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

Tipping danger: Keep the shipping support brackets attached to the front and rear of the cabinet after removing the Cold Row

Position someone on each side of the cabinet to stop it from tipping over if the shipping brackets must be removed before
installing the server racks on each side.
