CLEANING THE MODULE
To clean the outside surface, use a damp cloth or sponge. Do not use solvents or abrasive
cleaners and do not open the enclosure while it is wet (it is an electrical device).
FUSE REPLACEMENT
The fuse on the power supply board of the TTDM-128 and TTSIM units is a 200-mA, 250-
V, quick-acting microfuse. It has an F1 rating, characteristic code F (quick-acting). Use no
other type of fuse or the TTDM could be damaged or could fail to perform properly. One
spare fuse is provided in the TTDM (see feature 15 on page 16).
ROUTINE MAINTENANCE
It is recommended that the TraceTek system be thoroughly checked twice a year. Such
a check will identify conditions that adversely affect the leak-locating capability of the
system. More frequent checks may be required if the sensing cable is repeatedly exposed
to leaks, or may be exposed to abuse due to construction or repair work. Contact your
local Raychem TraceTek representative for further information on service support.
STORAGE AND HANDLING OF SENSING CABLE
Despite their rugged construction, TraceTek sensing cables must be handled in a manner
appropriate for a sensing device or they may be damaged and require replacement.
Therefore, you should follow some basic rules for storing and handling all TraceTek
sensing cables:
§
Store spare cable in its original container in a clean, dry place until ready for
installation.
§
Schedule cable installation after all mechanical, plumbing, and electrical work has
been completed.
§
Clean the area where the cable is to be installed, and remove any obvious debris or
other sources of contamination.
§
Do not solder or weld near the cable without providing protection from heat, solder
flux, or weld splatter.
§
Do not drop tools or floor tile on the cable; sharp or heavy objects may damage the
cable.
§
Avoid walking or stepping on the cable. Provide shielding (for example, a half shell of
plastic pipe) where additional protection is necessary.
§
Do not use tape to secure sensing cable (some tapes and adhesives absorb moisture)
or use solvents that could eventually cause an alarm.
§
Do not drag sensing cable through contaminants (such as pipe dope, PVC cement,
solvents, oil, or dirt).
