locker. Install the plunger retaining nut
and torque to specification.

Manifold Installation
:
Tools required: 3/8" drive Ratchet; 5mm
socket; Soft Faced Hammer; Torque Wrench
1) Place the manifold squarely on the
plungers and push with even tension
until the manifold is seated against the
crankcase. Do not use any lubricant.
2) Replace the manifold bolts and washers.
Torque to specification.

11. Electric Motor [25]: The Electric Motor
requires front and rear bearing lubrication
every 6 months. Give three pumps of high
temperature motor bearing lubricant into each
grease zerc fitting. Use a Polyurea Base Grease
such as Chevron SRI (Polyurea Base) or Shell
Dolium R (Polyurea Base). DO NOT USE
LITHIUM OR SILICONE BASE GREASE.

High Pressure Hose
[27]: The High Pressure
Hoses have no adjustment or repairable
parts. For removal and replacement of a High
Pressure Hose continue here.
a.
Removal
: When removing a High
Pressure Hose use two open end
wrenches. Hold the male flare fitting with
one wrench while loosening the female
swivel nut.
b.
Replacement
: When replacing a High
Pressure Hose use two open end
wrenches. Hold the male flare fitting with
one wrench while tightening the female
flare swivel nut clockwise. Snug finger
tight then, with the open-end wrench,
tighten 1/4 turn (90°) to obtain a metal-
on-metal seal. Never use Teflon tape or
pipe sealant on the flare surface or on the
swivel nut threads.

Reverse Osmosis Membrane Element
[28 &
29]: For cleaning of the Reverse Osmosis
Membrane Element refer to Section 8 of
this Manual. For installation/replacement
of the Reverse Osmosis Membrane Element
continue here.
The Membrane Vessel Assemblies have a
side port design. As such, dual membrane
systems (740-2, 1160-2, and 1480-2) require the
Membrane Vessel Assemblies to be removed
from their respective frames prior to servicing.
Access permitting, single R.O. Element
systems (420-1, 630-1, and 840-1) may be
serviced in place.
Dual Vessel System Preparation :
1.) Disconnect the Brine and Product tube
connections located on the right side of
the Control Manifold. Next, remove the
four ¼" nuts from the right side of the
Control Manifold Assembly that hold it
to the Membrane Vessel Assembly. Slide
the assembly from the vessel and set in a
secure place.
CAUTION
: Electrical Connections to the
High Pressure Switch [32], the Diversion
Valve [43], and the Salinity Probe [41]
remain connected.
2.) Disconnect the High Pressure Hose [27].
3.) Remove the product tubing, black plastic
fittings, and stainless steel nipple from the
Membrane Vessel end plugs. (The vessels
cannot slide out from the Vessel Frames if
the product fittings remain attached)
4.) Next, loosen and remove the two ½"-13
hex cinch bolts on the Vessel Frame/Wall
Mounted Vessel Frames. (These bolts
slightly deflect these Vessel Frames to
clamp the vessel. As such, the bolts are
very snug.)
5.) Slide the Membrane Vessel out from the
Vessel Frames. They may now be serviced.
a. Removal of the Reverse Osmosis Membrane
Element:
NOTE
: It is highly recommended to
replace all O-Rings within the High
Pressure Vessel assembly each time the
Reverse Osmosis Membrane Element is
removed or replaced. Each single High
Pressure Vessel assembly contains a total
of 6 O-Rings (4 each Brine O rings and 2
