to check all inputs.
The procedure is as follows:

2. In the SERVICE MENU screen select the SERVICE icon.
3. Enter password and scroll to MANUAL MODE, select YES with the up key.
4. Now scroll to Fan On and select ON with the up key. The fan must be on to
operate loads in this mode. You must turn off the fan and service mode when
completed.
The Compressor 1 and 2 selections are for the ON/OFF and RUN, EVACUATE,
and CHARGE modes.
When user scrolls to the Compressor 1 or 2 positions in the parameters list he
