Secure the Generator
Six (eight for the GLC125) mounting bolts in the base frame secure the generator to the shipping
pallet. Remove these bolts, lift the generator and remove the shipping pallet. Secure the
generator to the concrete pad using

anchor hardware (not provided) in the base frame
mounting holes. See Figure 3-2. Anchor bolts must be long enough to extend through the
generator mounting frame.
Engine Cooling A sufficient flow of clean, cool air is required for combustion and to dissipate the heat produced
by the engine. Approximately 60% of the heat value of the fuel used is given off as heat (cooling
air and exhaust).
The air that will cool the engine must be brought in from outside the building. A sufficient air–flow
of rate “Cubic Feet per Minute” (CFM) will allow the incoming fresh air to cool the engine. This
requires a power ventilation system of sufficient CFM to be located at the highest possible point
of the building to exhaust hot air and draw in cool fresh air.
Note: The exhaust fan must not be located where it could easily become blocked by leaves,
snow, water, debris, etc.
It is recommended that the cool air intake have at least three (3) times the cross–sectional area
of the power ventilation system. It is also recommended that the cool air intake be located as
close as possible to the top of the generator set.
The exhaust fan must be connected to the AC power terminals of the generator set so that when
the generator set starts it will provide immediate cooling air flow. The fan will operate until the
generator set stops. To test the ventilation system, do the following:
Ventilation Test
1. Place a thermometer as close to the cool air intake of the engine’s blower housing as
you can without allowing the thermometer to touch any material surface.
2. Place another thermometer outside of the building or compartment in the open air
(Keep the thermometer out of direct sunlight or any other heat sources).
3. Run the engine under maximum load for an extended period of time (at least one hour).
4. The temperature difference between the two should not exceed 15 degrees F.
Note that opening any door, window or other opening can upset the air–flow pattern and result in
a significant reduction in the cooling air–flow across the generator set. This may result in
overheating, fire, or explosion. To find out if this is true with your specific application run the
Ventilation Test with all doors and windows closed. Then repeat this test with different doors and
windows open, and eventually with all the windows and doors open. If any of these tests result in
a temperature difference in excess of 15
°
F, you must not run the generator set under those
specific conditions.
