II. INSTALLATION AND COMPONENTS
Location
Place the MULTIPYCNOMETER on a level surface away from sources of heat and cold such as
radiators, air conditioning vents, direct sunlight, etc.
Mains Power
Ensure that the voltage selector at the rear of the unit matches your local mains supply. The
MULTIPYCNOMETER is designed for operation on 100V, 120V, 220V or 240V, 50/60 Hz. It was
shipped from the factory set for the voltage according to the purchase order which should match the
voltage on the serial number plate at the rear of the unit. If the selector needs to be changed refer to
the diagram below and carefully follow these steps:
1. Make sure the unit is switched OFF and unplug the power cord from its socket on the unit.
2. Pry open the plastic cover by inserting a screwdriver behind the tab on the side away from the
socket.
3. Using long-nosed pliers, gently pull out the wheel located behind the plastic cover.
4. The 4 voltages are printed on the wheel. Re-insert the wheel with the voltage required facing out,
towards you. Then close the plastic cover. Ensure that the voltage visible in the opening in the
plastic cover matches your local mains supply before reconnecting the power cord.
