Valve and Actuator Replacement
Should for any reason the control valves need replacing
follow this procedure .
Note the orientation and rotation of the valve bodies are
not the same . Failure to install the valves and actuators
properly will result in loss of functionality . When servicing
the unit be sure to disconnect power to the unit .
Hot Water Actuator Replacement
The hot water valve is a one way mixing valve with a
Belimo actuator . When replacing the actuator be sure
to disconnect power to the unit . Next remove wiring
from terminals .
Be sure to note location and color of
conductors.
Remove the phillips screw in the center of the actuator
knob (
See Figure 12
) .
Remove old actuator .
As shown in
Figure 13
the dial is horizontal indicating a
zero flow position . The 0-10 Volt signal for this orientation
is 0 volts .
NOTE:
The orientation of the notches on the center
post at 9:00, 6:00 and 3:00 o’clock . This is the proper
orientation of the valve to the actuator at a 0 volt signal .
Again this only applies to the hot water 1-way valve . The
valve must be oriented in this position when replacing to
assure proper operation .
In operation the hot water valve rotates from the 0 volts
position shown in
Figure 12
, clockwise 90º . By pushing in
on the black knob the valve/actuator should move in this
manner . If not the actuator is misaligned . To realign the
actuator to the correct orientation remove the actuator
from the valve . Pushing in on the knob, rotate the knob
as far counter-clockwise as it will go . Now completely
pull out the knob and re-insert it oriented as shown in
Figure 12
. Reinstall onto the valve with the valve core in
the position shown in
Figure 13
.
