g) For a commercial battery charger that is intended to be permanently
installed and un-tampered with, the charger should be installed so that it is
not likely to be contacted by people.

The package should contain the following:
1) Pro Charge Ultra
2) Owners/Installation manual
3) Temperature Sensor
DAMAGE – If any parts are missing or damaged, or the unit has been damaged in shipping -
contact Sterling. Do not take it back to the place of purchase as we can offer a faster service.
DO NOT attempt to install or operate the unit if it has been damaged in any way.
MAINTENANCE
This unit is solid state software controlled and requires no constant
adjustments or attention, however, the following items should be checked:
1) On start up ensure the panel shows no fault LEDs.
2) On start up check the conditions of the fuses and ensure there is no
discolouration or corrosion round the fuse, also, check that the breaker will
manually trip and reset.
3) On start up check the fans cooling flow is not impeded by debris, keep
the area round the unit clear of items and dirt.
4) On Start up check for any traces of water / other liquids running down the
front of the unit or any evidence of this (water stains).
5) Do not use the charger, find the leak and fix the leak or remount the
charger to a safer place away from the water source.
6) Check the battery charger terminals and the battery terminals for
corrosion monthly, clean as required.
7) As per battery manufacturers' instructions check and top up the batteries
with distilled water, as required monthly. Do not use tap or bottled water as
this will destroy the batteries.
8) Check the wires for any burning or chaffing, monthly. This is where the
wires pass through bulkheads. Repair / replace as required.
9) When the charger is on, feel the temperature of the batteries, they should
not be noticeably hotter than the surrounding ambient temperature.
If the batteries are hot to the touch then they need major investigation,
check the charger voltage is within parameters. If it is then the batterys must
be checked as they are probably defective.
Never walk away from warm-hot batteries as there is a
major problem, switch the charger off.
