PLEASE READ BEFORE PROCEEDING WITH INSTALLATION
FAILURE TO READ AND CONSIDER SAFETY INSTRUCTIONS IN THIS MANUAL OR ON
BEST CONTROL MAY RESULT IN PERSONAL INJURY OR SERIOUS DAMAGE TO PIPING
OR FIXTURES !
Hazardous pressure.
Under certain conditions, submersible pumps can develop extremely high pressure. Install a
pressure reducing valve to limit pressure to safe levels for application. Be sure well is
equipped with a pressure relief valve.
Do not allow pump, BEST CONTROL, piping, or any other system component containing water to
freeze. Freezing may damage system, leading to injury or flooding. Allowing BEST CONTROL or
system components to freeze will void warranty.
Hazardous voltage.
Can shock, burn or cause death.
Install ground and wire BEST CONTROL according to local code and National Electrical Code
requirements.
Depressurize the system and disconnect power supply before installing or servicing BEST CONTROL.
Make sure line voltage and frequency of power supply match motor nameplate voltage and frequency
and BEST CONTROL voltage and frequency.
Install BEST CONTROL according to all plumbing, pump and well code requirements.
Pipe joint compound can cause cracking in plastic. Use only Teflon tape when sealing joints in plastic pipe or
connecting pipe to thermoplastic pumps and BEST CONTROL.
For threaded conduit opening - To be used with UL Listed or Recognized, liquid-tight non-metallic (plastic)
conduit fittings.
The manufacturer is not responsible or liable for damage due to improper
installation or use
.
This is the safety alert. When you see this symbol in this manual, look for one of the following
signal words and be alert to the potential for personal injury.
Warns about hazards that will cause serious personal injury, death or major property
damaged if ignored.
Warns about hazards that can cause serious personal injury, death or major property

” MPT.

Do not over thighten water connections, especially when installing with metal
couplings. Damage to BEST CONTROL may result.
HYDRAULIC CONNECTION TO THE SYSTEM
Prepare all threads with Teflon tape only.
CONDUIT CONNECTIONS
Open the electronic box cover by removing
the six screws from the cover.
Line voltage and pump wires to the BEST CONTROL should be supplied through “liquid-
tight” nonmetallic conduit fittings rated “NEMA 12” or “UL type 12” to achieve NEMA Type
12 enclosure rating.
Failure to install unit without use of liquid tight conduit voids warranty!

OK NO
Always install BEST CONTROL with flow arrows in the
vertical position.
Electronic box must be level.
Do not install any tee or tap between pump and BEST CONTROL unit.

SUBMERSIBLE PUMP
TYPICAL BEST CONTROL INSTALLATION ON SURFACE AND SUBMERSIBLE PUMPS

If pressure exceeds 145 psi, install a pressure reducing valve.
ABOVE GROUND PUMP
BEST CONTROL can be installed on above ground and submersible pumps for residential, domestic irrigation and booster systems.
TYPICAL BEST CONTROL INSTALLATION ON ABOVE GROUND AND SUBMERSIBLE PUMPS

BEST CONTROL INSTALLATION GUIDELINES AND WARNINGS
PLEASE READ PRECAUTIONS AND WARNINGS ON PAGE 2 BEFORE PROCEEDING WITH INSTALLATION
REMOVE PRESSURE SWITCH FROM PUMP AND WIRE BEST CONTROL DIRECTLY TO PUMP.  BEST CONTROL operates the pump to its maximum pressure.
 Install BEST CONTROL only in clean water applications.
 Always confirm pump and system characteristics before installation, see page 5.
 Confirm electrical characteristics of pump motor before installation, e.g. full load amps and voltage.  Must always be installed in the vertical position, flow arrows up, electronic box level.
 Do not install any tap or tee between the pump and the BEST CONTROL.  Install a pressure reducing valve between pump and BEST CONTROL when maximum pressure generated by
the pump exceeds 145 psi.
 Install a gate valve and a pressure gauge after the BEST CONTROL unit. This allows testing of the pump and BEST CONTROL unit for efficiency and to confirm pump pressure.
WHEN TO USE PRESSURE TANK
- 6 -
A small pressure tank ( 1/2 to 2 gallons ) may be used: 1 - In case of pumps using BIAC switch starting system motors. It allows bi-metal switch strips to cool in such a way to warrant the regular pump restart.
2 - In case of minimal delivery demands.
It allows for reducing the pump start-ups. ( Example: a glass of water, ice-making machine, inverse osmosis systems, or old systems with small losses).

Both BEST CONTROL models 1 1/4” and 1” can be provided with three different factory preset cut
-in pressures. Use the appropriate guidelines below for the specific model.
A - BEST CONTROL preset cut-in pressure 22 psi model:
• Max pressure generated by the pump must be at least 45 psi.
• The column of water between BEST CONTROL and the highest tap must not exceed 50 feet.
• BEST CONTROL unit operates from min 22 psi to the max pressure generated by the pump.
B - BEST CONTROL preset cut-in pressure 32 psi model:
• Max pressure generated by the pump must be at least 55 psi.
• The column of water between BEST CONTROL and the highest tap must not exceed 70 feet.
• BEST CONTROL unit operates from min 32 psi to the max pressure generated by the pump.
C - BEST CONTROL preset cut-in pressure 42 psi model:
• Max pressure generated by the pump must be at least 75 psi.
• The column of water between BEST CONTROL and the highest tap must not exceed 90 feet.
• BEST CONTROL unit operates from min 42 psi to the max pressure generated by the pump.
CALIBRATION
- 7 -
In the event the pump pressure does not reach the value stated above, the unit will go into
Failure mode and will not restart the pump.
In the event the high of the water column exceeds the level indicated, the unit will not restart the
pump.
To overcome these problems install BEST CONTROL at a higher level in order to recreate the
above mentioned conditions, otherwise use higher cut-in pressure models.

ELECTRICAL CONNECTIONS
Electrical connections should made by a qualified professional in compliance with
applicable local codes and National Electric Code.
ALWAYS SHUT OFF POWER FOR INSTALLATION OR SERVICE.
Check voltage of pump and supply to determine pump motor FLA and follow applicable
BEST CONTROL wiring diagram. If pump motor FLA exceeds BEST CONTROL rating, use
magnetic starter wiring diagram for the applicable voltage ( see pages 12, 13).
Use Copper Conductors only.
Use 140 / 167 ˚F wire.
Use minimum 13 AWG wire.
Device must be properly grounded.
Always remove pressure switch from surface pump and wire BEST CONTROL
directly to pump.

Use a contactor when:
 On 115V installations pump motor full load amps exceed 16 FLA.
 On 230V installations pump motor full load amps exceed 20 FLA.
 On all three-phase applications.
Remember, match coil voltage on contactor with BEST CONTROL voltage.
Either 115V or 230V coils may be used.
Use of magnetic starter to avoid damage to the device is determined by pump motor.
