NORDIS MD13I-013CW Wall Mounted Fan Coil Type Instruction Manual

INSTALLATION MANUAL

Wall-mounted Fan Coil Type

Thank you very much for purchasing our air conditioner,
Before using your air conditioner, please read this manual carefully and keep it for future reference.

1. PRECAUTIONS

• Be sure to be in conformity with the local, national and international laws and regulations.

• Read “PRECAUTIONS” carefully before installation.

• The following precautions include important safety items. Observe them and never forget.

• Keep this manual in a handy place for future reference.

• Before out from factory, FAN COIL UNIT (AIR UNITS) has passed Fan Coil Overpressure Resistant Test, Statically and Dynamically Balanced Adjustment, Noise Test, Air (cool) Volume Test, Electric Property Test, Outline Quality Detection.

The safety precautions listed here are divided into two categories. In either case, important safety information is listed which must be read carefully.

WARNING

Failure to observe a warning may result in death.

CAUTION

Failure to observe a caution may result in injury or damage to the equipment.

After completing the installation, make sure that the unit operates properly during the start-up operation. Please instruct the customer on how to operate the unit and keep it maintained.

WARNING

Be sure only trained and qualified service personnel to install, repair or service the equipment.
Improper installation, repair, and maintenance may result in electric shocks, short-circuit, leaks, fire or other damage to the equipment.

Install according to this installation instructions strictly.
If installation is defective, it will cause water leakage, electrical shock and fire.

When installing the unit in a small room, take measures against to keep refrigerant concentration from exceeding allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can lead to oxygen deficiency.

Use the attached accessories parts and specified parts for installation.
otherwise, it will cause the set to fall, water leakage, electrical shock and fire.

The appliance must be installed 2.3m above floor.

The appliance shall not be installed in the laundry.

Before obtaining access to terminals, all supply circuits must be disconnected.

The appliance must be positioned so that the plug is accessible.

The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the fluid flow.

For electrical work, follow the local national wiring standard, regulation and this installation instructions. An independent circuit and single outlet must be used.
If electrical circuit capacity is not enough or defect in electrical work, it will cause electrical shock fire.

Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on the terminal.
If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

Wiring routing must be properly arranged so that control board cover is fixed properly.
If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.

If the supply cord is damaged, it must be replaced by the manufacture or its service agent or a similarly qualified person in order to avoid a hazard.

An all-pole disconnection switch having a contact separation of at least 3mm in all poles should be connected in fixed wiring.

When carrying out piping connection, take care not to let air substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle.

Do not modify the length of the power supply cord or use of extension cord, and do not share the single outlet with other electrical appliances.
Otherwise, it will cause fire or electrical shock.

If the water leaks during installation, ventilate the area immediately.

After completing the installation work, check that the water does not leak.

The cool water in the unit is not lower than 3, hot water is not higher than 70. Water in the unit must clean, air quality must meet to the standard of PH=6.5~7.5.

CAUTION

Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning rod or a telephone ground wire. Incomplete grounding may result in electric shocks.

Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks.

Connect the outdoor unit wires , then connect the indoor unit wires.
You are not allow to connect the air conditioner with the power source until wiring and piping the air conditioner is done.

While following the instructions in this installation manual, install drain piping in order to ensure proper drainage and insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and property damage.

Install the indoor and outdoor units, power supply wiring and connecting wires at least 1 meter away from televisions or radios in order to prevent image interference or noise.
Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the noise.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Condensate water may be generated when machine operates in an open environment.

Don’t install the air conditioner in the following locations:

• There is petrolatum existing.

• There is salty air surrounding (near the coast).

• There is caustic gas (the sulfide, for example) existing in the air (near a hot spring).

• The Volt vibrates violently (in the factories).

• In buses or cabinets.

• In kitchen where it is full of oil gas.

• There is strong electromagnetic wave existing.

• There are inflammable materials or gas.

• There is acid or alkaline liquid evaporating.

• Other special conditions.

2. INSTALLATION INFORMATION

• To install properly, please read this “installation manual” at first.

• The air conditioner must be installed by qualified persons.

• When installing the indoor unit or its tubing, please follow this manual as strictly as possible.

• If the air conditioner is installed on a metal part of the building, it must be electrically insulated according to the relevant standards to electrical appliances.

• When all the installation work is finished, please turn on the power only after a thorough check.

• Regret for no further announcement if there is any change of this manual caused by product improvement.

INSTALLATION ORDER

• Select the location;
• Install the indoor unit;
• Install the outdoor unit;
• Connect the drain pipe;
• Wiring;
• Test operation.

Cautions on remote controller installation:

• Never throw or beat the controller.
• Before installation, operate the remote controller to determine its location in a reception range.
• Keep the remote controller at least 1m apart from the nearest TV set or stereo equipment. (it is necessary to prevent image disturbances or noise interferences.)
• Do not install the remote controller in a place exposed to direct sunlight or close to a heating source, such as a stove.
• Note that the positive and negative poles are right positions when loading batteries.
• This manual is subject to changes due to technological improvement without further notices.
