When received, a visual inspection of all cartons should be made immediately. Any evidence of rough handling or apparent damage should be noted on the delivery receipt and the material inspected in the presence of the carrier's representative. If damage is found, a claim should be filed against the carrier immediately. In free (non-ducted return air) return installations of YHBC, YHH, YHHS and YHYB units; the furred down area must be completely sealed (except return air grille) to ensure that all return air is pulled from the conditioned space and not from other areas of the building structure. Access must be provided for servicing the unit. If this access is provided by a removable ceiling panel, ample space must be allowed for removal of the blower panel and to provide access to electrical and plumbing controls. Unit must not be operated during building construction due to excessive airborne dust and debris. The units must not be operated under any circumstances without an air filter in place. STORAGE If the equipment is not to be immediately installed, store it in a dry location with the motor protected against moisture, dust, corrosion and physical damage. PREPARE CEILING FOR MOUNTING Depending upon building construction, provisions for mounting the unit must be made by the contractor according to architects; drawings. It is important to ensure that the fan coils are securely mounted and the structure is sufficient to support the weight of the equipment. All anchors for mounting the equipment must be placed and sized to ensure a safe and durable installation. The YHBC, YPHBC, YRHBC, YHH, YHHS, YPHH, YHYB, and YPHYB units are designed for installation in a horizontal position above a dropped ceiling. The YCHBC is a cabinet unit intended for horizontal exposed surface mounting. YORK INTERNATIONAL WIRING All wiring must comply with the local and national code requirements. Units are provided with wiring diagrams and nameplate data to provide information required for necessary field wiring. For power wiring a 4 x 4 electrical box is provided on the cabinet for connection of power supply and is located on the same side as piping. On YHBC units, the box is shipped unattached, it is field attached to the unit in a location convenient to electrical entrance. Any devices such as fan switches or thermostats that have been furnished by the factory for field installation must be wired in strict accordance with the wiring diagram that is supplied with the unit. Failure to do so could result in damage or injury. 3 FORM 115.20-NOM2 (105) INSTALLATION ��� ����� ����� � ��� ���������� ����� �� �������� � � � � � � � � ��� �������� ����� ����������� ��� ����� � � ����� ������ � � ����� ������ � � � ���� � � � ����� ��� ����� ����� ����� ����� �������� ������������ �������� ����� ������ �������� ���� ��� ��� ��� ��� ��� ��� ��� ��� � � � ����� ��� ����� ��� ��� ��� ��� � � � ����� ��� ����� ����� ������ � � � ����� ��� ����� ��� ��� ����� ������ � � � ���� ����� ����� � ��� LD010198 ������ �� ������ ����� ���� ��� � ������ ��� � �� ����� ��� � ��� ����� ��� � �� ����� �� ����������� �� �� �� �� ������ ���������� ������� ������ ����� ������ �� ��� ��� ������ ����� ����� FIG. 2 – HORIZONTAL UNITS - TYPICAL WIRING 4 YORK INTERNATIONAL FORM 115.20-NOM2 (105) INSTALLATION T334 THERMOSTAT Heat-Off Cool, Fan Auto-On, 24V, Manual changeover, 4-Wire Thermostat (R, G, Y, W) Adj.

Metal washers and nuts of the proper size are to be provided by the installer. When necessary, use shims to obtain the proper level. This will ensure that the condensate will drain from the unit. PIPING These units employ a hydronic coil designed for use with either hot or chilled water. All piping must be adequately sized to meet the design water flow requirements as specified for the specific installation. Piping must be installed in accordance with all applicable codes. PIPE SIZES All models except YHYB/YPHYB: • HW/CW coils are 3/8" OD tubing. • Tubing connections are 5/8" OD. Models YHYB/YPHYB: • HW/CW coils are 1/2" OD tubing. • Tubing connections are 7/8" OD. Manual air vents are provided standard on all coils All chilled water piping must be insulated to prevent condensation. Prior to connecting to the fan coil, all external piping must be purged of debris. When connecting piping or valve kits to fan coil units, do not bend or reposition the coil header tubing for alignment purposes. This could cause a tubing fracture resulting in a water leak when water pressure is applied to the system. PRECAUTIONS 1. Flush all field piping prior to connection to remove all debris. 2. Use wet cotton rags to cool valve bodies when soldering. 6 3. Open all valves (mid-way for hand valves, manually open on motorized valves) prior to soldering. 4. When soldering to bronze or brass, heat the piping while in the socket/cup and begin introducing the solder when the flux boils rapidly. Avoid direct flame into the solder joint. 5. Heat can only be applied to the cup of the valve body for a minimal time before damage occurs (even with the use of wet rags. 6. Avoid rapid quenching of solder joints, as this will produce joints of inferior quality. 7. The valve package will not support the weight of the connecting pipes. All pipes, which are connected to the units, must be completely supported prior to connection to the unit. 8. Provisions must be made for expansion and contraction of piping systems. All horizontal and vertical risers, including runouts, must be able to withstand significant movement with temperature changes. Failure to do so will result in damage and failure of piping, fittings and valves throughout the building. 9. Never insulate the heads or motorized portion of control valves. Damage can occur in the form of excessive heat build up and interference to the operation and moving parts will result. 10. All piping made in the field should be installed with consideration of additional space for any electrical routing that may be required. 11. Hydronic systems are not designed to hold pressurized air and should only be tested with water. After the system has been proven leak free, all lines and valve control packages must be insulated as specified on the building plans. Many valve packages will not physically allow all components to fit over an auxiliary drain pan. It is the installers responsibility to ensure adequate condensation prevention. The installer must also ensure that there is no condensate drippage onto electrical components beneath insulated components. YORK INTERNATIONAL FORM 115.20-NOM2 (105) INSTALLATION VALVE CLUSTER 2-Way Motorized Valve Assemblies 1. The motorized valve assembly should be attached to the supply header, which is the connection nearest the air outlet flange on the unit. 2. Prior to soldering the joints, operate all the hand valves to ensure that the handles will fully open and close without interference to other valves, ceiling, wall, plenum or other accessories. 3. All valves will operate at any angle with the exception of the motorized valve, which must be installed with the power head above horizontal. The actuator box requires a 3/4" clearance for removal. 00186VIP FIG. 4 – 2 WAY MOTORIZED VALVE ASSEMBLY 3-Way Motorized Valve Assembly 1. The 3-way valve assemblies will mount to the coil in only one position. On four-pipe right hand systems, a "B" valve assembly is required for the chilled water connection and an "A" valve assembly is required for the hot water connection. On left hand systems, an "A" valve assembly is required for the chilled water connection and the hot water connection. (See figure 4.) 2. Prior to soldering the joints, operate all the hand valves to ensure that the handles will fully open and close without interference to other valves, ceiling, wall, plenum or other accessories. 3. All valves will operate at any angle with the exception of the motorized valve, which must be installed with the power head above horizontal. The actuator box requires a 3/4" clearance for removal. YORK INTERNATIONAL 00187VIP FIG. 5 – 3 WAY MOTORIZED VALVE ASSEMBLY DRAIN PIPING Condensate drain lines must be installed with adequate slope away from the unit to assure positive drainage. YRHBC and YCHBC fan coil units require a minimum trap of 1-1/2 inches be provided in the drain line to assure proper drainage. YHBC, YPHBC, YHH, YPHH, YHYB, and YPHYB fan coil units may be located where the return air space is large enough that a negative pressure is not present, however, a trapped condensate line is recommended to ensure proper drainage of unit in case a negative condition should occur (see Installation Drawings for locations and sizes). The drain should always be connected or piped to an acceptable disposal point sloped away from the unit at least 1/8" per foot LD04801 FIG. 6 – TYPICAL CONDENSATE PIPING TABLE 2 - DRAIN LINE SIZES UNIT PRIMARY SECONDARY YHBC 3/4 MPT 5/8 OD YPHBC 3/4 MPT 3/4 MPT YRHBC 3/4 MPT 3/4 MPT YHH 3/4 MPT 7/8 OD YPHH 3/4 MPT 7/8 OD YHYB 3/4 MPT 3/4 MPT YPHYB 3/4 MPT 3/4 MPT 7 FORM 115.20-NOM2 (105) INSTALLATION Ceiling Concealed Model – MODEL YHBC 6 NOM.

Ensure air filters are clean, installed properly and secured. Use the directional arrows or other information on the filter to determine the proper flow direction. CONTROLS CHECKLIST Check that supply voltage matches nameplate data. Ensure that the unit is properly grounded. Controls installation complete Check all electrical connections for tightness. Review electrical print for correct wiring. Fan INSPECTION - The fan should be inspected and cleaned, in conjunction with maintenance of the motor and bearings. It is important to keep the wheel clean in order to avoid imbalance and vibration. Check tightness of fan bearing locking collar. With power off, check blower wheel set screws for tightness and ensure that the blower wheel(s) rotate freely and quietly. Check tightness of all motor base and mounting bolts. Check motor connections to ensure that they are secure and made in accordance with the wiring diagram Rotate all moving components manually. Adjust as required. YORK INTERNATIONAL 15 MAINTENANCE MOTOR The blower motor should be cleaned annually and if it has oiling ports, it should be oiled with a good grade of SAE 20 oil. Normally a few drops of oil in each bearing is sufficient. COIL The coil must be kept clean by any of the following methods. 1. Cleaning with low-pressure compressed air. 2. Flushing or rinsing with water (a detergent is advisable for greasy surfaces). 3. Prior to the water system start-up and balancing, the chilled/hot water systems should be flushed to clean out dirt and debris, which may have accumulated during construction. All unit service valves are to be closed during this process. Strainers are to be installed in the piping mains to prevent this material from entering the units during normal operation. Because of dust and lint in the room, room-air filters load up much more rapidly than outdoor-air filters. Under normal conditions, the room air filter requires replacement every six to eight weeks. To ensure proper maintenance of the filters, it is best to follow an organized maintenance procedure. The following one is recommended: Divide the total number of units on the job into six equal groups. Each week inspect, clean or replace the filters in each group, in rotation. This insures a uniform servicing interval. The interval may be lengthened or shortened as determined by experience. If inspection shows only the room-air filter to be dirty, this one alone should be replaced. Dirty filters reduce the air and heating capacities of the Unit Ventilator. When the filters are excessively dirty, the unit heating capacity will be so reduced that it is ineffective for heating the room. When a room fails to heat, always check the filters. FILTERS Clean or Replace Air Filters Regularly CLEAN UNIT INTERIOR Once a year clean the fans and coils of the unit thoroughly. Remove the access panel as necessary. The intervals at which filters require replacement depend on local conditions. P.O.
