STARTING AIDS
This standby generator is equipped with the following
starting aids that serve to provide quicker, easier
starts under varying climactic conditions.
This generator has been mounted with an engine
coolant heater and a battery charger. These aids are
powered by a normal (utility) power source during
nonoperating periods.
1.9.1 ENGINE COOLANT HEATERS
This unit is equipped with an engine coolant (block)
heater (Figure 1.2), it is powered by a circuit normal-
ly fed by the utility power supply. The heater acts to
heat the engine coolant when the unit is not operat-
ing. This action keeps the engine warm even in cold
weather, thus helping ensure quicker starts. Heated
coolant in the engine rises continuously drawing cold
coolant into the heater, thus making certain of a con-
stant flow of warm coolant through the engine.

1.9.2 BATTERY CHARGERS
All UL units will be fitted with a 12V or 24V, 10 amp
charger. This charger is similar to the one shown in
Figure 1.3.
1.9.2.1 Dual-rate Battery Charger
This SCR-controlled, fully automatic battery charger
has a panel-mounted DC ammeter and voltmeter,
fused input and output circuits, and an automatic
current limiter design. The unit is equipped with
automatic float and equalize control and uses an SCR
to maintain proper charge voltage. This type of sys-
tem precisely monitors the charge rate (Figure 1.3 ).
The charger is rated at 10 amps DC.

STANDBY GENERATOR
INSTALLATION
DANGER
Connecting this generator to an electrical sys-
tem normally supplied by an electric utility
shall be by means of a transfer switch (such as
the Generac "GTS" type transfer switch), so as to
isolate the electric system from the utility dis-
tribution system when the generator is oper-
ating. Failure to isolate the electric system by
these means will result in damage to the gen-
erator and may also result in injury or death
to utility workers due to backfeed of electrical
energy.
If an open bottom is used, the engine-genera-
tor is to be installed over non-combustible
materials and should be located such that
combustible materials are not capable of accu-
mulating under the generator set.
Only qualified, competent installation contractors or
electricians thoroughly familiar with applicable
codes, standards and regulations should install this
standby electric power system. The installation must
comply strictly with all codes, standards and regula-
tions pertaining to the installation.
This genset must be installed on a level surface. The
base frame must be level within two (2) inches all
around.
After the system has been installed, you must
!
not do anything that might render the instal-
lation in noncompliance with such codes,
standards and regulations.
