• Keep the device out of extremely high or low temperature locations.

• Do not expose the battery to liquid.

• Do not use the device if you notice any damage to the battery.

• Do not disassemble or modify the battery.

• Handle and dispose of the battery per local regulations.

• If the recharging operation fails to complete, even when the specified recharging

time has elapsed, immediately stop further recharging.

• Do not leave the battery unattended while charging.

• Unplug the charger when the battery is fully charged.

• Improper use or disposal of lithium ion batteries can cause a fire.

• High RF environments may cause a false alarm.

WARNING

This symbol alerts the user to the presence of important operating and

maintenance (servicing) instructions.

WARNING

Exposure to high concentrations of CO2 or refrigerants is dangerous and can

be life-threatening.

The instrument is not for use in toxic or hazardous environments. It is not a personal

protection or life-saving device. Always exercise extreme caution in potentially toxic or

hazardous environments.

WARNING

This product is not intrinsically safe and should not be used in the presence of

explosive fumes, explosive dust, or other explosive chemicals. Use in an

environment with flammable refrigerant concentration approaching the LEL

could cause an explosion or fire resulting in serious injury, death, or damage

to property.

3 The upper leak detection limit is not specified by INFICON as there is no upper limit

to the size of the leak the detector is able to detect.

4As no 50 g/yr. leak standard was available during testing, a 32 g/yr leak standard was

substituted.

SAE Applications SAE standards J2791 (R-134a) and J2913 (R-1234yf) specify sensitivity to the

following leak sizes for the corresponding settings below. Super sensitivity is more

sensitive than what is required by SAE for leak checking in a clean environment (free

of background refrigerant). If leak checking in a contaminated environment (high

background refrigerant), switch to Super sensitivity.

leak test procedure

Always leak test with the engine off.

Charge the system with sufficient refrigerant to have a gauge pressure of at

least 340 kPa (50 psi) with the system off. At ambient temperatures below 15 °C

(59 °F) leaks may not be measurable because the pressure may not be

reached.

Visually trace the entire refrigerant system, and look for signs of air conditioning

lubricant leakage, damage and corrosion on all lines, hoses and components.

Check each questionable area with the detector probe, as well as all fittings,

hose-to-line couplings, refrigerant controls, service valves with caps in place,

brazed or welded areas, and areas around attachment points and hold-downs

on lines and components. If looking for an apparently larger leak, check first at

the medium (7 g/year) or low (14 g/year) sensitivity setting.

Always follow the refrigerant system around in a continuous path so that no

areas of potential leaks are missed. If a leak is found, always continue to test

the remainder of the system.

Recheck the service valves with the caps removed. Blow shop air over the

service valve to clear the immediate area. Check with a detector on the medium

sensitivity setting (7 g/year).

Move the detector at a rate of no more than 75 mm/s (3 in./s) and as close as

possible to 9.5 mm (3/8 in.) from the surface, completely encircling each test

position (switch, sensor, refrigerant tubing connection, etc.).

074-708-P16B D-TEK Stratus Operating Manual 9 / 405

Slower movement and closer approach of the probe normally improves the

likelihood of finding a leak. However, detectors made to meet this standard are

based on air sampling from the 9.5 mm (3/8 in) distance. A retest is advisable

when a leak appears to be found at the most sensitive settings, particularly if the

probe was in a static position on a joint, or making physical contact with a joint,

as it was moving. Repeat with a moving probe test at that location, taking care

to maintain the small gap (9.5 mm or 3/8 in.) to confirm that the leak is of

repairable size. Checking with the medium sensitivity setting (7 g/year) after

finding an apparent leak with the high sensitivity setting (4 g/year) also may be

helpful.
