Installation & Operation Manual - Phase-A-Matic, Inc.

Physical Location The mounting location of the system is important. It should be installed in an area that is
protected from direct harmful gases or liquids, dust, metallic particles, shock and vibration.
It should be installed in an outdoor location so the exhaust fumes are vented to the atmosphere.
WARNING: An open bottom stationary engine generator set must be installed over noncombustible
materials and shall be located such that it prevents combustible materials from accumulating
under the generator set.
Outdoor Location with Baldor Supplied Enclosure
If the generator is installed outdoors there should not be a cooling problem. The factory installed
enclosure is designed to keep out undesirable weather elements while providing cooling and
ventilation. It should be installated on a concrete pad with at least thirty−six (36) inches
clearance on all sides for air flow.
1. For effective cooling and maintenance, the system should be installated on a concrete pad
with at least thirty−six (36) inches clearance on all sides for air flow and service access.
2. Installation should prevent water levels from reaching the generator. Drainage must be
adequate to keep concrete pad free from standing water.
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If
these items pose a problem, consider building a small fence or other break to protect
the unit from accumulation of debris.
Indoor Location Open Frame Configuration
When the Generator is installed in a building it is essential to provide:
1. Adequate control and exhausting of the heated air.
2. An adequate and constant supply of incoming cooling air.
3. Adequate control and discharge of the engine’s hot exhaust gases.
4. Adequate ventilation of the building when the engine shuts down.
Several other factors should be carefully evaluated when selecting a location for installation:
1. For effective cooling and maintenance, the system should be mounted on a flat, smooth,
non-flammable level surface. A concrete pad is ideal and provides a secure installation.
2. Installation should prevent water levels from reaching the generator. Drainage must be
adequate to keep concrete pad free from standing water.
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If
these items pose a problem, consider building a small fence or other break to protect
the unit from accumulation of debris.
4. Installation should place the generator as close as possible to the fuel supply and
transfer switch.
5. At least forty−eight (48) inches clearance must be provided on all sides for air flow.
6. Maximum Ambient temperature is 122°F (50°C).
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. For 8−12KW we recommend an
exhaust fan of at least 2000 CFM.
Note: The exhaust fan must not be located where it could easily become blocked by leaves,
snow, water, debris, etc.
