Operating The Charger - Guest 2722-B Owner's Manual

Mounting the Charger
1. Use corrosion resistant # 10 bolts, backed by a flat washer, and secured to the
mounting surface with a split-ring washer.
2. Hold the charger to the mounting surface and mark the holes.
3. Remove the charger and drill the mounting holes.
4. Align the charger and assemble the mounting hardware. Secure.
Making Connections
DANGER
Before working on electrical equipment, first determine there is no live AC
power! Double-check power connections and all battery terminations.
Check polarity of battery posts. The POSITIVE (POS., P, +) battery post usually has
a larger diameter than the NEGATIVE (NEG., N, -) post.
Refer to Connections at a glance for proper DC and AC terminations.

4. OPERATING THE CHARGER

When this charger senses a drop in battery voltage, it automatically increases its
output to re-charge the battery. When the low battery returns to full charge, the 2722-
B maintains very small current flow to keep the batteries fully charged and ready for
use without overcharging. The total 30-amp output of this charger is divided between
the two outputs.
The Guest ChargePro 2722-B battery charger is fully automatic, requires no
maintenance, and can be left unattended. However, the electrolyte (battery acid) in
lead acid batteries can gradually evaporate, particularly in warm climates. For this
reason, check the levels in your batteries once a month as a part of your normal
maintenance routine.
Timer Feature
The timer allows the charger to stay in the absorption mode for approximately 2 hrs.
Once it has timed out, it brings the output voltage down from 14.50VDC (Absorption
voltage) to 13.30VDC (Float voltage) while still maintaining output current. This keeps
the batteries from boiling while maintaining the current needed for dc loads.
