Introduction Daikin McQuay Thinline™ Horizontal Fan Coils are intended for use in single zone applications. They are available in sizes from 200 to 1200 cfm. Figure 2 describes the main features of these units and can be referred to for component placement. These units are available in two-pipe configurations with one hydronic coil, with or without electric heat. They are also available in four-pipe configurations with a primary coil and a secondary reheat or preheat coil.
Introduction Safety CAUTION Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations. Have a fire extinguisher available. Follow all warnings and cautions in these instructions and attached to the unit. Consult applicable local building codes and National Electrical Codes (NEC) for special requirements. Recognize safety information. When you see a safety symbol on the unit or in these instructions, be alert to the potential for personal injury.
Introduction IMPORTANT This product was carefully packed and thoroughly inspected before leaving the factory. Responsibility for its safe delivery was assumed by the carrier upon acceptance of the shipment. Claims for loss or damage sustained in transit must therefore be made upon the carrier as follows: VISIBLE LOSS OR DAMAGE Any external evidence of loss or damage must be noted on the freight bill or carrier’s receipt, and signed by the carrier’s agent.
Installation Uncrating and Inspecting the Unit 1. Carefully remove the packaging, remaining alert to any signs of shipping damage. Be careful not to discard components that may be included with the packaging. 2. If the unit is damaged, file a claim with the carrier. Notify the local Daikin McQuay representative immediately. 3. You may want to retain some or all of the packaging to provide jobsite unit location information and temporary protection for the fan coil after installation.
Installation Recommended Maintenance Clearance Cabinet units have removable bottom and side panels for easy access to components for service and maintenance. The fan assembly and main drain pan are easily removable from the bottom for cleaning. See Accessing/Removing the Main Fan Deck and Motor Assembly on page 18 for more information. Figure 5 shows recommended maintenance clearances for hideaway units.
Installation Piping Connection Recommendations General Guidelines • Piping can be steel, copper or PVC, but must comply with local codes. IMPORTANT Venting is required on the return piping for secondary preheat or reheat coils. It is included on factory-built piping packages, but must be added by the installing contractor for field-installed piping.
Installation Drain Piping • Condensate piping can be steel, copper, or PVC. A means of disconnection must be furnished to facilitate fan deck removal. • No point of the drain system may be above the drain pan of any unit. • Pipe insulation is recommended to avoid condensation. • Suggested slope of the drain pipe is at least 1/8" per foot to facilitate adequate condensate drainage but local code requirement should prevail.
Installation If the unit does not have a factory-installed valve & piping package, the changeover switch or sensor can be ordered for field installation. The installer should attach the sensor or auto changeover switch parallel to and in direct contact with the supply water pipe. NOTE: The installer is responsible to ensure the changeover sensor is installed in a location that can sense active water temperature.
Installation Two-pipe systems with electric heat Standard Electrical Connection The electric heating coil is designed to be the total source of heat for the unit. If used for auxiliary intermediate season heating, additional control is required. A second changeover switch is required. For units ordered with intermediate electric heat, the second changeover switch is factory installed.
Installation Electrical Data ECM Blower The wiring diagram for the unit is attached to the exterior of the blower housing. See Figure 10. Be sure the available power is the same voltage and phase as that shown on the unit data plate. See Figure 3, for the location of the data plate. See page 40 through page 42 for typical wiring diagrams. If the unit is equipped with an ECM blower, additional steps may be required during the air balancing process. The ECM blower is controlled by a control board.
Accessories Condensate Overflow Detection Device Electric Heat Over-Temp Reset Button The condensate overflow detection device is a factoryinstalled option on fan coils. This device has a condensate overflow floater with dry contacts and is connected to the LV interface or MicroTech board. See Figure 12. The electric heat options comes with two over-temperature switches. The first resets automatically when the overtemperature condition no longer exists.
Initial Start Up Cleaning & Flushing the Water System • Prior to first operation of any unit, clean and flush the water circulating system of all construction dirt and debris. • If units are equipped with water shutoff valves, either electric or pressure operated, connect the supply and return runouts together at each unit location. This will prevent the introduction of dirt into the unit. See Figure 15.
Initial Start Up Equipment Start Up Check List IMPORTANT Fan coils must be filled with water before operating a circulating pump. Filling the system properly will result in immediate lubrication of the bearings. The pump bearings should not be allowed to operate dry.
Initial Start Up General Maintenance Normal maintenance on all units is generally limited to filter changes and cleaning the condensate drain pans. Units are provided with permanently lubricated motors and require no oiling even though oil caps may be provided. Figure 16: Filter Removal for Units with Bottom Returns Record performance measurements of volts, amps, and water temperature differences (both heating and cooling).
Initial Start Up Electric Resistance Heater Assembly Condensate Drain Pans Electric resistance heaters typically require no periodic maintenance when the unit’s air filters are changed properly. Other conditions and equipment in the system may affect the operation and service life of the heaters. The most important operating conditions for an electric heater is airflow and supply voltage. As a rule, Daikin McQuay recommends operating the electric heater on the High speed, never on Low.
Maintenance Blower Dirt and dust should not be allowed to accumulate on the blower wheels or housing (see typical, Figure 21). Excessive debris can result in an unbalanced blower wheel condition which can damage the wheel and/or motor. The wheel and housing should be cleaned periodically using a brush and vacuum cleaner. Care must be taken to not dislodge the factory balancing weights on the blower blades.
Maintenance Replacement Parts Factory replacement parts should be used wherever possible to maintain the unit’s performance, service life, operating characteristics and testing agency listings. Replacement parts may be purchased through a local Daikin McQuay sales representative. Contact your local Daikin McQuay sales representative or Daikin McQuay Parts before attempting any unit modifications.
Controls and Thermostats Controls Low-Voltage (LV) Interface Board A wide variety of control options are available for Daikin McQuay ThinLine Horizontal Fan Coils, both unit-mounted and remote-mounted. This section provides a brief overview of these options and their operation. For more complete information, contact your Daikin McQuay representative. The low-voltage interface board is used with any remote (wall mounted) Daikin McQuay thermostat or control.
