Safety instructions and precautions
Device is manufactured in compliance with the following directives:
Machinery Directive, 2006/42/EC;
Low Voltage Directive, EEC 2006/95;
Electromagnetic Compatibility Directive, 2004/108/EC;
Ecodesign Directive, No 1253/2014.
Read this instruction very carefully before installing and using this equipment. Installation, connection and maintenance should be carried out
by a qualifed technician and in accordance with the local rules and legal acts.
The company shall take no responsibility for the injuries suffered by the people or for the damaged property, if the safety requirements are not
followed or the device is modifed without the permission of the manufacturer.
Main safety rules
Danger
• Before performing any electricity or maintenance tasks make sure, that the device is disconnected from the mains, that all
moving parts of the device have stopped.
• Make sure that the fans can not be entered through air ducts or branch openings.
• If you notice liquids on electric parts or connections that bear voltage, stop the operation of the appliance.
• Do not plug the device into the mains, that differs from the one indicated on the label or on the housing.
• Voltage of the mains should comply with the electrotechnical parameters indicated on the label.
• The device should be earthed in accordance with the rules of installation of electric appliances. It is forbidden to turn on and
use unearthed device. Follow the requirements of the device’s labels that indicate Danger.
Warnings
• Connection of electricity and maintenance of the device should be performed only by a qualifed personnel, in accordance with
the manufacturer’s instructions and valid safety requirements.
• In order to reduce the risk during installation and maintenance, suitable protective clothes should be worn.
• Beware of sharp angles while performing installation and maintenance tasks.
• Do not touch heating elements until they haven’t cooled down.
• Some devices are heavy, thus one should be very careful while transporting and installing. Use suitable lifting equipment.
• While connecting electricity to the mains a circuit breaker of suitable size is necessary.
Warning!
• If the device is installed in a cold environment, make sure that all connections and tubes are properly isolated. Intake and
discharge air ducts should be isolated in all cases.
• Openings of the ducts should be covered during transportation and installation.
• Make sure not to damage the heater when connecting the piping of the water heater. For tightening up, use a wrench/spanner.
Before starting the equipment
• make sure, that there are no strange objects inside;
• manually check whether fans are not stuck or blocked;
• if rotary heat exchanger is installed in the device, make sure that it is not stuck or blocked;
• check the grounding;
• make sure that all components and accessories are connected in accordance with the project or provided instructions.
Danger: Fumes
"Salda Antifrost" system uses dis-balancing of the air flow and it may cause negative pressure in premises. Great care should be
taken when using at the same time in premises as another heating appliance what depend on the air in premises. Such
appliances include gas, oil, wood or coal-fred boilers and heaters, freplaces, continuous flow or other water heaters, gas hobs,
cookers or ovens which draw air in from the room and duct exhaust gases out through a chimney or extraction ducting. The
heating appliance can be starved of oxygen, impairing combustion. In exceptional cases harmful gases could be drawn out of the
chimney or extraction ducting back into the room. In this case we strictly recommend to turn off "Salda Antifrost" and use an
external preheater for heat exchanger anti-frost protection (see "Salda Antifrost" function on the Remote controller manual).

The air handling units installed outdoors shall be started only when the following obligatory conditions established by the manufacturer are met:
Units that are stored at the site before installation shall be sealed using additional means in order to prevent the accumulation of moisture inside
the unit.
If the unit is installed and is not started for continuous operation, it must be ensured that no warm/humid air enters the unit through air ducts
and that no moisture condensates inside the unit.
If the ventilation units stand idle for a long time or are started infrequently, the system must be blown down at the maximum capacity 1/24 h to
dehumidify.
Voltage to the automatics of the unit is installed and connected; the system of water products is flled with glycol/water
In case of failure to comply with the requirements set out above, the manufacturer shall have the right not to apply the warranty in respect of the
occurrence of moisture/water in damaged components.

Installation
Reception of goods
Each device is thoroughly checked before transportation. While receiving goods it is recommended to check whether devices were not damaged
during transportation. If a damage to the device is noticed, immediately address the representatives of a transport company. Please inform a
representative of the manufacturer, if any deviation from the order is noticed.
Transportation and storage
The package is only for protection purpose!
While unloading and storing the units, use suitable lifting equipment to avoid damages and injuries. Do not lift units by holding on power
supply cables, connection boxes, air extract or exhaust flanges. Avoid hits and shock overloads. Before installation units must be stored in a
dry room with the relative air humidity not exceeding 70% (at +20 °C) and with the average ambient temperature ranging between +5 °C
and +30 °C. The place of storage must be protected against dirt and water.
The units must be transported to the storage or installation site using forklifts.
The storage is not recommended for a period longer than one year. In case of storage longer than one year, before the installation it is
necessary to verify whether the bearings of fans and motor rotate easily (turn the impeller by hand) and if the electric circuit insulation is
not damaged or the moisture is accumulated.
AmberAir Compact CX P are lifted from the pallet with a forklift or slings.
When lifting with a forklift, protect the condensate
drainage pipes. The product is heavy. Exercise
caution when transporting and installing. Follow
safety requirements established in your country.
