Section I Safety
Warnings
DANGER
WARNING
CAUTION
Make sure you read and understand all instructions and safety precautions listed in this manual before installing or operating your CDU. If you have any questions concerning the operation of your CDU or the information in this manual, contact our Sales Department for assistance.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in serious injury or death. This signal word is limited to the most extreme situations.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in serious injury or death.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.
Performance of installation, operation, or maintenance procedures other than those described in this manual may result in a hazardous
situation and may void the manufacturers warranty.
Transport the CDU with care. Sudden jolts or drops can damage the
CDU.
Do not attempt to defeat any of the interlock switches or safety features built into the CDU.
Observe, and never remove, all warning labels.
Never operate damaged or leaking equipment.
Never operate the CDU without cooling fluid in the fluid reservoir.
Process fluid are subject to environmental regulatory restrictions. Do not dispose into the environment. In the United States use proper OSHA approved location for disposal.
Use remote lockout tag-out procedures prior to servicing the CDU. Make sure the CDU is off before connecting or disconnecting the power cord or other cables.
Always turn off the CDU and disconnect the power cord from the power source before performing any service or maintenance procedures, or before moving the CDU.
Always empty the fluid reservoir before moving the CDU.
Never operate equipment with damaged power cords.
Refer service and repairs to a qualified technician.

EMO Circuit
Each of the following safeties is part of the test system Emergency Off (EMO) circuit. The tripping of either of these safeties will cause power to be dropped to the CDU by the test system. The EMO circuit should not exceed 10A @
24VDC.
High Air Temperature (TSH-101)
This safety opens the EMO circuit when the air temperature safety switch detects a temperature inside the CDU greater than 70°C. The temperature switch is self-resetting at a temperature of 54°C or below.
Lockout/Tagout (LOTO)
Before performing Chiller maintenance, the energy sources associated with the
Chiller system must be lockout and tagged out (LOTO).
Since the CDU itself has no electrical LOTO, lock out power remotely.
Electrical LOTO can be provided by:
Disconnecting main power at the facility power source prior to the system controller cabinet.
The unit does not provide LOTO for the facility water flow. An external usersupplied device is required.
In addition, follow all local facility LOTO directives.

Monitoring for Fluid
Loss
Each line on the Reservoir Gauge represents approximately 1/10 of a gallon.
On a routine basis check and record the fluid level. If the fluid level is dropping at a rate faster than indicated by the specification then perform the following:
1. Ensure the Tank Fill Port and the Tank Auxiliary Port Cap are properly installed and on hand tight.
2. Check all sanitary gaskets to insure that they are properly installed and
are on according to the Torque Specification Sheet on page 86.
3. Look for signs of a leak at all connections and solder joints.
4. If none of the above yield any results, use a Halogen Leak detector on each connection and joint.
5. Check for leaks at the Test Equipment per your procedures.

Swagelok Tube Fitting
Instructions
1
Installation
1. Insert tubing into the Swagelok tube fitting.
2. Make sure that the tubing rests firmly on the shoulder of the tube fitting body and that the nut is finger-tight.
3. Scribe the nut at the 6 oclock position.
4. While holding fitting body steady, tighten the nut 11/4 turns to the 9 oclock position. Note: For 1/16, 1/8, and 3/16 in; 2, 3, and 4 mm tube fittings, tighten the nut 3/4 turn to the 3 oclock position.
Installation in High-Pressure Applications and High Safety-Factor
Systems
1. Follow steps 1 and 2 of the Swagelok Tube Fitting Instructions.
2. Tighten the nut until the tubing will not rotate freely by hand.
3. Follow steps 3 and 4 of the Swagelok Tube Fitting Instructions.
Gageability On initial installation, the Swagelok gap inspection gauge assures the installer or inspector that a fitting has been sufficiently tightened.
Position the Swagelok gap inspection gauge next to the gap between the nut and body.
If the gauge will not enter the gap, the fitting is sufficiently tightened.
If the gauge will enter the gap, additional tightening is required.
- 87 -
Reassembly Instructions You may disassemble and reassemble a
Swagelok tube fitting, port connector, cap, and plug many times.
1. Insert tubing with pre-swaged ferrules into the fitting body until the front ferrule seats.
2. Rotate the nut with a wrench to the previously pulled-up position. At this point, a significant increase in resistance will be encountered.
3. Tighten slightly with a wrench. Note: Do not use the gap inspection gauge with reassembled fittings.
Do not mix or interchange parts with those of other manufacturers.
