3. The bottom casters are only suitable for short distance movement. For long distance
movement, use a handling device (such as Fig. 3-2 Forklift handling) so as to avoid
damage to the casters.

y Cabinet fasteners
If DELTA cabinet (Model number MSR1110, MSR2110) is used as the adjacent cabinet, it
can be fastened by connecting fasteners. Each cooling unit is provided with four connecting
fasteners (two at the front and two at the rear). You must remove the front and back doors

3 Use the key to unlock the rear door, remove the earth wire, raise the door, and take it
out. The rear door is of the split type and, if necessary, take down both doors.
NOTE: Put the front and rear doors that have been removed in a safe place so
as to avoid any equipment damage or personal injury due to collisions.
4 Use a screwdriver to loosen the screw below the fastener and lock it on the adjacent
