A. Technical Data A.1. General Description FDBD unit is an ideal air handling terminal unit for suspended ceiling installation and suitable for ducted air distribution. It is constructed of sandwich panels to achieve low noise level during operation. FDBD air handling unit is shipped completely assembled and motor wiring is introduced into the control box to reduce on-site installation time and manpower. Every unit is thoroughly inspected and tested to clear up potential problems during startup. The unit contains side panels that provide easy access to fans, motors and filters.
FRAMEWORK A frameless structure is used. The panel is integrated folding steel structure and tested to ensure that there is no air leakage.
CASING Casing is double skinned and basically consists of two panels with internal insulation. Each panel is 1” thick. The inner and outer panels are made of plane galvanized steel and pre-coated galvanized steel. The insulation consists of a high-pressure PU foam sandwiched in between to reinforce the panel.
FILTER Filter is washable, double-layer acrylic nylon with aluminum frame. G4 (Merv 8) or F8 (Merv 14) filter is optional.
COOLING COIL The Cooling Coil is standard Cu/Al 3/8” OD. The manifolds are made of steel with threaded connections. The Cooling Coil is provided with manual Air-Vent valve. The aluminum fins are pre-coated for protection by hydrophilic blue fin process. Coils are tested at 30 bar (435 PSI) and recommended operating at no more than 16 bar (232 PSI).
DRAIN PAN Drain pan is made of single wall painting steel with 3/16" insulation on outer wall. The drain pan extends the full length and width of the coil and is sloped for positive drainage and includes 3/4” male pipe threaded galvanized drain connector.
FAN SECTION Fans are mainly constructed of housing, impeller, mounting feet, and AC motor. The housing is made of hot-dip galvanized steel. The side panel includes inlet cones whose inlet conditions are designed for optimum aerodynamics. The scroll is fixed on the side panel by spot welding. The wheel is made of hot-dip galvanized steel. The forward curved blades feature an advanced aerodynamic design for maximum efficiency and minimum noise level. The impeller is fixed on the center plate and on the end ring with riveting compression. The impeller is designed for maximum strength and can withstand continuous operation with maximum power. All impellers and motor are fully balanced according to ANSI/AMCA-204 standard. The mounting feet are made of galvanized steel sheet with unique technical to ensure adequate strength.
TERMINAL STRIP (T TYPE) A 230Vac relay is used to drive 1-speed AC motor. 40VA (24Vac) transformer is optional which supplies power to thermostat and modulating valve.
ACCESSORIES Optional accessories can be selected: G4 (Merv 8) filter module, Mixing and recirculating chamber, 0~10V Modulating 2-way valve kit, On/Off 2-way valve kit, On/Off 3-way valve kit, Electrical heating module, AC/EC thermostat, AQI control PCB-S5, Complete function PCB-S6, Wired wall pad, Differential pressure transducer.

B. Installation B.1. Safety Precautions When installing, performing maintenance or servicing Daitsu fan coil units observe the precautions stated in this manual
as well as those stated on the labels attached to the unit. Ensure all local and national safety codes, laws, regulations, as well as general electrical and mechanical safety guidelines
are followed for installation, maintenance and service. The appliance is for indoor use only. Ensure the correct power supply is provided. If the power supply cord is damaged, it must be replaced by qualified personnel. Installing and servicing fan coil unit should be performed by qualified service personnel only. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or persons lacking in experience and knowledge of the appliance, unless they have been given supervision or instruction concerning it.
User of this appliance is responsible for his/her own safety. Warranty shall be voided if installation instructions and safety precaution stated in this manual are not observed. The unit should only be switched off by using the ON-OFF button on the control interface.
B.2. Location Before installing and running the unit, please check the following: 1. There must be enough space for the unit installation and maintenance. Please refer to the below figures for the unit's
outlines and dimensions and for the minimum distance between the unit and the obstacle/ any obstructions/ its surroundings.
2. Please ensure there is enough space for piping connections and electrical wiring. 3. Check whether the hanging rods can support the weight of the unit (see specification table for weight of the unit). 4. The unit must be installed horizontally to ensure proper operation and condensate draining. 5. The external static pressure of the ducting must be within the unit’s static pressure range. 6. Confirm that the unit has been switched OFF before installing or servicing the unit.

CAUTIONS
Before any service or maintenance operations turn off the mains electrical supply.
DO NOT turn OFF the main power supply when the unit is operating. Turn off the unit BEFORE turning off the main power

CAUTION
Make sure the top of the unit is level after installation. The drain pan is designed with a slight gradient to facilitate drainage.
CAUTIONS
Dimension M and N are determined by air duct design. Air duct should be fire-proof. Please refer to concerned country national and local regulation. Circulatory air pressure drop should be approximately equal to the External Static Pressure.
Page 12 of 20
B.4. 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. 3. It is also necessary to insulate the air duct.
B.5. Air Duct Connection 1. Circulatory air pressure drop should be within External Static Pressure. 2. Galvanized steel air ducts are suitable. 3. Make sure there is no leak of air. 4. Air duct should be fire-proof, refer to concerned national and local regulations.
B.6. Pipe Connection 1. Using suitable fittings 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. Drain pipe can be PVC or steel. 5. Tightening torque should not be too high when connecting water pipes, in order to avoid brass deformation or water-
leakage by torsion split. 6. The suggested slope of the drain pipe is at least 1:50.
B.7. Electrical Connection Standard Terminal Block
CAUTION
When connecting pipe to fan coil unit, do not bend or reposition the coil header for alignment purposes. This could cause a tubing fracture resulting in a water leak when water pressure is applied to the system.

C. Maintenance
C.1. General Maintenance 1. Installation and maintenance should be performed by qualified personnel who are familiar with local
codes and regulations and experienced with this type of appliance. 2. Confirm that the unit has been switched OFF before installing or servicing the unit. 3. A good general maintenance plan will prevent damage to and unexpected shutting down of the equipment. 4. Dirty filters reduce air flow as well as unit performance. Therefore, changing or cleaning the filters is very
important. Check the cleanliness of the filter and replace or clean as required monthly. 5. Coils should be cleaned with compressed air or water to remove dust, dirt or lint. They can be brushed
with a soft brush or vacuumed with a vacuum cleaner. 6. If the water coil is not being used during the winter season it should be drained, or an anti-freezing
solution should be added to the water circuit to avoid freezing.
C.2. Regular Maintenance 1. Inspect and clean the condensate drain pan to avoid any clogging of the drain by dirt, dust, etc. Inspect
drainage piping to ensure the proper condensate flow. 2. Check and clean the coil. Clean the coils with a low-pressure water jet or low-pressure air. 3. Clean and tighten all the wiring connections. 4. Drain out the water system and check for buildup of residue deposits.
C.3. Filter Cleaning 1. Remove the filter from the rear or bottom. 2. Clean the filter with a brush, or with water. 3. Reinstall the filter by sliding it back into the groove.
C.4. Fan Replacement 1. Loosen the screws from front panel. 2. Remove the fixing nuts of fan blower. 3. Replace the fan. 4. Reinstall the front panel with screws.
