10.0 MAINTENANCE & REPAIR GUIDELINES, REPLACEMENT PARTS
1. Maintenance: This Gas Detection Monitor requires evaluation every thirty (30) days to ensure
accuracy. The Monitor should be checked for accuracy by applying a known concentration of the
target gas that exceeds the programmed alarm levels. The displayed gas value will stabilize as the
gas fills the calibration chamber within the sensor head. When the programmed alarm levels are
breached, the alarm output for that level would be activated subsequently to the programmed alarm
delay duration. The displayed target gas value should match that of the concentration of test gas.
Any warning or control devices connected to the alarm outputs should remain connected during this
test to ensure proper operation of the entire gas detection system. Replace any inoperative or
questionable parts immediately. This gas detection monitor requires calibration every ninety (90)
days to ensure accuracy and to correct sensor drift. The gas detection “cell” located within the sensor
housing is in most cases, a consumable part with an expected life. The cell’s output decreases slowly
as it nears the end of its expected life. The rate at which the output decreases depends greatly on the
concentration and presence of target gas. This must be corrected by calibrating the monitor often to
ensure an accurate reading and dependable alarming and control of connected devices. Conspec
recommends that no modifications be made to this monitor without first consulting Conspec
Technical Services. Modifying this equipment without consulting the factory could result in unsafe
operation and/or unsafe atmospheric conditions. Modifying this equipment will void any warranty
authorized by Conspec Controls Inc.
2. Repair: Any monitor found to be defective or questionable should be returned to Conspec Controls
for evaluation and repair. Conspec requires any returned equipment to first be issued a Return
Authorization Number (R.A.#) by calling Conspec at (800) 487-8450 Mon.-Fri. 8am-5pm est.
Conspec also offers on-site Repair and Start-up service for Conspec Gas Detection Equipment.
3. Replacement Parts: Damaged or questionable parts should be replaced immediately upon
detection. Damaged or inoperative parts could contribute to hazardous and/or unsafe conditions. Any
consumable parts should be replaced if the reliability is questionable or within the part’s specific
expected life. Consumable parts include any filters, pump motors, sensors….etc.
