5.6 Start-up<br />
WARNING<br />
Do not operate the iH system with any enclosure panels removed and do not<br />
touch any parts of the pump(s) when the iH system is on. Surfaces of the<br />
pump(s) are very hot and can cause injury to people.<br />
WARNING<br />
Ensure that it is safe to start the iH system. If you do not (and, for example,<br />
maintenance is being performed on components downstream of the iH<br />
system), you could cause injury to people.<br />
Notes:<br />
When you use the Pump Display Terminal to start up the iH system, we recommendthat you do<br />
not disconnect the Terminal from the iH system; if you do, you will not be able to use the Terminal<br />
to instantly shut down the iH system: see Section 5.5.<br />
Operation of the iH system with high inlet pressure may result in shaft-seal pressure warnings<br />
(refer to Table 6-1): the operation of the iH system will not be affected, and you can ignore these<br />
warnings.<br />
Use the following procedure to start up the iH system:<br />
1. Switch on the cooling-water supply, the nitrogen supply and the external electrical supply<br />
(if not already on).<br />
2. Ensure that the exhaust-extraction system is not blocked and that valves in the<br />
exhaust-extraction system are open.<br />
3. Ensure that the Pump Display Terminal has control of the iH system: refer to Section 5.5.<br />
4. Refer to Figure 4-1. Look at the display (2) on the Pump Display Terminal:<br />
• If there are any warnings or alarms, take the necessary corrective action (refer to Section 6);<br />
do not start the iH system.<br />
• If there are no alarms or warnings displayed, use the Switch On menu to switch on the iH<br />
system.<br />
When you switch on, the following actions will occur (with a small time delay between each<br />
action):<br />
• The LED on the On button on the Pump Display Terminal will start to flash.<br />
• The HCDP pump will be switched on.<br />
• The LED on the On button on the Pump Display Terminal will stay permanently on.<br />
