HYDROMATIC RHMPC15 and HYDROMATIC RESTART RPC15ADS-IT  
ITALIAN PRESSURE CONTROLLERS PATENTED DESIGN 

 

OPERATION 

The Hydromatic electronic control senses when there is pressure reduction (due to a  discharge tap being opened) and  starts the pump  and 
keeps the pump on while there is demand, to continuously provide pressure and flow, assuring constant flow and the correct on/off control 
of  the  pump.  Hydromatic makes  the  pump  stay  on  for  all  duration  of  the  use  (if  the  flow  is  over  1.5  L/min),  and  stops  the  pump  about  15 
seconds from the closing of the tap. 
 

WARNING 

The device can be used only with clean water.

INSTALLATION 

Before proceeding with the installation and the starting of the Hydromatic, it is essential to prime the pump correctly. The controller should be 
installed always in a vertical position (refer fig. 1 and 2). Avoid installing non-return valves closer than one metre from the Hydromatic, and do 
not install taps between the pump and the Hydromatic.  
 
The following installation instructions are mandatory: 

Flexible hose with a barrel-union for connection, to protect the unit from possible damage due to movement and vibrations. 

Ball valves must be fitted on the suction and the discharge. 

A Y-Strainer or Prefilter must be fitted in the suction between the tank and the pump 

HYDROMATIC CONTROLLER FUNCTION AND OPERATION:  

The Hydromatic  pump controller is designed to be almost completely automatic, and will restart itself if the pump runs out of water; you 
should not normally need to do anything.  Instructions and basic function; 
a) 

Use for CLEAN rainwater only – you must fit a prefilter or Y-Strainer to the intake (suction pipe) of the pump 

b) 

Do not use a low quality generator for power supply as this may damage the electronics 

c) 

Protect from direct sunlight to avoid UV damage to the plastic 

d) 

The pump controller will stop the pump if there is no water in the pump, for the RHMPC15 model it then stays off until the reset 
button is pushed, or the power is turned off & on again. 

e) 

HYDROMATIC RESTART ONLY:

 It rechecks for water several times over the period of about 20 minutes – it makes the pump start 

each time, to try and “re-prime” itself (fill it back up with water) It might “crackle & gurgle” due to air in it, as it tries to restart.  

f) 

HYDROMATIC RESTART ONLY:

 If there is insufficient water to operate normally, the controller then switches off for 24 hours and 

tries again, and continue to do that every 24 hours until there is sufficient water and the pump can operate normally.   

g) 

If the restart happens in the middle of the night it can be annoying!  In the morning, turn the power off & on again after 30 seconds 
and it will reset itself so it does the checking in daylight hours.  

i) 

You can reset the function back to the beginning anytime by pressing the reset button 

j) 

If it is many days before it rains again, turn off the power to the pump, at the power outlet 

k) 

Occasionally when the pump re-starts after a run-dry event, some air might come through the pipes, this is normal it is not a fault.
