1.4. Installation
Upon receiving the Ohaus Hotplate-Stirrer / Hotplate / Stirrer check to ensure that no damage has occurred during
shipment. It is important that any damage that occurred in transport is detected at the time of unpacking. If you do
find such damage, the carrier must be notified immediately.
After unpacking, place the Hotplate-Stirrer / Hotplate / Stirrer on a level bench or table, away from explosive
vapors. Ensure that the surface on which the unit is placed will withstand typical heat produced by the unit and
place the unit a minimum of six (6) inches from vertical surfaces. Do not position the equipment such that it is
difficult to disconnect the power cord during use. Always place the unit on a sturdy work surface.
The Hotplate-Stirrer / Hotplate / Stirrer is supplied with a 3 conductor, grounded power cord that should be plugged
into a matching standard grounded outlet. If the cord supplied does not meet your needs, please use an approved
power cord that has ratings equal or exceeding those of the originally provided cord and that complies with the
local/national regulations of the country in which the equipment is to be used. Replacement of the plug must be
made by a qualified electrician.
