Installation

2 Installation
2.1 Installation safety
2.2 Installing the inlet temperature indicator assembly
1. If the pump has previously been run on process start by performing the following steps:
Allow the pump system to cool to a safe temperature before you start maintenance work.
Isolate the inlet and exhaust pipe work from other processes. Vent and purge the pipe work before you start
any installation or maintenance work.
Vent and purge the dry pumping system before you start any installation or maintenance work.
Isolate the dry pumping system and other components in the process system from the electrical supply so
that they cannot be operated accidentally. Note that the emergency stop switch on the dry pumping system
is not an electrical isolator.
2. Remove the inlet temperature indicator assembly from the packaging, undo the compression nut and remove the
taper thread part of the compression fitting.
WARNING
Before installation is attempted refer to the CXS pumping system instruction manual to ensure
safety and compliance.
WARNING
Ensure that the pump's electrical supply is fully isolated before undertaking the installation.
WARNING
The surfaces of the inlet and exhaust can be very hot when the CXS system is running. Allow these
surfaces to cool to a safe temperature before installing the inlet/exhaust pressure indicator.
WARNING
Leak test the system after installation and seal any leaks found to prevent leakage of dangerous
substances out and leakage of air into the system.
WARNING
Personal protective equipment should be checked and used as specified by its supplier. Hazardous
chemicals that have been pumped are located within the pumps and piping. Use of suitable
protective gloves and clothing along with a respirator is recommended if contact with substances
is anticipated. Particular caution should be exercised when working with fluorinated materials
which may have been exposed to temperatures greater than 260°C. Refer to Edwards Material
Safety Data Sheets for detailed information.

Installation
Note: The compression fitting has been pre-swaged onto the temperature gauge stem to ensure correct
positioning in the inlet spool.
3. Remove the appropriate 1/2” BSP plug from the inlet spool located above the inlet isolation valve as shown in
Figure 1.
4. Apply a suitable thread sealant such as Loctite®577 to the taper thread of the compression fitting and screw
into the 1/2” BSP connection. Insert the temperature gauge stem into the compression fitting and retighten the
compression fitting nut ensuring correct orientation as shown in Figure 2.
5. Leak test the inlet temperature indicator assembly and seal any leaks found.

Return the equipment or components for service
Before you send your equipment to us for service or for any other reason, you must send us a
completed Declaration of Contamination of Vacuum Equipment and Components – Form HS2. The
HS2 form tells us if any substances found in the equipment are hazardous, which is important for
the safety of our employees and all other people involved in the service of your equipment. The
hazard information also lets us select the correct procedures to service your equipment.
We provide instructions for completing the form in the Declaration of Contamination of Vacuum
equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
 If a pump is configured to suit the application, make a record of the configuration before
returning the pump. All replacement pumps will be supplied with default factory settings.
 Do not return a pump with accessories fitted. Remove all accessories and retain them for
future use.
 The instruction in the returns procedure to drain all fluids does not apply to the lubricant in
pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/, follow the procedure in
HS1, fill in the electronic HS2 form, print it, sign it, and return the signed copy to Edwards.
Note: If we do not receive a completed HS2 form, we will not accept the return of the
equipment.
