Note that the tubing assemblies for the
standard and the enhanced versions of
the IQ Express Docks are different. The
tubing assembly for the enhanced
versions includes a black elbow fitting
that should be located just above the
regulator.
3. Connect the end of the tubing with the
white quick disconnect fitting to the toxic
GAS port on the IQ Express Dock (see
figure 2.7 above for location of the GAS
port).
4. Proceed to section 2.7.3 for further
instructions concerning the fresh AIR
port.
2.7.2 Single Cylinder to Multiple
Docks
When a series of IQ docks is 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 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
Express 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. For
enhanced docks, remove the black
elbow fitting entirely from the 24” piece
of tubing and run the smaller diameter
tubing directly from the docks to the
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 at this point 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.
