ENVISION SERIES AIR HANDLER INSTALLATION MANUAL

General Installation Information

Refrigeration

The Envision NAH series air handlers are supplied with an expansion device. Once the line set has been brazed into the air handler the txv bulb must be attached to the suc- tion line outside of the cabinet and insulated with foam tape. Be careful not to crush the txv bulb by over-tighten- ing the clamp. The txv supplied has an internal check valve so no external check valve is necessary. The air handler txv should be adjusted initially per TXV Superheat Adjustments table. Check sub-cooling and superheat, refrigerant charge and txv may require further adjustment.

30 minutes after the adjustment is made for the system to stabilize.

3.Once the proper superheat setting has been achieved replace and tighten the seal cap.

Warning – There are 8 total (360°) turns on the superheat adjustment stem from wide open to fully closed. When adjusting the superheat stem counterclockwise (superheat increase) and the stop is reached, any further counterclock- wise turning adjustment will damage the valve.

NOTE: The air handler is factory supplied with a holding charge of dry nitrogen.

TXV Superheat Adjustment Procedure (see figure 4) Txv’s may require adjustment for a specific application.

1.Remove the seal cap from the bottom of the valve.

2.Turn the adjustment screw counterclockwise to increase superheat and clockwise to decrease superheat.

One complete 360° turn changes the superheat approximately 3-4°F. You may need to allow as much as

Charging the System

Refer to IM1592 for charging the system, checking sub-cool- ing/superheat and unit operating parameters. Refer to the Refrigerant Line Sizing table for initial refrigerant charge amounts used with the Envision Split.
