2.50 INTAKE AND DISCHARGE PROVISION
2.51
The vacuum regulator and vacuum dial gauge is attached to the bracket. The vacuum regulator
allows the vacuum level to be set between roughly atmospheric pressure and the maximum vacuum
allowed for the pump model. The regulator allows discharge pressure to be set between atmospheric and
the maximum possible for the pump model. Model 79202 is equipped with a pressure port.
Note: Adjusting the vacuum regulators will affect the performance of the pump.

Power Source Review
Review the power source and the motor rating to be sure they agree in voltage, phase, and frequency.
Serious damage may occur to the motor if it is connected to an improper voltage.

Servicing of Double-Insulated Product
In a double-insulated product, two systems of insulation are provided instead of grounding.
No grounding means is provided on a double-insulated product, nor should a means for grounding
to be added to the product. Servicing of a double-insulated product requires extreme care and knowledge
of the system and should be done only by qualified service personnel. Replacement parts for the
double-insulated product must be identical to those parts in the product.

Overload Protection
This station has a single use (fuse) type of overload protector. If the motor should overheat, the
protector will shut the unit off. If this should occur, unplug the station and contact the service center.

2.70 VACUUM CONNECTIONS
2.71
For best results, Cole-Parmer recommends the length of the tubing between the pump and the chamber
be kept as small as possible.

Air Admiral
Vacuum/Pressure Station Models 79202-30 & 79202-35 come with dial vacuum gauges.
®
The vacuum gauge gives negative pressure - That is pressure below atmospheric.
The reference point for the gauge is atmospheric pressure.
Please keep in mind that atmospheric pressure tends to vary from day to day. As a result of this
variability, the dial vacuum gauge will indicate slightly different maximum vacuum readings
from day to day.
