Hallett 30 1” Instruction Manual

Caution: The quartz sleeve can break or chip if mishandled. Always handle it

with care and keep it in a safe place if it is removed from the unit. Do not strike

the quartz sleeve with any tool, since even the smallest chip can cause it to

break under pressure.

In-place cleaning

Note that numbers in parentheses refer to Figure 4B.

This procedure will clean the quartz without its removal from the unit. This is a

quick and easy procedure that works well in most cases.

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 (4). A squeeze

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

sleeve.

Step 2: Open the unit and remove the lamps and reflectors (see Determining the

Need for Cleaning).

Step 3: Place another bucket under the unit and drain the unit until there is about

1” (3cm) of water left in the quartz sleeve (see Draining the Unit).

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 (see Step 7 in the Disassembling the Unit

section) 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 Hallett unit.
