SYSTEM START-UP
Do not connect the
pressure switch until
the pool is operational!
NOTICE
PRESSURE SWITCH
The Ultra UV2 unit is equipped with pressure switch
that does not allow the UV lamp(s) inside the unit to
light unless there is at least
5 PSI (0.35 BAR)
inside
the Ultra UV2 reactor chamber. This will ensure that
the lamp(s) will illuminate when the Ultra UV2 unit
has water flowing through the reactor. The lamps will
only illuminate when the pressure switch senses a
minimum starting pressure of 5 psi (0.35 bar).
CONNECTING PRESSURE SWITCH
Disconnect power to the Ultra UV2 unit. Remove the
cover (Fig. 5) and locate the pressure switch and the
loose lead with the female spade connector (Fig. 6).
Connect the female spade connector to the male top
spade connector on the pressure switch (Fig. 7).
Replace the cover and restore power to the unit. Turn
on the pump and the flow should activate the switch.
The unit should be on and the lamps illuminated. Look
at the “Glow Ring” in the center of the unit to check
that all lamps are lit. If the lamps are not on, first verify
the unit is operating at 5 psi or more, then refer to the
troubleshooting section of this manual on page 17.
The filter gauge DOES
NOT indicate the
pressure in the UV unit
NOTICE
Do not look directly
at the lamps. Serious
injury will occur.
WARNING
If the Ultra UV2 does not illuminate check the following:
1. Adjust the system valves so there is flow through the
Ultra UV2 unit and not diverted to other devices.
2. The pump is producing enough pressure. If you have
a variable speed pump verify you are set at a hig
h
enough speed to produce enough pressure to tur
n
on the lamps
.
WATER CHEMICAL BALANCE
If you have installed your Ultra UV2 unit on any water
vessel other than fish ponds or ponds with live plants,
it is important that you check and adjust the chemical
balance of the water. The Ultra UV2 unit dramatically
reduces the need for chemical sanitizers, but a
minimum sanitizer residual must be maintained.

UPGRADING THE OUTPUT OF THE
ULTRA UV2 UNIT
One of the exclusive features of the Ultra
UV2 system is the ability to increase the
UV output of the unit by adding additional
lamps. Up to two additional lamps can
be added to a single lamp system. This is
accomplished easily by adding lamps and
or adding additional ballasts and lamps.
Plumbing modifications might be required
for certain lamp upgrades
