APPLICATION DATA (cont)

j)Elevated con®guration Ð Indoor unit installed above the outdoor unit (see ®gure at right):

·If there is over 25 ft of lift, a bi¯ow (538D only) or standard solenoid valve is required in the liquid line.

·The maximum elevation difference is 65 ft, and the maximum equivalent ft of piping is 200.

·Install an inverted trap in the vapor line. The top of the trap must be above the top of the fan coil. This prevents the refrigerant from collecting in the vapor line.

k)Lowered con®guration Ð Indoor unit installed below the outdoor unit (see ®gure at right):

·For lines shorter than 100 ft, no solenoid valve is required in the liquid line. For lines over 100 ft, in- stall a bi¯ow (538D only) or standard solenoid valve in the liquid line.

·The maximum elevation difference is 150 ft, and the maximum equivalent ft is 200.

l)Additional charge Ð The unit should be charged by weighing in the appropriate charge. Add charge based on the actual length of line which is over 25 ft of liquid line. Add .58 oz of refrigerant per 1 ft in- crease over the 25 ft line to the charge listed in Sys- tem Piston Guide and Refrigerant Charges table on page 21.

NOTE: This only applies to systems where the piston is located at the indoor unit (538A018,024 and 538D018,024).

12.Group control

The 619E fan coil units may be group controlled from a single timeclock or energy management system by inter- rupting the 24-v power to the control board.

13.Thermistors (Heat Pump Systems Only)

Thermistors are used on both indoor and outdoor units to determine operating conditions. Proper thermistor location is critical to unit operation. All thermistors have identical re- sistance values. See Thermistor Equivalence charts on typical system wiring schematics (pages 24-27).

Thermistor cable assemblies are provided with fan coil units to run between indoor and outdoor units. High-voltage

and thermistor cable assemblies should not touch each other, and cable runs may be extended up to 200 ft.

14.Wiring

Use only copper wires from the disconnect to the unit ter- minal block. Aluminum and copper-clad aluminum wires are not acceptable.

All duct-free split systems (except the 009,012 outdoor units) provide 24-v power for the outdoor unit in the duct- free fan coil. The 009,012 outdoor units systems use high- voltage controls.

The 009,012 outdoor units system fan coil units must have power wires run from the outdoor condensing unit to the in- door unit to prevent out-of-phase wiring.

15.Air throw

Refer to Air Throw Data table below for system air throw

capabilities.
