Mounting Options
See the “Mounting Methods” drawing in Chapter 10.
Mount the module(s) so that the bolt heads are accessible with a torque wrench if it is
necessary to torque the module.
The module can be mounted in different ways. The most popular way is to install L-or U-
brackets on the skid, which provide a secure track for module to sit in. The module may
be mounted on a single, central rectangular rail. The module is then secured at the top
via either two of the mounting holes on the top. The module may also be suspended by
3/8” rods through the same four holes on the top. It is recommended that the plumbing
side of the module(s) be secured to reduce or prevent the movement or strain on the
plumbing due to possible expansion or contraction of the module.
► Do not bolt both the front and rear of the module to fixed points as this can
constrain and stress the module hardware during torqueing. One of the
endplates needs to be able to move to allow unrestricted torqueing.
Module Orientation
SnowPure’s EDI modules are designed to be installed in an upright, or vertical, position.
Gases can become trapped in the chambers and interfere with ion removal if mounted in
a horizontal position.
Pipe and Tubing Connections
The standard XL modules are provided with
1” female pipe thread (FNPT) fittings for the
main feed and the product. These connections are made of high strength engineering
plastic.
It is very important that the threads are protected before installation to prevent damage
and subsequent leaks. Secure the fittings with a tool to prevent twisting them during
threading.
If the fittings are not “backed up” during tightening, they may crack and need
to be returned to the factory for repair.
Use Teflon
®
tape or pure TFE paste for sealing the threads;
do not use pipe dope
(sealant) made for metal threads as it often contains solvents that will weaken the
polymer fittings.
Even “FDA-approved” pipe sealants contain these solvents. The use
of pipe dopes with solvents will void the SnowPure warranty. SnowPure has some
approved pipe sealants that do not harm the EDI materials.
Do not over-tighten the threads. Starting with the second full thread and continuing over
the length, wrap Teflon thread tape in the direction of the threads. Overlap each wrap by
one-half the width of the tape. Screw the male fitting into the 1" female port (be sure to
backup this fitting) on the module and tighten by hand. Using a strap wench only, further
tighten the connection an additional one to two threads past hand tightness. Avoid
excess torque as this may cause manifold or fitting damage. Read the full threading
instructions accompanying the module.
