Generac Power Systems NP-50G Series User Manual

Place the lever in the “Winter” position (25 - 30°F), so the hole
in the plastic tube is covered and the aluminum tube is opened.
As mentioned previously, the end of the aluminum tube is
positioned very close to the exhaust manifold. As the engine
is running and the exhaust system heats up, heated air is drawn
through the aluminum tube, which helps to prevent ice from
forming on the carburetor.
■ DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of your gen¬
erator on the generator data decal (see “Identification Record”
on Page 3).
Applying electrical loads in excess of the unit’s rated capac¬
ity will cause the engine-generator to automatically shutdown.
To avoid overloading, add up the wattage of all connected elec¬
trical lighting, appliance, tool and motor loads. This total should
not be greater than the generator’s rated wattage capacity.
• Most lighting, appliance,, tool and motor loads indicate their
required watts on their nameplate or data plate. For light
bulbs, simply note the wattage rating of the bulb.
• If a load does not show its rated wattage, multiply that load's
rated VOLTS times AMPS to obtain WATTS.
• Induction type motors (such as those that run the vehicle’s
furnace fan, refrigerator, air conditioner, etc.) need about 2-
1/2 time more watts of power for starting than for running
(for a few seconds during motor starting). Be sure to allow
for this when connecting electrical loads to the generator.
First, figure the watts needed to start electric motors in the
system. To that figure, add the running wattages of other
items that will be operated by the generator.
• Do not apply heavy electrical loads for the first two or three
hours of operation.
ADDITIONAL INFORMATION
This section discusses some the the engine protective devices,
overload protection and breaking in a new generator.
■ AUTOMATIC LOW OIL PRESSURE
SHUTDOWN _
The engine is equipped with a normally-closed (N.C.) oil pres¬
sure switch (Figure 5). Engine oil pressure holds the switch
open during cranking and operation. Should oil pressure drop
below a pre-set level, the switch contacts close and the engine
automatically shuts down.
