phase, 60 Hz.
Model 35 requires 3-
wire, grounded service
rated 120/208 or 120/240

Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1.
An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
3. Place the heater switch at the rear of the brewer in the “OFF” lower position.
4. Remove the front panel beneath the sprayhead.
5. Feed the cord through the strain relief and connect it to the terminal block.
6. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding.
Replace the front panel.
7. If plumbing is to be hooked-up later be sure the brewer is disconnected from the power source. If plumbing
has been hooked-up, the brewer is ready for Initial Set-Up.
PLUMBING REQUIREMENTS
Models CW-APS & CWT-TS:
These models are completely portable and require no attached plumbing.
Models CWT-APS, CWTF-APS, CWT-TS, CWTF-TS:
These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi from
a 1/2" or larger supply line. A shut-off valve should be installed in the line before the brewer. Install a regulator
in the line when pressure is greater than 90 psi to reduce it to 50 psi. The water inlet fitting is 1/4" flare.
NOTE - Bunn-O-Matic recommends 1/4" copper tubing for installations of less than 25 feet and 3/8" for more than
25 feet from the 1/2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer
to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. The
size and shape of the hole made in the supply line by this type of device may restrict water flow.
This equipment must be installed to comply with the Basic Plumbing Code of the
Building Officials and Code Administrators International, Inc. (BOCA)
and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).
