3 Product Description
3.1 Pump design
• The ecocirc XL is a large wet rotor pump with energy efficient, elec-
tronically commutated permanent magnet motor.
• The pump is designed for systems with variable flow rates to opti-
mize pump operation thus reducing energy consumption. The
pump can be set to any one of the multiple operating modes availa-
ble, with each designed for a specific application to achieve high
performance and maximum energy savings.
• A single pump can handle heating, cooling, and plumbing applica-
tions with a choice of cast iron, stainless steel, or lead-free bronze
pump body to handle HVAC and potable water applications. The
pumps are also suitable for a 50/50 percent water/glycol circulating
fluid. The built-in electrical overload and dry run protection provide
safety and protection from damage.
Intended use
WARNING:
California Proposition 65 warning! This product contains
chemicals known to the state of California to cause cancer
and birth defects or other reproductive harm.
The pump is suitable for:
• Potable hot water (only with bronze or stainless steel pump body
models)
• Hot water heating systems
• Cooling and cold water systems
The pump can also be used for:
• Solar systems
• Geothermal applications
Improper use
DANGER:
Do not use this pump to handle flammable and/or explosive
liquids.
WARNING:
Unintended use of the pump may create dangerous condi-
tions and cause personal injury and damage to property.
WARNING:
Do NOT install this pump in swimming pools or marine areas.
Failure to follow these instructions could result in serious per-
sonal injury, death and/or property damage.
THIS IS A NON-SUBMERSIBLE PUMP
WARNING:
Do NOT exceed the maximum working pressure of the
pump. This information is listed on the nameplate of the
pump.
WARNING:
The pump user interface values are to be used for reference
purposes only. Do not use the values given by the pump for
system balancing. If a level of flow and accuracy is required,
gauges that match the expected accuracy level must be in-
stalled independent of the pump.
NOTICE:
Do not use this pump to handle liquids containing abrasive, solid or
fibrous substances, toxic or corrosive liquids, potable liquids other than
water or liquids not compatible with the pump construction material.
Water pH must be maintained between 7-9 and water hardness must
not exceed 14 grains/ gallon.
An improper use of the product leads to the loss of the warranty.

The pump can be used with water/propylene glycol mixtures up to 50% with a maximum viscosity of 50cST at 14°F (-10°C). The pump has built-in overload and
thermal protection to protect the pump from overload due to increased fluid viscosity. Pump performance is based on 77°F (25°C). Therefore pumping of glycol
mixtures will affect max performance, depending on mixture concentration and temperature.
