Setup

Installing the Battery Pack

1. Align arms on top half of case with slots on either side of the battery pack housing. Ensure the back of the battery pack with the charging jack is on the same side as the belt clip.

2. Slide battery pack up until arms click into place.

3. Push each security screw into the battery pack housing and tighten.

4. Completely charge battery before use (see Charging the Battery Pack).

Charging the Battery Pack

For proper maintenance of battery packs, SKC offers a charger (see Accessories on page 22) that conditions the battery for optimum performance in 6 to 8.5 hours.

1. For optimum charge, ensure pump is not running.

2. Insert the charging plug into the sampler’s charging jack.

3. Charge battery pack completely before use.

Plug the SKC PowerFlex® charger cable into the jack on the back of the battery pack (see charger operating instructions).

After charging the battery pack, it is good practice to run the pump for approximately ﬁ ve minutes before calibrating. This ensures the battery is in more steady-state conditions and improves the agreement in pre and post-sampling calibrations.

• To comply with intrinsic safety regulations, do not charge or operate the pump from the charger in hazardous locations.

• Using a non-approved charger voids any warranty.

• Use of a repaired or rebuilt battery pack voids any warranty and the UL Listing for intrinsic safety.

• Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety and any warranty.

• Ensure proper orientation of charging cable before plugging it into the charging jack. Improper orientation/contact will short-circuit the battery and voids any warranty.

• Short-circuiting the battery pack will render it immediately inoperative.

• Failure to follow warnings and cautions voids any warranty.

The battery pack may be kept on the SKC-approved charger for an indeﬁ nite time.

Possible Displays During Sampling

Flow or Battery Fault Shutdown - If the pump is unable to compensate due to excessive back pressure or a low battery condition exists, the sampler will shut down and timing functions will pause. Either a battery-shaped icon or a ﬂ ow fault icon

) will display on the LCD depending on the cause of the

(



shutdown. Upon ﬂ ow fault, the pump will attempt to restart up to 5 times. To restart from ﬂ ow fault, correct the blockage and press the on/off button twice. Elapsed time display will reset to 0 when pump is restarted. If the battery icon is displayed, recharge the battery before sampling.

Displayed Elapsed Run Time - Elapsed run time is displayed continuously on the LCD. For elapsed times after 999 minutes, the display still shows elapsed time, but alternates displaying the first two digits of the elapsed time and the last three digits. For example, a pump that has run for 1,440 minutes would display ﬁ rst “01” and then “440.” The display maximum is 99 999, which is 99,999 minutes.

Sampling with Impingers

Place an in-line trap between the pump and the impinger. The impinger and trap can be mounted to the sampler using the accessory mounting screws (Figure 1, #8) or placed in a holster at the worker’s waist.

Impinger sampling requires an in-line trap (SKC Cat. No. 225-22 or 225-22-01) to prevent fumes from accidentally being drawn into the sampler. Single or dual impinger/ trap holders (SKC Cat. No. 225-2001 or 225-20-02) may be mounted directly to the face of the sampler using the accessory mounting screws.

Failure to use an appropriate in-line trap during impinger sampling voids any warranty.

Protect sample pump from weather when in use outdoors.

Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety and any warranty.

Setting or Verifying Flow Rate - Multiple Tube

When performing multiple-tube sampling using an adjustable low ﬂ ow holder (dual, tri, or quad), ensure the pump ﬂ ow rate is set at 1.5 L/min. The maximum ﬂ ow rate through any one tube is 500 ml/min*. Calculate the sum of all tube ﬂ ow rates. If the sum is ≤1000 ml/min, proceed with calibration and sampling without any further adjustment to the pump ﬂ ow rate. If the sum is >1000 ml/ min, set the pump ﬂ ow rate 15% higher than the sum of tube ﬂ ow rates.

* Back pressure across some sample tubes can be higher than average.

In these instances, the maximum ﬂ ow rate of 500 ml/min per tube may not be achieved.

Before use, allow pump to equilibrate after moving it from one temperature extreme to another.

Set pump ﬂ ow rate to 1.5 L/min. Connect a constant pressure controller (CPC) (Figure 2, page 10) to the pump intake (Figure 2, #1) using 1/4-inch Tygon tubing.

Using 1/4-inch tubing, connect the intake of a CPC (Figure 2, #3) to the outlet of a multiple-tube adjustable low ﬂ ow holder (Figure 3, #7).

Insert an opened sorbent tube into each rubber sleeve of the low ﬂ ow holder (Figure 3, #3 and 4) with the arrow on the tube pointing toward the holder.

If sampling with fewer tubes than number of ports, insert unopened sorbent tubes in the empty ports to seal them.

Connect CPC to pump

intake, holder to CPC,

and tube inlet to

calibrator.

Note the ﬂ ow rates speciﬁ ed by each sampling method and add them together. If the sum is ≤1000 ml/min, proceed to the next step. If the sum is >1000 ml/min, multiply the total tube ﬂ ow rate by 1.15 and set the pump for that ﬂ ow rate.

continued on page 14

cont’d

Connect a calibrator to the exposed end of a sorbent tube, loosen the screw on the appropriate port of the low ﬂ ow holder, and activate the pump by pressing the on/ off button.

Turn the brass ﬂ ow adjust screw (Figure 3, #2) on the low ﬂ ow holder until the desired ﬂ ow rate is achieved. Turn clockwise to decrease ﬂ ow.

Do not adjust the ﬂ ow on the pump. Adjust the ﬂ ow only by using the ﬂ ow adjust screw on the low ﬂ ow holder. Observe tube ﬂ ow rate on calibrator.

When the desired ﬂ ow is set on the initial tube, turn off the pump by pressing the on/off button. Remove the calibrator from the tube and connect to the exposed end of the next sorbent tube. Press the pump’s on/ off button and repeat the ﬂ ow adjust process until all tubes are ﬂ ow calibrated. Changing the ﬂ ow on one tube will not affect the ﬂ ow rate through the remaining tubes.

For tri and quad models, ﬁ rst rotate each anti-tamper cover (Figures 3 [on page 12] and 4) to expose the ﬂ ow adjust screw, then adjust until calibrator indicates the desired ﬂ ow.

Maintenance

Pump Inlet Filter

The AirChek 52 Sampler is ﬁ tted with a ﬁ lter/trap just below the pump intake. This prevents particles from being drawn into the pump mechanism. The ﬁ lter should be replaced periodically. Follow this procedure:

1. Grip the inlet hose barb (Figure 1, #4 on page 9) and unscrew it counterclockwise.

2. Holding the pump upside down, use a small

ﬂ athead screwdriver or tweezers to remove ﬁ lter.

3. Place a new ﬁ lter in the intake. Ensure the rubber gasket inside the inlet hose barb is still in place.

4. Screw the inlet hose barb back into place.

Replacing the Battery Pack

To enhance battery life, SKC ships battery packs separate from the pump (see Charging the Battery Pack on page 5). Once installed, completely charge the battery pack before operating the pump. It may be necessary to charge the battery a few times before maximum battery capacity is achieved.

1. Loosen two security screws on bottom of pump case and allow them to fall to the out position.

2. Pinch battery pack release arms and pull the bottom half of the pump case away from the top half.

3. Align arms on top half of case with slots on either side of the new battery pack housing. Ensure the back of the battery pack with the charging jack is on the same side as the belt clip.

4. Slide battery pack up until arms click into place.

5. Push each security screw into the battery pack housing and tighten.

For information on SKC pump battery packs,

visit http://www.skcinc.com/instructions/1756.pdf.

Battery Eliminator

The Battery Eliminator is an accessory that converts alternating current (AC) to direct current (DC) from which the pump can be operated for extended runs. The Battery Eliminator should be used in non-hazardous locations only. See page 22 for ordering.

To use the Battery Eliminator, the battery pack must be removed from the pump (see Maintenance, Replacing the Battery Pack). The Battery Eliminator is comprised of two pieces, (1) a wall cube that converts AC voltage to DC voltage and (2) a power adapter that reduces DC voltage. The wall cube ﬁ ts into a standard wall outlet and its plug end is inserted into the power adapter. The power adapter is ﬁ tted on the pump in place of the battery pack.

Use of the battery eliminator to power the pump voids the UL Listing for intrinsic safety.
