DISCONNECT
When installing units, provide a disconnect switch of adequate
size per NEC (National Electrical Code). Disconnect sizing data is
provided on the unit informative plate. Locate on unit cabinet or
within sight of the unit per national or local codes. Do not cover
unit informative plate if mounting the disconnect on the unit
cabinet.
UNITS WITH FACTORY-INSTALLED NON-FUSED
DISCONNECT
The factory-installed option non-fused disconnect switch (NFD) is
located in the main control box. The manual switch handle and
shaft are shipped in the control box and must be mounted on the
corner post adjacent to the control box (see Fig. 46). Note that the
tape covering the hole for the shaft in the corner post must be re-
moved prior to handle and shaft installation.
To field install the NFD shaft and handle:
1. Open the control box panel.
2. Make sure the NFD shipped from the factory is at OFF posi-
tion (the arrow on the black handle knob or on the silver
metal collar is at OFF).
3. Insert the shaft with the cross pin on the top of the shaft in the
horizontal position.
4. Measure the tip of the shaft to the outside surface of the cor-
ner post to be 0.88 inches.
5. Tighten the locking screw to secure the shaft to the NFD.
6. Turn the handle to the OFF position with red arrow pointing
at OFF.
7. Install the handle on to the corner post vertically with the red
arrow pointing up.
8. Secure the handle to the corner post with (2) screws and lock
washers supplied.
