Product Introduction
INTRODUCTION
Johnson Controls YORK® YECAH ceiling mounted compact cabinet fan coil units are
high airflow and high static pressure air-conditioning units using high efficiency 355 mm
diameter EC plug fan(s).
YECAH fan coil units have been designed incorporating variable speed EC motor
technology to meet the needs of today's sustainable building designs and to exceed
the stringent European ErP 2015 energy standard . They are the ideal HVAC solution
for both new construction and revovation projects for hotels, retail centers, office
buildings, and education facilities. The 355 mm diameter EC plug fans operate at lower
RPM , lower noise , and higher efficiency levels when compared to ceiling concealed
units incorporating multiple fans with smaller diameter impellers.
YECAH fan coils are available in 4 models with integral EC fan(s) incorporate fully
variable 0-10v speed control, and are suitable for a wide range of chilled water and hot
water flow rates, including wide delta T applications to maximize pump energy savings.
YECAH fan coil units are available with multiple coil options for each model (the 2 pipe
system has 4 or 6 rows, and the 4 pipe system has 4+1, 6+1, 4+2 or 6+2 rows). The air
flow ranges from nominal 750 L/s to 1500 L/s, while the external static pressure ranges
from 175 Pa to 375 Pa.
large removable access panels to the fan
section.
Cooling and heating coil use copper tubes
with corrugated aluminium fins, mounted
above a full stainless steel drain pan. The
EC plug fan(s) feature EC technology and
with a wide RPM range, can satisfy variable
Each YECAH unit is made of galvanized steel with 15 mm thick non-combustible
airflow and pressure from a 0 - 10 vdc
thermal insulation. It contains built-in cooling & heating coils, single or dual EC variable control signal. A MODBUS high level data
speed plug fan assemblies, a removable inspection panel with sash catches, and
connection is provided as standard.

FEATURES AND BENEFITS
Energy saving
Low noise level
Coil is made of expanded copper tubes and corrugated fins to achieve
high exchange efficiency.
355mm diameter EC plug fans fans provide high efficiency and static
capability over wide operation range
Each fan and motor assembly has been dynamically and statically
balanced
Variable speed, low noise, directly driven EC fan
Significant energy savings
Fan and motor performance rating exceeds the 2015 ErP (European
Energy- related Products Directive)
Whisper quiet comfort condition results in satisfied occupants.
Easy drainage
Full Drain pan allows quick and easy drainage of condensation. Drain
pan is made of high quality stainless steel.
Full drain pan design provides superior condensate management.
Compact size & low
height
Ceiling concealed unit is restricted to 508 mm height to fit within
commercial building ceiling spaces
Suits many ducted HVAC applications
Easy of installation
Threaded Brass connector is provided for easy piping connection. Purge
valves are provided on all coils to assist in commissioning.
Reduces installation and commissioning time and cost.
Easy maintenance
EC fans are direct drive with sealed for life bearings. Inspection panel
allows fast and easy periodic inspection of coil and drain tray. Optional
unit mounted filter track
Reduced maintenance time and cost.

Guide Specifications
GENERAL
Furnish and install ceiling-mounted
compact air handling units not exceding
508mm height as indicated and scheduled
in the plans. Units shall be factory
assembled with coils that are pressure
tested individually to 400 psi (2.8 MPa).
The unit shall incorporate one or two
355mm diameter directly driven EC plug
fans with integral variable speed drive(s).
The units shall be suitable for operation
on 240 volt single phase 50 hz power. BASIC UNIT
The unit panels shall be fabricated out
of 1mm galvanized steel. The unit shall
be lined with 15 mm Class 1 PE thermal
insulation. The fan motor(s) shall be easily
removable for serviceability. A terminal
box with terminal strip shall be provided
for terminating the wiring. An inspection
panel with sash catches shall be provided
for easy inspection of coil and drain
pan.
COILS
Copper tube with corrugated aluminum
hydrophilic fins. Aluminum fins shall be
0.110mm thick and the coil shall have
maximum spacing of 2.3mm between
the fins. The coil shall be pressure tested
under water to 2.8 MPa (For a working
pressure of 1600 kpa) and dehydrated
before assembly. Coil shall be provided
with a manual air vent on the top. The
coil assembly shall be protected on the
side on which piping is to be fitted with a
cover made of GI sheet. A full drain pan
shall be provided to the base of the unit
manufactured of stainless steel to prevent
corrosion. MOTORS
TERMINAL BOX
All units shall be provided with factory
installed terminal box with the fan motor
wired to the box. the terminal box shall
include a DIN rail type terminal strip
that has connections for incoming 240v
power, 0-10v dc speed control, a common
fault contact, and a MODBUS high level
data interface. Where multiple fans are
provided they shall be factory wired to the
common terminal strip.
High efficiency electronically commutated
(EC) motors shall be fitted as standard on
all units. Motor can be regulated by 0-10V FILTER dc signal supplied by a BMS, thermostat
As an option, panel filters shall be provided
or DDC controller. The motor is resiliently to a 25mm channel frame mounted on the
mounted, self aligning and oiled for life.
air inlet of the unit.
A MODBUS high level connection shall be
provided.
FANS
The unit shall utilize one or two 355mm
diameter EC plug fan(s), dynamically
balanced, incorporating backward curved
impellers each with a direct drive EC
motor. The fan motor assembly shall be
designed for low-noise, variable speed
operation from a 0-10v dc control input.
EC fan assemblies shall be installed in
an insulated plenum section with large
removable access panels fitted to both
sides of the air handling unit for ease of
service and replacement.
