Connecting The Calibration Gas Cylinder To The Dock(S); Single Cylinder To Single Dock; Single Cylinder To Multiple Docks - Honeywell IQ Express Reference Manual

2.7 Connecting the Calibration Gas
Cylinder to the Dock(s)
Connection requirements for calibration
gas cylinders vary with how many docks
will be connected to the cylinder.
For instructions on connecting the gas
cylinder to a single dock proceed to
section 2.7.1.
For instructions on connecting the gas
cylinder to multiple docks proceed to
section 2.7.2.

2.7.1 Single Cylinder to Single Dock

1. Insert the demand flow regulator into
the calibration gas cylinder.
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
toxic GAS port on the dock (see figure
2.7.1).
Figure 2.7.1 Gas Ports
4. Proceed to section 2.7.3 for further
instructions concerning the fresh AIR
port.

2.7.2 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 Honeywell Analytics 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 8 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
Honeywell Analytics (part number 12-
061) has a maximum output capacity of
3 liters per minute, so it can be used to
calibrate up to 8 docks simultaneously.
Do not connect more than 4 docks to a
single cylinder of calibration gas while
using the 12-061 demand flow
regulator.
The 54-46-115 manifold is comprised of:
(1) small black elbow fitting
(7) small black T-fittings
(6) pieces of gas tubing 5" long
(1) piece of gas tubing 10" long
(1) piece of gas tubing 1" long
54-46-115 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 8 docks will be used, no
modifications are necessary. For 2 to
7 docks, begin by separating the
tubing at the location described below.
Once this is accomplished, set the
separated parts aside. The section
that will be used is shown in the
following images (depending on the
number of docks).

Manifold for three docks
Manifold for seven docks
3. Each dock is delivered with a 24"
piece of tubing with a white quick
disconnect fitting, which is normally
