VESSEL DESCRIPTION:
Aurora Type 1060DP Tanks are ASME constructed, precharged
expansion tanks. They are designed to absorb the expansion
forces and control the pressure in a domestic hot water system
or a pressure booster system.
The system’s expanded water (typically from the system)
is contained behind a heavy duty – FDA approved – fixed
diaphragm preventing water contamination, tank corrosion and
waterlogging problems.
The factory set precharge for these tanks is 40 psig (276 kPa).

STEPS & PROCEDURE:
• Visually inspect the tank for damage, which may occur
during transit.
• Factory precharge pressure may not be correct for the
installation. Tank MUST be precharged to system design fill
pressure BEFORE placing into operation. Remove pipe plug
covering the valve enclosure. Check and adjust the charge
pressure by adding or releasing air for each application.
• If the system has been filled, the tank must be isolated
from the system and the tank emptied before charging. This
ensures all fluid has exited the bladder and proper charging
will occur.
• If the precharge adjustment is necessary, oil and water free
compressed air or nitrogen gas may be used. Check the
precharge using an accurate pressure gauge at the charging
valve and adjust as required. Check air valve for leakage.
If evident, replace the Schrader-type tire valve core. Do not
depend on the valve cap to seal the leak. After making sure
air charge is correct, replace pipe plug over the charging
valve for protection.
• Set tank in place and pipe system connection to system. Be
sure to include isolation valve(s) and drain.
• Purge air from system BEFORE placing tank into operation.
All models have system water contained inside bladder.
• When filling the system with water, open valves to tank to
ensure that any residual air in the tank is displaced by water.
• It is recommended that the precharge be checked annually to
ensure proper system protection and long life for the vessel.
