UV Sterilizer Upgrade Instructions
Important Safety Precautions It is recommended that you plug the chiller into a GFCI outlet at all times. Do not operate SeaChill chillers or any accessory to SeaChill chillers (heater or UV sterilizer) without water flow. Overheating of lamp or heater may occur. After installation, monitor unit for at least an hour to confirm there are no leaks. DO NOT LOOK DIRECTLY AT ULTRAVIOLET LAMP WHEN ON.
Parts needed for UV installation.
Unscrew the Ring Nuts and remove the shut off valves from the chiller. Use channel lock pliers or similar to loosen plastic nuts holding the housing in place. It is not necessary to grip nuts tightly, a loose grip will help prevent scarring of plastic. If desired, a piece of duct tape may be used to cover the teeth of the channel lock pliers to prevent scarring of the plastic nuts. Once loosened, manually remove the plastic nuts.
Remove air filter from chiller housing. Pull upwards on rear of chiller housing, loosening it on the frame of the chiller. Insert fingers between housing and frame of the chiller at the front. Once fingers are between frame and housing, lift upwards.
Unscrew and remove ring nut over UV port. Remove plug and o-ring from ring nut. Place o-ring over the top of the quartz sleeve and push down approximately 3/4 inch to 1 inch onto the quartz sleeve. Insert quartz sleeve into heat exchanger until o-ring seats into outlet lip. If you encounter resistance while inserting the quartz sleeve, gently turn sleeve and apply very slight force.
Put ring nut over quartz sleeve and o-ring. Tighten to seal. Use channel lock pliers or similar to insure there is no leak.
Slide the rubber plug along the wiring until it is directly against the 4-pin connector. Carefully bend the copper capillary tubing to make space for the ballast. It is helpful to look ahead and see where the ballast will mount to determine how to move the tubing. Be careful not to crimp or break the tubing. Line the holes in the ballast mounting plate with the holes in the strut supporting the compressor.
Attach the ballast by screwing the ballast onto the strut supporting the compressor. Pull the wiring harness forward and attach the harness to the ballast mounting plate with a zip tie. Use zip ties to gather wires together. Clip excess plastic from zip ties with wire cutter.
Take UV lamp and insert pins into 4-pin connector on wiring harness. Note: DO NOT touch the UV lamp as finger oil will damage the lamp. Insert UV lamp into quartz sleeve. Push plug firmly into quartz sleeve until it is flush with the top of ring nut.
Connect two pin adapter on wiring harness to two pin connector mounted on top of support strut. Use zip tie to fasten wiring harness to support strut.
Mount UV starter onto the ballast by inserting pins into slots and rotating clockwise 1/4 turn.
Plug in and turn on the chiller At the top of the control panel, above the display and controls are a series of small metal prongs. Remove the plastic “jumper” from the first two prongs. Place jumper on pins 7&8, this will reset your chiller. Remove jumper from pins 7&8. Now turn off your chiller. CAUTION: Leaving chiller on with no water flowing will cause the unit to overheat. Place Jumper over pins 2&3 (see diagram below) Note: Resting your chiller will change your set temperature to the default of 73.
Turn on power switch Turn on UV by pressing button on the front panel. You should see a glow around the rim of the quartz sleeve indicating the UV is working. Immediately turn off chiller after verifying the lamp is working. CAUTION: Do not look directly at the UV Lamp, UV light is damaging to your eyes. CAUTION: Turn off chiller after checking lamp - Leaving chiller on with no water flowing will cause the unit to overheat.
After verifying the UV Lamp is working, turn chiller off and unplug power cord. Lower housing over chiller. It is important to line up housing with the control panel. If the control panel does not fit the slot designed for the control panel, housing is not seated correctly. Press down firmly an on the rear of the housing. You will feel the housing snap into place. Replace plastic nuts over threaded inlet and outlet ports. Tighten with channel lock pliers. Replace shut off valves.
