2-2 Midi 40 CO2 Incubator
• Caution Be careful when handling access panels, parts, or any
components which may have sharp edges which may cause damage to
wiring and electrical connections, or personnel injury.
Caution Warranty will not be responsible for damage caused by failure
•
to disconnect the unit from all power sources before cleaning,
troubleshooting, or performing other maintenance on the product or
its controls. To disconnect power supply to the incubator, unplug the
supply cord at the back of the incubator. Note that turning the key
switch on the front control panel to the Off position is not sufficient to
disconnect power.
• Caution Do not modify system components, especially the controller.
Use OEM exact replacement equipment or parts.
Before use, confirm that the product has not been altered in any way.
• Caution Use only approved replacement parts that are the correct size,
rating, and capacity as the original part.
• Caution Never interfere with or bypass the operation of any switch,
component or feature of the unit.
• Caution Before reconnecting the power supply, ensure all uninsulated
wires or terminals are not touching the cabinet
Caution Warranty will not be responsible for damage caused by altering
•
a power cord in order to make it fit an electrical outlet. The line cord
must be plugged into a grounded, three-prong receptacle. Never cut or
remove the third (ground) prong from the power cord connector.
• Caution Never substitute ordinary wire for any internal wiring. The
internal wiring of these units carry a special rating due to the somewhat
high currents that they can be subjected to at times. This heavy current
load generates heat, which can melt ordinary wire. It is vitally
important that all connections are tight and secure.
• Caution To avoid electrical shock, fire, and equipment damage, ensure
that any wires or terminals touching the cabinet are insulated before
connecting the power supply. Electrical wiring and all grounds must be
correctly reconnected and secured away from sharp edges, components
and moving parts. All panels and covers should be reinstalled before the
incubator is plugged in.
