Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and
regulations.
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents
for damage.
This standby generator set has been factory sup-
plied with a weather protective enclosure that is
intended for outdoor installation only.
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a trans-
fer switch. The transfer switch must effectively
isolate the electrical system from the utility dis-
tribution system when the generator is operat-
ing (NEC 700, 701 and 702). Failure to isolate an
electrical system by such means will result in
damage to the generator and also may result in
injury or death to utility power workers due to
backfeed of electrical energy.
If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage on
the freight bill or affix his or her signature under the
consignor's memo of loss or damage.
If a loss or damage is noted after delivery, separate
the damaged materials and contact the carrier for
claim procedures.
“Concealed damage” is understood to mean damage
to the contents of a package that is not in evidence at
the time of delivery, but is discovered later.
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator pres-
ent to monitor engine conditions. For that reason, the
engine is equipped with the following systems that
protect it against potentially damaging conditions:
1. Low Oil Pressure Sensor 3. Overcrank
2. High Temperature Sensor 4. Overspeed
There are LED readouts on the control panel to indi-
cate that one of these faults has occurred. There is
also a “System Set” LED that is described below.
1.3 SYSTEM SET LED
The “System Set” LED is lit when all of the following
conditions are true:
1. The AUTO/OFF/MANUAL switch is set to the
AUTO position.
2. The utility voltage being supplied to the unit is
being sensed by the Control PCB. If the utility
sense voltage is not connected to the unit or if it
is below 168 volts AC, then the system set light
will flash rapidly. This indicates that if the
AUTO/OFF/MANUAL switch is placed in the Auto
position , the generator will start.
3. The “Not In Auto” dip switch is set to the OFF
position on the control board.
4. No alarms are present, for example, low oil pres-
sure, high temperature, etc.
