4 Do not open or mutilate the battery . Released electrolyte can be toxic and harmful to the skin and eyes. The battery represents a risk of high short-circuit current. When working on the battery , always remove watches, rings or other metal objects, and only use tools that have insulated handles. V ented Batteries The electrolyte is a diluted sul[...]

5 Locate the mounting pad as close as possible to the transfer switch and fuel supply . Leave adequate room around the pad for service access (check local code) and place the pad high enough to keep rising water from reaching the generator . Choose an open space that will provide adequate and unobstructed airow . Place the unit so air vents won?[...]

6 Make sure the lifting equipment you’ll be using has sufcient capacity to safely handle the weight of the generator . Use nylon lifting straps and connect them to the lifting eyes on each corner of the base frame to avoid damaging the enclosure. Set the generator onto the pad so that the gravel bed extends several inches beyond the generator [...]

7 Check the engine oil, and if necessary , add enough of the recommended oil to bring the level up to the FULL mark on the dipstick. Be careful not to overll the crankcase. The generator was congured for natural gas operation at the factory . Switching over to LP vapor is a simple procedure. On models with the V -T win engine, simply ip th[...]

8 Replace the fuel hose and clamp. Then reconnect the wires to the solenoid. Finally , insert the plastic plug that came with the generator into the hole on the bottom of the air cleaner base. Both natural gas and LP vapor are highly volatile substances, so strict adherence to all safety procedures, codes, standards and regulations is essential. Ga[...]

9 When connecting the gas line to the generator , use a short section of UL Listed or AGA- approved exible fuel line in accordance with local regulations. The purpose of the exible fuel line is to ensure that vibration from the generator does not cause a gas leak at one of the connection points, so it’ s important that the line be installed[...]

10 Drill a 1¾ inch hole and feed the conduit through the hole. Remove the knockout in the back of the connection box, feed the wires through the back of the box and secure the conduit with the lock nut. Seal the hole with silicone caulk. Don’t for get to caulk the hole inside the house as well. Mount the connection box so that it completely cove[...]

1 1 Before beginning any installation, make sure power is shut OFF to the main distribution panel and carefully read the Installation Guide that came with your transfer switch. The distributed load center switch must be mounted close enough to the main distribution panel to accommodate the two-foot, pre-wired conduit. Make sure no water or corrosiv[...]

12 When three-conductor wiring is used, two 120 volt circuits will often share the same neu tral wire. T o avoid overloading the neutral, you should either move BOTH of the circuits that share the neutral or don’t move either of them. When moving two circuits with a shared neutral, they should be connected to adjacent positions (one above the oth[...]

13 Install a 2-pole breaker in the distribution panel to protect the transfer switch. The required Amp rating of the breaker depends on which transfer switch you’re using, so refer to the Installation Guide before purchasing the breaker . Install the breaker in two adjacent empty slots (one above the other) in the main panel. When all emergency c[...]

14 Locate the transfer handle and insert the metal end into the slot in the main contactor assembly . Pull the handle DOWN to move the main contacts to the standby power (generator) position. NEVER OPERA TE THE TRANSFER SWITCH MANUALL Y WHEN LOADS ARE CONNECTED. Put the generator ’ s mode switch in MANUAL to start the engine. Allow the engine to [...]

15 Use the transfer handle to move the main contacts in the transfer switch to the UP (utility) position. Switch the 2-pole breaker ON in the distribution panel. Now switch the generator ’ s main breaker ON and put the mode switch in AUTO. Shut OFF utility power and make sure the generator starts automatically . If everything worked properly , sw[...]

After the engine has completed its cool down cycle and shut down, shut OFF utility power again. When the generator is supplying power to the transfer switch, move the breakers in the switch to the ON position one at a time until the generator has accepted the entire emergency load. W ith the generator carrying the entire emer gency load, re-check g[...]

Shut OFF utility power again. The generator should start and the entire emergency load should transfer to the generator . Close the main breaker to restore utility power and allow the engine to cool down and shut itself OFF . W ith the mode switch in AUTO, press the EXERCISER switch. Hold it down for at least 10 seconds and release. The generator s[...]
