3. A magnetic motor starter should always be used to connect the motor to the
power supply. It is advisable to use thermal overload motor starters to provide
maximum protection for the motor and wiring. All cabling used on starters should
be secured with good quality cable clamps.
We recommend that the motor starters used feature a time delay trip on high
amperage to avoid nuisance trips on start-up. When the unit is started cold, over
amperage may be experienced for a short time due to the higher resistance of
the windings at lower temperatures.
If using a change over or solenoid valve, ensure that the voltage connected to
the valve matches that shown on the valve instructions or nameplate. Most
valves are rated for 110 Volts 60Hz or 220 Volts 50 Hz. Connection of these
valves to higher voltages may result in immediate valve failure.
WARNING! The electrical installation should be made by a qualified
electrician and in complete compliance with all NFPA 70 (National Electrical
Code) requirements along with all state and local code requirements. The
main disconnect and motors starters are assumed to be provided by
others.
4. Install the necessary relief valves and confirm their proper operation.
