Pre-Start Up Sequence
Before using
the unit… Follow these steps before operating your WEDECO disinfection unit.
Step Action
1 Check your plumbing:
• Make sure that new plumbing has no leaks.
• Flush pipes to purge soldering residue or other debris from the system.
• Expel air from the system to avoid pressure damage to the unit.
2 Before initial use of your UV system and after routine maintenance procedures, you should
sanitize your water system to ensure that no organisms are present. (See Maintenance section for
instructions)
Flush the UV system for 5 minutes prior to start-up.
3 Insert the solenoid valve plug into the solenoid valve receptacle located on the bottom of the
electrical box.
Note: Solenoid is optional. WEDECO recommends installing the solenoid valve, which will shut
off water supply in the event that certain alarms are triggered (see Alarms & Troubleshooting
sections).
4 Check that the grounding is properly installed before powering up the system.
Plug one end of power cord into receptacle on the bottom of electrical control box, making sure
plug is pushed in completely.
IMPORTANT! Do not plug power
cord into wall outlet until you
begin the start-up sequence.
