of the Long-Line Guideline section in the Application Guideline
and Service Manual_ir Conditioners and Heat Pumps Using
Puron,_.R)Refrigerant. If required by Long-Line Application Guide-
line, install LSV kit P.N KHALS0401LLS specifically designed
for Puron(R_ Heat Pump. LSV should be installed between filter
drier and indoor coil as close as possible to outdoor unit (within 2
feet). (See Fig. 13 for wiring diagram.) Follow the Installation
Instructions included with accessory kit.
IMPORTANT: Flow arrow nmst point toward outdoor unit.
Step 7--Make Piping Connections
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.

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.
¥:I [,.1._luijl[ol'd
If ANY refrigerant tubing is buried, provide a 6 in. vertical
rise at service valve. Rel_dgerant tubing lengths up to 36 in.
may be buried without further special consideration. Do NOT
bury lines for lengths over 36 in.
Outdoor units may be connected to indoor section using accessory
tubing package or field-supplied refi'igerant grade tubing of correct
size and condition. Tubing diameters listed in Table 1 are adequate
for equivalent lengths up to 50 It. For tubing requirements beyond
50 ft, substantial capacity and performance losses will occur.
Follow the recommendations in the Application Guideline and
Service Manual Air Conditioners and Heat Pumps Using Pu-
ron_ Refrigerant to minimize losses.
Refer to Table 1 for field tubing diameters. Refer to Table 2 for
accessory requirements.

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 TM kit is available See Product
Data Digest for part numbers.
If refrigerant tubes or indoor coil are exposed to atmosphere, they
must be evacuated to 500 microns to eliminate contamination and
moisture in the system.
OUTDOOR !EXIT CONNECTED TO FACTORY-APPROVED
INDOOR UNIT
These outdoor units are carefully evaluated and listed with specific
indoor coils for proper system perfomlanee.
IMPORTANT: Do not apply to indoor coils that are not factory
approved combinations.
IMPORTANT: For 036 size units matched with the
FV.40FKiFK005 or the FVi40FKiFK006, or lbr the 38YDB048
used with the FVi40FKiFK006, a piston change is required. Refer
to the KHAPX0201CPA Installation Instructions for details.
INSTALL ADAPTER TUBE
i. Remove plastic retainer holding outdoor piston in liquid line
service valve.
2. Check to be sure outdoor piston is properly installed in liquid
line service valve.
3. Locate plastic bag taped to unit containing adapter tube.
4. Remove Teflon washer fi'om bag and install on open end of
liquid service valve.
5. Remove adapter tube from bag and connect threaded nut to
liqnid service valve. Tighten nut finger tight and then with
wrench an additional i/2 tum (15 ft-lb). DO NOT OVER-
TIGHTEN!
REFRIGERANT TUBING AND FILTER DRIER
Connect vapor tubing to fittings on outdoor unit vapor service
valve. Connect liqnid tubing to filter &ier. (See Table 1 and Fig.
9.) Connect other end of filter drier to adapter tube on liquid line
smwice valve.
