Viking Duplex Fuel Oil Package
Field Start-Up Guide
Before arriving on job site, make sure you have:
A copy of the approved drawing or certified print of the Duplex Fuel Oil Pump Package
A copy of the approved drawing of the Control Panel.
Read all of the instructions, notes, and suggestions in this bulletin to become familiar with the
start-up procedures. If you have any questions or require clarification please contact our
systems specialist, Humberto Da Silva, P.Eng. at (905) 542-8906 ext. 204 (or North America
toll free at 1-888-845-7867 ext. 0 and asked to be transferred)
When you arrive at the site confirm the following:
Check the name plate rating on the Control Panel and compare with the incoming voltage
and motor ratings.
The compound gauge should be located on the pump suction or in the suction header
(depending on pump size and duplex package configuration layo ut).
The pressure gauge should be on the discharge of the pump or in the discharge header
(depending on pump size and duplex package configuration layo ut).
Examine the suction header and confirm that the arrow cast into suction strainer points
toward the pump suction.
Confirm the sales order number stamped on the serial number plate matches the packing
slip. The serial number plate is typically located on the base plate of the unit.
On the control panel confirm the voltage, phase, horsepower, certifications and part number
stamped on the serial number plate located on the door of the panel match the specifications.
Do not open the panel door.
Observations to be made on site:
General Installation
The package should be anchor to the ground to prevent movement. If the unit is mounted on
a shelf it should be properly bolted.
All piping (suction, discharge and relief return lines) should be externally supported to prevent
pipe stresses being transferred to the unit. Ideally flexible connections should be used.
Suction Piping
If possible follow the suction pipe to the supply tank. The suction line should go around
obstacles instead of over them. This is to prevent air lock (the system will not prime if the
suction line is air locked).
If there are any valves on the suction line they should be in the open position.
With long suction pipe there should be a hand operated pump to evacuate the air from the
suction line. This pump should be piped parallel to the duplex package.
The relief valves piping can not be piped back into the suction piping. Both valves can be
piped to a common pipe. But that pipe has to be piped back to the supply tank. There should
not be any other valves in this line. If there is any they should be always in the open position.
Discharge Piping
The discharge will be piped into a day tank or directly into the diesel generator or boiler
depending on the installation.
If possible follow the discharge pipe. If there are any valves on the discharge line they should
be in the open position.
Take a look at the day tank. There should be the line from the duplex pump unit, overflow and
floats.

Priming the Duplex Fuel Oil Package:
1. On the Control Panel make sure both the Main Disconnect “ON-OFF” switches are in the
“OFF” position (power off).
2. Take a look at the suction gauge to see if there is any pressure on the suction line. If there
is pressure and the application is not a flooded suction the suction line is pressurized.
Carefully remove the drain plug from the basket strainer to release the compressed air.
3. Turn the four ball valves connected to the pressure gauges (suction & discharge gauges)
to closed position.
4. Remove the thumbscrew from top of the lid of the basket strainers, rotate the lid counter
clockwise until the pin hits and stops, and then remove lid.
5. Open the suction valves.
6. Fill the strainers with diesel (the suction valves should be in open position, as you fill one
strainer the liquid level will flow in the other strainer).
7. Reinstall the lid with the tab of the lid just to the left of the boss with the body, rotate the lid
clockwise until the holes line up, and reinsert the thumbscrew.
8. Both the suction and discharge ball valves should be in open position.

9. On the Control Panel, turn the “Hand-Off-Auto” selector switches to “Off” position for both
P1 and P2.
10. Turn both the Main Disconnect “On-Off” switches to “ON” position (power on).
11. Turn the “P1-Auto-P2” switch to “P1” position.
12. Have some one observe the motor fan for the next operation.
13. For P1 turn “Hand-Off-Auto” selector switch to “Hand” position and P1 will start.
14. After approximate 3 seconds turn the “Hand-Off-Auto” selector switch for P1 back to “Off”
position.
15. Confirm that the motor fan had spun in the proper rotation. If the motors are not rotating
properly have an electrician switch the motor leads and check again the rotation of the
motors.
16. Repeat steps 11 to 15 for P2.
17. Turn the four ball valves connected to the pressure gauges (suction & discharge gauges)
to the open position.
18. For P1 turn “Hand-Off-Auto” selector switch to “Hand” position and P1 will start.
19. Observe the suction compound gauge; it should start pulling a vacuum. The discharge
gauge will read 0 psi. Run P1 for no more than 2 minutes then turn it off. Place you hand
on the pump (around the seal area) and if it starts heating up, turn off the pump to prevent
mechanical seal failure.
20. When the pumps are primed and pumping the discharge gauge will show a positive
pressure.
NOTE: If the suction line is long you may have to refill the basket strainer again. Before this is done the
suction valves will have to be in the closed position, other wise the vacuum will be lost. Then alternate
running P1 and P2 in manual mode.
NOTE: Some local codes specify a anti-siphon valve to be installed on the suction line. It is usually
installed close to the main supply tank. In some cases this valve will prevent the pumps from priming. If
the pumps don’t prime after a few attempts ask the contractor to loosen the spring in the anti-siphon valve
and then after the pumps are primed the spring can be set in order to meet local cod es.
NOTE: If the installation has a flooded suction, turn the suction and discharge valves to the open
position. The suction pressure gauge should show a positive pressure. If it doesn’t follow the suction line
to the supply tank and see if all the valves are open. If all the valves are open and the pressure gauges
don’t read a positive pressure there a blockage in the line. The blockage will have to be cleaned before
running the pumps.

CONTROL PANEL
Check the name plate rating of the Control Panel and compare with the incoming line voltage and
the motors ratings.
Adjust overload relay setting to full current rating
Check that motor protector push actuator(s) is (are) in start position.
Check that float switches are adjusted to the desired levels
Check that the controller is properly connected to the pump motors
If motors are rotating in the proper direction (as checked in steps 10 to 16 under Priming section),
and all the above checks out correctly, turn the “Hand-Off-Auto” switches for both P1 and P2 to
the “Auto” position.
Activate float switches manually and test if the pumps start and stop at desired levels.
Once the level falls below the start lead pump level float switch FL2 (as shown in diagram under
Float Controls), the pump motor is energized and the lead pump starts pumping fuel into the tank.
If the lead pump has failed and the level falls below FL2 start lead pump level float switch, the
“Lead Pump Failure” red pilot light is turned on and the lag pump motor is energized so that the
lag pump keeps pumping fuel into the fuel tank.
In order to turn off the “Lead Pump Failure” red pilot light, the manual “Reset” red pushbutton
must be pressed.
Once the level reaches the stop all pumps level float switch FL3, the pump motors are de-
energized and the pumps stop.
If the alternation selector switch “P1-Auto-P2” is in the “Auto” position, the stop all pumps float
switch FL3 triggers the alternator and reverses the order of the lead and lag pumps. For
example, if P1 was the lead pump before the trigger, P2 will become the lead pump after the
trigger.
RELIEF VALVES
Checking Relief Valves Current Setting
1. With the pump running notice the reading on the discharge pressure gauge.
2. Slowly close the discharge ball valve.
3. Operate only one pump at a time in manual mode.
4. The reading on the discharge pressure gauge will increase.
5. Make a note of the pre ssure reading when the valve is fully closed; this value is the pressure
relief valve setting. It should be approximate 15 to 20 psi greater than the specified pump
discharge pressure.
6. Open the discharge valve and turn the pump off.
7. If the pressure relief setting in satisfa cto ry, repeat for the other pump.

Setting the Pressure Relief Valves
1. Turn the “Hand-Off-Auto” switches to “OFF” for both P1 and P2.
2. Remove the cap (item J) of the
pressure relief valve for pump P1.
3. Loosen the lock nut (item F)
4. Turn the adjusting screw (item C)
clockwise to increase the pressure
setting or counterclockwise to
decrease the pressure setting
5. Tighten the lock n ut (item J)
6. Reinstall the cap (item B) onto the
valve.
7. Turn the “Hand-Off-Auto” switch for
P1 to “HAND” position.
8. Slowly close the discharge ball valve
for P1. If the pressure relief setting is
not satisfactory repeat the operation t
o
adjust the adjusting screw.
9. Repeat step s 1 to 8 for pump P2.
FLOAT CONTROLS
The standard duplex control panel contains NC relays to operate three f
switches (switches supplied by others) for the day tank. If more than three
floats are required, the control panel would have to be ordered with
optional NC relays.
The top float (FL3) stops both pumps, the middle float (FL2) starts the lead
pump and the bottom float (FL1) starts the lag pump.
It may not be practical to fill the day tank to test the operation of the panel. A simpler way is to have the
electrician simulate the open and closing contacts of the floats to check the operation sequence. Thi s
procedure can be used to check the high and low level alarms (if supplied) in the panel. The electrician
can check the conductivity of the float (normally open or normally closed) to see if they are the same as
specified. In some cases there is no day tank and the pump duplex unit pumps directly into the diesel
generator or boiler. The panel will receive the signal from the generator and start the lead pump.

PRESSURE SWITCHES
If the duplex unit is supplied with pressure switches (either single or dual stage) they will be installed on
the discharge line. The pressure setting will be factory set, but they are field adjustable.
To simulate a low pressure condition on the discharge line, have the control panel on automatic mode
and then close the discharge valve of the pump running. The relief valve will open and the pumping liquid
will return to the supply tank. The pump will shut down and a red light will come on the panel, the time will
be that is set on the timer.
It is difficult to simulate an actual high pressure shut down. Have the electrician simulate by open or
closing the contacts in the control panel.
Field adjustment of the pressure setting can be done by the following:
Single Stage Pressure Switch – Square D – 9012-GNG2
See UDF400-1 Single Stage Pressure Switch.pdf
Dual Stage Pressure Switch – ASCO – SC10D-TG10A21
See UDF400-2 Dual Stage Pressure Switch.pdf
FLOW SWITCHES
If the duplex unit is supplied with a flow switch it will be installed on the discharge line. To simulate a low
flow condition on the discharge line, have the control panel on automatic mode and then close the
discharge valve of the pump running (either P1 or P2). The relief valve will open and the pumping liquid
will return to the supply tank. Within a few minutes (usually 1 to 3 minutes) based on the time set on the
timer, the control panel will start the other pump and the “Low Flow” Signal red lights (optional equipment
required for installation of low flow switch) will light up on the panel.
