Installation Of The Pump; Installation - EBARA EV-A03 Instruction Manual

P.20
The pumping performance of the dry vacuum pump is affected by the opening diameter and length of
the inlet / outlet pipe and the performance of the installed peripheral units.
Moreover, when corrosive gas is pumped, proper maintenance is required for each use to operate the
pump normally for a long period. When the pump is installed, valves and pipes are recommended to be
installed beforehand to secure higher maintenance efficiency.
Adopt pipes and sealing parts in consideration of corrosion resistance.

4.1 Installation

4.1.1 Installation
* The pump is a heavy material (Approx.23 kg). To facilitate the maintenance work, install the pump on
the floor.
* When moving pump on the uneven place, please put the pump on the carriage.
Do not step on the pump, otherwise falling or turnover may be caused. Do not place anything
on the pump as it may damage the product.
Do not lift the pump by your self. Lift the pump by hand with two (2) persons. Do not use sling
or the like to lift the pump as the handles are not designed to be used with slings.
Keep space, 100mm or more at front and rear side, 50mm or more at lateral side, to secure
good ventilation for cooling. Bad ventilation can cause pump overheat which results in
unpredicted pump failure.
Do not place the device which could be heat source at the front of pump, and consider that air
ventilation temperature around pump is kept at 15 to 30 degrees C. High-temperature ventilation
heats up pump and causes pump failure.
* Install the pump indoors.
* Install the pump inlet and inlet port facing up on a solid and level surface of the floor or frame.
* Install the pump where the base is stable enough to load and vibration.
* Allow a proper space around the pump so that the pump may be installed and maintained smoothly.
* Be careful to make the temperature from 15 to 30 deg. C and to make the humidity from 20 to 80%
(condensation must not exist) around the pump while it is operating, especially in closed place,
because that may cause dew condensation inside the pump.
* Keep space, 100mm or more at front and rear side, 50mm or more at lateral side, to secure good
ventilation for cooling.
* Set the pump up in the place of above sea level 2000m or less.
* Please use by "Pollution degree 2".
Avoid installing the pump in the following places:
a) Outdoors, a place that may be splashed with water, and a place of extremely high humidity. (A place
of 80% or higher humidity is not proper.)
b) A place where a toxic gas such as acid and alkali gases exists.
c) A place where an explosive or combustible gas exists.
d) A dusty place.
* Do not install the pump in the environment where the pump may be exposed to rain, snow, ice and
dust.
