IMPORTANT SAFETY INSTRUCTIONS:
READ COMPLETELY BEFORE PROCEEDING.
When using this electrical equipment, basic safety precautions should always be followed,
including the following:
WARNING:
• Follow all applicable electrical codes.
•T
urn off power at main source before making any electrical connections or servicing the unit.
•T
o reduce the risk of electric shock, injury or death disconnect unit from power supply
HOW TO DISCONNECT THE ELECTRICAL
POWER TO A TRIDENT SERIES 2 UV UNIT
The Trident units are made in both 120V and 230V. The
method for disconnecting the electrical power to the unit is
somewhat dependent on how the unit was installed. There
are three possibilities.
1.The unit is a 120V and its power cord is plugged
into a 120V receptacle. To disconnect power, simply
unplug the power cord from the receptacle
2.The unit has been wired to the power source by the
installer.
A. To disconnect power, IF THE UNIT IS WIRED TO
A DEDICATED ELECTRICAL CIRCUIT, simply
identify the breaker in the supply panel serving the UV
unit and turn off that breaker. If unsure which breaker
is serving the UV unit, switch breakers on/off until
the UV unit lamps go dark. Note: If any other piece of
pool equipment goes off with the UV unit, the UV unit
is not on a dedicated electrical circuit, so you must
proceed to the following steps noted in step B.
B. To disconnect power, IF THE UNIT IS WIRED TO
A SHARED ELECTRICAL CIRCUIT, disconnecting
electrical power to the unit is accomplished as
follows:
1. TURN OFF the shared electrical circuit
breaker. The UV lamps will turn off when you
have switched off the shared breaker. YOU
RISK SERIOUS INJURY OR DEATH
FROM ELECTRICAL SHOCK IF YOU
DO NOT TURN OFF THE SHARED
ELECTRICAL CIRCUIT BREAKER
BEFORE PROCEEDING FURTHER.
2. R
emove the round bonnet on the top of the
UV unit, using a Phillips screwdriver to remove
the three screws holding the bonnet in place.
Figure 1.
3. O
n the black mounting plate, locate the item
marked “Pressure Switch” Figure 2.
4. H
old the pressure switch firmly. Remove the
connector from the pressure switch as shown in
the picture. Pull one of the two wires attached
to the Pressure Switch off. The electrical power
to the UV unit is now off. This is the easiest way
to accomplish interrupting the electrical power
to hard wired units. Figure 3.
5. A
s an alternate, after the breaker serving the
UV unit is turned off, the power can also be
disrupted by unplugging the ballast(s) white
plugs from the white receptacles marked on the
black mounting plate as “Ballast Plug 1” and
“Ballast Plug 2”. If two ballasts are present, both
ballasts must be unplugged if this method to
disconnect the electrical is used. Figure 4 & 5.
6. S
et the bonnet back on the top of the UV
housing and secure with the screws.
7. T
URN THE BREAKER BACK ON and power
serving the second piece of equipment on the
same circuit will be restored. Check to be sure
the UV unit does not illuminate.

Regardless of how you elect to disconnect the electrical
power, this process will take only take between 1-3
minutes to accomplish. You will be contacted again before
long regarding the next step.
