3. Ensure all valves
in suction line are
open and switch on.
4. Prime should establish
almost immediately
and a strong flow
of water should be
evident from the outlet.
Allow water to flow for
10-20 seconds to expel
air then close outlet.
5. Automatic Pressure Pumps will shut
down automatically within several
seconds. Manual systems must be
switched off at the power point.
6. If no flow is evident from tap, switch
off at power point and repeat from
step 1 ensuring there is an adequate
supply of water available to the
pump.
Never operate your Davey Dynajet
®
pump for more than a few
seconds without discharge flow.
Maintenance
The only regular attention your new pressure system requires is to check the
pressure tank’s air charge every 6 months. This can be checked at the air valve
with a tyre gauge. Do not charge tank to a higher pressure than 168kPa for E1P
(XP50P) or 196kPa for E2P & E3P (XJ70P & XJ90P).
To check air pressure in tank:
1. Switch off pump.
2. Open outlet nearest to pump to release
water pressure.
3. Remove air valve cap from top of
Supercell tank and charge tank to
168kPa for E1P (XP50P) or 196kPa
for E2P & E3P (XJ70P & XJ90P) using
air pump and check with tyre gauge.
4. Switch on.
5. Close outlet.
