IMPORTANT WARNING NOTES
1. On above ground storage tanks an angle check valve fitted
with the appropriate spring or pressure regulating valve must
be fitted at the tank outlet to prevent loss of fuel under gravity
in the event of vandalism or accidental damage.
2. This pump must only be used to dispense diesel or other
liquids classed as category 1, 2 or 3 in accordance with
European Regulation No. 1272/2008.
3. Installation of this equipment and its associated tank, pipe
work and fittings should only be carried out by qualified fuel
installation engineers.

4. The installation must be carried out in accordance with the
requirements of EN 60079-14 the latest relevant electrical and
local authority regulations and standards.
5. It must not be used with other liquids or for other applications.
We will accept no warranty claims or liability if it is used for
other liquids or applications.

INSTALLATION INSTRUCTIONS
1. Check you have the following items:
1 off Alpha pump
1 off delivery hose
1 off front door key
2. Open the front panels using the key provided.
3. Remove the rear panels, if necessary, and store safely.
MOUNTING
4. Bolt the pump to a raised firm level foundation, at least
150mm in height, by means of the four 14 mm diametermounting holes provided. Locate the drip tray between the
pump base and the foundation with the lips around the holes
facing upwards.
NB: When the drip tray is fitted to the pump it must be sealed
to its foundation, with a suitable elastomeric substance, to
prevent leaked fuel "wicking" back underneath the pump. To
maintain the environmental integrity of the drip tray any
possible leak path through the pump mounting holes or the
cable and pipe entry holes must also be sealed.

PIPEWORK
5. Connect the 11/2” diameter pipe from the tank to the suction
inlet flexible connector of the pump. The inlet thread of the
flexible connector flange is 11/2” BSP taper female. Seal the
joints with a suitable thread sealing compound. The pipe work
must be sealed to the drip tray (if fitted) to ensure no leaking
fuel can flow underground. An alternative pipe work entry
point, for above ground pipe work, is provided at the rear of
the pump base. Push out the plastic cover plate if required.
NB:On above ground tanks an angle check valve fitted
with the appropriate spring or an anti-syphon valve must
be fitted in the suction line to prevent spillage or leakage
in the event of damage.
6. Connect the delivery hose and selected ATEX approved
nozzle to the pump outlet in accordance with the instructions
supplied with the individual components. Ensure the nylon
hose-sealing washers are in place on the hose end. It should
be hand tight plus a quarter turn.

ELECTRICAL
7. Remove the covers from the junction box.
8. Connect a constant 220/240V AC 50 Hz supply, fused at 16
amps, to the terminal block in the junction box as shown on
the wiring details diagram.
NB:The Alpha pump must have a continual 220/240V AC
supply, even when not in use
9. If the Alpha is to be operated in conjunction with a key/card
system, remove the link in the junction box (shown on the
Alpha Installation Wiring Diagram) and connect so that the
control system makes and breaks the connection.
Make connection - Pump on
Break connection - Pump off
Alternatively remove the link and connect a switched live
supply (230V AC 16A max.) to terminal 4 (shown on the Alpha
Installation Wiring Diagram)
Live supply switched on - Pump on
Live supply switched off - Pump off
10. A pulse output for connection to key/card systems is available
from the separate terminals located in the junction box. This is
a passive contact giving 10 or 100 pulses per litre. Contact
ratings are as follows:
Maximum current - 0.25 amps
Maximum voltage - 50 volts
Maximum power - 5 VA
11. Ensure all the terminal screws are tight and replace the
junction box covers.

INSTRUCTIONS FOR USE
1. Remove the nozzle from the holster.
2. Place the nozzle spout in the fuel tank.
3. Squeeze the nozzle trigger to dispense fuel.
On completion of the delivery release the trigger and replace
the nozzle in the holster.

MAINTENANCE
The Alpha should require minimum maintenance in normal regular
use, but as with all mechanical apparatus regular servicing will
prolong its life and ensure maximum efficiency & reliability.
The following should be carried out every 12 months or 1 million
litres which ever comes first.
-
Isolate power supply
-
Inspect & clean or replace pump filter
-
Inspect & clean or replace nozzle filter
-
Inspect & replace if necessary the V-belt
-
Check motor pulley grub screw is tight
-
Re-calibrate electronic display

ERRORS
If an error occurs ERROR, followed by a brief description is shown on the
lower display. The errors are classified as follows:
FLOW TOO FAST The pulser has run too fast (in excess of 300 pulses
per second)
UNAUTH FLOW The meter has turned without the nozzle being
removed
CALIBRATE FAIL A time delay of 2 minutes or more has occurred
during the 20 litre calibration.
PULSER SIGNAL One of the pulse transmitter’s pulse trains has been
interrupted.
PULSE REVERSE The meter has run backwards during a delivery
PULSER POWER The pulser has been disconnected
The error condition is maintained until the nozzle is returned to its holster,
for at least 2 seconds, and then removed again to restart the fuelling
sequence.
TIMEOUT
If, during a delivery, no fuel is dispensed for 2 minutes the display will
show TIMEOUT alternating with REPLACE NOZZLE and the pump will
stop running until the nozzle is returned to its holster, for at least 2
seconds, and then removed again to restart the fuelling sequence.
