Det-Tronics X3300 Protect-IR Multispectrum IR Flame Detector User Manual

Page 17

To maintain maximum sensitivity, the viewing windows
of the X3300 must be kept relatively clean. Refer to the
procedure below for instructions.

CLEANING PROCEDURE

CAUTION

Disable any extinguishing equipment that is
connected to the unit to prevent unwanted
actuation.

To clean the window and

oi plate, use Det-Tronics

window cleaner (part number 001680-001) and a soft
cloth or tissue and refer to the procedure below.

Disable any extinguishing equipment that is
connected to the unit.

Since the X3300 is less affected by contamination
than other detectors, removal of the

oi plate is

needed only under extreme conditions. In addition,
it is not necessary to achieve perfect cleanliness,
because IR is not significantly absorbed by slight
films of oil and/or salt. If a fault condition is still
indicated after cleaning, remove and clean the

plate using the procedure below.

Clean all three viewing windows and reflector
surfaces thoroughly using a clean cloth, cotton
swab or tissue and Det-Tronics window cleaning
solution. If a stronger solution is needed, isopropyl
alcohol may be used.

PLATE REMOVAL

Remove the

oi plate from the detector by loosening

the

oi plate knob.

Thoroughly clean the

oi plate reflective surfaces,

holding it by its edges to avoid leaving fingerprints
on the inside reflective surface.

Re-install the

oi plate. Ensure that the plate is flat

on the detector surface. Tighten the

oi plate knob

securely (40 oz/inches).

NOTE

If the

plate is removed, be sure to install the

original

plate.

plates are not interchangeable

and should not be mixed with

plates from other

detectors.

NOTE

If corrosive contaminants in the atmosphere cause
the

plate surface to deteriorate to the extent that

it is no longer possible to restore it to its original
condition, it must be replaced. Consult factory for

plate replacement procedure.
