Product catalog summary
Introduction
The Daikin HiLine™ fan-coil units are designed for flexibility and performance, suitable for multi-floor apartments, office buildings, and hotels. They offer efficient, quiet performance with individual thermostatic control, simple installation, and low maintenance costs. Two designs are available: low CFM (300-800 cfm) for individual room control and high CFM (1000-1200 cfm) for multiple discharge arrangements.
Design Features
Units are available in two configurations: blow-through for sizes 03-08 and draw-through for sizes 10-12. The blow-through design features a removable chassis for easy maintenance, while the draw-through design allows for high CFM performance with low sound levels. Both designs support two-pipe and four-pipe systems with various discharge arrangements.
Installation and Configuration
Installation is streamlined with factory-assembled units and riser slip couplings, requiring minimal labor. Twin units can share risers to reduce costs while maintaining individual control. The FHSK knock-down unit allows for riser installation before unit placement.
Performance and Efficiency
High-capacity, low-flow coils are standard, with separate heating coils for four-pipe systems. Coils are designed for high heat transfer efficiency and are AHRI certified. The units feature efficient, quiet fans and motors with three-speed operation.
Optional Features
Factory-installed risers and valve packages are available, with multiple configurations of motorized valves and optional insulation. Units can be equipped with various thermostats for different control options.
Application Considerations
Units are designed for fast, low-cost installation and offer flexibility for different application requirements. They are suitable for both new installations and retrofits, providing a versatile solution for HVAC needs.
Specifications and Features
The document outlines various specifications and optional features for HVAC systems, including valve packages, flow control, and motor options. It highlights the availability of electric heat units, fresh air dampers, and different grille types. Motors are available in 115/60/1 and 277/60/1 configurations, with features like 3-speed operation and automatic reset overload protection.
Installation Procedures
Two installation methods are described: the basic FHSS unit and the knock-down FHSK unit. The FHSS unit is installed directly above the unit on the floor below, while the FHSK unit allows for riser installation and testing before placement. Both units can be integrated into room designs to minimize space usage.
Application Data
The document emphasizes the importance of accurate system design for efficient fan coil systems. Key considerations include temperature settings, ventilation methods, and heating/cooling requirements. It also discusses the selection of unit sizes based on peak load requirements and ventilation needs.
Piping Systems
Two piping systems are detailed: reverse return and direct return. The reverse return system is self-balancing, while the direct return system requires individual unit balancing. The document also addresses pipe expansion and contraction, recommending methods to accommodate these changes.
Performance Data
Performance tables provide cooling and heating capacity ratings for different unit sizes, based on specific conditions. The document advises using the DaikinTools™ program for precise unit selection.
Additional Considerations
The document covers contractor responsibilities, including the installation of riser couplings and insulation. It also discusses temperature control options and the benefits of twin unit designs for cost efficiency.
Engineering Guide Specifications
Model FHSK (Knock-down Unit)
Specifications
The document outlines the specifications for Daikin's HiLine fan coil units, specifically model FHSK, which are designed for low cfm applications. The units are available in sizes ranging from 03 to 08 (300 to 800 cfm). The units are configurable as either two-pipe or four-pipe systems with a blow-through configuration and a removable chassis for easy access to internal components.
Cabinet and Components
The cabinet is made of heavy-gauge galvanized steel, fully insulated, and includes a sound baffle panel. The return air grille is made of heavy-gauge steel with a semi-gloss finish. Coils are AHRI certified, made of seamless copper tubes with aluminum fins, and include manual air vents. The fan assembly varies by unit size, with fan wheels being dynamically balanced.
Optional Features
Several optional features are available, including discharge grilles, line-of-sight baffles, fresh air dampers, electric heating elements, and twin unit configurations. Controls and valves can be customized for two-pipe or four-pipe systems.
Control Systems
Units can be controlled via a wall-mounted or unit-mounted thermostat, with wiring provided for easy installation. A 10K thermistor is included for temperature control.
Warranty and Services
Daikin equipment is sold with a Limited Product Warranty. For warranty details, customers are advised to consult their local Daikin Representative. Aftermarket services and parts are available through Daikin's website or customer service numbers.
Additional Information
The document emphasizes the importance of proper care and training for Daikin equipment, directing users to Daikin's training resources. The document also notes that all products are manufactured in an ISO Certified Facility.
