Lubrication; Connect The Dry Pumping System To Your Vacuum/Exhaust System - Edwards iH80 Instruction Manual

If you want to secure the iH in place to prevent inadvertent movement (for example, during an earthquake), take
note of the following:
The iH system seismic brackets
floor installation.
The iH system can be secured to the floor by fitting suitable bolts or studs (not supplied) through the
17.5 mm hole in the seismic brackets.
If vibration transmission to the floor is a concern, suitable vibration isolators (not supplied) should be fitted
between the seismic brackets and the bolt or stud.
Although the iH system is supplied with four seismic brackets, two brackets are capable of protecting the
system during an earthquake. The system can therefore be secured as shown in
reduce the effective system footprint if required.
If all four seismic brackets are to be used, ensure that the bolt spacing is adequate for the floor strength and loads
anticipated.
3.2

Lubrication

Ensure that the oil-levels in the HCDP pump and the HMB pump are correct. If a pump oil-level is incorrect, pump
performance may be affected and the pump may be damaged.
The iH system is given a charge of oil before it leaves the factory. There is no requirement to adjust the oil level.
3.3 Connect the dry pumping system to your vacuum/exhaust
system
Pipe the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases or
vapours to the surrounding atmosphere.
Do not operate the system with the exhaust pipeline blocked. If the exhaust pipeline is blocked,
the system can generate exhaust pipeline pressures of up to 7 bar (7 x 10
Use a catchpot to prevent the drainage of condensate back into the iH system. Condensate that drains back into
the iH could damage the HCDP pump.
Do not reuse any O-ring or O-ring assembly and do not allow debris to get into the iH system during installation.
When you connect your iH system to your vacuum system, take note of the following:
To get the best pumping speed, ensure that the pipeline which connects the vacuum system to the iH system
is the minimum length possible and has an internal diameter not less than the iH system inlet-port.
Ensure that all components in the vacuum pipeline have a maximum pressure rating which is greater than the
highest pressure that can be generated in your system.
