Electric connection
• Ask a professional electrician to make the power connection to the power supply. Comply with the corresponding
mandatory rules.
• The fixed installation shall incorporate a device to assure the omni-polar disconnection of the energy feed.
• Assure the electric requirements described in this Instructions and in the hydro equipment nameplate match with the
power supply capacity values.
• The hydro pneumatic has one-phase motor protected against overload using a thermal device (over-current) set in the
winding.
Pressure Switch
• The hydro pneumatic machine is equipped with a pressure switch (pressurestat) that turns on the motor when the tank
pressure is equal or lower than the starting pressure.
• The pressurestat turns off the motor when the pressure inside the tank increases up to the stopping pressure.
CAUTION
The pressurestat is programmed in the factory to correct the starting and closing pressure.
Preliminary Increase of the Filling Up Pressure
• If in the long term the equipment starts running after a slightly emptying
water (approximately 0.5 L), the preliminary increase of the filling up
pressure in the tank shall be reestablished:
1. Disconnect the feed.
2. Open the pressure line (open the male or nozzle) let the water flow out
completely.
3. Unscrew and remove the drain cap to empty the tank. The air control
valve is in the rear of the tank in the horizontal tank equipment and in the
upper side in vertical tank equipment.
4. Connect the compressors' airline to the air control valve with a
"pressure valve" and a pressure gauge.
5. Get to the filling up preliminary pressure:
0.12 MPa - 0.14 MPa (18 PSI - 20 PSI).
6. Connect the equipment again and check its functioning.
• To avoid issues, check regularly the pre-loading pressure in the tank. At
this point, disconnect the equipment to the feeding source and open the
feed key to eliminate the pressure from the system. Then, remove the cap
(A) in the rear of the tank and measure the pre - charge pressure in the
valve (B). Measure with an independent pressure gauge.
• Only authorized staff shall open and install the
CAUTION
pressurestat. Disconnect the equipment from the power source before
opening the pressurestat.
Start Up
Purge
• The first time you start the hydro pneumatic equipment or after a
long period of inactivity, or when air entered into de system, fill the
pump with clean water before you start it.
• Remove the purge cap (A) and fill-up with water up to the orifice level.
• Screw the cap and start the hydro pneumatic equipment.
WARNING
Never start the hydro-pneumatic equipment when the
pump is empty. If it happens accidentally, turn off the hydro-pneumatic,
wait until it cools down and then gill the pump using water.
