of the Long-Line Guideline section in the Application Guideline and Service Manual for Residential Split-System Air Conditioners and Heat Pumps Using Puron® Refrigerant. If required by Long-Line Application Guideline, install LSV kit Part No. KHALS0401LLS specifically designed for Puron® Heat Pumps. LSV should be installed between filter drier and indoor coil as close as possible to filter drier. Follow the Installation Instructions included with accessory kit.

IMPORTANT: Flow arrow must point toward outdoor unit.

VII. MAKE PIPING CONNECTIONS

WARNING: Relieve pressure and recover all refrigerant before system repair or final unit disposal to avoid personal injury or death. Use all service ports and open all flow-control devices, including solenoid valves.

CAUTION: Do not leave system open to atmosphere any longer than minimum required for installation. POE oil in compressor is extremely susceptible to moisture absorption. Always keep ends of tubing sealed during installation.

CAUTION: To prevent compressor damage DO NOT bury more than 36 in. of refrigerant tubing. If ANY tubing is buried, provide 6-in. vertical rise at service valve.

Outdoor units may be connected to indoor section using accessory tubing package or field-supplied refrigerant grade tubing of correct size and condition. Tubing diameters listed in Table 1 are adequate for equivalent lengths up to 50 ft For tubing requirements beyond 50 ft, substantial capacity and performance losses can occur. Follow the recommendations in the Application Guideline and Service Manual for Residential Split-System Air Conditioners and Heat Pumps Using Puron® Refrigerant to minimize losses. Refer to Table 1 for field tubing diameters. Refer to Table 2 for accessory requirements.

If refrigerant tubes or indoor coil are exposed to atmosphere, they must be evacuated to 500 microns to eliminate contamination and

Notes:

1.Tube diameters are for lengths up to 50 equivalent ft and/or 20 ft vertical differential.

2.Do not increase or decrease tubing sizes.

3.If required by local codes, Pressure Guard™ kit is available. See Product Data Sheet for part numbers.

A. OUTDOOR UNIT CONNECTED TO FACTORY- APPROVED INDOOR UNIT

These outdoor units are carefully evaluated and listed with specific indoor coils for proper system performance.

IMPORTANT: Do not apply indoor coils which are not factory approved to these units.

IMPORTANT: For 036 size units matched with the FV/FK005 or FV/FK006 and the 698BNX048 matched with the FV/FK006, a piston change is required. Refer to the KHAPX0201BPA Instal- lation Instructions for details.

B.INSTALL ADAPTER TUBE

1.Remove plastic retainer holding outdoor piston in liquid service valve.

2.Check to be sure outdoor piston is properly installed in liquid service valve.

3.Locate plastic bag taped to unit containing adapter tube.

4.Remove Teflon washer from bag and install on open end of liquid service valve. (See Fig. 8.)

5.Remove adapter tube from bag and connect threaded nut to liquid service valve. Tighten nut finger tight and then with wrench an additional 1/2 turn (15 ft-lb). DO NOT OVER TIGHTEN!
