IMPORTANT!
Low accumulator capacity
– When the accumulator only has capacity left for one
more lifting cycle, the control box will make an audible
sound, when using the hand control.
WARNING!
Risk of explosion
Old or faulty accumulators may generate an explosive
gas mixture during charging.
– The accumulator box is provided with vents to ensure
adequate ventilation of the box. Do not block or
cover the vents, as this may result in pressure built-up
and the risk of explosion.

Mounting the backup battery
1. Install the box, on the bed´s base frame, next to the control
unit B.
2. Connect the cable to the control unit.
Charging the batteries
1. Connect the control unit to the mains.
•
The control unit must be connected to the mains for
24 hours prior to first use.
•
Accumulators must be charged, at least, every 6 months
for maintenance purposes.
Preventive maintenance
Frequent, sudden discharges reduce the backup's life.
We recommend the accumulator be tested at least once a year.
Accumulators are not damaged by continuous connection to the
mains.
Exchanging the accumulators
•
Accumulators have to be exchanged after 4 years. Depending
on how the back up is used the exchange may have to take
place earlier.
•
Accumulators must be exchanged as sets.
•
Accumulators must be replaced with accumulators of the same
type or mechanically and electrically compatible accumulators
(12V - 1,2 Ah).
•
Accumulators, in a set, must have identical production codes.
Prior to insertion make sure that the accumulator set
is correctly connected according to the drawing (in the
accumulator box), and that none of the connections are
loose.
