2. Important cautions

2.1 Fan coil unit is the terminal device of the chiller system. It is professional very much and with

perfect technology and requirement, so the installation, debugging, operation and management will

be performed by the specified engineer.

2.2 The unit is applicable widely. But please do not use it at the wet place, or on the outside, dirty, or

corrosive environment, and at the explosive place.

2.3 Applicable condition

Power source: 1PH, 220V~, 50Hz.

Max. operation pressure≤1.6MPa.

3. Features

3.1 Four-way cassette type, temperature can be adjusted quickly and equally

3.2 Compact design and space saving

3.3 Powerful circular air flow, quickly adust the temperature

3.4 Auto-restart function

All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will

automatically recover the previous running mode once the power supply is on.

3.5 Security and reliability, long life

Each set of fan coil evaporator will be tested leakage by pressure; water inlet/outlet connection pipe

adopts brass forging structure, reliable and endurable; motor is equipped with the rolling bearing,

no need to add the oil, the life can be up to 60,000 hours; the motor long axis is stainless after the

special treatment.

3.6 High efficiency , sufficient energy

The seamless pipe is cross the slit fin aluminum foil, then be enlarged by the mechanical device to

make the copper pipe and the aluminum foil together, which will get the higher efficiency and

sufficient heating/cooling capacity.

3.7 Large air volume and low noise level

The unit adopts the locked type scroll case, convenient to be taken down; multiple-blade fan. There

will be multiple combinations by the fan and the motor to meet the different requirements.

6. Installation instructions

6.1 Acceptance Inspection

Each fan coil unit is packaged in corrugated cartons to avoid damages during transportation,
handling and site placement.
To make sure no damages occurred due to transportation, please follow below steps to check upon
receiving the equipment:

1.Before acceptance, please check if each unit shows any abnormal facts, if carton edges and
corners are in good conditions and if there’re obvious carton damages;

2.For any obvious carton damages, please immediately unpack to inspect the unit. If the unit is
indeed damaged, please indicate on the receipt and refuse to accept. Please also check the
accessories;

3.Check hidden damages of the unit;

4.If any hidden damage is found, do not move the unit on the site. The receiver has the
obligation to prove such damage does not occured after delivery. Meanwhile, please stop
unloading and take photos for reference;

5.If damages are found, please notify the carrier, and request the carrier and the receiver to
conduct a joint inspection;

6.Do not repair it yourself before inspection and confirmation by the carrier representative has been
made;
After confirmation of damages, please contact relative persons for replacement.

6.2 Installation Precautions

To ensure good installation and operation, do check the following items before installation of the
unit:

● Adequate space shall be provided for installation and maintenance of the unit. Please

refer to Unit Overall Dimensions and Weight. Removable ceiling panels or accesses shall be

provided for daily maintenance;

● Determine locations of pipelines and electric wires before installation;

● Make sure hanging structure adequate for support the unit weight;

● All units shall be leveled to ensure smooth water drain and proper operation;

● The unit connecting air duct shall be within the external static pressure scope;

● Thermal insulation of chilled water valves and pipelines shall be made by the installer.

Note:

● Untreated water may cause unit dirty, corrosion and deterioration. System testing and

maintenance shall be guided by water treatment experts. Haier shall not be held liable for any
losses due to poor water quality.

● Due to limitation of support weight and dimensions, this job shall be collaborated by two

installers to ensure safety.

● During off period in winter, water inside the unit shall be drained away to avoid pipe cracks

because of the ice
