Heater 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. To avoid potential electric shock, care should be taken since aquarium equipment involves use of electricity and water.

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 Heater port. Remove plug and o-ring from ring nut. Place o-ring over the top of the Heater and push down approximately 3/4 inch to 1 inch onto the Heater. Insert Heater into heat exchanger until o-ring seats into outlet lip. If you encounter resistance while inserting the Heater, gently turn the Heater 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.
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.
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 prongs 4 and 5. 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 5&6 (see diagram below) Note: Resting your chiller will change your set temperature to the default of 73.
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. Chiller is now ready for operation. Once water is flowing through chiller, check carefully for any leaks.
