2 YAH Product Features Johnson Controls YORK YAH ceiling mounted cabinet fan coil units are terminal points of central airconditioning systems. They are designed for fresh air units or to cool, heat, humidify and dehumidify, filter and clean the air, etc. The conditioned air can be delivered to locations across various distances via specially designed ducts. The units are especially suitable for the airconditioning of commercial buildings and industry applications. YORK YAH series air handling units have different models. The ranges from kw to kw, and air flow from 00 to 000. d external total pressure ranges from 0 to Pa. More external total pressure can be provided for flexible application. Each unit is made from galvanized steel with mm thick polyester fiber insulation. It contains a builtin coil and fan, and externally mounted nylon air filters. Cooling and heating coil use copper tubes with hydrophilic aluminium fins. The fan, motor and belt pulley are all highquality products producing stable and efficient performance. The fan is a forward curved centrifugal model that works on double air inlets. The motor features IP and a type F insulation with selflubricating bearings. The externally mounted filter can be withdrawn from side or bottom.

External total pressure: the sum of velocity pressure and static pressure at the air discharge outlet (exclude the pressure drop across the unit). For fourpiped unit, heating coil is in the front of the coil in the direction of air flow.. If the unit has TiO, evaporative humidifier or split coil (+heating) option, the external total pressure should be deducted by the responding air drop pressure The unit performance is based on m altitude, the variance of altitude will affect the unit performance Altitude correction factors YAHB Altitude(m) heat Sensible heat Note: The above is only for reference.

The direct start schematic diagram (Fig.) is for motor up to.kw. The Y start schematic (Fig.) for motors more than.kw.. The dashed lines is provided by customer and it should be connected according to Fig. or Fig.. Please ensure that all connections are tightened. YAH0B YAH0B YAH0B YAH0B YAH0B YAHB YAHB The evaporative humidification is an isenthalpic process, which is only suitable for comfort airconditioning, and not suitable for the applications where high precision of humidity control is required When the unit is equipped with a evaporative humidifier. The external static pressure of unit should be deducted by air pressure drop across the humidifier.. Fresh air humidification conditions: C DB; 0% RH. Face velocity less than.0m/s.. Mixed air (fresh air ratio at 00%) humidification condition: C DB; % RH. Face velocity less than.0m/s. 0. The above net weight includes the weight of evaporative humidifier, stainless steel frame and water distribution box; the operation weight of the evaporative humidifier is about 0% more than the unit.. The face velocity of direct feeding evaporative humidifier is the same as those of coils All electric connections should comply with local electric installation codes.. The ground terminal of the unit must be connected to the ground terminal in the control panel.. Customer should connect the power and control devices and supply shortcircuit and over heat protection. for placing an order:. The motor power is 0V/N0Hz, 0V/N/0Hz, V/N/Hz, 0V/N/Hz or 0V/N/Hz, wires.. The unit is equipped with plate type prefilters at the return air intake.. When placing an order, the pipe direction (left connection or right) should be noticed (note: facing the return air intake, it is the right if the inlet/outlet water pipes are on the right side of unit and vice versa).. The airflow rate and total pressure should be noticed when placing an order.. If starter is required, it should be noticed when placing an order (an option).
