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.

Where local regulations require a sump to be fitted:

a. Sumps must be provided at all dispenser installations with secondary containment pipework

and at all new installations; and

b. at all sites with sumps, dispensers should be installed with a liquid level detection device

fitted in the sump that will raise an alarm if liquid is detected in the base of the sump.

The pump inlet must not be pressurised at any time. This will cause fuel to flow

from the air eliminator. Unregulated connection to an above ground tank will cause

pressurisation.

For above ground tanks a regulator valve such as a Tokheim valve or similar

device MUST be used so that the inlet of the pump cannot become pressurised at any time.

The air switch is not to be disconnected. Disconnection will void NSC and TMU

approvals.
