Construction Details:

Body, non-return valve, rear part and knob are molded in 30% fibreglass reinforced polyamide 6 (PA6GF30).
This allows for obtaining a high resistance to wear and pressure.

The diaphragm is molded in EPDM ( Ethylene Propylene Diene Monomer ).
This guarantees exceptional reliability and durability.

The flow valve is in stainless steel (AISI 304).
The dimensional stability of the metal guarantees the operation of the components .

The spring is made in UNI 3823 steel wire.
The stabilization process guarantees the operation of the pressure switch, essential for the pump start-up precision and the system pressure adjustment. The dimensions and structure of the same allow for considerably reducing the effects of water hammering.

The box containing the electrical part is moulded in shockproof self-extinguishing PBT.

The use of prime materials and top-of-the-range components allows for achieving high levels of dimensional stability, resistance to wear and bursting, and duration over time.

Installation:

The device can be mounted either directly onto the pump or between the pump and the first service.

If the input pressure of the device exceeds 145 PSI, install a pressure reducer between the pump and the device itself.

No tap can be mounted between the pump and the device.

It is essential to mount the device with the flow arrows pointing upwards (fig. A).
It is recommended to connect the output of the device to the system by means of a ball valve and flexible tube (fig. B).

Before starting the device check that the pump is correctly primed.

Installation Wiring Diagram - 115VAC 2-Wire Pumps
For 115VAC motors exceeding 16 full load amps, use magnetic starter to avoid damage to MASCONTROL. See separate magnetic starter wiring diagram.


 

Installation Wiring Diagram - 230VAC Single Phase 2-Wire Pumps
For 230VAC motors exceeding 20 full load amps, use magnetic starter to avoid damage to MASCONTROL. See separate magnetic starter wiring diagram.

Use MASCONTROL in bypass when friction loss is excessive.
The main bypass piping must not exceed 1.5”, while the system pipe could be bigger.

For minimal delivery demands, the application of a small expansion tank downstream from the MASCONTROL allows for reducing the pump start-ups .
(Example: a glass of water, ice-making machine, inverse osmosis systems, or old systems with small losses).

It is recommended to preload the expansion tank at a slightly lower value than the restart pressure calibration value of the device.
(Example : MASCONTROL calibrated at 44 PSI, tank preloaded at approximately 42 PSI).
