Recirculation Pump Air Cooling System
The Aquarius
D.I. Water Heating Systems feature a pump air cooling system that
optimizes the pump life and protects the pump motor from over-temperature
conditions. The temperature of the pump motor is continuously monitored and during
recirculation should the temperature of the pump rise above the Factory defined
“Pump Motor Temperature Set Point” the pump air cooling system will initiate. The
pump air cooling system will lower or maintain the pump motor temperature and
keep it at a safe operational temperature. The pump air cooling system will
disengage or shut off once the temperature of the motor is below the Factory defined
“Pump Motor Temperature Set Point”. It is recommended that the pump air cooling
system be utilized for optimum performance. Please follow the Pump Air Cooling
System Set Up and Calibration procedures prior to operation of the Recirculation
feature.
The Pump Air Cooling System Specifications are listed below.
