POWER REQUIREMENTS
BlackStone pumps are designed to operate to specifications within
the following voltage ranges:
100 - 130 Volts for -1 models
200 - 240 Volts for -2 models
To ensure maximum performance, check the voltage at the point
of supply to verify that it is sufficient. It is recommended that you
install a 1 Amp circuit breaker between the pump and the power
supply. This will give additional protection to the internal circuit
and provide a convenient way to disconnect the power supply prior
to servicing the pump, if needed.
INJECTION POINT
• Choose an injection point that allows you to mount the
injection valve assembly vertically.
• The spring in the injection valve assembly (
HI 721004
) adds
approximately 1.5 bar of back pressure. If pumping into a
high back pressure, the spring should be removed.
OTHER CONSIDERATIONS
• If you are mounting the system to a wall, column, etc., be sure
it is strong enough to support the weight of the entire system.
• The ambient temperature of the pump, when in operation,
should be between 0 and 50°C (32 to 122°F) and should be
protected from direct exposure to outdoor elements (direct
sunlight, rain, extreme temperatures, high humidity, etc.).
• Generally speaking, the shorter the suction distance, the more
efficient the pump operates.
• The pump should be placed in a conventional location that
will allow easy access to the control and connections. It should
be placed so that regular visual inspections of the connections
and hoses are facilitated.
