b. Installing the UV Lamp
i. Make sure to handle the new lamp by the ceramic endcaps and clean the UV Lamp before
installation if needed.
ii. Slowly place the UV Lamp into the Lamp Retainer until the top of the UV Lamp is pushed
past the tabs on the Lamp Retainer.
iii. Connect the Lamp Connector to its corresponding part in the Ballast Assembly.
ENVIRONMENTAL NOTICE: UV Lamp CONTAINS MERCURY. Manage in accordance with disposal
laws. See: www.lamprecycle.org
c. UV Reactor Service and Maintenance
The UV Lamp is housed in a Quartz Tube. If the Quartz Tube becomes dirty, its ability to transmit
rays from the UV Lamp will be diminished and decrease system performance. The Quartz Tube
should be removed from the UV Reactor at least once a year or during a routine swim spa water
change for inspection and cleaning if necessary.
d. Quartz Tube Removal and Cleaning
CAUTION: Wear proper eye and skin protection for servicing glass components.
i. Make sure the swim spa is shut down and the UV Lamp and Quartz Tube have cooled
before performing maintenance on the Quartz Tube. If you have installed Isolation Valves,
close them before servicing. If you do not have Isolation Valves, the swim spa must be
drained below where the Spa Solar Eclipse is mounted.
ii. Remove the Upper Enclosure Assembly and UV Lamp as described in Section A and set aside
in a safe place.
iii. Remove the two Retainer Screws and Retainer Washer from the top of the Lamp Retainer
and slowly pull the Lamp Retainer out of the UV Chamber Cap.
CAUTION: If there is any water remaining in the plumbing, it will start to leak after the Lamp
Retainer is removed.
iv. Grasp the inside of the Quartz Tube and pull it out of the housing. Make sure the Sealing
Ring does not get lost during Quartz Tube removal.
v. Inspect the Sealing Ring for nicks or hardness and replace if necessary.
vii. Clean the Quartz Tube exterior with a mild solution of muriatic acid and water in a ratio
of four parts water to one part acid (4:1). DO NOT USE ABRASIVE CLEANERS as they can
scratch the high quality quartz glass.
CAUTION: Follow the directions for safe use and handling of muriatic acid on the acid bottle label.
Never add water to acid. Always add acid to water.
vii. After cleaning the Quartz Tube, wash it off with water and wipe dry with a soft towel. Inspect
the Quartz Tube for cracks and replace if cracks are found.
viii. Make sure the inside of the Quartz Tube is dry before replacing the UV Lamp(s).
NOTE: Damage caused by broken quartz tubes is not covered under the Mast3rPur System Limited
Warranty.
