Spray Head Assembly - Curtis SERA2B Service Manual

Use the screws to attach the plates to the chassis as
shown in Figure 6.2 (back view).
Connect the brew head cables to the connectors inside
the chassis. The connectors are labeled right and left to
indicate the correct cable connection.
Replace the water tower top cover and side cover.
We recommend attaching the power cord and plug to
the unit first before placing the water tower into the
cabinet beneath the counter. Make sure power to the
circuit supplying power to the unit is turned off at the
circuit breaker panel until installation is complete.
With the brew heads installed, place the water tower on
the floor of the cabinet below the counter top. Center
it between the two heads. Refer to the hole pattern
drawing (Figure 2) for the proper location of the water
tower. The water tower should be level (left to right and
front to back), on a secure surface. Wait to install the
hold down brackets until instructed to do so.
Connect the water line to the water inlet fitting at the
rear of the unit. The water flow to the machine should
be consistent. Use tubing sized sufficiently to provide a
minimum flow rate of two gallons per minute.
Brew Head Water Return Lines
Link the brew heads to the water tower by attaching
the water return lines. These are the two larger
diameter flexible silicone tubes that come from behind
the water tower. The matching return lines from the
spray head assemblies will have a straight fitting
slipped into the end of the tube. Join the return line
tubes together using this fitting. Make sure they are
correctly oriented as shown in Figures 7 and 8.
CAUTION: The water return lines must not sag.
Route them in a downhill orientation between
the bottom of the brew head assemblies and
the back of the water tower (see Figure 8). The
tubing can be shortened if necessary to make
sure that the lines are free of sag that will trap
water inside them between the brew heads and
the water tower.
Brew Head Water Supply Lines
Behind the water tower, there are two 1/4 inch
diameter water supply lines. The water supply line
tubing should be shortened to minimize length when
connected with the matching 1/4 inch tubing coming
from the bottom of the brew head assemblies. There
are straight barbed fitting connectors already inserted
into the tubes from the head unit. To make the
connection between the two tubes, insert the tube from
the back of the water tower into the supply line tube
fitting from the brew head assembly.
