Operating & Maintenance Instructions - Sterilight Silver SQ-PA Owner's Manual

PLEASE NOTE: As the Silver "PLUS" systems include a 254nm UV intensity
monitor, it should be noted that the introduction of the bleach solution
required for disinfection WILL trigger a temporary low UV condition. This is
due to the fact that the bleach physically "clouds" the raw water. Once the
bleach runs through the system, the alarm condition will return to normal.
During this sanitization process, the audible alarm condition on the Silver
"PLUS" controller can be temporarily deferred by pressing the "RESET"
switch for 5 seconds. By doing this, the audible alarm will be silenced and
the solenoid relay will close (AC power will be provided to the normally
closed (NC) solenoid, allowing water to pass through the system). The
system will display
for 12 hours unless the system is manually reset as outlined on page 10 of
this manual.
OPERATION
• Always disconnect power before performing any work on the
disinfection system.
• Regularly inspect your disinfection system to ensure that the
system is operational.
• Replace the UV lamp annually (or biennially if seasonal home use)
to ensure maximum disinfection.
• Always drain the reactor chamber when closing a seasonal home
or leaving the unit in an area subject to freezing temperatures.
O & M
PERATING
Caution: PRIOR TO PERFORMING ANY WORK ON THE
DISINFECTION SYSTEM, ALWAYS DISCONNECT THE POWER
SUPPLY FIRST.
UV Lamp Replacement / Cleaning:
1. To replace the lamp, there is NO need to disconnect the
system from the water supply, nor to drain the water from
the reactor chamber. Lamp replacement is a quick and
simple procedure requiring no special tools. The UV lamp
must be replaced after 9,000 hours of continuous operation
(approximately one year) in order to ensure adequate
disinfection.
2. Disconnect main power source and allow the unit to power
down. Remove the lamp connector by sliding the
metal retaining ring (Figure 2A) away from the body of the
connector. Remove connector and lamp from the reactor
chamber. Separate the lamp from the connector (Figure 2B).
Do not twist the lamp from the connector, simply slide the
two apart. Avoid touching the lamp on the glass portion.
Handling the lamp at the ceramic ends is acceptable,
however if you must touch the lamp glass, please use gloves,
or a soft cloth. Fully remove the lamp from the reactor
chamber being careful not to angle the lamp as it is removed
from the chamber. If the lamp is removed on an angle,
pressure will be applied on the inside of the quartz sleeve,
causing the sleeve to fracture
on the controller LED. This condition will remain
