6 Before use

6.1 Setting up the pump
Stand the pump on a dry, horizontal surface
and secure it to prevent possible movement.
Check to ensure an unobstructed flow of cool-
ing air to the pump.
The area up to at least 20 cm from the cooling
air intake and exit must be kept free.
WARNING
Avoid pinching or kinking the supply cord and
hose.
NOTE
Check the water level in the water separator
and empty it if necessary.
Connect the hose from the pump to the vacuum
baseplate.
6.2 Connecting to a grounded power
outlet
Grounding instructions
This product must be grounded. In the event
of an electrical short circuit, grounding reduces
the risk of electric shock by providing an es-
cape wire for the electric current. This product
is equipped with a cord having a grounding
wire with an appropriate grounding plug. The
plug must be plugged into an outlet that is
properly installed and grounded in accordance
with all local codes and ordinances.
WARNING
Improper installation of the grounding plug is
able to result in a risk of electric shock. When
repair or replacement of the cord or plug is
required, do not connect the grounding wire to
either flat blade terminal. The wire with insula-
tion having an outer surface that is green with
or without yellow stripes is the grounding wire.
Check with a qualified electrician or service-
man when the grounding instructions are not
completely understood, or when in doubt as to
whether the product is properly grounded. Do
not modify the plug provided; if it does not fit
the outlet, have the proper outlet installed by a
qualified electrician.
This product is for use on a nominal 120-V
circuit and has a grounding plug. Only connect
the product to an outlet having the same con-
figuration as the plug. Do not use an adapter
with this product.

6.3 Extension cords

Use only a 3-wire extension cord that has a 3-
blade grounding plug, and a 3-slot receptacle
that accepts the plug on the product. Make
sure your extension cord is not damaged. When
using an extension cord, be sure to use one
heavy enough to carry the current your product
draws. For lengths less than 100 ft, 16 AWG
extension cords shall be used. An undersized
cord results in a drop in line voltage and loss
of power and overheating.
