6.
Flush thoroughly (at least 5 gallons) with fresh water to clear carbon fines. Test outlet water
with TDS (Total Dissolved Solids) Meter to determine exact flushing volume required.
7.
Once rinsed, reinstall the filters. The PU-4029 (CBC) filter should be installed in the filter
port that is on the left side of the faucet and the PU-4076 (GAC) should be installed in the
filter port on the right side of the faucet (as you face the front of the machine).
Internal Filter Bypass Instructions
The
WL500
has a CBC Filter and GAC Filter installed behind the front access panel. These filters
are reverse thread and the first filter head has an internal shut-off valve that requires a filter to
be engaged to allow water to pass through it. Alternative filtration may be required to best
meet your local water and business needs. The
WL500
internal filter heads can be bypassed
internally by removing side panels and running a new ¼” JG tube from the inlet bulkhead to the
inlet solenoid tee. Always check for leaks after installing and ensure the tubing is routed away
any moving or hot parts to avoid potential damage.
Sanitizing
Sanitize using a household bleach solution or other approved cleaner throughout the cold and
sparkling water circuits. Follow all instructions on the sanitizer and flush with fresh water
through the faucet until odor and taste is acceptable.
WARNING!
USE PROPER PERSONAL PROTECTIVE EQUIPMENT
Always ensure proper ventilation and use proper personal protective equipment such as gloves
and eye protection when using chemicals. Refer to Material Safety Data Sheet for specific
requirements of each chemical product. Take all necessary precautions to prevent sanitizer from
contacting eyes, clothing, and any other surfaces in could damage (carpets).
8.
Remove the UV Cover Plate and set aside – 2 Screws.
9.
Disconnect the UV Lamp harness and carefully remove the UV Lamp from the quartz sleeve.
CAUTION!
UV SYSTEM IS FRAGILE.
Never handle the UV System with bare hands. UV
Lamp and quartz sleeve must be free of oils and contaminants to ensure proper operation.
10.
Remove UV Sensor from the side of the cold tank/quartz sleeve retaining cap.
11.
Unscrew cold tank/quartz sleeve retaining cap and remove the quartz sleeve. This may
require top cover to be removed to access properly and facilitate removal.
12.
Mix ½ gallon of sanitizer per directions or use Bleach Solution (1 teaspoon = 1/6 oz. = 5 ml =
½ cap full) of household bleach (Sodium Hypochlorite 5 - 10% Concentration) with 1/2
gallon of water. Always ensure sanitizer is compatible with stainless steel and acetal plastic.
13.
Pour sanitizer solution into cold tank thru funnel or spout. You may add concentrated
sanitizer (½ cap bleach) directly into empty cold tank instead of premixing.
14.
Inspect and clean quartz sleeve and O-ring. Reinstall the quartz sleeve and quartz sleeve
retaining nut. Tighten firmly to ensure proper seal. Over-tightening can cause damage.
15.
Reinstall the UV Lamp and UV Sensor. Take care not to touch with fingers.
