- What
power is consumed by the UV disinfection system?
- The size of the
UV system will determine the electrical power demand. Trojan UVMax
systems are rated from 25 - 102 watts of energy (similar to a standard
light bulb), which reflects the maximum power at lamp start-up. The
continuous energy consumption tends to be 75 - 80% of the rated power.
- Where
should I install the Trojan UVMax Disinfection System?
- The UV system
must be situated in-line after all other water treatment equipment,
as some of these may act as breeding grounds for pathogens.
- What
type of pre-treatment should be installed?
- Sediment filtration
(5 micron nominal) is the minimum pre-treatment prior to the UV system.
A carbon filter will remove organic compounds present in the water
that may or may not be visible to the eye. Organic compounds absorb
UV energy, which reduces the efficiency of the system. Carbon filters
can also improve water aesthetics by reducing unwanted taste and odour.
The required pre-treatment equipment is the final decision of the
Trojan distributor and water specialist.
- Do
the distribution lines need to be shocked?
- Yes. After installing
the UV system it is important to remove any contamination that may
already be present in the lines. Refer to the owner's manual for detailed
procedures.
- Should
I shut off the UV system when I am not using water?
- No. The Trojan
UVMax disinfection system is designed to operate continuously. If
the system is turned off it may be possible for bacteria and viruses
to migrate through the water chamber and contaminate the distribution
lines past the UV system. In addition, the life of the lamp and ballast
may be reduced as a result of frequent starting and stopping.
- Why
does the water get warm?
- Over long periods
of non-use, the water in the reaction chamber will become warm due
to the high operating temperature of the lamp. The Trojan UVMax systems
are designed to avoid overheating. The water chamber contains only
a small volume of water and will cool quickly once the faucet is opened.
- Does
the lamp's sleeve require cleaning?
- Yes. Iron and
other contaminants present in the water will precipitate onto the
outside of the lamp sleeve during normal operation. This is referred
to as fouling. Refer to the Owner's Manual for cleaning procedures.
- How
often should I clean the lamp's sleeve?
- Typically, cleaning
is required 3 - 4 times a year, but it is dependent on the quality
of the water. If the water entering the UV system is sufficiently
filtered, then cleaning may not be required as frequently. Ultraviolet
sensors, available on some models, are designed to notify the owner
when the intensity of the lamp has been reduced due to sleeve fouling
or lamp aging. It should be noted that the viewing window on the sensor
is made of quartz, which is also susceptible to fouling.
- How
are customers protected from power fluctuations?
- The new electronic
ballasts employed in all models of the Trojan UVMax are auto ranging,
meaning that they can accept a range of power voltages while still
delivering the correct current to the lamp. See model specifications
for details.
- How
can you protect customers from drinking untreated water when under
power outage conditions?
- There is an external
control relay (dry contact) located in the power supply of the D,
E, F and Pro Series units. This may be connected to a solenoid valve.
In the event of a power outage the valve will close making it impossible
for water to pass by untreated.
- What
happens to the elapsed time meter if the power goes off?
- The time meter
is operated by computer chips that keep a memory of the lamp's elapsed
time during power outages.
