5-8. REPLACEMENT OF THE UPPER AND/OR LOWER WATER MANIFOLDS
A. Drain the reservoir as described in Section (4-2.4.).
B. Remove the rear enclosure panel as described in Section (5-1.1.).
C. Locate the copper water manifold to be replaced. The two manifolds, one lower and one
upper, are wrapped in black foam and are secured to the left side (viewed from the rear)
of the unit as shown in Figure (5-1.). The lower manifold is connected to the male quick-
disconnect fittings and to the hose from the pump. The water temperature sensor is
inserted in the end of the lower manifold. The by-pass at the other end of the lower
manifold connects to the water reservoir. The upper manifold is connected to the female
quick-disconnect fittings and the hose to the water flow indicator. To replace the lower
manifold, continue to Step E. To replace the upper manifold, go to Step R.
D. Remove the water temperature sensor as described in Section (5-7.), Steps D - F. Set
to one side.
E. Disconnect the hose at the copper elbow of the lower manifold by loosening the screw
clamp. Be sure to exercise caution there may be water in the line.
F. Using a 9/16" open end wrench, unscrew and remove the three male quick-disconnect
fittings from the outside of the unit.
G. Disconnect the by-pass line from the reservoir. Remove the clamp from the clear plastic
by-pass line and disconnect the bypass line.
H. Carefully work the lower manifold from the holes on the side of the unit and withdraw it
from the back of the unit.
I. Insert the replacement lower manifold so that the three outlets align with the three holes
on the side of the unit, the outlet for the water temperature sensor points to the back of
the unit, the copper elbow points toward the front of the unit and the clear plastic bypass
line runs from the front of the unit toward the reservoir. Appropriately apply Teflon tape
to all threaded connections.
J. Reconnect the three male quick-disconnect fittings on the bottom row starting with the
fitting farthest from the water flow indicator. Check that the fittings are tight.
K. Connect the hose from the pump housing to the copper elbow of the manifold and
tighten the clamp.
L. Remove the used white Teflon tape from around the threads of the water temperature
sensor. Apply new Teflon tape.
M. Reinsert the water temperature sensor.
N. Insert the bypass tubing into the copper tube from the reservoir.
O. Secure the clear plastic tube with the plastic "snapper" clamp.
