TROUBLESHOOTING
NOTE: Before troubleshooting, familiarize yourself with the
START-UP and CHECKOUT procedures.
Troubleshooting of components necessitates
opening the electrical control box with the power
connected to the unit. Use extreme care when
working with the live circuits! Check the unit name-
plate for the correct line voltage and set the volt
meter to the correct range before making any con-
tact with line terminals.
