Installaon
1. Open the package with care to avoid damage to the product. Check the device, tubing,
and garment are in good condition and undamaged prior to use.
2. Install the device on a at and stable surface.
* To avoid the air ow of the CTC-7 from being interrupted, place the device in an
area with 30cm clearance around it.
3. Open the water bottle cap located on the rear side of
the device, ll the water bottle with distilled water,
and screw the cap back on rmly.
• When adding distilled water, use a jug with a sharp
spout.
• Check the water level indicator located on the rear
side of the device.
• The maximum volume of distilled water is 250mL.
Once operang, the device needs to be topped
up with water as the inial water moves from the
device to the garment.
4. Find the water socket located on the side of the
device and connect the garment water tubing to
this until you hear a “click” sound.
• When the device is used without properly
connecting the tubing there is a risk of water
leakage.
5. After you connect the water socket, connect the air
socket by pushing the tubing until you hear a “click”
sound.
6. Check whether or not the pipe attached to the wrap
is twisted. (The pipe is only in the re-usable wrap.
Disposable wrap do not have drain pipes.)
• When the pipe is twisted 90 degrees, the distilled
water will spill.
7. Find the power cord socket located on the side of
the device, and connect the cord. Then, connect the
device to a power outlet.
• Install this device in an environment where
the power cord can be easily connected and
disconnected.
