7. Maintenance

WARNING: HAZARDOUS VOLTAGE
Risk of electric shock. Only personnel specially trained to perform electrical
maintenance should attempt troubleshooting in electrical enclosures. These
enclosures contain hazardous voltages and are not operator areas. Wait for a
minimum of four minutes after switching off the electrical supply before touching any
electrical component on the system.
WARNING: SYSTEM LEAKAGE
Risk of injury or damage to the equipment. Do a leak test of the system after
maintenance. If leaks are found, seal them to prevent dangerous substances leaking
out of the system or air getting in to the system.
CAUTION: ABRASIVE CLEANING MATERIALS
Risk of damage to equipment. Do not use cleaning materials based on strong alkalis,
aggressive or chlorinated solvents. Do not use cleaning materials containing
abrasives.
WARNING: LOCKOUT AND TAGOUT
Risk of injury or death. Electricity, nitrogen and water supplies are possible hazardous
energy sources. Lockout and tagout sources before you do the maintenance to the
pump.
WARNING: HOT SURFACES
Risk of burns. Do not touch the pump exhaust or check valve while the pump is in
operation since the temperatures of these parts can be high. These parts can be hot
even after the system has stopped.
WARNING: USE PROTECTIVE EQUIPMENT
Risk of injury or death. Personal protective equipment should be checked and used as
specified by its supplier. Hazardous chemicals that have been pumped are present in
the pumps and piping. Use of correct protective gloves and clothing along with a
respirator is recommended if contact with hazardous substances is possible. Be
cautious when you work with fluorinated materials which can possibly have been
exposed to temperatures greater than 260 °C. Refer to our safety data sheets for
more information.
The system is given a charge of oil before it leaves the factory. It is not necessary to
check or adjust oil levels between major overhauls.
1. We recommend you do a monthly visual inspection of the system. Check that the
cables, hoses and pipelines connected to the pump are in good condition and
make sure that all connections are secure.
