Features
Compact
■ Light-weighted, good-looking appearance, and compact and solid structure.
■ 235 mm height, allowing installation on the ceiling with a limited space.
Low-noise
■ Low-noise motor for driving the low speed fan with a wide impeller; strictly tested before delivery.
■ Precise distance between the impeller inlet/outlet and the heat exchanger for more reasonable air ow
distribution.
■ Highly efcient sound-absorbing and heat-preserving materials inside to minimize noises produced by the unit.
Reliable
■ Single-phase capacitor motor with the protection grade IP20 and insulation grade B to ensure operation safety.
■ Permanently lubricated and sealed ball bearing with high precision, which is provided by internationally famous
brands and receives processing including hardening and tempering as well as chroming.
■ Motor power outlet wires protected by metal hoses to ensure its durability.
■ Working pressure up to 1.6 MPa and test pressure up to 2.0 MPa for the heat exchanger to endure high
pressures and prevent leakage.
High Efciency
■ Heat exchanger with the high-quality mechanically expanded copper pipe and hydrophilic aluminum ns to
ensure high efciency.
■ Intensied air supply using a large air ow fan with a wide impeller to maximize the heat transfer performance.
■ Precise matching of the fan and motor to guarantee the maximum cooling capacity but a low power input.
Flexible
■ Multiple external static pressures designed based on the unit’s cooling capacity, meeting the air supply
requirements at different distances.
■ Optional bottom return air plenum or back return air plenum with support for onsite changes, featuring time
saving.
■ Variable accessories for more options.
Anti-leakage
■ Delicate condensate-proof drain pan made of the cold-rolled steel through one-time impact molding, with
coating on both sides and high-quality heat-preserving materials on the exterior.
■ Unique independent mounting bracket without soldering seams or joints, requiring no bolts for xing to prevent
damages to the drain pan heat-preserving layer or cold bridges.
■ Tilt structure for rapid condensate water drainage.

Installation
Receiving
All units leaving the DAIKIN plant have been inspected to ensure the shipment of high quality products and
reasonable means are utilized to properly pack the fan coil units to protect them in transit.
Carefully inspect all shipments immediately upon delivery. When damage is visible, note this fact on the
carrier’s freight bill and request that the carrier sends a representative to inspect the damage. This may be
done by telephone or in person, but should always be conrmed in writing.
The shipment should be unpacked in the presence of the agent so that the damage or loss can be determined.
The carrier’s agent will make an inspection report and a copy will be given to the consignee for forwarding
to the carrier with a formal claim.
Location
Before installation, please check the following:
There must be enough space for unit installation and maintenance. Please refer to the unit’s drawings and
dimensions and g.1 for the minimum distance between the unit and obstacle.
Please ensure enough space for piping connection and electrical wiring.
Please make sure that the hanging rods can support weight of the unit.
Installation
The unit is designed for concealed ceiling installation.
There are holes on the top of the unit for hanging. Please refer to Fig.1.Fig.2 and Fig.3.
Make sure that the top of the unit is level.
Insulation
1) Use proper insulation material only
2) Chilled water pipes and all parts on the pipes should be insulated
3) It is also necessary to insulated air ducted
4) Adhesive for insulation should work under range 0˚F(-18˚C) to 200˚F(93.3˚C).

Air Duct Connection
Circulatory air pressure drop should be within External Static Pressure
Galvanized steel air ducts are suitable
Make sure there is no leak of air.
Air duct should be reproof, refer to concerned country national and local regulations.
Pipe Connection
Using suitable ttings as water pipe connections. Refer to the specication
The water inlet is on the bottom while outlet on top.
The connection must be concealed with rubberized fabric to avoid leakage.
Drainpipe can be PVC or steel.
The suggested slope of the drainpipe is at least 1:50.
Wiring
1) Wiring connection must be done according to the wiring diagram on the unit.
2) The unit must be GROUNDED well.
3) An appropriate strain relief device must be used to attach the power wires to the terminal box.
4) A 7/8” knockout hole is designed on the terminal box for eld installation of the strain relief device.
5) Field wiring must be complied with the national security regulations.

Valve Kit
The valve kit is applied for 2-pipe system.
The kit consists of (refer structure gure 0):
• 2/3 way valve body is made of brass, maximum working pressure 1.6MPa.
• Electric actuator has the following specications:
-Power supply: 220V±10%/50/60Hz (±2Hz)
-Activation: ON/OFF
• Hydraulic kit for the installation of the valve on the heat exchanger, complete with 2 ball valves for
adjusting the water ow and for closing the water circuit when perform maintenance to the unit.
• Y-strainer protects unit from impurity, increases the service life and insolating valves.
All parts of 2-way valve kit are indicated in the gure 1. ( For right pipe connection unit.)
All parts of 3-way valve kit are indicated in the gure 2. ( For right pipe connection unit.)

Installation
1. Install the 2-way valve kit as indicated in the pictures of gure 3. (For right pipe connection unit.) As
shown as detail A, rstly take apart connector, then install ①to unit with necessary sealing material . Fix
②between ①and ③. At last tighten ③, make sure all of connectors are sealed.
2. Install the 3-way valve kit as indicated in the pictures of gure 4. (For right pipe connection unit.) Detail is
as same as 2-way valve unit.
The valve kit has been pre-assembled for easy installation.
• Where needed the connections are pre-coated with sealing material.
• The connections are not tightened for easy adjustment.
• After determining the nal position of the valve kit, tighten all connections to obtain water tightness.

Insulation
1. The insulation design and materials should be complying with local and national codes and regulations.
2. Chilled water pipes and all parts on the pipes should be insulated.
The ow resistance of the connecting valve/hydraulic kit assembly is obtained from the following formula:
△PW= (QW/100Kv)2
PW is the ow resistance (Pa)
QW is the water ow rate (m3/h)
Kv is the ow rate identied in the table
Valve Model DN Conncetion
Type Valve Type KV Shut-off Pressure Difference (MPa)
MC-FCV3335G 20 Rc3/4" 3-way Valve 3.4 0.18
MC-FCV2334G 20 Rc3/4" 2-way Valve 3.0 0.18
Pipe Connection
1. Using suitable ttings as water pipe connections with reference to the outline and dimensions.
2. The water inlet is on the bottom while outlet on top.
3. The connection must be concealed with rubberized fabric to avoid leakage.
4. Tightening torque should not be too high when connecting water pipes, in order to avoid brass deformation
or water-leakage by torsion split.
Wiring
1. Refer to the wiring diagram of the appropriate controller.
2. For connection with the DAIKIN controller, position the water temperature probe into the appropriate
position. Refer to the dedicated controller installation and operation manual.
