2. WATER CONNECTIONS
Important:
before making the connections, make sure that the
unit is disconnected from the mains.
CAUTION:
for the Australian market and to comply with
Watermark requirements, a watermarked approved dual check valve shall
be installed in the supply line to the humidifier when connected to
potable water. Should on the other hand the humidifier be fed with
treated water from a Carel reverse osmosis system connected to potable
water, the dual check valve shall be installed in the supply line to the
reverse osmosis system.

Notes for connection between cabinet and rack:
1.
Mount the pipes with u-bolts or clamps with steps of about 30 cm.
(not supplied by Carel).
2.
In the case of two racks or one two-step rack, mount the pipes
parallel, avoiding any contact.
3.
In laying the pipes, avoid conditions that could cause the water to
stagnate with the system is halted.
Connect an expansion tank (not supplied by CAREL SpA) with a capacity
of at least 5 litres, upstream from the cabinet in order to prevent water
hammering which can damage the system.
The connection to the cabinet must be performed using flexible piping.
