2. Slide the open end of the tubing
assembly over the regulator.
3. Connect the end of the tubing with
the white quick disconnect fitting to
the GAS1 port on the dock (see
figure 2.7).
4. Proceed to section 2.7.5 for further
instructions concerning the fresh AIR
port.
2.7.2 Multiple Cylinders to Single Dock
The PHD6 includes 4 calibration gas inlet
ports to provide calibration flexibility for
gas detection programs that include
many detectors with a wide variety of
sensors.
To connect more than one cylinder to the
IQ6 Dock, follow the instructions in
section 2.7.1 and repeat as many times
as necessary to connect cylinders to the
GAS2, GAS3 and GAS4 inlet ports on
the back of the dock.
Note: The IQ6 Dock Software must be
programmed with port-by-port details
of the gases used. See section 3.2.1
below.
2.7.3 Single Cylinder to Multiple Docks
When multiple IQ docks are connected to
a single cylinder of calibration gas, a
manifold is used to disperse the
calibration gas from the cylinder to the
docks.
The manifold is Sperian part number 54-
46-115 and includes a detailed
instruction sheet for its use. The
manifold comes with tubing and fittings
necessary for connecting up to 4 docks
to a single cylinder of calibration gas.
Note: Do not exceed the output
capacity of your demand flow
regulator. Each IQ Express dock is
able to draw calibration gas at a
maximum rate of 0.75 liters/minute.
The demand flow regulator supplied
by Sperian Instrumentation (part
number 12-039) has a maximum
output capacity of 3 liters per minute,
so it can be used to calibrate up to 4
docks simultaneously. Do not
connect more than 4 docks to a single
cylinder of calibration gas while using
the 12-039 demand flow regulator.
The 54-46-115 manifold is comprised of:
(1) small black elbow fitting
(3) small black T-fittings
(2) pieces of gas tubing 5” long
(1) piece of gas tubing 10” long
(1) piece of gas tubing 1” long
54-46-0115 Manifold
1. Insert the Demand Flow Regulator
into the calibration gas cylinder.
2. Modify the tubing assembly as
follows depending on how many
docks will be connected. If 4 docks
will be used, no modifications are
necessary. For 2 or 3 docks, begin
by separating the tubing at the
location described below.
Once this is accomplished, set the
two parts aside. The section that will
be used is shown in the following
images (depending on the number of
docks).
Manifold for two docks
Manifold for three docks
Manifold for four docks
3. Each dock is delivered with a 24”
piece of tubing with a white quick
disconnect fitting, which is normally
used to connect a single gas cylinder
directly to a single dock. Connect the
white quick disconnect fittings to the
GAS ports on the docks and connect
the open ends to the manifold’s open
t-fittings.
At this point, tubing should run from each
dock’s GAS port to the t-fittings. There
should be no open T-fittings in the
procedure, but there should be one piece
of open tubing on the elbow fitting.
4. Connect the open piece of tubing on
the elbow fitting to the Demand Flow
Regulator.
