e. If your EUV unit is installed on a swimming pool, shock the pool with the sanitizing chemical you
normally use and balance the pool water as per your chemical manufacturers specications.
18.5 The GFCI Has Tripped - The GFCI protects the system from any fault to ground, as the electrical
breaker protects the electrical circuit. When it trips, it is an indication that there is an electrical problem
that must be corrected to provide a safe operating environment in your pool or pond.
a. GFCI Not On End Of Power Cord - Disconnect the EUV unit from the electrical receptacle.
Reset the GFCI at the breaker panel or at the receptacle. If the GFCI does not reset, replace
the GFCI. If the GFCI does reset, plug the EUV unit into the electrical receptacle and make
sure the pump is on. If the GFCI trips, it is an indication that there is a ground fault inside the
EUV unit. Follow instructions previously given for opening the electrical enclosure bonnet and
inspecting the EUV unit.
b. GFCI Is On End Of Power Cord – Try to reset the GFCI – If the GFCI won’t reset, inspect the
power cord for fraying or damage and if none is found, unplug the power cord from the electrical
receptacle.
c. If water is present inside the electrical enclosure bonnet, it will trip the GFCI. Following instructions
given previously, remove the quartz tube, inspect it for cracks or breakage or for a bad quartz
tube seal. Re-seal the quartz tube.
d. Regardless of where your GFCI is located, you can check the UV bulb for GFCI trip cause by
unplugging the bulb from the bulb connector, then place the electrical enclosure bonnet back
on the EUV unit and power up the circulation pump. Reset the GFCI and if it does not trip, it
indicates that the UV bulb is causing the fault to ground. Replace the UV bulb. If the GFCI does
not reset, then the problem is with the Ballast. Replace the ballast.
18.6 The EUV Unit Makes Noise When Operating - This is an indication of the EUV unit not being
properly attached to a rm mounting base of wood or concrete with the bolts placed through the mounting
holes in the EUV unit base. It can also indicate that the UV bulb was installed without the required bulb
cushion and/or bulb O’Rings. Attach the EUV unit correctly to a rm base as described in Sec. 5.5, or
install the bulb cushion and/or bulb O’Rings as described in Sec. 9.0.
18.7 Water Is Coming Out Of Electrical Enclosure - Water exiting the unit through the electrical enclosure
bonnet can be attributed to either (a) a bad quartz tube seal, or (b) a broken or cracked quartz tube. Check
the quartz tube seal and quartz tube as instructed in Sec. 7.0 and Sec. 8.0.
