A. SHORT-TERM SHUTDOWN:
A short-term shutdown is defined as a period of
time in which the Horizon Seafari system is not
utilized for two to fourteen days. An efficient
short-term method of protecting the HRO system
and R.O. membrane element is to perform a "once
through" Fresh Water Rinse of the entire system
with fresh water (product water from the system).
This prolongs the system life by minimizing
electrolysis and retarding biological growth.
Refer
to page H – 1 for complete explanation of the
Fresh Water Flush System.
ONE TIME THROUGH FRESH WATER
RINSE PROCEDURE:
Follow the directions
below. This procedure displaces the system feed
water with fresh water and allows a short-term
shutdown for up to two weeks. 10 to 20 gallons (38
to 75 liters) of fresh product or potable water is
required depending upon the Optional Pre-filtration
included with the system. Refer to the Once
Through Rinse diagram on page J – 2.
1. Close the Inlet Sea Cock Valve [2].
2. If not already connected, connect the
RINSE/CLEAN INLET line from the
Rinse/Clean Inlet Valve [4] to the pick up point
of the Rinse/Clean Tank [50].
3. Fill the Rinse/Clean Tank [50] full with non-
chlorinated product water. The cleaning tank
must contain enough product water to sustain
rinsing of the system until all of the feed water is
displaced. This process requires approximately
10 to 20 gallons (38 to 75 liters).
WINTERIZING AND FREEZING
TEMPERATURE STORAGE NOTE:
If the system is exposed to freezing temperatures
add twenty percent (2 to 4 gallons / 8 to 15 liters)
food grade glycerin (propylene glycol) to the
rinse water. This prevents the water in the system
from freezing.
4. Position the Rinse/Clean Inlet Valve [4] to the
Rinse/Clean Tank position.
5. Position the Rinse/Clean Outlet Valve [35] to the
Brine Discharge (normal operation) position.
6. Fully open the Back Pressure Regulating Valve
[33].
7. Operate the system by pressing the “Start” switch.
The fresh water rinses the entire Horizon Seafari
system and discharges out to waste.
8. Apply 200 psi of pressure to the System by turning
the Back Pressure Regulator Clockwise. This
allows the system to produce a minimal amount of
product water, which ensures that the product
water line remains wet.
9. Just prior to depleting the rinse water from the
tank, stop the system.
10. Position the Rinse/Clean Inlet Valve [4] to the
Normal Operating Position towards the Sea
Strainer [3]. The system is now exposed to fresh
rinse water and may be left unattended for up to
two weeks. This procedure should be repeated
every two weeks if the system is not in use.
NOTE: If the Horizon Seafari is equipped with a
Fresh Water Flush system, the fresh water flush is
a substitute for the above procedure. The Fresh
Water Flush is timed and repeats every seventh
day unless the “Stop” switch is pressed, or the
power supply is interrupted.
B. LONG TERM SHUTDOWN:
A Long Term or Prolonged Shutdown is defined as a
period in which the HRO system is shut down for
longer than three months. For a such a shut down,
the system should first be rinsed with fresh water,
then stored with HRO SC System and Membrane
Element Storage Chemical. This chemical inhibits
bacterial growth while maintaining the high flux and
salt rejection of the HRO R.O. Membrane Element.
Follow the directions listed below.
The Long Term Shutdown procedure requires 20 - 40
gal. (75 - 150 liters) of potable water.
1. Backwash and rinse the Multi Media Filter, if
installed.
2. Close the Inlet Sea Cock Valve [2].
3. Replace all of the Pre-filtration Cartridges with
new HRO Pre-filtration Elements.
4. If not already connected, connect the
RINSE/CLEAN INLET line from the Rinse/Clean
Inlet Valve [4] to the pick up point of the
Rinse/Clean Tank [50].
