6 MAINTENANCE
6.1 Safety
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.
WARNING
Hazardous chemicals 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.
•
A suitably trained and supervised technician must maintain the iH system.
•
Ensure that the maintenance 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.
•
Fit a suitable blanking plate on the iH system inlet and your vacuum system as soon as you
disconnect the iH system from your vacuum system. Do not operate the iH system unless the
inlet blanking plate is fitted or the iH system is connected to your vacuum system.
•
Fit a suitable blanking plate on the iH system exhaust and your exhaust-extraction system as
soon as you disconnect the iH system from your exhaust-extraction system. Do not operate the
iH system unless the exhaust is connected to your exhaust-extraction system.
•
Allow the pumps to cool to a safe temperature before you fit lifting bolts or start maintenance
work.
•
Vent and purge the iH system with nitrogen before you start any maintenance work.
•
Isolate the iH system and other components in the process system from the electrical supply so
that they can not be operated accidentally. Note that the emergency stop switch on the iH
system is not an electrical isolator, unless a Disconnect Box accessory is installed.
•
On an iH1000 system:
•
Wait for at least four minutes after you have switched off the electrical supply before you
touch any electrical component on the iH system.
•
Never operate the iH system (even for test purposes) unless a second protective earth
(ground) is fitted: refer to Section 3.16.3.
