Pressure Switch; Start Up - Truper HIDR-1/2X24 Manual De Instrucciones

• 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 calibrated 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 0.13 gal), 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:
0.19 MPa - 0.20 MPa (28 PSI - 30 PSI).
6. Connect the equipment again and check its functioning.
Purge
• The first time you start the hydro pneumatic equipment,
or after a long period of inactivity, or when air enters into
the system, fill the pump with clean water before starting
up.
• Remove the purge cap (C) and fill with water up to the
orifice level.
• Screw the cap and start the hydro pneumatic equipment.
Never start up the hydro pneumatic
WARNING
equipment when the pump is empty. If occurs accidentally,
turn off the hydro pneumatic equipment immediately. Let
it cool down and then, fill the pump with clean water.

Pressure Switch

• 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.
CAUTION
• Only authorized staff shall open and
install the pressurestat. Disconnect the equipment from
the power source before opening the pressurestat.
