It is vital that O-rings are regularly inspected and replaced as the rubber
watertight seal will perish over time, which may cause your unit to leak. Before
replacing your o-rings, ensure they are well lubricated to ensure the seal is
kept water tight.

General Maintenance
It is recommended that every 2-3 months you perform maintenance on your
CUV unit. This is necessary to prevent blockage and inspect the bulb and
quartz sleeve. Make sure to inspect the unit’s cable for damage or excessive
wear.
IMPORTANT!
Disconnect mains electricity supply before handling or
attempting maintenance.

side (CUV-207 / 209 and 211 models only) or using a coin push down the clear
plastic button on top of the ballast (CUV-218 / 224 / 236 / 272 models only).
Gently turn the ballast counter clockwise and pull the ballast apart from the UV
