Air-cooled 15 kW Generators

4.Remove the engine air in baffle located on the left- hand side of the battery compartment. Two M6 screws are located on top of the baffle and two M6 screws are located on the inside of the baffle towards the back.

5.Remove the small hose clamp and hose from the fuel regulator. It may be necessary to pry the hose off of the brass fitting using a screwdriver to gen- tly lift up the hose edge.

6.Remove the small brass hose fitting from the regulator casting.

7.Place the small fuel jet, thread side first, into the threaded hole originally occupied by the brass hose fitting (Figure 1.3).

14.It may be necessary to make minor adjustments to the preset adjustment screw settings to achieve maximum power, particularly at higher altitudes. If experiencing problems with the unit produc- ing maximum power, follow the procedure in "Adjusting the Fuel Regulator".

2.1INSTALLATION

Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors:

• Install the unit where air inlet and outlet openings

will not become obstructed by leaves, grass, snow,

etc. If prevailing winds will cause blowing or drift-

ing snow, consider using a windbreak to protect

the unit.

• Install the generator on high ground where water

levels will not rise and endanger it.

• Allow sufficient room on all sides of the generator

for maintenance and servicing. A good rule is to

allow three feet of space on all sides.

• Where strong prevailing winds blow from one

direction, face the generator air inlet openings to

the prevailing winds.

• Install the generator as close as possible to the fuel

supply, to reduce the length of piping.

8.Using a short No. 2 Phillips screw driver, thread the small fuel jet into the regulator casting. Do not over tighten.

9.Apply thread sealant to the threads of the hose fitting and replace it into the regulator body.

10.Re-attach the small hose and hose clamp and tighten as necessary.

11.Replace the engine air in baffle using the four M6 screws.

12.Identify both brass adjustment screws on the regulator.

NOTE:

One adjustment screw can be accessed from the front of the unit and the second can be accessed from the back of the unit enclosure by removing the plastic hole plug. The screw can be turned with a long flat blade screwdriver.

13.To adjust the system to run on LP fuel, turn BOTH adjuster screws 1/2 TURN CLOCKWISE. The system should now be set for maximum power and best perfomance. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE SET PINS FROM THE REGULATOR HOUSING. THIS WILL VOID THE WARRANTY.

Mounted in the transfer switch is relay contact board (Figure 2.1) that can be used to remotely monitor various functions of the generator system.

The contacts are rated as shown below. Failure to fol- low these ratings will cause unit failure.

•Arrangement: SPCT (Form C)

•Ratings: Resistive Load, 4Amp max switching current at 30VDC; 2Amp max switching current at 125VAC

•Wire Range: 26-14Awg

•Terminal tightening torque: 5 in/lb.
