Setup and Installation
This silicon seat cup is a replacement part and requires installation into an existing BUNN faucet assembly. Installation hardware is typically included with the original faucet or appliance, but this product specifically provides the silicon seat cups.
Tools Required (Not Included):

Installation Steps:
- Disconnect Power: Ensure the coffee or tea brewer is unplugged from the power outlet and has completely cooled down.
- Drain Appliance: If applicable, drain any remaining liquid from the appliance.
- Access Faucet Assembly: Carefully disassemble the faucet to access the internal components. This may involve unscrewing the faucet handle or spout. Refer to your specific BUNN appliance's manual for detailed disassembly instructions.
- Remove Old Seat Cup: Locate the old silicon seat cup. It may be worn, cracked, or hardened. Carefully remove it.
- Clean Area: Clean the area where the new seat cup will be installed, ensuring no debris or mineral buildup is present.

Operating Instructions
The BUNN 02766.0000 Silicon Seat Cup is an internal component and does not have direct operating instructions. Its function is to enable the proper operation of the faucet by preventing leaks. Once installed, the faucet should operate as intended, providing a drip-free dispense of beverages.
