PRODUCT DESCRIPTION

DESIGNED FOR MAXIMUM FLEXIBILITY

• The extensive variety of standard options available on vertical floor fan coil units is where you find the versatility to fit any HVAC system designer’s needs. Models KVFF and KVFS allow for additional height and width dimensions to meet architectural demand.
• Options include single wall stainless steel drain pan; MERV 8 and MERV 13 filters; and electric heat with single point power connection. All electric heat units are listed with ETL as an assembly and carry the cETL label.
• All units comply with the latest edition of AHRI Standard 440 for testing and rating fan coil units, are certified, and display the AHRI symbol.
• High-efficiency motors, fan relays, disconnects and fusing mean easier coordination between mechanical and electrical trades.
• Coil options allow for 3 or 4-row chilled water or DX cooling coils, and 1 or 2-row hot water heating coils.
• Silent solid-state relays are available for fan and electric heat control in sound-sensitive environments

OPTIMUM BUILDING PERFORMANCE

• Concealed vertical floor fan coil chassis are built from galvanized steel. This metal surpasses the ASTM 125-hour salt spray test for corrosion and rust. Exposed cabinet models are powder-coated galvannealed steel.
• All units, with or without electric heat, are cETL listed and labelled. All wiring complies with NEC, assuring safety and quality for the owner.
• Floor-mounted cabinet models feature finned tubular heating elements in the reheat position, protecting room occupants from electrical shock.
• Vertical floor fan coil units have a removable fan/drain pan assembly. The entire fan assembly can be easily removed from the unit and serviced on a workbench.
• Filters are easily replaceable from the return air-toe space without the need for tools or removal of the front panel.

CONVENIENT INSTALLATION

• All vertical floor fan coils are shipped completely assembled, reducing field installation time and labour. All units are thoroughly inspected and tested before shipment, eliminating potential problems at startup. Motor wiring is brought to a junction box on the inside of the unit end pocket, reducing electrical hook-up time.
• Factory-furnished valve packages assure proper fit, operation and performance.

CONSTRUCTION FEATURES

• End Pockets: The 8” end pockets allow for accessibility and service of optional factory piping packages and controls. End panels are removable to allow for even greater access.
• Fan Deck: The fan/drain pan assembly is easily removable for service access to motors and blowers at, or away from, the unit.
• Fan Deck Removal: KVF units allow for a single technician to service the fan/motor by keeping the fan deck to less than 44”. Motors are supplied with quick connectors to allow electrical service without the need for tools.
• Drain Pan: The sloped insulated primary drain pan is available in stainless steel construction. The standard drain pan is externally insulated, single-wall galvanized steel. The KVF Series fan/drain pan assembly is easily removable for cleaning.
• Coils: All fan coils are available in 2 or 4-pipe configurations. The heating coil is standard in the reheat position. Heating and cooling coils are available with the same or opposite end connections. Access for cleaning on the entering air side is available when the drain pan is removed. Coils are removable for service.
• Filter: The filter is easily replaceable through the return air toe space without requiring the removal of the front panel.
• Powder Coated Painted Surface: Exposed cabinet Models KVFF and KVFS, as well as supply and return air grilles and the KVFH wall recessing panel, feature a powder coat finish that resists scuffing, scratching, fading, and fingerprints.
• Control Enclosure: The KVF control enclosure provides adequate space for the unit controller and fan coil relay. The fan coil relay is designed to limit diagnostic problems while allowing for multi-voltage fan power input. The board is designed for factory-installed, color-coded, plug-and-play connections designed to ensure accurate wiring.
• Piping Packages: Factory-installed piping packages come equipped with components specific to the project. Actuators ship with colour-coded plug-and-play connections for quick, accurate installations
• Lid Removal: The top panel is removable from the fan coil without the need to disconnect piping or electrical wires.
