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 layout).
The pressure gauge should be on the discharge of the pump or in the discharge header
(depending on pump size and duplex package configuration layout).
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.
