5.2
What to do before starting up the pump for the first time
You should complete a range of checks and controls before starting up the pump, in order to prevent errors or accidents during the
initial commissioning stage:
Check no damage was caused to the machine during assembly, installation or transport (stability, screws/bolts secured
correctly, correct coupling of mechanical parts/gears);
Stop all use of the pump immediately if you see any leakage from pressurised pipes and eliminate the cause of the
Leakage
Before starting up the pump, make sure the oil is up to the correct level. We recommend doing the first oil change within
the first 50 hours of operation. Subsequent oil changes should take place every 500 hours or more often in case of heavy
use. The type of oil used for our pumps is SAE 10/40W.
Replace the oil cap fitted during shipment with the bleed cap supplied.
Always
follow the safety instructions listed in
section 3.
Failure to comply with these operating conditions invalidates the warranty.
The machine should NOT BE OPERATED until any damaged parts have been repaired or replaced if it does
not seem to guarantee it will run safely and properly.
After the installer has completed all of the required connections, he will test the product to ensure all the devices it contains work
properly:
After starting up the pump, aid priming by keeping the delivery line open (lance). Do not let the pump run dry: this can result
in rapid seal wear and invalidates the warranty.
After use, run the pump with clean water for several minutes. Do not use the pump at low temperatures. To prevent
freezing, run the pump dry for about 20 seconds to drain the pipes.
5.3
Long periods of downtime
Prepare the pump if it will not be operated for an extensive period of time:
Run the pump with clean water for several minutes
Run the pump without water for 10 seconds with the delivery line (lance) open to drain the pump and the delivery circuit,
thus preventing the formation of deposits
Wash the pump with water and solvents authorised by current legislation
Dry the pump using compressed air
Lubricate any unpainted parts
Avoid the possibility of the system coming into contact with corrosive substances.
Mineral oils will degrade in case of downtime or inactivity for more than six months, and so must be
replaced.
When resuming operation of the machine after an extensive period of inactivity, repeat the initial
commissioning controls (subsection 5.2). Also check the oil and that all screws are secured tightly.
5.4
Operating the pump
To safeguard proper pump operation, the pump should preferably be fed (maximum pressure 8 bar), otherwise it should be located
under the water head or at the same level as the tank.
Hawk pumps are delivered with their first oil fill and are fitted with a sealed cap to prevent oil spilling during transport. Before starting
to use the pump for the first time, remember to replace the sealed cap with the cap with the dipstick and bleed.
