Installing and Charging the Battery
Install. The AirChek 20 pump (Figure 1) is supplied without battery Cat.
No. P920201 installed. Install the battery as follows:
1. Unfasten the six casing screws (three on each side
of the case, see Figure 1) using supplied Pozidriv
size PZ1 screwdriver. Lift off black casing cover.
2. Remove the two protective covers from the battery
terminals and place battery in rear compartment of
pump case as shown in Figure 2. Ensure that equal
gaps are left between ends of battery and sides of
case to allow for case screws to be screwed in fully
without damaging battery.
3. Connect red battery cable from pump control PCB
to red '+' terminal on battery, and black battery cable
to black '-' terminal on battery.
4. Reinstall black casing cover, securing it with the six screws
using Pozidriv size PZ1 screwdriver.
Charge. Before first use, the battery should be fully charged, ideally overnight.
AirChek 20 must only be charged using SKC Battery Charger Cat. No. 920-210.
The battery charger can only be used to charge the battery when the pump is not running, and not when the pump is
•
running to extend pump run time.
• AirChek 20 can be powered by AC Adapter Cat. No. 920-211 suitable for 100-240 V or by an external high capacity
12V lead-acid battery (not SKC supplied) using external Battery Cable Cat. No. 920-212. It is recommended that
these options be used in conjunction with internal battery Cat. No. P920201 to retain the pump program and run time
data when external power supplies are disconnected.
1. Unscrew dust cap from charging/power socket on pump (see Figure 1) and connect output connector from charger to
pump socket. Screw charging connector into socket to prevent it from detaching while charging.
2. Plug charger into a 100 to 240 V wall outlet. LED indicator on charger will illuminate amber to indicate that charger is
charging at full power.
