WARNING - WINTERIZING AND
FREEZING TEMPERATURE STORAGE:
If the system is exposed to freezing
temperatures, DO NOT activate
the Automatic Fresh Water Flush.
Instead, perform a Manual Fresh
Water Rinse below.
MANUAL FRESH WATER RINSE PROCEDURE
Follow the directions below if the system is not equipped
with an Automatic Fresh Water Flush option, or if the
System is to be Winterized against freezing temperatures.
This procedure displaces the system feed water with
fresh water and allows a short-term shutdown for up
to four weeks, and adds propylene glycol if Winterizing.
Ten gallons (38 liters) of fresh product or potable water
is required for the fresh water rinse, and 2 gallons (7.5
liters) food grade glycerin (propylene glycol) is required
for Winterizing.
1.
Close the Inlet Sea Cock Valve.
2. Fill a 10-gallon container with clean, fresh water.
WARNING : IF THE SYSTEM
WILL BE EXPOSED TO FREEZING
TEMPERATURES add 20% (2 gallons or
7.5 liters) food grade glycerin (propylene
glycol) to 10 gallons (37.8 liters) of potable
water in the Bucket. This prevents the
water in the system from freezing.
3. Configure the system for a Once Through Rinse
(Page 7-7, fig 7a).
4. Start the System in the MANUAL MODE
Operation of the System will deplete the Fresh
Water or Water and Propylene Glycol mixture in the
bucket. Just prior to depleting the Water or mixture
in the Bucket Stop the System.
5. Proceed to Section 7.5.
7.4 LONG TERM SHUTDOWN
A Long Term or Prolonged Shutdown is a period in which
the system goes unused for longer than three months,
depending on conditions.
For this interval, the system should first be rinsed with
fresh water then stored with system and Membrane
Element Storage Chemical (SRC SC). This chemical
inhibits bacterial growth while maintaining the high flux
and salt rejection of the R.O. membrane element.
When the instructions within this section state “configure
for Once Through Rinse” refer to page 7-7, figure 7a and
proceed as follows:
1.
Configure the Suction line for a Once Through
Configuration as illustrated on Page 7-7.
Disconnect the outlet line from the Sea Strainer
and place it in the Rinse/Clean Bucket or Container.
Or if the system is equipped with the optional Rinse
Clean Inlet Valve then position this valve to draw
from the Rinse/Clean Bucket or Container.
also
2. Configure the Brine Discharge line for a Once
Through Configuration as illustrated on Page 7-7,
Fig. 7a). Connect the Brine Discharge Line from
the system to the Thru-Hull over board discharge
fitting, normal connection for normal operation.
Or if the system is equipped with the optional
Rinse Clean Outlet Valve then position this valve
to discharge through the Thru-Hull fitting, normal
connection for normal operation.
When the instructions within this section state “configure
for Closed Loop”refer to page 7-7, figure 7b and proceed
as follows::
1.
Configure the Suction line for a Closed Loop
Configuration as illustrated on (fig. 7b). Disconnect
the outlet line from the Sea Strainer and place it
in the Rinse/Clean Bucket or Container. Or if the
system is equipped with the optional Rinse Clean
Inlet Valve then position this valve to draw from
the Rinse/Clean Bucket or Container.
also
2. Configure the Brine Discharge line for a Closed
Loop Configuration (fig. 7b). Disconnect the Brine
Discharge Line from the Thru-Hull over board
discharge fitting and place it in the Rinse/Clean
Bucket or Container. Or if the system is equipped
with the optional Rinse Clean Outlet Valve then
position this valve to return to the Rinse/Clean
Bucket or Container.
7.3 SHORT-TERM SHUTDOWN
A short-term shutdown is defined as a period of time in
which the system is not utilized for up to four weeks. An
effective short-term protection for the system and R.O.
membrane element is a 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.
