GENERATOR INSTALLATIONS
INSTALLATION
We strongly recommend that you have the installation performed by a
licensed electrical or mechanical contractor. They have the tools, the
know-how and an understanding of governing regulations and local codes.
Their expertise will save you money in the long run and help keep you
safe.
If you
chose to perform the installation yourself, please do your
homework before tackling the job and obtain the proper permits required
by your local jurisdiction.
All
gensets have some basic requirements. Each brand and model has unique
installation requirements. Also, it is extremely important to have all
relative codebooks for reference and to adhere to them strictly. Most
important of all, your system must be inspected before getting it up and
running.
LOCATION
Ensure the following elements are present:
-
Air inlet
for combustion and engine cooling.
-
Outlets for
exhaust and hot air cooling.
-
Fuel,
battery and AC electrical connections.
-
Remember to
monitor for carbon monoxide!
-
Rigid,
level mounting platforms (many sets are already mounted on a steel
skid base).
-
Open
accessibility for easy service.
-
Isolation
from living space. Keep noise and exhaust away from occupied areas.
-
Space and
equipment to extinguish a fire. Minimize the possibility of fire
danger.
-
Remember,
generator units move on their vibration mounts. Allow clearance to
compensate and use flex- joints on all lines
and connections.
EXHAUST SYSTEMS
The
exhaust system may need to be covered with insulated material to prevent
fire resulting from contact with combustible materials. We
recommend a heat blanket over exhaust outlets to reduce the heat
radiated from the exhaust and to ensure personal safety.
Some
insulation materials are best left to professionals with the proper
equipment. Keep the piping away from combustible materials including
walls. A seamless, stainless steel flexible joint must be used between
the generator set and the exhaust system to prevent metal fatigue. Do
not use the exhaust manifold to support the exhaust system - the weight
can cause manifold failure. Exhaust pipe hangers are readily available.
FUEL SYSTEM
Extreme
care should be taken in designing and installing the fuel system to
prevent fire danger. Fuel lines should have as few connections as
possible and be routed to prevent damage. Keep lines away from hot
engine or exhaust components. The lines should be no smaller than the
inlet and outlet on the engine. Support fuel lines with clamps as
needed to help prevent metal fatigue from vibration. The fuel tank
should be level with or below the set to prevent siphoning in the event
of a line failure. Remember to check the lift capacity of the engine
fuel pump and stay within its limits. If the set is higher than the
tank, an auxiliary fuel pump may be required.
To
prevent water ingestion, fuel should be drawn out of the top of the tank
with the pick-up extending to no more than two inches from the bottom.
Fuel storage tanks must have leakage protection. Above ground tanks are
recommended. Check your local codes before installing a tank to make
sure it meets local code. The safest tanks are double walled with
alarms. These alarms are simple and well worth the investment to avoid
a possible fuel spill and significant clean-up costs. If the tank is
mounted above the generator set, use a fuel shut-off valve. This will
allow you to work on the fuel system without the fuel-siphoning out. It
will also allow you to cut-off fuel flow in the event of line breakage.
A high
quality, fuel/water separator filter should be mounted as close to the
generator set as possible. Because of its explosive nature, gasoline
fuel systems have special requirements; see your tank supplier for
complete information.
COMBUSTION AND COOLING AIR
The
generator set requires air for combustion and cooling. A radiator and a
“pusher” engine fan cool the generator engine temperature. An internal
fan cools the generator.
Indoor Mounting
The
room, or space, in which the generator operates, should not exceed 100F.
We recommend keeping it under 85F if possible. Generator
installations require an intake for cool, clean air and an outlet vent
for hot air. Since the size of the space affects the room temperature
(the smaller the space the generator runs in, the higher the room
temperature is likely to be), smaller spaces may require ducting. Other
factors, which will affect the room temperature include generator size
and the outside air temperature or climate. In an indoor installation,
increasing these vent sizes may cool the room down to acceptable
levels. If this doesn't provide sufficient cooling, ducting may be
required to ensure “positive” airflow. Simply stated, positive airflow
is cool, clean air in – hot air out, as opposed to circulating hot air
inside the room. Generator cooling fans move moisture as well as air.
Moist air is corrosive to a generator unit's copper windings. Make sure
air inlets are positioned to minimize moisture intake.
OUTDOOR
MOUNTING
The room, or space, in which
the generator operates, should not exceed 38C (100F). We
recommend keeping it under 30C (85F) if possible. Generator
installations require an intake for cool, clean air and an outlet vent
for hot air.
Since the size of the space
affects the room temperature (the smaller the space the generator runs
in, the higher the room temperature is likely to be), smaller spaces may
