Hydrotech DLR-A Ultraviolet Water Disinfection Unit - Manual (Page 13)

Pre-Start Up Sequence
Before using
the unit… Follow these steps before operating your WEDECO disinfection unit.
Step Action
1 Check your plumbing:
x Make sure that new plumbing has no leaks.
x Flush pipes to purge soldering residue or other debris from the system.
x 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.
Pour household bleach into your water system. If you have a filter container, fill it with bleach. If you have
no filter then introduces chlorine directly into your well. The amount of chlorine depends upon the
diameter and depth of your well. (Generally, use ½ gallon to treat an 8” diameter/80’ deep well and one
gallon for anything larger.) You may contact your State Extension Service or a water treatment specialist
for additional information.
Open hot and cold water taps throughout the house and let the water run until you detect a chlorine odor.
To ensure that the hot water heater is also purged, allow the hot water to run until the water becomes cold.
Turn off the taps and allow the water to stay in the pipeline for about six hours or overnight but not more
than 36 hours to avoid corrosion.
Open hot and cold water taps throughout the house and let the water run until the chlorine odor
disappears.
Flush the UV system for 5 minutes prior to start-up.
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.
