INSTALLATION
These important instructions must be followed for satisfactory
performance of your pump.
Before installation, check your local electrical and plumbing
codes.
Provide proper basin size to allow the pump to operate
without restrictions. A two- to five-minute run time is
recommended. Also, minimum 24" diameter recommended.
Make sure basin is free of string, cloth, nails, gravel, etc.
before installing pump.
Do not set pump directly on the bottom of basin pit if it is
not solid. Raise the pump by placing bricks or concrete
blocks underneath it.
Use steel or plastic pipe for all connecting lines between
pump and sewer outlet.
NOTE: Some city regulations do not allow installing a pump
with plastic pipe. Check local regulations.
In applications where the pump may sit idle for months at a
time, it is recommended that the pump(s) be cycled every
month to ensure the pumping system is working properly
when needed.
A check valve should be installed in discharge pipe, at least
12" above the discharge outlet of the pump.
An audible alarm system for high water conditions should
be installed in every pump for greater protection.
NOTE: Alarm is for indoor use only. Contact your Myers
distributor for other panel applications.
Do not bend cord. This will cause a crimp in the vent tube
and switch failure will occur. Pump should be plugged into a
single outlet, where vent tube can “breathe.” Blocking tube
or bending cord will void the warranty.
Connect to power source using 3-prong grounded AC
receptacle. Do not remove ground pin from electrical plug.
Do not use an extension cord.
For proper automatic operation make sure the pump power
cord is plugged into the back of the piggyback receptacle
on the float switch cord.
Use pump partially or completely submerged for pumping
(temperature to 140° F). Unit will pump will pump solid
materials up to 2" (spherical) in diameter.
Do not pump flammable liquids, strong
chemicals or salt water.
