SAFETY CONSIDERATIONS Installation of this accessory can be hazardous due to system
pressures, electrical components, and equipment location (such as a roof or elevated structure).
Only trained, qualified installers and service technicians should install, start up, and service this equipment.
When installing this accessory, observe precautions in the liter- ature and on any labels attached to the equipment, and all other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. Use care in handling and installing this accessory.
GENERAL The remote evaporator mounting accessory permits indoor
relocation of the evaporator from 30RAP units up to 50 ft (15.2 m) of piping away from the base unit with a maximum evaporator elevation above the condensing section of 15 ft (4.5 m). Relocating the evaporator introduces minimal line losses if correct piping practices are followed. See Tables 2 and 3 for accessory package usage and contents.
In addition to the parts supplied with the accessory package, the following material must be field-supplied: refrigerant grade liquid, hot gas bypass, and suction line
piping (length determined by installation) water piping and fittings suction and water line tubing insulation (length determined
by installation) electrical conduit (length determined by installation) assorted refrigerant grade fittings according to site require-
ments (elbows, tees, refrigerant pipe couplings, etc.) 90 C appliance wire 16 AWG if evaporator heater installa-
tion is required. (Length determined by installation). 1/2 in. strain reliefs
INSTALLATION Perform the following to install the remote evaporator mount-
ing accessory: 1. Inspect package contents for any missing or damaged
parts. File a claim with the shipping agency if parts are damaged. Notify your Carrier representative if any item is missing.
2. Turn off the electrical power to the unit using the optional disconnect or the field-installed disconnect and lock off us- ing proper lockout and tag-out procedures.
3. Recover holding charge or refrigerant charge from all cir- cuits using standard refrigeration practices before cutting any refrigerant lines.
4. Disconnect water lines, thermistors, flow switch, EXV (elec- tronic expansion valve) cable(s) and evaporator heater wir- ing.
5. Because the 30RAP units use polyolester (POE) oil, which can absorb moisture, it is important to minimize the amount of time that the system interior is left exposed to the atmo- sphere. Minimizing the exposure time of the oil to the atmo- sphere will minimize the amount of moisture that needs to be removed during evacuation.
6. Cut suction, liquid and hot gas bypass (if equipped) lines in area shown in Fig. 1-5. Remove evaporator/EXV assembly from unit.
WARNING
Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work is completed.
WARNING
DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective gloves and goggles and proceed as follows: a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure from system
using both high-pressure and low pressure ports. c. Traces of vapor should be displaced with nitrogen and
the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system.
e. Carefully un-sweat remaining tubing stubs when neces- sary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal injury or death.
CAUTION
This system uses R-410A, which has higher pressures than R-22 and other refrigerants. No other refrigerant may be used in this system. Suction tubing design pressure is 445 psig (3068 kPa) and liquid tubing design pressure is 656 psig (4522 kPa). Failure to use gage set, hoses, and recovery systems designed to handle R-410A refrigerant may result in personal injury and equipment damage. If unsure about equipment, consult the equipment manufac- turer.

7. Install evaporator heater if necessary; if evaporator will be located in area with ambient temperature above 40F or applied with fluid suitably treated for freeze protection, then evaporator heater is not required. Refer to the power schematic located inside the control box for heater con- nection detail and follow the local electrical code. Care- fully note refrigerant and water connections. Install evap- orator in suitable location that can support the weight of the evaporator while operating. Install evaporator verti- cally as shown in Fig. 3 and 5. For 070-150, reposition filter drier as necessary.
8. Install field-supplied suction lines, hot gas bypass lines (if re- quired), and liquid refrigerant lines from unit to evaporator according to Fig. 6-9 and Tables 4-6, using standard refriger- ation practices. Use a nitrogen purge while brazing refriger- ant lines. Be careful to route piping to proper refrigerant cir- cuit. It is required that liquid line filter driers be installed be- tween the condenser(s) and the expansion device(s) to
capture any foreign debris and provide additional moisture removal capacity.
9. Double suction riser is required on some units if refrigerant flow is up. See Table 6 for required units and piping details. Refer to Fig. 10 for suction riser and speed riser piping diagram.
10. If hot gas bypass valve is used in remote applications, the line size should be kept to a minimum to reduce the amount of liquid refrigerant that can condense in the line during the off cycle. Liquid refrigerant in the hot gas bypass line can re- sult in a liquid slug entering the compressor at start-up. Line size is not as critical as if sizing for discharge lines, therefore 5/8 in. OD line size is recommended for all applications. For 30RAP010-060, dual circuit units should use circuit A hot gas bypass only. For 30RAP070-150, use both circuits hot gas bypass. It is important to loop the hot gas bypass line over the compressor to help reduce the chance of the hot gas bypass line filling with liquid in the off cycle. The hot gas bypass valve remain with the outdoor portion of the unit. If hot gas bypass valve is installed as a factory-installed option, cut the line outlet of the valve and run the hot gas bypass line to the remote evaporator. Leave the hot gas bypass control solenoid valve where it is already located.

Table 6 Double Suction Riser Line Sizing
Fig. 10 Suction Riser/Speed Riser Piping 11. Once all of the piping connections are complete, leak test the
unit and then pull a deep dehydration vacuum. Connect the vacuum pump to the charging valve in the suction line and to the liquid line service valve. For best results, it is recom- mended that a vacuum of at least 500 microns be obtained. Afterwards, to ensure that no moisture is present in the sys- tem, perform a standing vacuum-rise test. With the unit in deep vacuum (500 microns or less), isolate the vacuum pump from the system. Observe the rate-of-rise of the vacu- um in the system. If the vacuum rises by more than 50 mi- crons in a 30-minute time period, then continue the dehydra- tion process. Maintain a vacuum on the system until the standing vacuum requirement is met. This will ensure a dry system. By following these evacuation and dehydration pro- cedures, the amount of moisture present in the system will be minimized.
12. Install evaporator heater (if necessary). If evaporator will be located in an area with ambient temperatures above 40F (4.4C) or applied with fluid suitably treated for freeze protection, then the evaporator heater is not required.
13. Insulate evaporator with original insulation or suitable alternative if needed. Removal of insulation is not rec- ommended.
14. Remove water strainer from unit and reinstall in new water inlet piping within 10 ft (3 m) of the evaporator. Install re- mainder of water piping.
15. Install entering and leaving water thermistor wells (included in kit). Thermistors should be located within 1 ft (0.3 m) of the evaporator inlet and outlet.
16. Install a 1/4 NPT fitting for the flow switch. Flow switch should be installed with at least 2 pipe diameters of straight tube in front of and behind switch and no water-side service valves between the flow switch and the evaporator. Flow switch should be installed near evaporator. Piping containing
switch should be no smaller in diameter than field-supplied water lines. Remove water flow switch from the unit and re- install in new piping. Route flow switch extension cable from the flow switch to the unit and plug it into the flow switch cable assembly, which was previously disconnected. Coil excess cable and wire tie in a convenient location.
17. Label and cut EWT (entering water temperature) and LWT (leaving water temperature) thermistors approximately 1 ft from the MBB (main base board) connector. For 30RAP010-060 units with a Packard Weather-Pack1 EXV connector cable, label and cut EXV cable(s) approximately 1 ft from the EXV board connector. For 30RAP010-060 with an M12 EXV connector cable and all 30RAP070-090 units, label and disconnect the existing cable.
18. The junction box supplied with the accessory is for splicing the thermistor leads and EXV Packard Weather-Pack EXV connector leads (30RAP010-060) from the evaporator with the cables from the base unit. Mount the junction box near the liquid refrigerant connection end of evaporator. One or two knockouts can be used. Remove a knockout from the bottom of the junction box and install HW60EA001 conduit connector for strain relief at the knockout hole. If using con- duit to provide mechanical protection to the wires between the junction box and the base unit, remove another knockout. Follow local codes.
19. Install thermistors into thermistor wells in entering and leav- ing water piping. Run the labeled thermistor leads from the evaporator into the junction box and tighten the strain relief. Strip back the lead jackets to expose the 2 wires in each lead.
20. A 150 ft (45.7 m), 2-conductor jacketed cable is provided to connect the thermistor leads in the junction box back to the base unit. Cut the cable in half. Label both ends of one cable EWT. Label both ends of the other cable LWT. Run one end of the jacketed cables into the junction box and splice the cable wires to the identically tagged thermistor leads. Solder the splices and insulate them to prevent shorting.
21. For 30RAP010-060 units with the Packard Weather-Pack EXV connector: a. A 150 ft (45.7 m), 4-wire jacketed cable is provided to
connect the EXV leads in the junction box back to the base unit. Each wire in the jacketed cable is a different color. Cut the cable in half. Label each end of one of the EXV cable EXV A.
b. Label the ends of the other cable EXV B (if present).

For 30RAP010-060 with M12 EXV connectors and 30RAP070-150 units: a. Label each end of one of the EXV extension cable
assemblies supplied with the accessory EXV A. Label the ends of the other assemblies EXV B.
b. Plug the electrical connectors of the appropriate EXV cable assemblies into the EXVs.
c. Run the other end of the cable assemblies to the base unit.
d. Plug the accessory EXV cable assemblies into the corresponding EXV leads located at the base unit where the EXV assemblies were removed.
e. Coil excess cables and wire tie in a convenient location.
22. For 30RAP010-060 units only, install crankcase heaters, one per compressor, and terminate in control box according to unit schematic diagram. See Table 7-9 for heater part num- bers. See Fig. 11-16 for heater locations.
23. Charge machine with refrigerant using nameplate charge amount. Add charge according length of interconnecting piping. Charge at the liquid line. Do not charge into suction line or compressor damage will occur. Charge per unit instal- lation instructions. Note the final charge amount for each cir- cuit when complete on the unit.
Preliminary charge is based on 25 ft (7.6 m) of interconnect- ing liquid line piping between indoor and outdoor units. For liquid line piping longer than 25 ft (7.6 m), use the following information:
24. Check suction gas superheat for both circuits during steady operation. Increase set point if required, to account for suc- tion line pressure drop and heat gain so that there is an 8F (4.4C) superheat leaving the evaporator when measured at the evaporator. Inspect the compressor oil sump during steady operation to ensure that oil is not foaming due to liq- uid flooding.
25. Check operation according to unit Controls, Start-Up, Oper- ation, Service and Troubleshooting manual and adjust oil and refrigerant charge as necessary. After adjusting the re- frigerant charge, allow each circuit to run fully loaded for 20 minutes. Stop the compressors and check the oil level. Oil level should be 1/8 to 3/8 up on the sight glass. Add oil only if necessary to bring the oil into view in the sight glass. If oil is added, run the circuit for an additional 10 minutes, then stop and check oil level. If the level remains low, check the piping system for proper design for oil return; also, check the sys- tem for leaks. If checking the oil level with unit running in part load, let unit run one hour, then run at full load for 10 minutes. If oil does not return to acceptable sight glass lev- els, check for correct suction piping and line sizing. Oil must be added if the oil level does not meet the requirements.
26. Replace filter drier or filter drier core if pressure drop be- comes excessive after 24 hours of operation.
