UNIT MAINTENANCE PROCEDURES
REVERSE OSMOSIS SYSTEM
3. Install the new turbocharger to the base plate as follows (see Figure 14):
a. Clean the external threads of the straight and elbow fittings.
b. Wrap antiseizing tape on the threads at both ends of the straight fittings and screw them
into the bottom of the turbocharger.
c. Secure the base plate to the turbocharger using the four caps crews, four lock washers,
and four flat washers.
d. Wrap antiseizing tape on the threads of the elbow fittings and screw the elbow fittings into
the straight fittings at the bottom of the turbocharger. Make sure the elbow fittings point
out to the front of the turbocharger.
e. Move the drain valves into place on the base plate and screw the drain tube nuts onto the
elbow fittings under the turbocharger.
4. Install the turbocharger assembly onto the TWPS as follows (see Figure 13):
a. Inspect the four 1-in. diameter grooved coupling gaskets for damage or deterioration and
replace if needed. Lubricate with glycerin and slide the gaskets over the RO feed and
reject inlet and outlet pipes.
WARNING
The turbocharger feed and reject inlet and outlet pipes must be installed to the
correct system feed and reject inlet and outlet pipes. Failure to observe this
warning can result in injury or damage to equipment.
b. Apply corrosion preventive compound to the turbocharger mounting studs that are still
threaded into the TWPS floor (see Figure 14).
c. Set the turbocharger in place so that the holes in the base plate fit over the studs. Make
sure the valves are facing the front of the TWPS.
d. Set the valve bracket into place.
e. Secure the valve bracket and base plate to the studs with the four flat washers and four
lock nuts. Tighten evenly.
f. Reconnect the "S" shaped reject out pipe to the RO vessel #5 reject out pipe.
g. Reposition the grooved coupling gaskets to fit over the ends of the turbocharger inlet and
outlet pipes and their matching RO feed and reject inlet and outlet lines.
h. Secure the turbocharger inlet and outlet pipes to the RO feed and reject inlet and outlet
lines using the grooved couplings.
i. Reconnect the two plastic drain tubes.
j. Place system back into service and inspect for leaks.
