Notes and Cautions

• Do not operate pump from or charge pump with charging cradle in hazardous locations.

• Power off pump before removing battery to avoid loss of time, date, and other settings.

• Use only the SKC-approved battery pack (Cat. No. P75718) and charging cradle (Cat. No. 220-800 or 220-900) for pump. Use
of an unapproved battery and/or charging cradle could damage the pump and will void any warranty.

• Tampering with the battery pack (opening, disassembling, short circuiting, crushing, or exposing the battery pack to fi re or
temperatures in excess of 212 F [100 C]) voids any warranty.

• User may replace external components such as the inlet fi lter, battery, protective screen cover, and/or belt clip. Service must
be done by SKC to maintain performance and IS rating. Warranty is void if pumping compartment is opened by user.

• Failure to follow warnings, notes, and cautions voids any warranty.

• WARNING: Substitution of components may impair intrinsic safety. ADVERTISSEMENT: La substitution de composants peut
compromettre la Sécurité Intrinsèque.

• CAUTION: The battery used in this device may present a risk of fi re or explosion when heated above 212 F (100 C) or incinerated.
Replace battery with SKC Unlisted Component Battery Pack model P75718 only. Use of another battery may present a risk of
fi re or explosion.

• Model 220-5000TC: Exia – Intrinsically safe/ Sécurité Intrinsèque

• Warning: To prevent ignition of a hazardous atmosphere, batteries must only be changed [removed and replaced] in an area
known to be non-hazardous. ADVERTISSEMENT: Afi n de prévenir l’infl ammation d’atmosphères dangereuses, ne changer les

Performing a Full Calibration (Reset Compensation System)

CalChek Full Calibration, also known as CalChek Full or Multiple-point Calibration, is used to calibrate the pump compensation
system across the range of operational fl ows following maintenance/repair. Full Calibration requires a chek-mate Calibrator with CalChek
(Cat. No. 375-0550N), Standard Charging Cradle (Cat. No. 220-800) or Charging e-Cradle (Cat. No. 220-900), CalChek Communication
Cable (Cat. No. 375-200), and Pulsation Dampener (Cat. No. 375-100). CalChek Full Calibration is performed without a sampling medium
in line; the Pulsation Dampener is used in place of the sampling medium. See Figure 13.

• Allow pump to equilibrate after moving it from one temperature extreme to another.

• Charge pump battery completely before CalChek Full Calibration.
