3 Installation
3.1 Safety
A suitably trained and supervised technician must install the Connection Kit.
Ensure that the installation technician is familiar with the safety procedures which relate to the products
pumped. Wear the appropriate safety-clothing when you come into contact with contaminated components.
Dismantle and clean contaminated components inside a fume-cupboard.
If the GV pump has been in operation, vent and purge it, then switch it off and allow it to cool to a safe
temperature before you start installation.
Isolate the GV pump and other components in the process system from the electrical supply so that they
cannot be operated accidentally.
Recheck the direction of rotation of the GV pump if the electrical supply has been disconnected.
Do not reuse ‘O’ rings and Co-Seals.
Leak test the system after installation and seal any leaks found, to prevent the leakage of dangerous
substances from the system, and the leakage of air into the system.
Do not use the lifting bolts fitted to the EH mechanical booster pump to lift a GV-EH combination pumping
system.
When you refer to another instruction manual, ensure that you obey the WARNINGs and CAUTIONs in the
manual.
3.2 Unpack and inspect
Remove all packing materials and protective covers and check the Connection Kit. If any item is damaged, notify your
supplier and the carrier in writing within three days. State the Item Number of the Connection Kit, together with
your order number and your supplier’s invoice number. Do not use the Connection Kit if it is damaged.
Check that you have received the items listed in the appropriate Table 2 to 4. If any item is missing, notify your
supplier in writing within three days.
If the Connection Kit is not to be used immediately, replace any packing and protective covers and store in suitable
conditions, as described in Section 5.1.
WARNING
Obey the safety instructions given below and take note of appropriate precautions. If you do not,
you can cause injury to people and damage to equipment.

3.3 Prepare the GV pump
1. If the GV pump has been in operation, vent and purge it with dry nitrogen or air, then switch it off and allow it
to cool to a safe temperature before you continue.
2. Isolate the GV pump and the other components in your process system from the electrical supply, so that they
cannot be operated accidentally.
3. If already connected, disconnect the GV inlet from your process system.
4. Ensure that the GV pump is securely bolted to the floor.
3.4 Fit an EH250/500A pump to a GV pump
Note: If your GV pump has an acoustic enclosure, the top panel(s) of the enclosure must be fitted when you fit
the EH pump.
Refer to Figure 4 and use the following procedure to fit an EH250 pump to a GV pump; where necessary, refer to the
instruction manuals supplied with the GV pump and with the EH pump.
1. Undo and remove the bolts and washers which secure the blanking plate to the inlet of the GVpump(2), then
remove the blanking-plate and the ‘O’ ring. Retain the bolts, washers and ‘O’ ring.
