Static Electricity Precautions

Electronic components used are sensitive to static. Please take anti-static precautions.

An anti-static wrist strap should be worn and connected correctly when working on any

electronic equipment. If an anti-static wrist strap is unavailable, or in an emergency, hold onto

an earthed part of the pump/dispenser frame whilst working on the equipment. This is not a

recommended alternative to wearing an anti-static wrist strap.

Note: Compac Industries Limited reserves the right to refuse to accept any circuit boards

returned, if proper anti-static precautions have not been taken.

Once the pump is received on site, check that no damage has occurred while in transit – in

particular, damage to electronics due to vibration or jarring. All terminals and plugs should be

checked, including IC chips, to ensure they are securely in place.

Installation should be in accordance with local regulations.

To obtain maximum flow on a self contained pump, observe the following guidelines:

1. Pumps must not be subject to any head pressure. Design your installation to eliminate any

possibility of this occurring.

2. Total length of horizontal piping between tank and pump should be no longer than 18

metres. Use galvanised steel or approved non-metallic pipe and fittings.

3. For 40 l/min pumps, use 1½" pipe. For 80 l/min pumps use 2" pipe.

Note: Ensure you remove bung from the pump inlet before connecting the pipe.

4. Pipe must slope up from the tank to the pump (approximately 15 mm per metre). Pipe

should be straight and supported along its length.

5. All horizontal piping must be buried at least 450mm below ground level.

6. The area under the pumping unit(s) must be filled with sand or dirt as far up the suction line

as possible. Use water to pack the sand or dirt when put in place.

7. Avoid asphalt drive surfaces covering the piping. Asphalt increases heat absorption causing

vapour lock.

8. Static lift must not exceed 3 metres (vertical distance from the product level in the tank to

the centre of the pump unit).

9. To absorb ground movement from settling of the tank, frost heaving of the ground or pump

island settling, a swing joint must be used in the supply line at the tank and directly

underneath the dispenser. Three additional directional changes using elbows are permitted.

10. Piping must hold a 3.4 Bar (50PSI) pressure test for a minimum of 10 minutes.

11. It is recommended that a vertical, in-line check valve be installed underneath the pump.

12. The dispensing equipment shall be installed to prevent the delivery hose from contacting the

ground when not in use.

13. A Check Valve must be installed at the tank end of the suction pipe on the top of the tank in

a serviceable location. Many clients install an extra check valve at the inlet to the pump. It

is important neither of the check valves interfere with the flow of fuel. They must be

adequately sized

Refer to the footprint drawings for pump installation details.
