Maintenance
A590-00-880 Issue D
CAUTION
Drain the cooling-water from the iH system, if you will transport or store it in conditions where the cooling-water
could freeze. If you do not, cooling-water may freeze in the iH system and damage the pump(s) and/or the
cooling-water pipelines.
If you want to remove the iH system from its operating location and move it to another location where you will do
maintenance, use the following procedure:
1. Purge the iH system and shut down the iH system as described in
Section 4
and allow the iH system to cool down.
2. Isolate the power by disconnecting the mating-half from the electrical supply connector, then isolate the water
and the gas purge supply.
3. Switch off your nitrogen and cooling water supplies. Disconnect the nitrogen supply, taking care as any trapped
gas under pressure is released. Disconnect the cooling-water supply followed by the cooling-water return.
4. Disconnect the inlet and outlet from the vacuum and exhaust systems and fit blanking caps.
5. If necessary, disconnect the iH air-extraction port from your factory extraction system.
6. If necessary disconnect any accessories from the iH system.
7. Adjust the levelling feet so that the iH system rests on the castors.
8. Move the iH system to the location where you will do maintenance.
After maintenance is complete, re-install the iH system as described in
Section 3
.
