Install Instructions

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.
