APPLICATION DATA SHEET General Piping Recommendations and Refrigerant Line Length for Split-System Air Conditioners and Heat Pumps GENERAL GUIDELINES The following guidelines apply to the application on either factory line sets or field fabricated tubing for cooling only and heat pump This Split-System (Air Conditioning Condensing/Heat systems: Pump) unit is one component of an entire system. As such it requires specific application considerations with • Many service problems can be avoided by taking adequate regard to the rest of the system (air handling unit, duct precautions to provide an internally clean and dry system design, refrigerant piping and control scheme). and by using procedures and materials that conform with Failure to properly apply this equipment with the rest of established standards. the system may result in premature failure and/or • The lines should be installed so that they will not obstruct reduced performance/increased costs. Warranty service access to the indoor coil, air handling system or filter. coverage specifically excludes failures due to improper Install the lines with as few bends as possible. Care must be application and UP specifically disclaims any liability taken not to damage the couplings or kink the tubing. Care resulting from improper application.
