Fetco MBS-1221 Users Manual And Operator Instructions page 15

General:
1. If not installed correctly by qualified personnel, the brewer will not operate properly, and damage may result.
2. Utilize only qualified beverage equipment service technicians for service and installation.
3. Always have an empty dispenser under spray head of all coffee brewing equipment-including when at idle
4. Damages resulting from improper installation are not covered by the warranty and will void the warranty.
Below are the key points to consider before installation:
Electrical:
1. All CBS_Series brewers require an electrical ground wire. Installation without grounding is dangerous.
2. Note Equipotentiality Terminal, if present,
of equipment or of a system to the same potential, not necessarily being the earth (ground) potential, e.g. for local bonding.)
3. Verify voltages, polarity, circuits, and circuit breaker access before attaching equipment.
4. Brewers in this series wire differently in regard to a neutral wire. Review the wire diagrams.
5. The electrical diagram is located in the User's Guide and online at www.fetco.com.
6. Make sure of the tight grounding of the equipment and use the external ground bolt.
7. The installation must comply with applicable federal, state, and local codes having jurisdiction at your location.
Cheossible
1. All beverage equipment must use a water filter. A finishing carbon filter is preferred
2. Install the filter unit after a water shutoff valve and in a position to facilitate filter replacement.
3. The water line and newly installed filter cartridge must be flushed thoroughly prior to connecting it to the brewer to
prevent debris from contaminating the machine
4. Verify that the water line will provide a flow rate of at least 1½gpm/(5.7lpm) per minute and the water pressure is
between 20-75 psig (138-517kPa) before making any connections. MBS-1221 is factory calibrated to a stable,
non-fluctuating water supply pressure at 45 psi
5. Only use the supplied factory fitting to attach water supply line to both brewer (shipped in brew basket)
6. The supplied fitting is a 1/4" male flare fitting for 1/4" supply line. Other adaptors may be substituted.
7. Hand tighten the factory fitting when connecting the stub on the brewer. This will reduce stress on the internal
connections and reduce the possibility of leaks developing after the install has been completed
Tank Drain
The water tank must be drained before maintenance procedures, and when the unit is to be relocated or shipped.
Drain is for service use only and must not be permanently connected. NOTE: Never plumb a water line to the drain.
utility connections to the brewer are broken.
1. Move the unit near a sink or obtain a container large enough to hold four gallons of water.
Note: The hot water tank may hold up to 2¾ gallons.
2. Remove the front panel and tank cover and allow the tank to cool to a safe temperature
3. The tank drain line and clamp are located inside-under the hot water tank. Pinch the drain line clamp to close
4. Locate the fill valve against the back wall, using pliers, loosen the hose clamp and move it back over the tube.
Note Do not loosen the hose clamp to the bottom of the hot water tank
5. Crimp the tube an inch or two away from the drain plug to prevent water from flowing and pull it off the valve.
6. Pull the tube end out of the brewer and position over sink or bucket.
7. Release the crimped tube and hose clamp and allow the water to flow into the sink or container.
8. Reverse steps 4-8 when service is complete. Ensure pinch clamp is open and hose clamps are in place.
