FCI WATERMAKERS, INC. 118 Maintenance & Repair
CLEANING AND STORAGE PROCEDURES
Invariably there will be times when the watermaker will not
be used. During this time, it is recommended that the system
be shut down and certain precautions are taken. By following
these simple instructions, your FCI system will continue
to provide you with fresh water for years to come.
SHORT TERM SHUTDOWN (UP TO 6 MONTHS)
You can perform a fresh water flush cycle before shutdown, and no additional
procedures are necessary. For systems without the flush installed, it is
recommended to manually run fresh water through the system at “0” high
pressure, until the majority of the seawater has been displaced by fresh water.
LONG TERM
If the system has fresh water flush installed, set the control system to automatically flush
the system every week. Another method is to “pickle”, or preserve the system, which
will last up to six months. Please refer to "STORAGE PROCEDURE" on page 121.
WARNING: FRESH WATER FLUSH
There must be sufficient fresh water in the potable water storage tank:
In order to provide the required flow of water to the system during
the fresh water flush cycle, the boat or home’s fresh water pressure
system must deliver minimum 1 U.S. Gallons (3.8 Liters) Per Minute
at minimum 25 PSI (172 kPa) and maximum 60 PSI (414 kPa).
WARNING: FREEZING TEMPERATURE
The system must be protected from freezing if it will be exposed to
temperatures below 32º Fahrenheit (0º Celsius). Freezing temperatures
(below 32º F / 0º C) will cause extensive damage to the system as the water
expands within the system during the freezing process. Resulting damage to
the system caused by freezing temperatures is the liability of the operator.
DO NOT subject the system to temperatures below 32º Fahrenheit (0º
Celsius) unless the system has been rinsed with a solution of product water
with twenty percent (20%) food-grade glycerin (propylene glycol).
NOTE: USE OF CHEMICALS
Although chemicals are necessary in some instances, FCI recommends
using them only as needed. The chemicals can attack the membrane
polymers and weaken the integrity of the membrane.
