Maintenance and safety related inspection
HICO-VARIOTHERM 550
56
8.1.1 Unit
•
Periodically
check the ventilation openings on the side, bottom
and back of the unit regularly for contamination.
•
Dust deposits in the unit reduce the performance of the
system. Have the contamination on the inside of the unit
removed by a service technician (customer service, medical
engineering). Do not open the unit yourself.
•
Ensure the maintenance and safety check intervals are
maintained by the customer service or medical engineering.
8.1.2 Water tank
Replace the sterile filtered tap water in the water tank at least
every 2 weeks (described in chapter 7.2.1) as follows:
•
Disconnect unit from the mains.
•
Support container (bucket, baisin etc.) or place the unit onto a
draining device (e.g. rinsing tank).
•
Unscrew the cap of the water filler neck (5), e.g. with a coin.
•
Take the water drain hose and place it on one of the front
hose couplings (9).
•
Tilt the unit forwards and drain the water through the water
drain hose until it is emptied completely.
•
Remove the water drain hose from the front hose coupling and
place it aside.
•
Clean and disinfect the water circuit as described in chapter
7.2.1
•
Refill the unit with sterile filtered tap water to which a
germicidal agent has been added as described in chapter
4.3.1. The max. filling capacity of the unit tank is approx.1 litre.
8.1.3 Hose couplings
The seal rings (O-rings) on all couplings are subject of aging and
become dry and brittle. You should therefore cover the rings with
a thin film of silicone paste or vaseline every 6 months.
