TUBING CONNECTIONS

CONTROL TUBING CONNECTIONS
C.O.M. Models Converted to Hydraulic Configuration
In hydraulic installations, the flange compartment should be used to make the Control Tubing
connections to the rotor. This allows for tubing connections, pressure tests and flushing of the
control lines - all without digging.
Converting C.O.M. models to the Hydraulic configuration
– Remove the two stainless steel
screws and lift the flange compartment lid to expose the flange compartment. Find the end of the
⅛ inch tubing that comes into the flange compartment from the bottom of the rotor (FIGURE 4).
Check-O-Matic (“C”) versions of TTS rotors can be converted for use in Normally Open Hydraulic
systems by removing the end cap on the ⅛ inch tubing. To do so, slide the ¼ inch tube retainer
towards the end of the tube (FIGURE 5). Then, pull to remove the end cap with attached ¼ inch
tube retainer from the brass connector fitting (FIGURE 6).
To connect the ¼ inch control tube from the controller to the TTS rotor tubing, insert ¼ inch tubing
from controller into the bottom of the flange compartment. Next, slide the ¼ inch tube retainer
(from end cap supplied with rotor) onto the ¼ inch Control Tubing. Then connect the ¼ inch
Control Tubing to the rotor’s ⅛ inch Control Tubing by pressing together at the brass fitting.
Finally, slide the ¼ inch tube retainer towards the brass fitting to lock the tube in place.

UPPER SNAP-RING REMOVAL –
G800 SERIES
Hold Snap-ring Tool vertical over the rotor’s
upper snap ring. Align the metal end of the
snap-ring tool to the indicator on the snap-ring’s
rubberized wiper seal (FIGURE 7). Use the palm
of the other hand to drive the tool downward &
through the rubberized membrane. Tool should
penetrate about ½ inch into the snap-ring
assembly (FIGURE 8). While holding the tool
within the snap-ring, press the tool’s handle
downward and away from the center of the rotor.
As the tool is pressed downward, the snap-ring
will lift from the rotor (FIGURE 9). While using
the tool to hold the snap-ring in this elevated
position, use the other hand to pull the snap-
ring from the rotor. If the snap-ring’s rubberized
wiper seal appears to be the only part that is
lifting, the tool has not penetrated into the
snap-ring far enough.
