Faults, Possible Causes And Repairs - Rothenberger RP PRO III Instructions D'utilisation

!
Please note: This appliance is for testing only, NOT for filling a system. Using your
RP PRO III to fill a system will damage or break the appliance! If system is empty,
use another method to fill before pressure testing with your RP PRO III
Switch on appliance (Fig G On appliance) and allow to run until satisfied that the system is free of
air via bleed point. Then switch off pump and close bleed point immediately!
6. To achieve the desired test pressure:
Turn on the pump (Making sure control valve V2 is fully OPEN)
•
• Slowly turn control valve V1 clockwise to +BAR, increasing pressure till desired pressure
is achieved. Use V1 to increase and decrease pressure as required!
• Turn control valve V2 clockwise to CLOSE, then turn off pump IMMEDIATELY!
7. If reading on gauge has exceeded desired pressure. Keeping the pump OFF:
• Carefully open V2 and turn V1 toward –BAR till you reach the desired pressure
• Then close V2
8. When testing is complete:
Turn control valve V2 Anticlockwise fully to OPEN
Turn control valve V1 Anticlockwise fully to –BAR
N.B. When storing appliance between uses and for long periods of time, open V1 & V2
fully then turn knobs back clockwise half a turn to prevent valves from sticking!

reaching the terminal box
The electrical current
reaching the terminal box, but
the voltage is very low
Pump seized with ice. Motor
rotor seized up
The pump is working but the pressure isn't rising
Insufficient water supply
Considerable amount of air in
the input water
Water filter is dirty
The pump's gaskets are in bad
condition or the pump valves
have seized up
V1 valve set to minimum pressure Open the V1 valve until the desired pressure is attained.
Discharge pressure irregular and making considerable noise
Air in the supply water
Insufficient water supply
The piping reaches the test pressure but doesn't maintain the desired pressure
V2 valve isn't working
correctly
Check the plug / socket connection. Check the length of the cords leading
to the terminal box. Reassemble the motor's thermal protection or replace
blown fuses. Return to Service Centre.
is
Connect the motor to a supply of 230V, 50 Hz.
For 110V, please use 3KVA transformer.
Return to an official Service Centre.
Check the supply hose: the inner diameter should not be less than 15 mm.
Also, the water pressure at the outlet tap should not be less than 1 bar.
MAIN
Check fittings are tight and water supply is MIN 1bar with sufficient flow.
TANK
Check water tank is full and hose correctly submerged to draw water to pump.
Clean the filter.
Replace the sealing kit R6.1186.
Check the seal at both ends of the supply hose.
Check the supply hose: the inner diameter should not be less than 15 mm.
