2 Introduction
1. Introduction
Fan coil unit is a kind of compound device which assemble fan and heat-exchang coil together. Fan coil with
fresh air supply system is a main type of center air-conditioner system, so it is an important component ofAC
devices. Fan coil unit has concealed type and exposed type. A cooling (heating) supply system usually
consists of fan coil terminals and chilled water system (heated water system).
Maxa fan coil is designed and manufactured on the base of advanced technology, and utilize qualified
galvanized iron as material. Due to its supper-thin design, it has such advantages: beautiful outlook, space
saving, easy installation, etc. And the most obvious advantage is that it can decrease the outlet air Temp-
difference as low as possible to make room more comfortable, as well as don’t decrease cooling capacity
output. For the large air flow volume design, it can increase room ventilation frequency, supply more flesh air,
and balance room temperature distribution. Benefiting from adoption of advanced material and technology, it
can effectively decrease the running noise and keep running smoothly. With the advantages above, it can be
widely applied in market, hospital, office building, hotel, airport, etc.

13. Installation
13.1 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 safty items. Observe them and never forget.
Keep the installation 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 the 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 the 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.

Hydronic Highwall
Installation 17
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 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, and then connect the indoor unit wires.
You are not allowed to connect the air conditioner with the power source until wiring and piping the air
conditioner is done.
While following the installation instructions, 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 1meter 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.
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.

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 stereoequipment. (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 information is subject to changes due to technological improvement without further notices.
