operation Cooling Sequence Of Operation For the Predator® series of units, the thermostat makes a circuit between "R" and "Y1" for the first stage of cooling. The call is passed to the Unit Control Board (UCB), which then determines whether the requested operation is available and, if so, which components to energize. For gas heating, the UCB monitors the "W1" call but does not handle the operation of the gas furnace. An ignition control board controls the gas heater operation.
PAGE 53
164015-YIM-A-0905 addition. The power exhaust motor is energized 45 seconds after the actuator position exceeds the exhaust fan set point on the economizer control. When the power exhaust is operating, the second stage of mechanical cooling will not operate. As always, the "R" to "G" connection provides minimum position but does not provide power exhaust operation. Motorized Outdoor Air Dampers This system operation is the same as the units with no outdoor air options with one exception.
PAGE 54
164015-YIM-A-0905 Compressor Protection Limit Switch (Ls) In addition to the external pressure switches, the compressors also have inherent (internal) protection. If there is an abnormal temperature rise in a compressor, the protector will open to shut down the compressor. The UCB incorporates features to minimize compressor wear and damage. An Anti-Short Cycle Delay (ASCD) is utilized to prevent operation of a compressor too soon after its previous run.
PAGE 55
164015-YIM-A-0905 value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperature within the conditioned space. Refer to Table 23 for the required electric heat anticipator setting. Table 24: Electric Heat Anticipator Setpoints SETTING, AMPS W1 W2 0.13 0.1 Gas Heating Sequence Of Operations When the thermostat calls for the first stage of heating, the lowvoltage control circuit from “R” to “W1” is completed.
PAGE 56
164015-YIM-A-0905 Gas Valve Table 25: Gas Heat Limit Control Settings1 The UCB and ICB continuously monitor the GV. If the ICB senses voltage at the GV when not requested, the ICB will energize the draft motor. The ICB will not operate the furnace until voltage is no longer sensed at the GV. The draft motor is stopped when voltage is not sensed at the GV.
PAGE 57
164015-YIM-A-0905 Gas Heat Anticipator Setpoints Start-Up (Gas Heat) It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON cycles and may result in the lowering of the temperature within the conditioned space. Refer to Table 26 for the required gas heat anticipator setting.
PAGE 58
164015-YIM-A-0905 Shut Down 1. Set the thermostat to the lowest temperature setting. 2. Turn “OFF” all electric power to unit. 3. Open gas heat access panel. 4. Turn gas valve clockwise to “OFF” position (See Figure 33). Checking Gas Heat Input This unit has two stages of gas heat. The first stage is 60% of the full fire input and is considered the minimum input for the furnace. The intended input for each furnace is shown in Table 27. The table applies to units operating on 60 Hz power only.
PAGE 59
164015-YIM-A-0905 Adjust second stage (100% input) pressure first, then adjust first stage (60% input) pressure. 1. Turn off all power to the unit. 2. Using the outlet pressure port on the gas valve, connect a manometer to monitor the manifold pressure. 3. Remove plastic cap covering HI and LO pressure adjustment screws. 4. 5. 6. Before checking or changing burners, pilot or orifices, CLOSE MAIN MANUAL SHUT-OFF VALVE AND SHUT OFF ALL POWER TO THE UNIT. 1.

164015-YIM-A-0905 Cooling Troubleshooting Guide the economizer provides free cooling, following a short delay compressor #1 will be energized unless it is locked out. If compressor #1 is locked out, compressor #2 is energized. Compressor #2 is always energized in place of compressor #1 when compressor #1 is requested but locked out.
PAGE 64
164015-YIM-A-0905 out, the UCB may have the compressor in an ASCD. Check the LED for an indication of an ASCD cycle. The ASCD should time out within 5 minutes. Press and release the TEST button to reset all ASCDs. 11. If 24 volts is present at the UCB Y1 terminal and the compressor is not out due to a protective switch trip, repeat trip lock out, or ASCD, the economizer terminals of the UCB may be improperly wired. Check for 24 volts at the Y1 “OUT” terminal of the UCB.
PAGE 65
164015-YIM-A-0905 11. The UCB can be programmed to lock out compressor operation during free cooling and in low ambient conditions. These options are not enabled by default. Local York distributors can test the UCB for this programming. 12. If none of the above corrected the error, test the integrity of the UCB. Disconnect the C2 terminal wire and jumper it to the Y2 terminal. DO NOT jump the Y2 to C2 terminals. If the compressor engages, the UCB has faulted. 13.
