As a guide the options below will allow you to quickly set the Hydrascan cut-in pressure.
NOTE: Check to ensure the pump is full of water and that all
air has been purged from the system.
1. If pump will not start and red light is on, turn adjusting screw slowly counterclockwise until light goes
out.
2. If pump will not start and red light is off but starts when yellow button is depressed, open a faucet and
leave running, turn adjusting screw slowly clockwise until pump starts.
Chart below is an approximate guide to cut-in pressure settings (NOTE: pump stops on flow not pressure,
you cannot adjust the cut-out pressure).
Should you need to more extensively trouble shoot your installation we suggest you use the method below.
Equipment required: Hydrascan
Gauge, 1"BSP Tee, 1"BSP Nipple, tap with garden hose quick
connector.
Flat blade screwdriver.
Pressure gauge installed in pipework near pump and outlet
nearby.
Fit Hydrascan CL test kit to top of Hydrascan

pump. If a tap is not near the pump you may require someone else to open and close
the nearest tap on command.
Step 1 Fill the pump with water.
Step 2 Start pump and open tap to purge air out of pipework.
Step 3 Close tap and pump will turn off.
Step 4 Remove cut-in screw cover and gently turn the adjusting screw
anti-clockwise until it comes to a stop.
NB If the pump starts during step 4, simply wait a few seconds
until the pump stops then repeat step 4.
Step 5 Slowly open the tap and allow the pressure gauge to drop to the
desired cut-in pressure. Close the tap to hold the system at this
pressure.
Step 6 Slowly turn the adjusting screw clockwise until the pump starts. The pump will start for a few
seconds and then stop. The low pressure indicator light will be illuminated momentarily when the
pump first starts. If the pump stops and the light does not go off adjust to a lower cut-in pressure
(turn screw anti-clockwise) or consult the trouble shooting guide.
Step 7 Replace the cut-in screw cover. Congratulations: Your pump is ready to use.
Always disconnect and lockout all electrical power when installing or working on pumps,
motor or switches. Insure the power supply breaker is off or the disconnect (where used)
is off.
