Pump Air Cooling System Set Up:
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.
Provide a steady air supply source for the pump air cooling system as detailed
below. It is highly recommended that this air supply source be independent from
other system requirements for air.
1) Locate the 1/2” FNPT air supply port for the pump air cooling
system at the back of the Aquarius
D.I. Water Heating System.
Please refer to the Facility Diagram in
SECTION II
for its specific
location.
2) Install a tube connector to the 1/2” FNPT air supply port. It is
recommended that a 1/2” MNPT tube connector with a minimum
tube size of 3/8” to a maximum tube size of 1/2” be used.
3) Connect the appropriate air supply tube to the respective 1/2”
MNPT tube connector.
4) Provide 60 psi maximum of steady air supply pressure. Minimum
needed should be equivalent to or greater than the air regulator
setting. See plumbing schematic for setting.
5) Proceed with the Pump Air Cooling System Calibration
procedure.
