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.
• Pumps are offered in cast iron and stainless steel options to handle
HVAC and potable water applications respectively. However, a sin-
gle stainless steel body pump can handle heating, cooling and
plumbing applications if so desired. 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:
This product can expose you to chemicals including lead,
which is known to the state of California to cause cancer and
birth defects or other reproductive harm. For more informa-
tion go to: www.P65Warnings.ca.gov
The pump is suitable for:
• Potable water with stainless steel 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, with suspended solids less than 100 PPM.
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.
