7.0 Maintenance
7.1 General Maintenance
Once correctly installed, the unit requires very little maintenance other than regular sensitivity
checks and cleaning of the lenses. General Monitors recommends that a schedule be
established and followed.
WARNING:
Disconnect or inhibit external devices, such as automatic extinguishing or fire
suppression systems before performing any maintenance.
NOTE
:
The removal of particulate matter and any film buildup on the windows and light rods is
necessary to ensure proper sensitivity of the system. It is recommended that the
window and light rods be cleaned at least every 30 days or more often if the detector is
located in a particularly dirty environment.
During routine maintenance of the equipment, if the base plate is removed, the flame path
should be replenished with grease compound.
European Union (EU) Approved Applications
: The following grease compound is recommended
for use: High Vacuum Grease (or equivalent), as a jointing compound on flameproof electrical
enclosures. This is available from General Monitors Ireland.
The viton o-ring gasket should also be lubricated with Castrol EP (P/N 916-062) or High
Vacuum (916-078) grease available from General Monitors should it become dry.
The removal of dust and film build-up on the windows is necessary to ensure proper sensitivity
of the system. Windows may be cleaned periodically, to avoid a COPM fault being triggered by
build-up, dirt or debris.
7.2 Cleaning the Lenses/Light Rods
NOTE
:
DO NOT USE A COMMERCIAL GLASS CLEANER OTHER THAN "INDUSTRIAL
STRENGTH WINDEX
®
with Ammonia D”. The lenses are not glass. The UV lens
material is quartz and the IR lens material is sapphire. The cleaning solution should be
General Monitors’ P/N 10272-1 ("Industrial Strength Windex
®
with Ammonia D").
A clean, soft, lint-free cloth, tissue or cotton swab should be used to apply the cleaning
solution. Do not touch the lenses or light rods with fingers.
1. Wet the window with the cleaning solution.
2. Rub with a dry, unsoiled cloth until the window is clean.
3. Let the window dry completely.
4. Repeat steps 1, 2 and 3 for the light rods (Figure 22). Take care only to clean the non-
coated (non - aluminum) areas of the light rods.
