MOUNTING
Treatment Unit
Location: The Treatment Tank should be within six
feet of the toilet, with the tank located at the same
level or lower than the toilet's discharge. If the tank
is at the same level, or slightly above the toilet, a
vented loop must be installed between the toilet and
the Treatment Tank (see Fig. #2). If the treatment
unit must be mounted more than a few inches higher
than the toilet, contact Raritan Customer Service.
WARNING: DO NOT locate in an area where
ambient temperature exceeds 120
o
F.
Securing Treatment Tank:
1. Make mounting frame (Fig. #5).
2. Secure mounting frame using suitable fasteners.
3. Use 3/4" mounting straps to secure tank to frame
(see Fig. #5). A 3/8" rubber pad (available at a
hardware store) placed under the tank will help to
reduce vibration and noise.
PLUMBING
Use high quality, smooth interior 1 1/2" I.D. sanita-
tion hose to avoid odor problems, available from
Raritan by the foot (part #SH). Discharge from the
toilet enters either side of the Treatment Tank and
exits from the fitting on top of the lid.
1. Connect Lectra/San EC to marine toilet per Fig-
ures #2, #3 or #4. Do not route hose into dips or
valleys and avoid 90
o
fittings where possible.
2. Use teflon tape or nonpermanent thread sealing
compound on threaded PVC fittings and connec-
tions.
3. Determine the orientation of the discharge elbow
provided before gluing with PVC Cement.
4. Double clamp all hose fittings below the water-
line.
Control Indicator Panel
1. Locate an area in the head compartment where
the indicator lights will be readily visible.
2. Using template provided, mark the cutout for the
panel. Do not cut outside of template markings.
3. Route ribbon cable between panel and Lectra/
San EC Treatment Unit. Secure ribbon cable
with cable holders every 18 inches, taking care
not to puncture the insulation or crimp the cable.
4. Plug in the ribbon connection (Fig. #6) to indica-
tor panel and mount panel using four #6 screws.
Salt Feed Tank: (Salt Feed Tank is needed when the
boat will be in fresh water/brackish water.)
1. Assemble the salt feed tank per Fig. #7A.
2. Locate Salt Feed Tank within 6 feet of toilet and
at same level as bowl. Secure tank. Make sure
the tank is accessible for refilling.
3. Attach the T-check valve and tubing to the Salt
Feed Tank.
4. Attach T-check valve in the intake line (suction)
of the toilet. Remove the ball and spring in
Raritan PHII models (Fig. #7).
5. In a separate container, combine five pounds of
rock salt with two gallons of warm water and
allow to dissolve overnight. Pour off water into
tank (this is a saturated salt solution). The salt
remaining in the bottom may be used the next
time.
