CW Series Models Overview: CT, CTF, CWT, CWTA, CWTB, CWF
The Bunn CW Series encompasses a range of still and sparkling water dispensers designed for commercial use․ Models include the CT, CTF, CWT, CWTA, CWTB, and single CWF, each offering unique features to suit diverse needs․
CT models are available in both Push Button (PB) and Portion Control (PC) configurations, offering flexibility in dispensing options․ The CTF and CWT variants provide specific functionalities, while CWTA and CWTB cater to specialized applications․
These brewers require a cold water system operating between 20 and 90 psi, utilizing a 12-inch or larger supply line․ Bunn Refresh models, like the CT PC, are available in black or white finishes․
Installation and Setup
Proper installation is crucial for optimal performance․ Ensure a cold water connection with 20-90 psi pressure, utilizing a shut-off valve and regulator if needed․
Water Supply Requirements: Pressure and Line Size
The Bunn CW Series brewers necessitate a dependable cold water supply for consistent operation․ Specifically, these models – encompassing CT, CTF, CWT, CWTA, CWTB, and single CWF configurations – require operating water pressure to fall within the range of 20 to 90 psi (138 to 620 kPa)․
Furthermore, the supply line connecting to the brewer must be at least 1/2 inch (12mm) in diameter to ensure adequate water flow․ If your water system exceeds 90 psi, it is imperative to install a pressure regulator to reduce the pressure to a maximum of 50 psi (345 kPa)․
Failure to adhere to these specifications may compromise the brewer’s performance and potentially void the warranty․ Bunn-O-Matic strongly recommends professional installation to guarantee compliance with local plumbing codes and optimal functionality․
Installing a Shut-Off Valve
A dedicated shut-off valve is a crucial component of the Bunn CW Series installation, providing a convenient and essential means to isolate the brewer from the water supply․ This valve facilitates routine maintenance, repairs, and emergency situations without requiring a complete system shutdown․
The shut-off valve must be installed on the cold water line before the connection to the brewer․ Ensure the valve is readily accessible for easy operation․ A full-port ball valve is recommended for minimal flow restriction․
Proper installation prevents water damage and allows for safe servicing․ Bunn-O-Matic emphasizes the importance of a qualified plumber performing this installation to guarantee adherence to local plumbing regulations and a secure, leak-free connection․
Water Pressure Regulation (Above 90 psi)
Maintaining appropriate water pressure is vital for the optimal performance and longevity of your Bunn CW Series brewer․ If the incoming water pressure exceeds 90 psi (620 kPa), a pressure regulator must be installed on the supply line before the brewer connection․
Bunn-O-Matic recommends reducing the pressure to a maximum of 50 psi (345 kPa) using a suitable regulator․ Excessive pressure can damage internal components, leading to malfunctions and voiding the warranty․
Regularly inspect the regulator for proper function and ensure it’s correctly adjusted․ Proper regulation safeguards the brewer and ensures consistent beverage quality․
Connecting to the Cold Water System
Ensure the Bunn CW Series brewer is connected to a dedicated cold water supply line․ This line should be at least 1/2 inch (12mm) in diameter to provide adequate water flow․ Before connecting, verify the water supply is potable and meets local health regulations․
After installing the shut-off valve and, if necessary, the pressure regulator, carefully connect the water line to the brewer’s inlet fitting․ Hand-tighten the connection, then use a wrench to gently tighten another quarter turn․
Inspect for leaks immediately after connection and during initial operation․
