What is an automatic standby generator? An automatic
standby generator is a back-up electrical system that operates whether you are
at your property or away. It automatically supplies power to essential circuits
of your building within seconds of a utility outage. After utility power returns,
the generator shuts itself off and awaits the next outage. It operates on natural
gas or liquid propane and usually is installed outside at ground level or on the
roof. What will it power? GUARDIAN® generators supply electricity
to the electrical panel circuits of your property through an automatic transfer
switch. You can elect to back up selected emergency circuits or your entire facility.
A GUARDIAN Dealer or electrician can calculate the amperage of items you want
to protect and match it to the appropriate generator system. Our liquid-cooled
models range from 20-150 kW (single and three phase) and are ideal for larger
homes, small businesses and commercial applications. Why should I
buy an automatic standby generator instead of a portable generator? While
portable generators do supply power, an automatic standby generator produces a
higher quality of electricity. It operates automatically and runs a weekly self-test
to ensure proper response to an outage. There are no extension cords to plug in
and no gas tanks to fill. It operates automatically so it protects our property
even when you’re away. When utility power returns, the standby generator shuts
itself off. What’s the difference between air-cooled and liquid-cooled?
Air-cooled units use engines we design and manufacture specifically for our
smaller generators. Volume production helps us to keep cost down, making our air-cooled
generators the most affordable for our customers. They cover essential circuits
and back-up power needs in most residential applications. Liquid-cooled units
use automotive engines for increased horsepower. This makes them ideal for larger
requirements such as whole-house power coverage, larger homes and commercial applications.
Do they have to be maintained? Just like your car’s engine, generators
need periodic oil and filter changes. Many customers rely on GUARDIAN’s preventative
maintenance kits (models up to 45 kW) to satisfy routine maintenance requirements.
Refer to your owner's manual for routine maintenance procedures and schedules.
Kits can be purchased through the business that sold you your GUARDIAN generator.
What is the advantage of an aluminum enclosure? Aluminum is corrosion
resistant, so it prolongs the life and look of the generator, particularly in
salt air communities. What is Whisper-Test™? Whisper-Test
is a feature that reduces noise by 50% during the generator’s weekly self-test
cycle. That makes it as quiet as a car idling in your driveway. The generator
starts up and operates at a reduced speed, lowering sound output by as much as
12 decibels for units that normally run at higher speeds under load. This allows
for near-silent operation in test mode and satisfies all known sound ordinances.
How do I select a generator that’s right for me? (Generator
Size Calculator) The most accurate way is to have a licensed electrician
perform a site survey to determine the size and voltage of the unit to meet your
backup power needs. How long does it take to install an automatic
standby generator? Liquid-cooled generators normally require up to 14
hours, over two days, to install. Because of their additional weight, liquid-cooled
units must be installed on a stronger mounting surface such as a concrete slab.
Note: Time estimates are based on typical applications. Additional time may
be required to run gas conduit or gas piping or to place the unit far from the
incoming gas or electrical service.How much fuel does an automatic standby generator
use? 7-16 kW Air-Cooled 20-45 kW Liquid-Cooled 60-150 kW Liquid-Cooled
Natural Gas (cu ft/hr) 100-250 300-750 960-2061 LP (cu ft/hr) 50-90 120-300
375-830 Please refer to the individual model’s specification sheet for exact
figures. Note: Figures are based on continuous operation at full load.
It is unlikely that the generator will run at full load for an extended period,
therefore, consumption decreases accordingly.What transfer switch do I need?
Liquid-cooled models up to 60 kW require RTS transfer switches (100-400 amps),
while 70-150 kW models require HTS transfer switches (100-800 amps).
Where can I purchase parts? What is the cost of a service/maintenance
contract? Costs are determined by the installing dealer and are based upon
service levels. Cost will also vary based on hourly labor rates in your local
area. What type of oil is recommended? 15W-40 is recommended
for all liquid-cooled units. The oil should be a SAE rated high detergent oil
that meets API Service Class SF requirements for gasoline engines.
Propane tanks are usually rated by pounds. Is there a conversion that can be applied
to the fuel consumption numbers? Yes. For general conversion, propane weighs
4.24 pounds per gallon. 1 lb. = 8.58 cu. ft. 1 gallon = 36.39 cu. ft.
Where do I go to have warranty repairs performed? Any Authorized
GUARDIAN Service Center can perform warranty service. Where
is my Generator made? GUARDIAN generators are made in the United States. Manufactured
in Wisconsin by Generac Power Systems Inc., we design and build our complete product
from the controls to the enclosures. This ensures that our products are built
to our highest standards.

The transfer switch monitors utility power and signals
the generator to start when utility power is interrupted. When utility power returns,
the transfer switch returns the electrical load from the generator back to the
utility. This ensures your most important electrical loads are powered, within
seconds, even when you’re away. The transfer switch is the difference
between a truly automatic generator set and just another generator. No toggles
to flip, no knobs to turn, no extension cords to run when you lose utility power.
You will have the comfort and peace-of-mind knowing that your GUARDIAN standby
generator does everything for you... automatically. Suggested Transfer
Switch When choosing a transfer switch, you must match or exceed the generator
output amperage. The following table illustrates a suggested transfer switch to
use with each generator. The transfer switch to be used is based on the kW rating
and voltage of the generator. All GUARDIAN transfer switches are UL 1008 Listed
to meet safety and performance standards. kW Engine 120/240, 1Ø
