Product description and type designation

• The WASEX washer pump is an important element for effective video surveillance in hazardous areas because it guarantees sharp images in all environmental conditions and reduces the need for maintenance.
• The WASEX system is designed for the MAXIMUS series and is also compatible with third party products.
• The kit is composed of a 10 liter stainless steel tank with an explosion-proof certified solenoid valve and some versions of the product also have an explosion proof certified pressure switch.
• The WASEX version with pressure switch has a clean contact that switches when the tank pressure goes under a preset value.
• The pressure switch can be connected to the alarm of the MAXIMUS series cameras or it can be connected directly to the alarm of the main electric box, to warn operators to reset the pressure and level of the water.

Filling the tank

The operation of the pressure switch and the frequency of air filling depend on the amount of water in the tank. Testing is recommended to determine the amount of water in the tank appropriate for the specific application.

With the handle 01 of the pump locked in the safe position, unscrew the pump from the container. Fill the tank (02) (10l max) Screw in the pump in the tank.

Pressurize the tank using the manual pump

Release the handle of the pump by pressing it downwards and turning clockwise. Pressurize the tank pumping with the handle of the pump until the desired pressure is reached

• 4bar with 20m water delivery antistatic pipe (supplied)
• 6bar with 30m water delivery antistatic pipe (available as an accessory)

If the maximum pressure (6bar) is exceeded, the safety valve activates to discharge the excess pressure. Lock the knob of the pump in the safe position, pressing it downwards and turning anti clockwise.

Pressurise the tank using the compressed air valve

Pressurising the tank using compressed air is only permitted outside the classified zone. Connect the compressed air pipe on the compressed air filling valve (01). Once the desired pressure is generated, remove the compressed air pipe.

Product closure
