heaters on or off. Please note that you cannot "power cycle" the device from
this switch; only the tank heaters.
c. The fuse drawer holds two 250V 3A fuses to protect the AC tank heaters.
E. Dl Water lnlet: This is where the Dl water supply is to be connected by
the end user. The tting is either a 1/4" VCR Male tting or a 1/4"
compression tube tting depending on the conguration ordered. Ensure the
DI water source is equal to or better than UHP ( 18 mega ohm-cm). This is
also where a nitrogen gas supply is to be connected for the purpose of
draining the VDM300. Ensure that either uid is pressurized to 10 - 40 psig.
See Section 2-5-1 Inlet Connections for more details and instructions on how
to connect Dl water and/or N2 to the inlet.
F. Tank Drain: This is a 1/8" lnstant Tube Fitting. This is the outlet through
which the Dl water is drained from the tank. See Section 1-10 VDM300 lnter-
nal Layout and Basic Function for more details about the tank.

1-10 Internal Layout of VDM300 and Basic Function
Figure 1-5 below illustrates the internal layout of the VDM300 system. The
VDM300 has a titanium tank inside that serves as a reservoir for Dl water
and a Mass Flow Controller (MFC).The Dl water is heated to the vapor state
in the tank through the use of heaters attached to the tank and a heater
control system along with the vacuum outlet pressure. The liquid water level
is monitored by a level detection system (not shown in diagram) in the tank.
The MFC delivers the appropriate amount of Dl water vapor on demand
through the Dl water vapor outlet. The ll valve controls the ow of Dl water
into the tank which works in tandem with the level detection system to main-
tain the optimal amount of liquid Dl water in the tank for vaporization during
operation. The tank drain controlled by the drain valve allows the tank to be
emptied for maintenance and extended periods of downtime.

Remove the envelope containing the packing list. Unpack and inspect
the VDM300 and additional items for any possible shipping damage. The
VDM300 is shipped with two each 312 series replacement fuses for the
power entry module, a 6’ length of 1/8" O.D. Teon tubing, a ferrite core for
the control cable, the certicate of conformance/ nal test data and the Instal-
lation & Operations Manual. The tubing can be connected to the tank drain
when draining Dl water from the tank inside the VDM300. Contact Brooks if
there are any problems or if more information is required.
The following items can be purchased separately; these items are not neces-
sary for the installation and are not used for normal operation of the VDM300
but can be utilized for troubleshooting:
The Brooks Expert Support Tool (BEST) provides diagnostic tools and an
alternate access to VDM300 functions.
NOTE: The BEST must be installed on a separate computer in order to perform any
diagnostic function. Contact Brooks for information on purchasing the software.

2-5-1 Inlet Connections
Dl Water & Nitrogen lnlet: The VDM300 can be ordered with a 1/4" VCR
male tting or a 1/4" tube compression tting. This inlet is where the Dl water
source is connected for normal operation, or where the nitrogen source is
connected when draining the VDM300. It is up to the user to make sure that
the proper source is available for the particular mode of operation desired.
NOTE: The inlet pressure for both uid sources must be between 10-40 psig
for proper operation.
Tank Drain: The VDM300 has a 1/8" lnstant Tube Fitting. This is the port
where the water will drain out of the tank of the VDM300.Make sure that
the 1/8" drain tube is properly connected to this port when draining the tank
The tubing should bottom out in the tting. Leave this drain line permanently
connected as repeated coupling and uncoupling can cause unnecessarily
damage the tubing.
2-5-2 Outlet Connections
Vapor Outlet: The VDM300 has a 1/2" VCR male tting for this connection.
The VDM300 is designed to deliver vapor into a vacuum so be sure that the
connection to the tool will remain at or below 200 Torr during normal
operation.
Because the internal MFC control valve is not a complete shutoff valve, it
is highly recommended that a shutoff valve be installed downstream of the
VDM300 to isolate it during device zeroing.
