Guardian Technologies 04164-3, 02010-2 SUMMER/WINTER Heat Riser System, Stopping the Generator

Section 2 – Operation

NOTE:

If starting from the generator control panel, turn OFF loads by setting the generator’s main circuit breaker to the OFF (or OPEN) position. If starting from a remote panel, turn OFF loads using the means provided in the vehicle (such as a main circuit breaker). Electrical load circuits will be turned ON after the generator has started, stabi- lized and warmed up.

2.If the engine has not been started in more than two weeks, press the Fuel Pump Primer switch and hold it for about 10 to 15 seconds to prime the fuel system. However, if the engine is warm, skip Step 2.

3.Hold the engine Start/Stop switch in the START position to crank the engine. Release the switch when the engine starts.

If the engine does not start after it has been cranking for 15 seconds, release the Start/Stop switch and try again. Holding the switch for longer than 15 seconds can damage the starter motor.

4.Let the engine run at no-load for a few minutes to stabilize and warm up.

5.Turn ON electrical loads using the means pro- vided (such as a main circuit breaker or transfer switch).

2.8SUMMER/WINTER HEAT

RISER SYSTEM

Under certain weather conditions, it is possible for ice to form in the venturi area of the carburetor. This condition can be very dangerous because it can pre- vent the governor system from functioning properly, which results in a “runaway” engine.

The most common weather conditions leading to this problem are temperatures in the range of 25° F to 35° F (-4° C to 1.7° C), along with high humidity. This ice formation also can be attributed to the load being applied during these weather conditions. Generators running with no-load or light loads applied usually have the most problems.

The Summer/Winter Lever (Figure 2.3) should be in the WINTER position for ambient temperatures below 40° F (4.4° C) and in the SUMMER position for ambient temperatures above 40° F (4.4° C).

2.6STOPPING THE GENERATOR

1.Turn OFF all electrical loads using the means provided (such as a main circuit breaker or transfer switch).

2.Let generator run at no-load for a few minutes, to stabilize internal engine generator temperatures.

3.Place the Start/Stop switch in its STOP position.

2.7APPLYING LOADS TO GENERATOR

When applying electrical loads to the generator, observe these guidelines:

•Before applying electrical loads, let the generator stabilize and warm up for a minute or two.

•DO NOT overload the generator.

‹2.7.1 LETTING THE ENGINE STABILIZE

The generator supplies correct rated voltage only at the proper governed speed. Some electrical appli- ances may be extremely sensitive to voltage. Incorrect voltages can damage such appliances.

If electrical loads are applied at reduced operating speeds, such loads imposed on the engine when suf- ficient power is not available may shorten engine life. Never turn ON electrical loads until after the generator engine has started and stabilized at no-load.

When the heat riser is in the SUMMER (down) posi- tion (Figure 2.2), air is drawn into the air cleaner from the upper intake tube.

When the heat riser is in the WINTER (up) position, air is drawn from the lower intake tube, which is positioned to draw the heated air near the exhaust manifold.

To prevent carburetor icing, the owner/operator should physically position the heat riser to the prop- er position dependent on the temperature.
