*See Section 5.11 for proper DIP switch selection.
The following figures show the typical wiring diagrams with (-)HPN air handler and (-)ARL con-
densing unit. Cooling and heat pump airflows may need to be adjusted for homeowner comfort
once the system is operational.
*If maximum outlet temperature rise is desired, it is recommended that W1 and W2 be jumpered together.

Application Guidelines
1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01 -in. wc.
2. Minimum outdoor operation air temperature for cooling mode without low-ambient operation accessory is 55°F (12.8°C).
3. Maximum outdoor operating air temperature is 125°F (51.7°C).
4. For reliable operation, unit should be level in all horizontal planes.
5. Use only copper wire for electric connections at unit. Aluminum and clad aluminum are not acceptable for the type of connector
provided.
6. Do not apply capillary tube indoor coils to these units.
7. Factory – supplied filter drier must be installed.
