3. Check Valve
If the discharge hose has a vertical lift of more than 10
metres, we recommend that a check valve (not supplied)
is installed in the hose near the pump. This will prevent
potentially destructive water hammer occurring when the
pump is shut down.
OPERATION
1. Siting the Equipment
Note:
The Evo-System Engine with the pump attached
should be sited with reference to the instructions given
in the Evolution Engine Instruction Manual (SAFETY
INSTRUCTIONS FOR EVO-SYSTEM ENGINE).
Site the equipment and check:
• The equipment is as level as possible.
• The wheel brake is applied.
• The surface is firm and stable.
• No combustible materials are close by.
• The area is well ventilated, and that there is no danger
from the expelled exhaust gases.
Note:
The Evo-System Engine is fitted with a low oil level
shut down feature which protects the engine from damage
due to lack of lubrication. This feature could be activated if
the machine is sited on a slope of greater than 10
0
.
2. Initial Priming of the Pump
Note:
The pump is self-priming only when the pump body is
filled with water.
• Remove the filler plug from the top of the pump.
(Fig. 4)
• Fill the pump fully with water. Do not leave any air gap.
• Replace the filler plug. Refilling is only necessary if the
pump has been drained or the water supply has been lost.
Note:
All water pumps can be ‘temperamental’ when
priming. Initial priming can sometimes be assisted by
temporarily restricting the output flow (the operator could
place a foot on the outlet hose) until priming is achieved.
Never allow the pump to run ‘dry’ for any prolonged period.
