STARTUP
Unpacking
1. Carefully remove crate from the skid.
2. Remove machine from skid.
3. Wipe down outside of the machine.
Power Requirements
The owner must supply the correct single phase power source in accordance with the
National Electric Code. The machine is rated at 110 volt, 60 Hz, 15 amps; or 220 volt, 50
Hz, 8 amp. Do not use an extension cord to connect the machine to the wall outlet.
Grounding Instructions
The Ultravac
®
250 must be grounded. In the event of malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce the risk of electric shock.
The unit is equipped with a equipment-grounding conductor cord and a grounding plug.
The plug must be plugged into an appropriate outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
DANGER
Hazardous voltage.
Improper connection of the equipment-grounding conductor can result in a risk of electric
shock.
The equipment-grounding conductor outer surface is green with or without yellow
stripes. If repair or replacement of the cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal. Check with a qualified electrician or
Koch Equipment Services Inc. technician if the grounding instructions are not completely
understood, or if there is doubt as to whether the unit is properly grounded. Do not modify
the plug provided with the unit – if it will not fit the outlet; have a proper outlet installed by
a qualified electrician.
For 110 Volt Units
This unit is for use on a nominal 110V circuit, and has a factory equipped grounding plug
(see Figure 2.2A on page 2.2). A temporary adaptor (see Figure 2.2C on page 2.2), may
be used to connect this plug to a two-pole receptacle (see Figure 2.2C on page 2.2) if a
properly grounded outlet is not available. The temporary adaptor should be used only until
a properly grounded outlet (see Figure 2.2B on page 2.2) can be installed by a qualified
electrician. The green rigid ear extending from the adaptor must be held in place by the
metal screw on a properly grounded outlet box cover.
