4.1 OPERATE TRANSFER SWITCH
Operate the transfer switch at least once each month. This can be
done by performing a NORMAL TEST of the system. The System
Test switch only simulates failure of the UTILITY power source,
therefore, service will be interrupted only during the actual transfer
of the load.
4.2 CLEAN AND INSPECT TRANSFER
SWITCH
Protect the transfer switch against construction grit, metal chips,
excessive moisture and other harmful dirt at all times. At least
once each year, turn OFF all power supplies to the switch, then
brush and vacuum away dust and dirt that has accumulated inside
the enclosure. After cleaning, inspect the transfer switch carefully.
Look for evidence of arcing, burning, hot spots, charring and other
damage. If any of these are found, have the switch assembly
checked by an authorized service technician.
4.3 LUBRICATION
Operating parts inside the transfer mechanism have been properly
lubricated at the time of assembly. Under normal conditions no
additional lubrication should be required. The service technician
should lubricate all recommended points whenever major transfer
mechanism components are replaced.
Use only specified greases to lubri-
cate contactor parts. DO NOT USE ANY
SUBSTITUTES.
