4.2 High altitude operation
At higher altitudes, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase. Power output will decrease 3.5% for each 1000 feet (305 m)
above sea level.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor. If
you always operate the generator at altitudes higher than 5000 feet (1500 m) above sea level, have your
authorized dealer install a high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1000
feet (305 m) increase in altitude. The affect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
■Operation of the generator at an altitude lower than the carburetor is jetted for
may result in reduced performance, overheating, and serious engine damage
caused by an excessively lean air/fuel mixture.
■Be sure to have any modification reversed at lower altitudes.
Temperature
High temperature adversely affects generator operation. Generator performance will decrease 1% for each
10°F (5.5°C) increase in temperature above 85°F (29°C). The normal operating range of this generator is
-20° to 113° F (-29° to 45°C).
■Do not operate the generator when the ambient temperature is below -20°F
(-29°C).
■Do not operate the generator when the ambient temperature exceeds 113°F
(45°C).

15 PH1000i OM revision 2010-10-07
4.3 Generator use
Be sure to ground the generator when loads are connected.
■To prevent electrical shock from faulty appliances, the generator should be
grounded. Connect a length of heavy cable between the generator's ground
terminal and an external ground source.
■Connections for standby power to a building's electrical system must be made by
a qualified electrician and must comply with all applicable laws and electrical
codes. Improper connections can allow electrical current from the generator to
back feed into the utility lines. Such back feed may electrocute utility company
workers or others who contact the lines during a power outage. When utility power
is restored the generator may explode, burn, or cause fires in the building's
electrical system.
■Do not connect the generator to an automatic transfer device. Severe damage to
the inverter module may result.

16 PH1000i OM revision 2010-10-07
■The total wattage of all appliances connected must be considered.
■Do not exceed the current limit specified for any one receptacle.
■Do not connect the generator to a household circuit. This could cause the
damage to the generator or to electrical appliances in the house.
■Do not modify or use the generator for other purpose than it is intended for. Also
observe the following when using the generator.
■Do not connect an extension to exhaust pipe.
■When an extension cable is required, be sure to use a rubber sheathed flexible
cable.
■When an extension cable is required, make sure you use the proper size and
length.
16 Gauge Cords- Any 16 gauge cord between 0 and 100 feet long will adequately handle
tool and appliance loads up to 10 amps.
14 Gauge Cords- a 14 gauge cord between 0 and 50 feet long will adequately handle loads
between 10 and 15 amps.
12 Gauge Cords- If your load is between 10 and 15 amps and the length of the cord is 50
to 100 feet, you need a 12 gauge cord to safely power any tool..
■Keep the generator away from other electric cables or wires such as commercial
power supply lines.
■The DC receptacle can be used while theAC power is in use. If you use both at
the same time, be sure not to exceed the total power forAC and DC.
■Most appliance motors require more than their rated wattage for start-up.
