Installation
In order to safely use this product, familiarize yourself with this pump and also with the liquid
(chemical, etc.) that is going to be pumped through the unit. This pump is not suitable for many
liquids.
For installations where property damage might result from an inoperative or leaking pump due to
power outages, discharge line blockage, or any other reason, a backup system(s) should be used.
Failure to follow any warning can result in personal injury and/or property damage.
1. Locate pump as close to the fluid source as possible, thus making the suction line as short and
direct as possible.
2. Attach piping suction line to suction inlet and piping discharge line to discharge outlet. Avoid using
looped section of pipe or fittings which might permit air to compromise airtight pipe connections.
IMPORTANT: If plastic or fabric hose is used for the suction piping it should be of a reinforced type so
as not to collapse under suction.
3. Support the piping independently of the pump.
4. Laing circulators are lubricated by the pumped fluid. How they are mounted and the condition of
the water in the system are important. THOROUGHLY CLEAN and FLUSH the system before installing
the circulator. If the fluid contains a high level of dissolved solids such as dirt, sediment, or products of
corrosion, a strainer and/or filter should be installed at least 12” before the inlet to the circulator.
Electrical
These instructions must be followed to reduce risk of electrical shock. All work should be performed
by a qualified electrician and in accordance with the current national and local electrical codes and
regulations. Consult the nameplate for electrical data. The motor is impedance protected.
Make certain that a properly sized circuit is available. Wire size should be based on the current
carrying (amp) capacity of the conductor. The circulator must be grounded in accordance with the
current national and local codes. Ground wire should be copper with current capacity at least equal
to that of the wire carrying power to the circulator. Observe all minimum code requirements for your
jurisdiction.
For circulators supplied with a power cord, the current carrying capacity of the cord is suitable for
proper operation. Make certain the receptacle is properly configured and in good working order.
Check to make certain that the circuit is properly sized for the load.
Circulators intended for hard wire applications are supplied with 6” pigtails of proper current carrying
capacity and with a knockout in the motor end cap. Leads suitable for at least 194ºF (90ºC) should be
used and connected to the pigtails or directly to the terminals as indicated in the electrical
compartment. Grounding wire should also be suitable for 194ºF (90ºC) and should be connected to
the grounding terminal as indicated in the electrical compartment.
Isolation valves are recommended for both sides of the circulator. Valves should be positioned to avoid
leakage onto the motor and electrical compartment. All elbows, tees, and sharp bends in the piping
should be installed sufficiently upstream or downstream of the suction and discharge ports. Avoid
welding or soldering close to the circulator, which could cause damage to the unit.
Mounting
For installation purposes the arrows on the side of the pump housing indicate the direction of water
flow through the circulator. Check to make sure the circulator is adequately supported and that
neither the circulator nor the piping is severely stressed. Install the circulator at a point closest to the
highest static pressure point, but above the absolute lowest point in the system to avoid dirt and
sediment build-up. If required by application and code, install a safety relief valve to protect against
over temperature and pressure. Do not mount with the motor above the impeller. This can cause the
circulator to run dry leading to premature failure of the circulator which voids the warranty. Refer to
the figures below for proper orientation before installing the circulator.
