Upstream Instruction Manual

*Do not replace the fuse in the unit if it blows. A blown fuse indicates major circuit

board fault. Replace entire circuit board. Inspect lamps-replace if discolored.

Step 4: Disconnect the top hose from the plumbing side (not the unit side but

other end).

Step 5: Add about 2 oz. (60cc) of cleaning solution to the top hose. The cleaning

solution can be a citric acid, vinegar or other non-hazardous solutions. Any

solution used should be thoroughly rinsed out afterwards. Fill the rest of the

quartz with water.

Step 6: Let the cleaning solution remain in the quartz for at least 10-20 minutes.

Step 7: Manually turning the wiper may greatly assist the cleaning process. To

do this, remove the motor assembly and turn the wiper shaft with a flat-bladed

screwdriver (counterclockwise while looking at the shaft).

Step 8: Drain the unit and inspect the quartz sleeve. If clean, flush the unit with

clean water. If fouling remains, repeat procedure.

Step 9: Once the unit is clean, reassemble the unit including the motor and top

hose connection.

Step 10: Slowly open the water supply and check for leaks.

Step 11: Replace all covers and plug in the Upstream unit.

Disassembling the Unit

NOTE: This procedure is not recommended for individual household users

please contact your certified water specialist to assist should disassembly be

required.

Step 1: Fill a bucket or container with water before shutting off the water supply

since you will need the water later to clean the quartz sleeve (11). A squeeze

bottle is useful for applying water or cleaning solution to the inside of the quartz

sleeve.

Step 2: Place another bucket under the unit and drain the unit (see Draining the

Unit).

Step 3: Open the front panel. The lamps may be removed to prevent them from

getting dirty or damaged.

Step 4: Disconnect the Stainless flexible hose (8) from the top of the unit and

remove the top quartz seal assembly.

Caution: Do not damage the sealing surfaces of the end caps (5 and 19) or the

shaft of the wiper assembly (12). Handle these parts with care to prevent water

leaks.
