Clean-In-Place Operating Instructions
When there is a noticeable drop in the Flo-Rite-
Temp's — hot water capacity, temperature, or an increased
water pressure drop across the unit — tube bundle scale
removal should be considered using the commercially
available product called RITE-Qwik*.
Tube bundle scale removal can be accomplished as
follows:
Step 1 - Shut off steam supply valve #1 to the Flo-Rite-
Temp.
Step 2 - While the water pressure is still ON and the steam is
OFF, run the Flo-Rite-Temp for (10) ten minutes or until the
outside of the unit is cool to the touch.
Step 3 - Shut the water inlet valve #4 OFF and water outlet
valve #5 OFF; open cleaning connection outlet #7. Connect
air hose with regulator to valve #9. Turn air on slowly to
approximately 5 psi. Increase to maximum of 25 psi. Leave
air pressure on until water stops coming out of connection
#7. Turn air (valve #9) off. Open cleaning connection inlet #8
and remove the pop-off valve or inlet pipe plug #6 from the
lower diaphragm cover of the control valve . Let the
remaining water drain by gravity from the Flo-Rite-Temp.
Step 4 - After all the water has been drained, reinstall the
pop-off valve or pipe plug #6 into the lower diaphragm cover
of the control valve.
Step 5 - With hose valve closed connect return hose A of the
Clean-in-Place to the outlet cleaning connection #7 of the
Flo-Rite-Temp.
Step 6 - With hose valve closed connect discharge hose B of
the Clean-in-Place to the inlet cleaning connection #8 of the
Flo-Rite-Temp.
Step 7 - Start pump. Open ball valve of discharge hose B of
the Clean-in-Place.
Step 8 - Slowly open the ball valve on return hose A and
watch for foaming in the tank.
Step 9 - Clean-in-Place is now circulating cleaning solution
through the Flo-Rite-Temp. Periodically check the solution
to see if it has changed color or quit fizzing. If the cleaning
Flo-Rite-Temp
* RITE-QWIK is a non hazardous chemical cleaner which has
been proven effective for removing deposits without
harming the FLO-RITE-TEMP internally.

solution has stopped fizzing and has not changed color, the
Flo-Rite-Temp is clean. You may save the remaining unspent
solution for your next job. If the solution quits fizzing and the
color has changed, add new cleaning solution. Continue
circulating in the same manner as above. Do not exceed a
maximum circulation time of (3) three hours.
Step 10 - Shut-off pump. Close discharge hose valve B on
Clean-in-Place. Open air (valve #9). Turn air on slowly to
approximately 5 psi. Increase as Clean-in-Place fluid returns
to tank. (Maximum air pressure 25 psi.)
Step 11 - Leave air blow for approximately 3-5 minutes. This
should return most of the fluid to the tank. Close both hose
valves.
Step 12 - Disconnect return hose A from the Flo-Rite-Temp
outlet cleaning connection #7 and discharge hose B from the
inlet cleaning connection #8. Also remove the pop-off valve
or pipe plug #6 from the lower diaphragm cover of the
control valve. Let the cleaning solution drain by gravity from
the Flo-Rite-Temp.
Step 13 - Close valve #2 going into the system and open
valve #3 going to the drain.
Step 14 - Open the water outlet valve #5 then open SLOWLY
inlet water valve #4. Let the water run for (1) one minute
before installing the pop-off valve or pipe plug #6 into the
lower diaphragm cover of the control valve.
Step 15 - After the pop-off valve or pipe plug #6 is installed,
run water into the drain for (5) five minutes to flush out all of
the cleaning solution. Throttle the outlet valve #3 open and
closed to purge the air from under the diaphragm.
Step 16 - After flushing the unit, close valve #3 and open the
steam supply valve #1 SLOWLY and let the Flo-Rite-Temp
heat up.
Step 17 - Set the Flo-Rite-Temp as needed. (This step may
not be necessary).
Step 18 - Open valve #2 to the system and monitor the
system until the temperature is back to normal.
Step 19 - After use, flush the pump with water to remove the
chemical to prevent seal deterioration.
