toluene and other chemicals besides or above the
machine.
•Make sure the machine isn’t placed on the cable, and
all electrical cables are secured to avoid injury to the
user or damage to the machine/ cable.
•Don’t operate or repair the machine with wet hands.
•Under no condition should users repair the machine
by themselves. Only professionals are authorised
to repair the machine, it may result in personal injury
or more serious damage to the equipment.
•Do not wash the machine directly with water or
cleanser. Clean with water or mild detergent applied
with a cloth.
•To avoiding machine breakdown or any danger, it is
prohibited to insert objects into the air outlet.
•Users should not modify or repair the power wire.

Installation Location
The installation site should:
•provide sufficient installation and maintenance space,
•have no barrier to the inlet,
•be positioned so the outlet will avoid strong wind,
•be dry and well ventilated,
•have even support which is strong enough to bear the
weight of the machine,
•allow the machine to be installed horizontally, creating
no extra noise and vibration,
•be positioned where running noise and discharge air
will not cause disturbance to any neighboring property,
•not be exposed to flammable air leakage,
•have easy access for piping and electrical connection.
Don’t install the system at the following places, which may
cause system failure:
•places with mineral oil like cutting machine oil,
•places with salty air,
•places with corrosive gas, such as sulfur.
•places with fluctuating power supply and voltage,
•vehicles or cabins,
•places such as kitchens where there is significant oil,
•places with strong electromagnetic waves,
•places with flammable gas and materials,
•places with acidic or alkaline gas,
•hazardous areas
Installation Cautions
Before Installation
•Select an appropriate method of transportation,
•Keep in the original packaging during transportation.
•If the machine is installed on a metal base of the
construction, the electrical insulation must be done
strictly according to the technical standards of
electrical equipment.
Installation Clearance
Reserve enough clearance for maintenance. Refer to
figure 5 below.

Drainpipe Installation
Connect the soft pipe to the drainpipe connector (1/2”)
•Gradient should be over 1/100,
•To avoid condensation on the surface of the
drainpipe, the drainpipe should be thermal insulated.
Most of the wiring has been completed before leaving the
factory, an installer is only needed to connect L, N and
Earth wires to feed the system, and to connect the
controller and sensors box internet wires to the PCB.
The internet wires have no sequence, length around 13 to
15 meters. Modbus connector P+ and N- should only be
applied when the project requires central control.

Power Cord Requirement
•It is a Class I appliance, be sure to make a reliable
grounding.
•The yellow-green wire is the grounding wire. It must
not be used for other purposes and cannot be cut. To
prevent the risk of electric shock do not use self-
tapping screws.
•Grounding resistance should be in line with the
national standard requirement of GB17790.
•User must provide a reliable grounding power supply.
Please do not connect grounding wire to places like
water pipes, gas canisters, drain outlets and other
unreliable places recognised by professionals.
•Set an appropriate indoor temperature. The indoor
temperature should not be set too high or too low.
The recommended temperature for cooling is
26-28deg.C, and 18-23deg.C for heating to make
most people feel comfortable.
•Windows and doors should be closed, otherwise, it
will affect the effectiveness of air conditioning.
•Equipment like TVs, radios etc. should be at least
one meter away from the machine, otherwise, they
will interfere with the image and make noise.
•The power of the machine should be shut down if it
is not used for a long time.
•To protect the machine, the power should be
connected for 24 hours before it is used.
•If it is shut down in winter, please clean the machine
and dry it. To protect from dust, please cover the
machine, open the outlet valve to drain out the water
in the heat exchanger and pipes, to prevent frosting.
It is recommended to inject anti-freeze into the pipes.
•Any windows should have curtains or shutters, to
avoid direct sunshine.
•Dry articles should not be put under the machine,
because when the ambient temperature is high or the
drainage is blocked, the machine may drip.
User Cautions
Specification 3 X 1.5 mm2

At Lindab,good thinking is a philosophy that
guides us in everything we do. We have made it
our mission to create a healthy indoor climate – and
to simplify the construction of sustainable build-
ings. We do that by designing innovative products
and solutions that are easy to use, as well as of-
fering efficient availability and logistics. We are
also working on ways to reduce our impact on
our environment and climate. We do that by de-
veloping methods to produce our solutions using
a minimum of energy and natural resources, and
by reducing negative effects on the environment.
We use steel in our products. It’s one of few materi-
als that can be recycled an infinite number of times
without losing any of its properties. That means
less carbon emissions in nature and less energy
wasted.
