Pump Air Cooling System Calibration:
Calibration of the pump air cooling system is necessary once the air supply
connection for the pump air cooling system has been completed. This is achieved
by regulating the air pressure of the pump air cooling system when it is active. To
perform this calibration procedure access to the interior enclosure of the Aquarius
D.I. Water Heating System with the system powered ON is required. Please refer
to the PF2000 Controller Manual for more information on the HMI/Touch screen
operation of the Aquarius
D.I. Water Heating System.
Please take extreme cautionary measures as live voltage will be present in
Aquarius
D.I. Water Heating System during the Pump Air Cooling System
Calibration procedure.
1) Take the appropriate steps necessary to have the Aquarius
D.I.
Water Heating System powered ON with the enclosure door
open. Please note that the Door Interlock switch will prevent the
unit from powering ON when the enclosure door is open.
2) Verify that an adequate steady supply of air is being supplied to
the pump air cooling system (60 psi maximum).
3) Locate the pump air cooling system pressure regulator/gauge in the
heater compartment of the Aquarius
D.I. Water Heating System
and take note of the air pressure reading on the pressure gauge.
Please refer to the Mechanical Layout Drawing in
SECTION II
for
its specific location.
4) Turn the Aquarius
D.I. Water Heating System ON, once again
with the enclosure door open.
5) Verify that the Recirculation System is enabled which is indicated
by an illuminated yellow
“Enabled”
key on the
System Status
screen. If the Recirculation System is not enabled press the
DISABLED
key.
6) Send the unit into Recirculation mode by providing a closed
“Recirculation Signal”.
7) Once the unit is in Recirculation mode, activate the pump air
cooling system temporarily by pressing the
“Pump Air Cooling
System Calibration ON/OFF”
key located on the
System
Calibration screen
.
8) The pump air cooling system will activate for approximately 60
seconds and then shut off. Please note that the air pressure
reading on the pressure gauge may drop when the pump air
cooling system is actively cooling.
