Step 3: Clean Disinfection Unit Components, cont.
Step 3c:
Use a hose and soft brush to clean the lamp assembly.
• To minimize contamination, clean the lamp assembly over the basin.
• Remove stains from the Teflon
®
sleeve with a soft sponge and detergent.
• Remove stubborn stains with a soft sponge and isopropyl alcohol.
Step 4: Replace Lamp
IMPORTANT:
Wear clean gloves when handling the lamp. Oils from your fin-
gers can damage the lamp and shorten its life!
Step 4a:
Loosen and remove the handle assembly from the lamp tube assembly.
• Make sure the bulb can turn freely in the sleeve while you loosen the handle.
Step 4b:
Disconnect the power cord socket from the old lamp.
• The lamp contains mercury. Dispose of it in accordance with local regulations.
Step 4c:
Connect the power cord socket to the new lamp.
Step 4d:
Gently slide the new lamp and -cord all the way into the lamp tube
assembly.
Step 4e:
Thread the handle assembly onto the lamp tube assembly by hand.
Step 4f:
Use a torque wrench to tighten the handle assembly nut to 35-45 in./lbs
force (4-5 newton-meters).
• Be certain that the o-ring is seated properly to create a waterproof seal.
• Do not overtighten the handle assembly nut.
Step 4g:
If it is necessary to remove and reinstall the cord grip, use a torque
wrench to tighten the cord grip to 35-45 in./lbs force (4-5 newton-meters).
• Do not overtighten the cord grip.
Step 5: Reassemble and Reinstall Disinfection Unit
Step 5a:
Press the lamp tube/handle assembly into the disinfection unit’s housing.
Step 5b:
Slide the disinfection unit’s Q-D male coupling into the Q-D female coupling.
Step 5c:
Firmly seat the Q-D male coupling into the Q-D female coupling.
Step 5d:
Neatly coil the excess power cord and secure it to the splice box if the
wire routing and connection work is not being done immediately.
Step 5e:
Reinstall the lid on the basin and secure it with the lid hardware.
Step 6: Perform Operational Test
Step 6a:
When power is available to the control panel, turn on the circuit
breakers in the control panel.
Step 6b:
Check the numeric display on the current sensor for the UV lamp.
• A normal reading is about 0.38 amps.
• If the sensor reading is 0.20 amps or less, check the lamp wiring connec-
tions and UV bulb.
