7. If the pressure is correct, remove the meter and
reinstall the pipe plug.
8. You are now ready to make the final fuel mixture
adjustment. Refer to adjustment section in this manual.
PROPANE TO NATURAL GAS
1. Turn off fuel supply.
2. Remove the fuel line from the carburetor at the
demand regulator.
3. Invert the regulator so the column is in the upright
position. Remove the cap on the upright column of the
regulator. This will expose the pressure spring
adjusting screw. Turn the screw all the way out (CCW)
and then back in (CW) about 8 turns. The plug should
be approximately half way down for initial starting.
4. Reconnect the fuel line at the regulator.
5. Remove the 1/8 NPT plug (the one closest to fuel
solenoid) located on what is now the bottom of the
regulator. Connect a fuel pressure meter or a manom-
eter where the plug has been removed. Move the
generator control switch to the run position. As the unit
starts to crank the fuel solenoid will open and you
should get a pressure reading of between 4 to 6
ounces (7 to 11 inches of water column).
6. If the pressure is correct, remove the meter and
reinstall the pipe plug. Next remove the 1/8 inch NPT
plug on the carburetor side of the regulator and install
the pressure meter. Move the generator switch to the
run position. As soon as the solenoid opens the
pressure should rise 2.5 to 3 oz. just as the engine
starts to crank. If it is within this range replace the cap
on the column. If not, adjust the screw down to
increase and up to decrease and retest.
7. You are now ready to make the final fuel mixture
adjustment. Refer to adjustment section in this manual.
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
crankcase 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.
PSS8000 - A customer supplied twelve-volt BCI group U1
battery rated 235 CCA (minimum) is required to
complete the installation. Install the highest CCA rated
battery available for best cold weather starting
performance.
PSS12000 - A customer supplied twelve-volt BCI group
26/70 battery rated 450 CCA (minimum) is required to
complete the installation. Install the highest CCA rated
battery available for best cold weather starting
performance.
PSS20000 - A customer supplied twelve-volt BCI group
24 battery rated 500 CCA (minimum) is required to
complete the installation. Install the highest CCA rated
battery available for best cold weather starting
performance.
*****CAUTION*****
EQUIPMENT DAMAGE - Always connect the positive
cable first and the negative cable last, when discon-
necting 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.
A self tapering trickle charger, producing up to 40 Ma is
built into the Automatic Transfer Switch panel to keep
the battery in top condition during standby periods. A
small green light on the Transfer Switch cover is
illuminated to indicate the proper operation of the
charger. Since the charger has an automatic charge
regulation circuit, the charger has no control knob and
requires no adjustment.
** NOTICE **
The trickle charger is not intended to recharge a battery
which has become completely discharged. It is
designed to produce just enough current to maintain a
fully charged battery .
