See description of propylene glycol formulations, and flushing from system, on page 33 - 34.
1. Close the saltwater intake seacock.
2. Push the Freshwater Flush button to perform a flush. Repeat a second flush.
3. Disconnect the brine discharge hose from the Clark Pump at quick disconnect. Replace with the vinyl brine
discharge service hose* from your service kit. Lead hose into a 5 gallon bucket.
4. Push Freshwater Flush and stop with one gallon of freshwater in the bucket (or use distilled).
5. There are two gallons of water in the watermaker, so add potable water antifreeze to the bucket per the
label instructions based on the protection level needed.
6.
Connect black spiraled intake reinforced service hose** to the service port (garden hose style fitting) above
the yellow valve on the feed pump module and lead the hose into the solution in the
bucket, creating a closed loop. Turn the yellow service valve handle to
SERVICE.
7. Ensure the pressure relief valve on the Clark Pump is OPEN 1/2 turn (unpressurized).
8. If a stronger concentration of antifreeze is required you can discard the first one or two
gallons of water from the discharge line before placing it into the bucket to recirculate. Add
more propylene glycol to the intake bucket if necessary. Turn on the feed pump using the
manual toggle switch*** and the pump will draw propylene glycol from the bucket, and the brine discharge
service hose will return it, creating a closed loop. Run the feed pump and circulate the antifreeze for
approximately 20 minutes. Stop the feed pump by moving the toggle switch back to
‘ RUN AUTO ’.
Clean Up:
1. Remove the brine discharge service hose from the Clark Pump, and replace with the original brine discharge
hose that leads to the thru
- hull. You may now pump the bucket dry by engaging the toggle switch again. Stop
when the bucket is empty, switching back to ‘ RUN AUTO ’.
2. Turn the yellow service valve handle to OFF . Disconnect the intake service hose and replace cap.
3. Drain the seawater strainer and the hose leading to the feed pump module. Disconnect the product tubing
from the membrane housing and blow residual water out of the tubing. Empty the charcoal filter housing
and flush water lines.
Your system is now protected from biological growth and freezing for 12 months.
