The unit comes with four casters for easy mobility. To install:
- Carefully tilt the unit to access the bottom. It is recommended to have assistance to prevent damage or injury.
- Screw the casters into the designated holes at each corner of the base. Ensure they are securely tightened.
- Return the unit to an upright position.
2.3 Door Reversal (Optional)
The door hinge is reversible. Refer to the detailed diagram in the included printed manual for specific steps on how to reverse the door swing direction.
2.4 Internal Configuration: Kegerator vs. Refrigerator Mode
The HCK K90 can be configured for keg dispensing or as a standard beverage refrigerator.
- For Kegerator Mode: Remove the internal wire shelves to accommodate a 1/6 barrel or Cornelius keg.
- For Refrigerator Mode: Install the three wire shelves to maximize storage for cans and bottles.
