Installation Manual

INITIAL START-UP (NO LOAD)

Begin testing the system without any electrical loads connected, as follows:

1.Set the AUTO/OFF/MANUAL switch to OFF.

2.Set the generator’s main circuit breaker to its OFF (open) position.

3.Install the 15 Amp fuse in the control panel.

4.Set the AUTO/OFF/MANUAL switch to MANUAL.

NOTE: When the Home Standby Generator is started for the very first time, it will require that air in the gaseous fuel lines be purged.This may take a few minutes.

5.DO NOT crank engine for more than 15 seconds, then pause for 15 seconds to reduce heat in the starter.

6.Repeat process until engine starts.

7.Listen for unusual noises, vibration or other indications of abnormal operation. Check for oil leaks while the engine runs.

8.Let the engine warm up for about five minutes to allow internal temperatures to stabilize.Then, set the generators main circuit breaker to its ON (or closed) position.

9.Connect an accurate AC voltmeter and a frequency meter to check generator output at the load side of the circuit breaker.Voltage should be 239-250 Volts, frequency should be 62.0 - 62.5 Hz.

NOTE: If either parameter is outside these ranges, perform the Engine Adjustments described on page 14.

10.Check generator output between one of the generator connection lugs and the neutral lug, then between the other generator connection lug and the neutral lug. In both cases, voltage reading should be between 121-126 Volts.

11.Set the AUTO/OFF/MANUAL switch to OFF. Engine should stop.

IMPORTANT: DO NOT proceed until you are certain that generator AC voltage and frequency are correct and within the stated limits.To obtain the proper generator frequency, see Engine Adjustments on page 14.

Engine Adjustment

There are regional variances in the composition of natural gas. Each HSG unit is adjusted at the factory for NG operation. If the generator output voltage or frequency measured during Initial Start-Up (paragraph #9) is outside the listed ranges, the combustibility of the gas supplied at the installation site may be substantially different.

To adjust the engine for this difference, proceed as follows.

1.Remove the Air Intake and Control Panel access doors.

2.Remove the three M5 sheet metal screws that hold the control panel wiring cover to the air intake guard (Figure 13).

Figure 13 — Accessing Back of Control Panel

3.Connect an accurate frequency meter to the load side of the main circuit breaker (on the back of the control panel).

4.Ensure that the 15 Amp fuse is installed.

5.Set the generator’s main circuit breaker ON.

6.Set the AUTO/OFF/MANUAL switch to MANUAL. When the engine starts, allow it to warm up for two minutes.
