Section 1 - Installation and Start-Up
1.1 Unloading and Moving the Freezer
To remove the freezer from the pallet, use the 7/16” wrench to remove all the bolts
securing the shipping bracket to the pallet. Remove the shipping bracket. Remove the ramp
boards from the pallet and place the slotted end over the ramp brackets on the pallet. The support
blocks on the ramps will be facing down. Before moving the freezer, make sure the casters are
unlocked and moving freely. Align the caster with the ramp boards. Use adequate personnel to
roll the freezer off the pallet.
If tipped more than 45°, allow the unit to set upright for
24 hours before start up.
The freezer can be easily pushed to the desired approved location that is described in
Section 1.5. When the freezer is in position, set the front caster brakes.
The freezer must not be moved with the product load inside.
