Maintenance
The DTEX system essentially requires no in the
field maintenance.
There are NO field serviceable components.
ALL service and re-calibration must be per -
formed by the factory.
Please note the following items to insure trouble
free service:
1. The unit requires annual re-calibration .
The scheduled re-calibration date is displayed
at power up and is also available by pressing
the Info key at the main display screen. Refer
to Section 12 for re-calibration information. We
offer a 1 year recalibration or a 2 year recalibra -
tion.
2. Recharge of the system battery will be re-
quired periodically. Battery condition is shown at
the main display screen.
3. Do not expose the unit to debris - Damage
Will Result! Keep lid closed and gas inlet capped
when not in use. Keep air intake and sniff
chamber clean.
4. Clean the unit with a damp cloth . Avoid
cleaners which could damage the display/key-
pad and possibly leave a residual odor.
5. Properly vent the unit after testing. Failure
to vent gas from the unit after testing may lead to
odor saturation of internal components.
6. Each instrument has its own unique
background smell, just as each room has a
smell peculiar to it. Every 30 days perform an
exhaust background evaluation. Without con-
necting gas to the inlet, power on the unit, open
the flow valve fully and press P on the keypad to
purge the unit. Purge for 2 minutes before clos-
ing valve and pressing Enter key to conclude the
purge procedure. If after 2 minutes, smell per-
sists over and above normal background send
unit to be serviced.
