Dry Testing with an Artificial Ocean
If it is not possible to test run the system with the boat in the water, you may test the system
with an artificial ocean. You will need 1.3 lbs. of non-iodized salt (rock salt, sea salt, or aquarium
salt) to make a 5 gallon (605 grams of salt per 20 liters) of water that is about 33,000 PPM salini-
ty (average seawater salinity). A rule of thumb is 1/2 cup (.12 liters) of salt per gallon (4 liters) of
water. Make sure the domestic water system is powered up and the boat’s tank has at least 30
gallons (120 Liters) of water to purge the storage chemicals from the system. Confirm that the
charcoal filter is installed in the feed pump module, and the domestic water line is connected.
1. Open the pressure relief valve on the Clark Pump. Remove the green tag and spacer.
2. Turn the yellow service valve on the feed pump module to OFF. This is the center (horizontal)
position. See Figure 1.
3. Power up the control. Bypass the purge mode by pushing Stop and AutoRun
simultaneously. “PURGE MODE BYPASSED” should appear.
4. Push the Auto Store button and allow the system to run a full flush cycle. Do
this six times to purge the storage chemicals.
5. Connect the inlet and brine discharge service hoses per Figures 2 and 3, and
route them into the 5 gallon (20 liter) bucket. Disconnect the product tube from the diver-
sion valve, and using another small piece of tube, route it into the bucket.
6. Push the Auto Store button one or two more times to fill the bucket with fresh water from
the brine discharge service hose (hose attached to Clark Pump). Press Stop when the bucket
is full.
7. Rotate the yellow service valve to the SERVICE position.
8. Mix the salt to the proper proportion or use an aquarium hydrometer to adjust the salinity
level. If a hydrometer is available, mix to a specific gravity of 1.025.
9. Push the Auto Run button, allow the system to prime and then close the pressure relief
valve. The system should build pressure and after several minutes start making water, with
the brine and product water recombining in the bucket to be cycled again. This will gradually
heat the water. Do not let the water temperature exceed 120 deg. F (49 deg. C).
10.Run the system under pressure, checking for proper operation and leaks. After testing the
system, replace the brine discharge hose and product tube, and turn the service valve to
RUN. You can now flush the system by pressing the Auto Store button.
