- Page 12 Sampling with Impingers When using impingers, place an in-line trap between the pump and the impinger to protect the sam- pler from liquid or vapors. The impinger and trap can be mounted to the sampler using the accessory mounting screws (Figure 1, #12) or (cont’d) placed in a holster at the worker’s waist.

Page 18: Low Flow Multiple-Tube Applications
For a diagram of the pump, see Figure 1, page 9. Ensure pump is not running. Charge the battery by connecting the charger plug to the sampler charging jack (Figure 1, #22). Ensure that the battery is fully charged before sampling. Do not charge or operate pump from charger in hazardous locations. Charger and battery Charge in fresh air only. pack connected Use only an SKC-approved charger designated for this model to ensure reliable performance and to maintain the SKC warranty. Ensure proper orientation of charging cable before plugging it into the charging jack. Improper orientation/contact will short- circuit the battery. Short-circuiting the battery pack will render it immediately inoperative. - Page 19 Setting or Verifying Flow Rate If performing multiple-tube sampling using an adjustable low flow holder (dual, tri, or quad), the flow rate of the pump must be greater than the sum of the flow rates through the tubes; the flow rate through any one tube cannot exceed 500 ml/min and maximum total combined flow is 1350 ml/min.

(not shown) Beltclip Back of pump with battery pack sliding out Case grooves Case screw Use of a repaired or rebuilt battery pack voids the SKC warranty and MSHA approval. Do not charge or operate the pump with charger in hazardous loca- tions! Charge in clean air only. Use only an SKC-approved charger and battery pack designed for the MSHA-approved Universal Sample Pump to ensure reliable per- formance and to maintain the SKC warranty and MSHA approval. Use of any device to power the pump other than the approved bat- tery pack voids MSHA approval. MSHA approved for use with SKC Part No. P22434 (4.8 V battery pack) only.
