surface. A waterproof mastic should be liberally applied to the under sur- faces of all four supporting legs of the cubicle system before placing it in position and bolting it in place.

4.1User Connections

All user connections are located around the periphery of the equipment panel (or cubicle) and are shown in the Outline Diagram.

4.1.1Electrical Power Connections

The system requires a 1 KW supply of 115 VAC, single-phase power. Power connections are made inside the control unit. Refer to the Intercon- nection Diagram. The electrical power service must include a high-quality ground wire. A high-quality ground is defined as having zero potential difference when measured to the power line neutral.

4.1.2Compressed Air Supply

The system requires a supply of compressed air at 80-120 psig.

NOTE: The air supply must be oil free. As a precaution, however, the air pressure line should contain a filter(s) to remove any traces of oil, supplied and maintained by the customer.

4.1.3Sample Connection

The sample water input (see Flow Diagram) is connected at the manual valve input. A flowrate of 1 gallon/minute, minimum, is recommended. Maximum flow is governed by the impedance of the delivery system.

4.1.4Signal and Alarm Output Connections

Signal and alarm output connections are made inside the control unit to terminal blocks mounted on the interface board. Refer to chapter 2 of control unit part of the manual.

NOTE: Signal circuit resistance, including accessory devices, must not exceed 1000 ohms. The alarm contact circuit must not draw more than 3 amperes at 250 VAC (None inductive), or 30VDC.
