and press the SERVICE MODE key to display the first service screen.
Refer to the latest edition of the CGAF-PTG manual for the SERVICE
TEST screens and programming instructions.
3. Use Table 10 to program the condenser fans for operation by scrolling
through the displays. All of the condenser fans can be programmed to be
"On", if desired. Verify proper fan rotation for VFD's with bypass.
Refer to Figure 22 for the condenser fan locations and the Human Inter-
face designator.

WARNING
Rotating Components!
During installation, testing, servicing and troubleshooting of this product
it may be necessary to check rotating components. Have a qualified or
licensed service individual who has been properly trained in handling
exposed rotating components, perform these tasks. Failure to follow all
safety precautions when exposed to rotating components could result in
death or serious injury.
Make sure all personnel are standing clear of the unit before proceeding.
The system components will start when the designated TEST is initiated.
5. Press the TEST START key to start the test. Remember that the delay
designated in Step 4 must elapse before the fans will begin to operate.

tion. The direction of rotation is indicated by an arrow on the fan hous-
ings. Check the condenser fans for clockwise rotation when viewed from
the top.
If all of the fans are rotating backwards;
A. Press the STOP key at the Human Interface Module in the unit control pan-
el to stop the fan operation.
