Start —Up PERSONAL INJURY HAZARD Failure to follow this caution may result in personal injury. Wear safety glasses, protective clothing, and gloves when handling refrigerant and observe the following: • Front seating service valves are equipped with Schrader valves. ENVIRONMENTAL HAZARD Failure to follow this caution may result in environmental damage. Federal regulations require that you do not vent refrigerant to the atmosphere. Recover during system repair or final unit disposal. UNIT OPERATION AND SAFETY HAZARD Failure to follow this caution may result in personal injury, equipment damage or improper operation. • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. • Do not disable low pressure switch in scroll compressor applications. • Compressor dome temperatures may be hot. Follow these steps to properly start up system: 1. After system is evacuated, fully open liquid and vapor service valves. 2. Unit is shipped with valve stem(s) front seated (closed) and caps installed. Replace stem caps after system is opened to refrigerant flow (back seated). Replace caps finger —tight and tighten with wrench an additional 1/12 turn. 3. Close electrical disconnects to energize system. 4. Set room thermostat at desired temperature. Be sure set point is below indoor ambient temperature for cooling mode operation. 5. Set room thermostat to HEAT or COOL and fan control to ON or AUTO mode, as desired. Operate unit for 15 minutes. Check system refrigerant charge. Sequence of Operation Turn on power to indoor and outdoor units. Transformer is energized. Cooling On a call for cooling, thermostat makes circuits R-0 and R—Y, and R—G. Circuit R—O energizes reversing valve, switching it to cooling position. Circuit R—Y energizes contactor, starting outdoor fan motor and compressor circuit. R—G energizes indoor unit blower relay, starting indoor blower motor on high speed. When thermostat is satisfied, its contacts open, de —energizing contactor and blower relay. Compressor and motors should stop. If indoor unit is equipped with a time —delay relay circuit, the indoor blower will run an additional 90 seconds to increase system efficiency. Heating On a call for heating, thermostat makes circuits R—Y and R—G. Circuit R—Y energizes contactor, starting outdoor fan motor and compressor. Circuit R—G energizes indoor blower relay, starting blower motor on high speed. Should temperature continue to fall, R—W2 is made through second — stage room thermostat. Circuit R—W2 energizes a relay, bringing on first bank of supplemental electric heat and providing electrical potential to second heater relay (if used). If outdoor temperature falls below setting of outdoor thermostat (field installed option), contacts close to complete circuit and bring on second bank of supplemental electric heat. When thermostat is satisfied, its contacts open, de —energizing contactor and relay. All heaters and motors should stop. Quiet Shift-2 Quiet Shift-2 is a field selectable defrost mode (factory set to OFF), which will reduce the occasional noise that could be heard at the start of defrost cycle and restarting of heating cycle. It is selected by placing DIP switch 3 on defrost board in the ON position. Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations. 225S: Installation Instructions When Quiet Shift-2 switch is placed in ON position, and defrost is initiated, the following sequence of operation will occur: — The compressor will be de --energized for approximately 1 minute, then the reversing valve will be energized. A few seconds later, the compressor will be re -energized and the normal defrost cycle starts. Once defrost termination conditions have been met, the following sequence will occur: — The compressor will be de -energized for approximately 1 minute, then the reversing valve will be de -energized. A few seconds later, the compressor will be re -energized and the normal heating cycle starts. Defrost The defrost control is a time/temperature control which includes a field selectable time period between defrost cycles (30, 60, 90, or 120). The time period is selected using DIP switches located on the board. The setting is initial period only then varies with defrost length. The defrost thermostat senses coil temperature throughout the heating cycle. When the coil temperature reaches the defrost thermostat setting of approximately 32°F (0°C), it will close, which energizes the DFT terminal and begins the defrost timing sequence. The timer runs only when the defrost thermostat is closed and the contactor is energized. Defrost mode is identical to cooling mode except that outdoor fan motor stops and second -stage heat is turned on to continue warming conditioned spaces. Defrost Speedup Quiet Shift-2 Models To initiate a forced defrost, speedup pins (II) must be shorted with a flat head screwdriver for 5 seconds and RELEASED. If the defrost thermostat is open, a short defrost cycle will be observed (actual length depends on Quiet Shift-2 switch position). When Quiet Shift-2 is off, only a short 30 second defrost cycle is observed. With Quiet Shift-2 ON, the speedup sequence is approximately 3 minutes; 1 minute compressor off period followed by 30 seconds of defrost with compressor operation. When returning to heating mode, the compressor will turn off for an additional minute. If the defrost thermostat is closed, a complete defrost cycle is initiated. If the Quiet Shift-2 switch is turned on, the compressor will be turned off for two 1-minute intervals as explained previously.

Additional subcooling may be required to achieve optimal heating performance based on the installed indoor unit. (see Table 5). Charging method is shown on information plate inside unit. For TXV, use subcooling method. For piston, use superheat method. To properly check or adjust charge, conditions must be favorable for subcooling or superheat charging. Favorable conditions exist when the outdoor temperature is between 70°F and 100°F (21.11°C and 37.78°C), and the indoor temperature is between 70°F and 80°F (21.11°C and 26.67°C). Follow the procedure below: Unit is factory charged for 15ft (4.57 m) of lineset. Adjust charge by adding or removing 0.6 oz/ft (.018 kg/m) of 3/8 liquid line above or below 15ft (4.57 m) respectively. For standard refrigerant line lengths (80 ft/24.38 m or less), allow system to operate in cooling mode at least 15 minutes. If conditions are favorable, check system charge by super heat method for fixed metering device and subcooling method for TXV. If any adjustment is necessary, adjust charge slowly and allow system to operate for 15 minutes to stabilize before declaring a properly charged system. Refer to Table 5 for additional subcooling required. If the indoor temperature is above 80°F (26.67°C), and the outdoor temperature is in the favorable range, adjust system charge by weight based on line length and allow the indoor temperature to drop to 80OF (26.67°C) before attempting to check system charge by subcooling method as described above. If the indoor temperature is below 70°F (21.11 °C), or the outdoor temperature is not in the favorable range, adjust charge for line set length above or below 15ft (4.57 m) only. Charge level should then be appropriate for the system to achieve rated capacity. The charge level could then be checked at another time when the both indoor and outdoor temperatures are in a more favorable range. If line length is beyond 80 ft (24.38 m) or greater than 20 ft (6.10 m) vertical separation, See Residential Piping and Long Line Guideline for special charging requirements. Units with Cooling Mode TXV Units installed with cooling mode TXV require charging by the subcooling method. 1. Operate unit a minimum of 15 minutes before checking charge. 2. Measure liquid service valve pressure by attaching an accurate gage to service port. 3. Measure liquid line temperature by attaching an accurate thermistor type or electronic thermometer to liquid line near outdoor coil. 4. Refer to unit rating plate for required subcooling temperature. 5. Refer to Table 6. Find the point where required subcooling temperature intersects measured liquid service valve pressure. 6. To obtain required subcooling temperature at a specific liquid line pressure, add refrigerant if liquid line temperature is higher than indicated or reclaim refrigerant if temperature is lower. Allow a tolerance of ?3°F. Units with Indoor Pistons Units installed with indoor pistons require charging by the superheat method. The following procedure is valid when indoor airflow is within 20 percent of its rated CFM. 1. Operate unit a minimum of 15 minutes before checking charge. 2. Measure suction pressure by attaching an accurate gage to suction valve service port. 3. Measure suction temperature by attaching an accurate thermistor type or electronic thermometer to suction line at service valve. 4. Measure outdoor air dry-bulb temperature with thermometer. 5. Measure indoor air (entering indoor coil) wet -bulb temperature with a sling psychrometer. 6. Refer to Table 7. Find outdoor temperature and evaporator entering air wet -bulb temperature. At this intersection, note superheat. Where a dash (-) appears on the table, do not attempt to charge system under these conditions or refrigerant slugging may occur. Charge must be weighted in, adding or removing 0.6 oz/ft of 3/8 liquid line above or below 15 ft (4.57 m) respectively. 7. Refer to Table 8. Find superheat temperature located in item 6 and suction pressure. At this intersection, note suction line temperature. 8. If unit has a higher suction line temperature than charted temperature, add refrigerant until charted temperature is reached. 9. If unit has a lower suction line temperature than charted temperature, reclaim refrigerant until charted temperature is reached. 10. When adding refrigerant, charge in liquid form into suction service port using a flow -restricting device. I L If outdoor air temperature or pressure at suction valve changes, charge to new suction line temperature indicated on chart. 12.Optimum performance will be achieved when the operating charge produces 51 to 6°F suction superheat at suction service valve with 82°F outdoor ambient and 80°F (26.7°C) dry bulb 67°F (19.4°C) wet bulb indoor temperature (DOE °B" test conditions) at rated airflow. Heating Check Chart Procedure To check system operation during heating cycle, refer to the Heating Check Chart on outdoor unit. This chart indicates whether a correct relationship exists between system operating pressure and air temperature entering indoor and outdoor units. If pressure and temperature do not match on chart, system refrigerant charge may not be correct. Do not use chart to adjust refrigerant charge.
