1. Connect an AC-powered terminator supplied by the manufacturer to
the open coupling of the BNC tee connector at one end of the trunk
cable.
2. Connect the AC-powered terminator to an applicable AC power
source.
3. Install a passive terminator on the open coupling of the BNC tee
connector at the other end of the trunk cable.
Connect to power

Electrical shock and fire hazards. Replacement power cords must:
• Have the correct plug style for the outlet connection
• Have a rating sufficient for the supply voltage and current. Refer to
the requirements in the Specifications section.
• Meet or exceed local electrical code requirements
W A R N I N G
Electrocution hazard. Only the hot (L) connection is fused. Connect
only single phase power sources to equipment. Do not use bi-phase or
poly-phase supply sources.
1. Connect the supplied power cord to the analyzer, then to a mains
electrical outlet with protective earth ground.
2. For non-integrated C80 controllers, connect the power adapter to the
controller power cable, then a mains electrical outlet with protective
earth ground. Refer to Figure 5

Tighten a new ferrule 1¼ turns the first time it is tightened. Then, only tighten the
ferrule 1/8 turn to make a connection. Do not tighten the fittings more as this may
cause damage to the fittings or ferrules and cause leaks.

A1000—Do not use the supplied PFA tubing for installations when the
sample is:
• More than 75 °C (167 °F) and more than 620 kPa (90 psig)
• More than 85 °C (185 °F) and more than 550 kPa (80 psig)
For these installations, or for any application where the use of PFA
tubing is a concern, use high-grade ¼-in. (OD) PTFE, FEP, PVDF or
316 stainless steel sample tubing instead.
A1000XP—Do not use the supplied PFA tubing. The A1000XP analyzer
is designed for the purest water systems so use non-permeable tubing,
®
such as Kynar or 316L electro-polished stainless steel for the sample
™
tubing. Teflon PFA/PTFE can be used, but there is a potential for
sample corruption due to the permeability of the tubing. Keep the
distance between the sample point and the analyzer as short as
possible.
1. Plumb the sample tubing. Refer to
2. When the sample is more than 50 °C (122 °F), install a heat
exchanger in the sample line upstream of the analyzer or erratic
readings will occur. The heat exchanger is supplied by the user.
