3. The water purifier should be mounted horizontally on a flat dry surface. Secure the water purifier using the mounting
holes in the ballast housing or with the optional wall mounting kit. The purifier should not be solely supported by its
plumbing connections.
4. The water purifier must be connected to the cold water line only.
5. It is recommended that a 5-micron sediment filter be installed, in line, prior to the water purifier. The sediment filter will
stop or trap any particulates from entering the water purifier. Particulates may cause damage to the quartz sleeve, as well
as interfere with the purifier’s ability to disinfect the water. The sediment filter may also help to reduce the amount of
routine cleaning of the quartz sleeve.
6. Shut off valves should be installed on both the inlet and outlet sides of the water purifier. The use of bypass valves is
not recommended. The shut off valves allow the purifier to be isolated from the water supply, which is required when
removing the quartz sleeve.
7. Unions should be installed on both the inlet and outlet of the water purifier; this will allow easy removal of the water
purifier from the plumbing, if required. Apply Teflon® tape to threads of inlet and outlet ports to ensure a tight seal.
8. When all plumbing connections are complete, allow water to enter the water purifier at a low flow rate, until the purifier
is pressurized. With the purifier pressurized, it should be checked for leaks. Once it is determined that there are no leaks,
the inlet valve can be fully opened.
9. For Models with lamps packed separately, install lamp following the steps in “Lamp Installation or Replacement” section.
CAUTION: Lamp and quartz sleeve are easily damaged. Exercise care when installing lamp.
10. Once the plumbing hook ups are made, it is a good practice to disinfect the “downstream” plumbing between the purifier
and point of use. This is done by introducing chlorine into the purifier chamber, a 100-ppm solution of chlorine is
suggested. With the chlorine in the purifier chamber, turn the ultraviolet purifier on. Open the “downstream” outlet until a
chlorine odor is noticed. Close the outlet and allow the chlorine to remain in the plumbing for three (3) hours. Flush the
plumbing with ultraviolet purified water; allow the water to run for several minutes before use. This will allow the
chlorine to be flushed from the pipes.

NSTALLATION
1. Remove water purifier from shipping carton. Inspect water purifier, power cord and plug for damage. Do not operate if
there is any damage to the purifier, power cord or plug. Models MP13A through MP22A are shipped with the lamps
already installed, while the MP36C and MP49C lamps are packed separately. Keep the lamp aside for installation once
the purifier has been properly installed.
2. Units occasionally experience damage in shipment due to the fragility of the quartz sleeve. It is therefore recommended
to inspect the water purifier for damage to the quartz sleeve after it has been removed from the shipping carton. Each end
of the unit as well as the inlet and outlet should be viewed to see if the quartz sleeve has experienced damage. If the
quartz sleeve shows signs of damage it should be replaced before the purifier is pressurized. See “Quartz Sleeve
Cleaning or Replacement” in the “Maintenance” section for the proper method of replacing the quartz sleeve in your
water purifier.
