SWAP Valve Instructions

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 diagrams on page 2. 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. Selecter 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.
