CAUTION
All maintenance and/or repairs must be performed by a journeyman refrigeration mechanic or air-conditioning technician.

When moving the unit, it should be kept in its normal installed position. If the unit is not kept level and vertical, damage to the

Equipment may contain components subject to electrostatic discharge (ESD). Before attempting to mount or service these
electronic devices, make sure you have no charge built up by touching a ground source. When possible, use a wrist-grounding
strap when working on or near electronic devices.
