Start-up

If the unit has been supplied integrated with a air filter, lubricator and regulator then please refer to the
manufacturers instructions as supplied, in conjunction with the recommendations in the air motor
operating manual.
Please refer to the pumphead instructions to ensure correct loading and operation of the pumphead.
Prior to start-up ensure that the tubing material used is listed in the "Special conditions of use for safe
operation - Tube materials suitable for use with this equipment" section of the pumphead manual.
The unit will self prime, minimise the time to prime the pump as dry running will reduce the life of the
tube.

Check list for installation in explosive environments

Complete the following check list prior to starting installation in an explosive environment. All actions
must be completed in accordance with Directive 2014/34/EU.
Check ATEX pump and motor labelling and configuration. Ensure that they conform to actual
l
installation (see section 13 "ATEX marking" on page 19).
Check the ambient temperature of the site and the ability to maintain proper ambient temperature.
l
(see section 7 "Pump specification" on page 12).
Check the site to make sure that the motor will be adequately ventilated and that there is no external
l
heat input (e.g. couplings). The cooling air may not exceed 104ºF/40ºC.
Check that the pump is not damaged.
l
Check the installation has been carried out correctly in accordance with pumphead, gearbox and
l
motor manufacturers instructions.

Troubleshooting

Should the pump fail to operate, make the following checks to determine whether or not servicing is
required.
Refer to the motor manufacturer's manual to ensure correct connection of the electrical or air
l
supply.
Check that the pump is not stalled by incorrect fitting of tubing.
l
Any deviation from normal operating conditions (increased power
consumption, temperature, vibrations, noise) or warning signals by
monitoring equipment suggest malfunction. Inform the responsible
maintenance personnel at once to prevent the trouble from worsening.
If in doubt disconnect the pump immediately.
