Step 2: Shutdown and unplug the unit from the electrical outlet. 
Step 3: Place a bucket under the unit to collect the water. 
Step 4: Open a faucet downstream of the unit. 
Step 5: If you have installed the optional drain valve, open the drain valve. If you 
do not have an optional drain valve, disconnect the Stainless flexible hose below 
the unit and allow the system to drain for a few minutes. 
Step 6: When draining is complete, close the drain valve or reconnect the flexible 
hose. 
Step 7: Close any faucets that were previously opened. 
Cleaning the Unit 
UV Pure has designed the automatic quartz cleaning within the Hallett to virtually 
eliminate the disassembly and cleaning of the quartz - the quartz will remain 
clear and transparent as glass. If a component of the cleaning device fails, such 
as the wiper motor, or in extreme water cases the quartz may become fouled and 
require manual cleaning. In this situation the Treatment alarm will arise and alert 
you to the unsatisfactory conditions. Follow the steps below to inspect the quartz 
and disassemble the unit for quartz cleaning. 
Caution: Always shutdown and unplug the unit before performing any 
maintenance. Never operate a unit unless the front panel is completely secured.

Determining the Need for Cleaning 
Step 1: Shutdown and unplug the unit. 
Step 2: Remove the top cover by pulling each side of the plastic top cover 
outward from the unit, and loosen the wing nuts or thumb screws. 
Step 3: Tilt and hold the front panel until it comes to rest at a 45 position. 
Step 4: Examine the quartz sleeve both inside and out. If it is clean, no 
disassembly is required. Return the front panel to the upright position and tighten 
wing nuts. Plug in the unit and operate as normal. 
If the quartz sleeve is dirty on the outside, proceed to wipe it down with a clean 
lint-free cloth and rubbing alcohol to remove the dirt. If the quartz sleeve is dirty 
on the inside, proceed with in-place cleaning or disassembly. 
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
