Stopping the Unit at Compartment:
1. Open the compartment housing using instruc-
tions To Open the Unit on page 10.
2. Depress and hold the start-stop switch on the
control to STOP. Release after the generating set
stops.
3. Close the compartment housing using instruc-
tions To Close the Unit on page 11.
LOW TEMPERATURE CONDITIONS
1. Use a light weight oil as shown in the PERIODIC
MAINTENANCE section. Change oil only when
the engine is warm.
Failure to use a lighter weight oil in cold weather results In
hard cranking and a chance the unit won't start.
2. Gasoline Only: Use fresh fuel and keep the fuel
tank full. Afulltank prevents moisture condensa-
tion.
3. Keep the fuel system clean.
4. Exercise the generating set frequently (see Exer-
cising).
TO REMOVE LOAD
After normal power returns, transferthe load from the
generating set to the commercial power source with
your manual or automatic transfer switch. See the
instructions supplied with the transfer switch. To
stop the generating set, see To Stop the Unit below.
TO STOP THE UNIT
Before stopping the unit, let it run a few minutes
without load to cool. At your earliest convenience
after stopping the unit, check the engine oil level and
gasoline supply, if used.
If your home standby unit has a remote start-stop
switch in the house, garage, etc., as shown in Figure
15, proceed to instructions given under Remote
Stopping.
If your home standby unit start-stop switch in the
compartment is like that shown in Figure 16, proceed
to instructions given under Stopping the Unit at
Compartment.
Remote Stopping (remote switch in house, garage,
etc.): Depress and hold the remote start-stop switch
to STOP. Release after the generating set stops.
EXERCISING
Infrequent use of units can result in the following:
Water condensing in engine fuel and lubrication sys-
tem causing contamination and/or rust, loss of pro-
tective oil film on moving engine parts, loss of engine
fuel prime due to drain-back and/or evaporation, bat-
tery discharge due to internal and external current
leakage, and breakdown of generator insulation due
to water absorption.
Proper exercising does the following: Elevates en-
gine oil temperature to 180 o F (82.2° C) evaporating
water from engine lubrication system and generator
windings, re-establishes a protective oil film on en-
gine parts, recharges battery to full normal potential,
and brings generator up to normal operating temper-
ature through actual application of load. The engine
oil temperature should be held at 180° F (82.2° C) for
at least 20 minutes and the unit should be exercised at
least once each month.
Proper exercising can usually be accomplished by
observing the following procedures: Perform all speci-
fied maintenance checks, starting unit and applying
load by creating a simulated power fai I ure. This exer-
cises the control and switchgear systems. Applying
not less than 50 percent load to heat up engine and
generator as described above; exercising unit long
enough to provide at least 20 minutes running time at
normal operating temperatures. This will require at
least 60 minutes total running time. Provide approxi-
mately 1 minute of operation at no load to allow the
engine to cool down.
