Using a Smartflow Mold Temperature Regulator
(MTR)
1. Stop the press.
2. Note the setting on the calibration scale, then move the knob to the “Flush” position (Clockwise to
the stop).
3. Perform the SWAP Purge Procedure (see OPERATION above).
4. On the MTR, return the knob on the calibration scale to the previous position. (It will be necessary to
rotate the knob more than one complete turn counterclockwise.)
5. Select Water after the new mold is installed and the cooling water connections are secure.
Using a TCU
(temperature control unit in a closed loop system)
We recommend using a temporary bypass hose or TACO Air Separator per figures 2 & 3. Install bypass
hose and open ball valves on each end of the bypass before purging the mold (figure 3). An air
separator may be installed in the location shown at the highest point possible (figure 2).Your
installation may vary.
1. Stop the press.
2. Check the TCU manufacturer’s instruction for Purge position or Bypass instructions.
3. Perform the SWAP Purge Procedure (see OPERATION above).
4. Reset the TCU to the original operating configuration.
5. Select Water after the new mold is installed and the cooling water connections are secure.
Note: It is possible for the majority of the purge air to rush through the unrestricted water
passages, leaving some water in bubblers or baffles. After unrestricted mold passages have been
purged, close valves on these passages so more air is available to purge the restricted water
passages. It may be necessary to purge longer or to purge restricted passages individually to
completely evacuate the water.
Caution: confirm that the SWAP valve is selected to VENT and that the manual vent button has
been pressed to relieve trapped air pressure or residual water before disconnecting any water
lines. A drain tube can be connected to the Manual Vent-Drain and run to a suitable drain.
