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!
indicates a hazard which, if not avoided, will
result in death or serious injury.
indicates a hazard which, if not avoided,
could result in death or serious injury.
indicates a hazard which, if not avoided,
could result in minor or moderate injury.
NOTICE addresses practices not related to
personal injury.
Carefully read and follow all safety instructions in this
manual and on pump .
Keep safety labels in good condition. Replace missing or
damaged safety labels.
Risk of electric shock . Can shock, burn or
kill. To avoid dangerous or fatal electric shock hazard,
use pump only in an effluent system. DO NOT install
pump in an open body of water ( a lake, swimming
pool, etc.).
• Install, ground and wire pump according to local
and Canadian Electrical Code or National Electrical
Code requirements that apply.
• Disconnect electrical power supply before installing
or servicing pump.
• Make sure pump nameplate voltage and frequency
match line voltage and frequency of power supply.
• Install pump according to all plumbing, pump and
well code requirements.
• Install an all leg disconnect switch in the power
supply near the pump.
Risk of explosion . Under certain conditions,
submersible pumps can develop extremely high pressure.
Install a pressure relief valve capable of passing entire
pump flow at 75 PSI.

Risk of sudden starts . Can cause electrical
shock and personal injury. Two-wire motors are equipped
with automatic thermal overload protection which will
open the circuit and stop the motor when a thermal
overload (excessive heating) exists. When motor cools,
overload will rest and motor will restart automatically.
This can cause the pump to start unexpectedly and
without warning.
Risk of freezing . Do not allow pump, 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.
General
Inspect pump for delivery damage. Report any damage to
shipping carrier or to Myers immediately.
Have any installation, repair, or service work done by
your Myers dealer.
Never run pump dry. During system operation, pump
must be submerged at all times.
Pipe joint compound can cause cracking in plastics. Use
only PTFE pipe thread sealant tape when sealing joints in
plastic pipe or connecting pipe to thermoplastic pumps.
Warranty is void in the following conditions:
• If pumped water is highly corrosive.
• If entrained gas or air is present in pumped water
that reduces the flow and causes cavitation.
• If pump has been operated with discharge valve
closed (severe internal damage will result).
Electrical Wiring / Grounding
Risk of electric shock . Can shock, burn or
kill. Permanently ground pump, motor and control box
before connecting power supply to motor.
Ground pump and motor in accordance with all codes
and ordinances that apply. All wiring must meet National
Electrical Code and Canadian Electrical Code (whichever
applies). Use copper ground wire at least as large as
wires carrying current to pump.
Pump is supplied with copper ground wire. Use only
copper wire for connections to pump.
