Pre-Installation; Wiring Connections - Master Pumps 123323 Manual Del Usuario

Carefully read and follow all safety instructions in this manual
or on pump.
This is the safety alert symbol. When you see this symbol on
your pump or in this manual, look for one of the following
signal words and be alert to the potential for personal injury!
DANGER warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
WARNING warns about hazards that can cause
serious personal injury, death or major property damage if ignored.
CAUTION warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are important
but not related to hazards.
To avoid serious or fatal personal injury and possible property
damage, carefully read and follow the safety instructions.
1. Under certain conditions, submersible pumps
can develop extremely high pressure. Install a
pressure relief valve capable of passing entire
pump flow at 75 PSI (517kPa) when using an air
over water pressure tank. Install a pressure relief valve capable
of passing entire pump flow at 100 PSI (690 kPa) when using a
pre-charged pressure tank.
Do not allow pump, pressure tank, piping, or any other system
component containing water to freeze. Freezing may damage
system, leading to injury or flooding. Allowing pump or system
components to freeze will void warranty.
2. Can shock, burn or cause death. To avoid
dangerous or fatal electric shock hazard, use
Hazardous
pump only in a water well.
voltage
Risk of dangerous or fatal electrical shock. Do not
install this pump in any pond, river, or other open body of water that
could be used for swimming or recreation. Do not swim, wade or play
in a body of water in which a submersible pump has been installed.
Install, ground and wire pump according to local and Cana-dian
Electrical Code or National Electrical Code requirements
that apply.
Disconnect electrical power supply before installing or
servicing pump.
Make sure line voltage and frequency of power supply match
motor nameplate voltage and frequency.
3. Install pump according to all plumbing, pump and well code
requirements.
4. Test well water for purity before using the well. Call your local
health department for testing procedure.
5. During installation, keep well covered to prevent leaves and
foreign matter from falling into well. Foreign objects in well
can contaminate water and cause serious mechanical damage
to pump.
6. Pipe joint compound can cause cracking in plastics. Use only
teflon tape when sealing joints in plastic pipe or connecting pipe
to thermoplastic pumps.

PRE-INSTALLATION

Inspect pump and motor for delivery damage. Report any damage
immediately to shipping carrier or to your dealer.
Well driller should thoroughly develop well (pump out all fine sand and
foreign matter) before pump is installed. (See Initial Startup).
Pump performance is based on pumping clear, cold water with no
entrained air.
Warranty is void in the following conditions:
• Pump has pumped excessive sand which can cause premature
wear to pump. (See Initial Startup)
• Water is corrosive.
• If entrained gas or air present in water being pumped, reduce flow
and cause cavitation which can damage pump.
• Pump has been operated with discharge valve closed – severe
internal damage will result.
Install pump at least 15 to 20' (4.6 - 6.1M) below the lowest water level
reached with pump running (lowest draw-down water level), and at
least 5' (1.5M) above bottom of well.
ELECTRICAL
WIRING/GROUNDING
Hazardous
Can shock, burn, or cause death.
voltage
Permanently ground pump, motor
and control
power supply to motor.
Ground pump and motor in accordance with all codes and ordinances
that apply. Use copper ground wire at least as large as wires carrying
current to motor.
Motor is supplied with copper ground wire. Splice to copper
conductor that matches motor wire size specified in Table 3. See
"cable splicing" under Installation.
Permanently ground pump, motor and control box before connecting
power cable to power supply. Connect ground wire to approved
ground first, then connect to equipment being installed.
Do not ground to gas supply line.
Fire and electrical shock hazard. If using a power
supply wire larger than No. 10 (5mm
No. 8 (7mm ) wire) between pump and control box, run wire to
2
separate junction box. Connect junction box to control box with a No.
10 (5mm ) wire.

For more information, contact your local code officials.

WIRING CONNECTIONS

All wiring must meet Canadian Electrical Code or National Electrical
Code and local code requirements.
Use only copper wire for connections to pump and control box.
To avoid over-heating wire and excessive voltage drop at motor,
be sure wire size is at least as large as size listed in Table 3 for your
horsepower pump and length of wire run.
NOTICE: See Installation Wiring Diagrams for typical wiring hook-ups
and control box identification.
