TSTAT0201CW Recommended (sold separately) CSA6 SoftSound SXC 2600 Product Specifications This product has been designed and manufactured to meet ENERGY STAR criteria for energy efficiency when matched with appropriate coil components. However, proper refrigerant charge and proper air flow are critical to achieve rated capacity and efficiency. Installation of this product should follow the manufacturer s refrigerant charging and air flow instructions. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten equipment life. Use of the AHRI Certified TM Mark indicates a manufacturer s participation in the program.

The factory charge for lineset 9 oz. When using other length or diameter liquid lines, charge adjustments are required per the chart above. Charging Formula: [(Lineset oz/ft x total length) (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4 liquid line. What charge adjustment is required? Formula: (.27 oz/ft x 15ft) (9 oz) = (-4.95) oz. Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16 liquid line. What is the charge adjustment? Formula: (.40 oz/ft. x 45ft) (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system NOTE: Conditions must be favorable for charging by subcooling method. Indoor temperature must be 70_F to 80_F (21.1_C to 26.7_C), and outdoor temperature must be 70_F to 100_F (21.1_C to 37.8_C). If outside these conditions, adjust charge for long line sets by weigh- in method. LONG LINE APPLICATIONS An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units. For Air Conditioner systems, the charts below shows when an application requires a TXV and long line accessories due to lineset length. For Air Conditioner systems, the charts below show when an application is considered Long Line: AC with Refrigerant Long Line Description ft (m) Beyond these lengths, a TXV is required Total Length Outdoor Unit Above or Below Indoor Unit TXV required beyond 50 ft. (15.2 m) TXV required beyond 20 ft.
