System Shut Down Procedure
Before shutting down the Aquarius
DI Water Heating System verify that doing so will
not adversely affect other equipment, machinery, and/or processes and that it is safe
to do so. Prior to powering down the system, place the Aquarius
control system into
Standby mode. (Refer to the
PF2000 Controller Manual
for more detailed
information.) Once the unit is in Standby mode, power down the system by pressing
the OFF button which is located on the front of the Aquarius
DI Water Heating System.
The indicating lamp on the ON button will de-energize and the touchscreen will turn
off. Please note that electrical power will remain present within the system until the
Aquarius
DI Water Heating System has been disconnected from the electrical energy
source. To turn on the unit, simply press the ON button located next to the OFF button.
The Aquarius
DI Water Heating System will always power up in the Standby mode.
It is ultimately the responsibility of the user to verify and provide adequate isolation of
all energy sources, i.e. electrical power, pneumatic air (CDA) and D.I. water. The
process fluid within this system may become pressurized from outside flow sources.
It is the user’s responsibility to verify that pressure within the system has been
relieved externally prior to servicing, in order to prevent exposure to hazardous fluid,
in this case, heated de-ionized water.
Certain energy isolation devices may be provided with the Aquarius
DI Water
Heating System as an option, such as an electrical disconnect switch and/or pneumatic
AOV valves for process fluids. If provided, the electrical disconnect switch will be
mounted in an enclosure located on the back of the Aquarius
DI Water Heating
System. If provided, the pneumatic AOV valves will be located inside the enclosure in
the heater/plumbing section. While energy isolation devices may be provided with the
Aquarius
DI Water Heating System, it is the responsibility of the user to determine if
these options are sufficient and safe based on their requirements.
If the unit is to remain powered off for an extended length of time, it is recommended
to disconnect and isolate all energy sources to the Aquarius
DI Water Heating
System, such as electrical power, pneumatic air (CDA) and DI water.
