LP/NG FUEL CONVERSION
The PSS12H2W/A generator systems have been
tested on NATURAL GAS prior to shipment. If you are
going to use them on LP vapor, follow the procedures
outline in fuel installation.
LUBRICATION
Before starting the engine, fill the crankcase with the
proper weight/grade of oil, as recommended by the
engine manufacturer’s maintenance instructions. The
necessity of using the correct oil, and keeping the crank-
case full cannot be over emphasized.
INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check to
be sure the selector switch remains in the “stop” position.
This should be your last step before initial start-up.
A customer supplied twelve-volt battery is required to
complete the installation. Installation of the highest CCA
rated battery, within the correct BCI group, will increase
cold weather starting performance. Gel batteries should
not be used with the battery tender installed in the
generator enclosure.

*****CAUTION*****
EQUIPMENT DAMAGE - Always connect the positive
cable first and the negative cable last, when disconnect-
ing, it is negative cable first and positive last. Failure to
connect and disconnect in the proper sequence can
cause equipment damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the control panel; the
negative (-) battery terminal is connected to the negative
cable (ground) from the engine generator assembly.
All connections must be clean and tight. Check the
electrolyte (fluid) in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.
*****CAUTION*****
EQUIPMENT DAMAGE - NEVER JUMP START these
units. Doing so will destroy the engine control module
rendering the unit non-operational. Remove and fully
recharge the battery before attempting to start.
CONNECTING THE BATTERY CHARGER
A two-stage battery tender is provided on all PSS series
generators. This battery tender charges at a rate of 750
mA until the battery is fully charged and then automati-
cally switches to a 13.2 VDC float charger. The charger
has an indicator light on it, red indicates it is charging,
and green indicates it is in the storage mode (float
charge). This charger is mounted on the engine genera-
tor set in the same location as the other AC and DC
connections.
This battery tender requires a circuit breaker protected
AC circuit from your distribution panel be run out to the
engine generator set. These AC wires can be run in the
same conduit as the other AC leads from the generator.
It is suggested that this circuit be fused for 15 amps.
A 120 volt receptacle is mounted in the generator
connection box. The receptacle is prewired with black,
white and green leads attached to it, this is where you
will connect your 120 volt fused power feed.
** NOTICE **
The battery tender is not intended to recharge a battery
which has become completely discharged. It is de-
signed to produce enough current to recharge a slightly
low battery, maintaining it fully charged.
MOUNTING THE AUTOMATIC
TRANSFER SWITCH (A.T.S.)
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE- Protect the switch from construc-
tion grit and metal chips to prevent a malfunction or
shortened life of the switch. Contactors returned for
warranty consideration wilth foreign material inside of
them will not be warranted.
The Automatic Transfer Switch connects the load
(lights, furnace, outlets, etc.) to the normal power line
during standby. When normal power fails, the A.T.S.
starts the engine generator set, disconnects the power
line and then connects the load to the standby generator
set. When normal power is restored, the automatic
switch retransfers the electrical load to the normal
service and stops the engine. The A.T.S. panel should
be mounted as close to the distribution panel as
possible.
*****NOTE*****
EQUIPMENT DAMAGE- The NON-UL Winco ATS does
not protect against undervoltage. If you are in an area
that is susceptible to brown outs (low voltage) you may
want to consider adding an undervoltage sensor to
standard ATS panel. Contact your dealer or WINCO.
