These Picarro products comply with all required CE specifications. Intended Use The A0311 16-Port Distribution Manifold samples up to 16 gas sources in any order specified by the user. During operation, the selected line is routed through the valve into the analyzer. The 15 lines that are not selected terminate in the valve. - Page 10 • Unselected gas streams terminate at the valve. • Broadly compatible with all Picarro analyzers with the exception of those with known surface and chemical compatibility issues (such as the G2103, G2108, G2204, G2205, G2307, and PI2114).

CE label. This CE label is located on the rear of the instrument. Using a Picarro manifold in a manner not specified by Picarro may result in damage to the unit and render it unsafe to operate. -
Page 18: Unpacking
Do not stack boxes more than five high. Inspect the Shipping Box Picarro products are inspected and tested before leaving the factory. The shipping boxes provide proven safety from most dropping, crushing or spiking events. If the equipment arrives damaged, photograph the damage and contact Picarro (email pictures if possible) for consultation on best course of action. -

NOTE Figure 3 shows the accessories kit minus the power cable. Figure 3: A0311 or A0310 Accessory Kit Users who purchase an A0310 dual manifold kit will also receive a splitter cable (Figure 4) for the analyzer that allows the user to control both manifolds directly from the same communications port on the analyzer. -

(See warning in section 4.1, Installation Safety). CAUTION https://www.swagelok.com/en/catalog/Product/Detail?part=SS-400-P The A0311-S contains a universal power supply that accepts a power source range from 100-240 VAC, 50/60 Hz, 100 VA max. NOTE Figure 5 shows the accessories kit minus the power cable. -
Page 21: Recirculation Pump
While most Picarro instruments will run with one A2000 pump on the downstream side of the instrument (exception for this manual: A0310 configurations), the A0311-S kit comes with a second A2000 pump which should be connected to the A0311-S itself, following guidance in section 4.4, Connection Procedure A0311- S. -
Page 22: Installation
The instruments must be supported by a shelf or additional rails attached to the rack. If the A0311-S is mounted separately, it can be mounted using a front rack WARNING mount kit alone without additional support. -
Page 23: Confirm Manifold Receives Line Power
PERSONAL INJURY: When using the A0311-S with hazardous gases, cap all unused ports. In the event of a failure of the A0311-S vacuum pump, or if the user fails to turn on the pump, gas flowing from active ports could flow out of the unused/uncapped positions. - Page 24 16 unconnected and uncapped. Connect the A0311 power cable to line power. Turn the manifold ON using the On/Off switch on the A0311 back panel. With A0311 powered on, start the pump and then analyzer. This lets the analyzer recognize the newly installed hardware.

Headspace work is inevitably challenging from a mass conservation perspective.

10. Pharmaceutical Use (PI2114 + A0311-S) Pharmaceutical customers wishing to multiplex vapor-phase hydrogen peroxide (VHP, or VPHP) sampling will want to use the A0311-S manifold, as it contains compatible sample handling materials, and keeps all lines constantly refreshed to reduce position-to-position memory effects. Though this manifold is an excellent choice for this application, there are some important caveats about its use, which we outline here. -
