2.4 ENVIRONMENT EQUIREMENTS
The machine will be difficult to start if the air temperature is very low. This is caused by the
increase in the vacuum pump’s oil viscosity due to the low temperature. To prevent this, please set
up machine according to the installation checklist described as below:
z
Temperature: around 5 ~ 40
℃
z
Working elevation: between 0 ~ 1000 meters
z
Relative humidity: 30 ~ 95% RH
z
During operating, heat is generated by the vacuum pump and vacuum process, so a
machine temperature of around 70 ~ 80
℃
is normal. The machine must have free air
access for cooling.
z
A minimum distance from walls, other machines, etc. should be maintained, at least 20 cm for
each side of machine for providing adequate ventilation.
