High Altitude Operation - Yamaha EF2200iS Owner's Manual

Operation
NOTICE
• Do not overload. The total load of all electrical appliances must not exceed the
total supply range of both AC and DC of the generator. Overloading will damage
the generator.
• When supplying precision equipment, electronic controllers, PCs, electronic
computers, microcomputer-based equipment or battery chargers, keep the gen-
erator a sufficient distance away to prevent electrical interference from the
engine. Also ensure that electrical noise from the engine does not interfere with
any other electrical devices located near the generator.
• If the generator is to supply medical equipment, advice should first be obtained
from the manufacturer, a medical professional or hospital.
• Some electrical appliances or general-purpose electric motors have high start-
ing currents, and cannot therefore be used, even if they lie within the supply
ranges given in the above table even though you use the boost mode switch.
Consult the equipment manufacturer for further advice.

High altitude operation

This engine may require a high altitude carburetor kit to ensure correct engine operation
at altitudes above 4000 ft. (1219 meters). If you operate your engine at altitudes above
4000 ft. (1219 meters) consistently, have your local Yamaha dealer perform the neces-
sary carburetor modification. This engine should be operated in its original configuration
below 4000 ft. (1219 meters) as damage may occur if high altitude carburetor kit is
installed and operated below 4000 ft. (1219 meters).
