3.2. Checking Tie Bar Torque
The nuts on the threaded tie bars can loosen during shipment, and if
not retightened the pressure from the incoming water can cause
permanent damage. Therefore, the tie bar nut torque must be
checked and the module tightened as required after any
transport and before flowing water into the module. Refer to Figure 3-1 and re-torque
as required. Not all modules will require retightening but all should be checked.
Always drain water from the LX module before tightening the endplate tie bar nuts. This
relieves pressure in the module. Failure to do so can result in irreversible damage.
Do not open the LX Module. Opening the module will void the warranty and do irreversible
damage.
3.2.1. Tightening End Plate Tie-bar Nuts
Figure 3-2 shows the sequence in which to re-
torque the tie bars. Start the torqueing process
with #1, and finish with #14. Use the following
procedure:
· Use a 19 mm open ended wrench to hold the
acorn nuts on the plumbing (cathode) end of
the module.
· Set the torque wrench to 15 ft-lbs (20 N-m).
Using a 19 mm extra deep socket (such as
IONPURE part number W2T210908 ▼) on the
torque wrench, turn all 14 tie-bar
brass hex nuts (anode end) to 15
ft-lbs (20 N-m) following the
sequence in Figure 3-2.
· Reset the torque wrench to 25 ft-lbs (34 N-m)
and repeat the sequence as required until all tie
bars are at 25 ft-lbs (34 N-m). Use caution to
avoid over tightening. Do not exceed 25 ft-lbs
(34 N-m) of torque without consulting Ionpure
Technical Support.
