USE OF NON-AUTHORIZED OR MISUSE OF AUTHORIZED
CHEMICALS VOIDS SYSTEM WARRANTY
Do not connect any water line to the system that may contain any of the
aforementioned chemicals. Example: Do not connect the inlet of the system
to the ship’s potable water system if the ships system contains chlorinated
or brominated water. These chemicals destroy the copolymer components
within the R.O. system. These oxidants and others also damage the R.O.
membrane element. If equipped, the fresh water flush system can be used
to remove chlorine and bromine from the ship’s potable water system.
DO NOT PERFORM INSTALLATION UNLESS:
1 The system feed water sea cock valve is closed.
2 The system main electrical disconnect switch is switched
“OFF,” LOCKED,
and
TAGGED
.
3 A volt/ohm meter will be necessary.
WARNING: ELECTRICAL SHOCK HAZARD
. The installation
procedures expose the installer to
HIGH VOLTAGE
and electrical
shock hazard. Only attempt installation if you are a qualified
electrician and only if surrounding conditions are safe.
QUALIFICATIONS
Technicians must have technical knowledge and ability
in the following fields:
a) Electrical, Electronic, Electric Motors and Circuits
b) Electromechanical and Mechanical Systems
c) Hydraulic and Liquid Pressure and Flow Systems
d) Piping and Plumbing Systems
e) Water Suction and Pressure Lines
f) Thru-Hull Fitting below and above water level
WARNING:
Do not attempt installation, commissioning, troubleshooting,
or repair if you are not proficient in the above fields of expertise.
SPECIAL CONSIDERATIONS INSTALLATION CAUTIONS
Do not over tighten PVC fittings. If threaded pipe fittings leak after installation,
remove the fitting, clean the mating threads, apply 3 to 4 wraps of Teflon tape to
the male threads, apply liquid Teflon pipe sealer sparingly, and thread the parts
back together. PVC fittings should only be hand tightened without the use of a
wrench. The sea cock valve, in-line pressure gauge (if equipped), sea strainer,
rinse-clean inlet valve (if equipped), and low pressure pump should be installed
at or below water level. This will aid the low pressure pump in priming.
Always allow hoses and tubes to enter and exit straight from the
connection for a minimum of one inch prior to a bend. If stress is placed
on the fitting due to a tight bend the fitting will leak and may break.
