NOTE: Read the entire instruction manual before starting the installation. SAFETY CONSIDERATIONS Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause death, personal injury, or property damage.
INSTALLATION I. CHECK EQUIPMENT AND JOB SITE A. UNPACK UNIT Move to final location. Remove carton, taking care not to damage unit. B. INSPECT EQUIPMENT File claim with shipping company prior to installation if shipment is damaged or incomplete. Locate unit rating plate on unit corner panel.
VI. CHECK INDOOR EXPANSION DEVICE CAUTION: For proper unit operation and reliability, units must be installed with balance port hard shutoff TXV specifically designed to operate with Puron ® two- speed unit. Do not install with evaporator coils having capillary tube metering devices.
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.
C. REFRIGERANT TUBING AND FILTER DRIER CAUTION: Installation of filter drier in liquid line is required. Connect vapor tubing to fittings on outdoor unit vapor service valve. Connect liquid tubing to filter drier. (See Table 1 and Fig. 9.) Use refrigerant grade tubing.
DEEP VACUUM METHOD The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and liquid water.
NOTE: Install branch circuit disconnect of adequate size per NEC to handle unit starting current. Locate disconnect within sight from and readily accessible from unit, per Section 440-14 of NEC. A. ROUTE GROUND AND POWER WIRES Remove access panel and control box cover to gain access to unit wiring.

4. Close electrical disconnects to energize system. 5. Set room thermostat at desired temperature. Be sure the set point is below indoor ambient and is set low enough to energize desired speed. 6. Set room thermostat to COOL or HEAT and fan control to AUTO or ON as desired.
Adjust charge in both heating and cooling by following procedure shown on charging tables located on pink charging label on back side of access panel. NOTE: Unit is to be charged in high capacity only. Charging in low capacity may cause compressor chattering and possible damage to the compressor.
NOTE: When two-speed unit is operating in low-capacity cool- ing, system vapor (suction) pressure will be higher than a standard single-speed system or high-speed operation. This normal opera- tion is due to the reduced capacity operating with typically larger indoor and outdoor coils.
After termination of a defrost cycle, the outdoor fan delays come on for 20 sec. This allows refrigerant system to recover outdoor coil heat and minimize the “ steam cloud ” effect. I. DEFROST TIME SELECTION The defrost interval can be field selected, dependent on local or geographical requirements.
XIV. FINAL CHECKS IMPORTANT: Before leaving job, be sure to do the following: 1. Ensure that all wiring and tubing is secure in unit before adding panels and covers. Securely fasten all panels and covers. 2. Tighten service valve stem caps to 1/12-turn past finger tight.
