Page 8: Nameplate
YECFC fan coil units have a variable speed driven permanent magnet motor and as such have an extremely wide operating envelope. When fan air supply quantities and external static resistances are extremely low, noise generated by air movement is significantly decreased. -
Page 9: Transportation & Installation
Product Conveyance Installation 2. Transportation & Installation 2.1 Transportation Units are normally shipped ex-works. They are inspected, tested, and packaged prior to dispatch, carefully loaded into containers, shipped to country of destination, unloaded, and delivered to jobsite. Immediately upon receipt at jobsite, inspection should be made for any damage, which must be reported to Johnson Controls within 24 hours of receipt of goods. -
Page 10: Points For Attention During Installation
For ceiling installation, hang the unit on threaded rods using the mounting holes provided. Alternately rubber isolators or spring mounts can be used. YECFC units exhibit low levels of unit vibration and have high levels of balance as each direct drive EC fan / motor assembly is provided as a single manufactured and tested entity from the supplier. -

2.7.6 Air Duct Connection Where YECFC are used in a ducted application, the connecting between the return air duct and the return air opening or return air plenum and that between the air outlet flange and the supply air duct or plenum must be flexible. -
Page 12: Electric Connection
Product Conveyance Installation 3.2 Electric Connection Before wiring, please check voltage, frequency, and phase and confirm whether they are correct. Power connection should be installed according to electric schematic diagram. Earth lead should be connected firmly. Wiring diagram is as Fig.1. The recommended wire size is as below sheet. Several different models of unit sharing a single temperature controller are not prohibited. -

Check whether the fan can rotate freely. Clean the fan blades as required. The normal service life of the fan bearing used in the YECFC unit can be up to 75,000 working hours without service. Bearings are of the sealed type. -
Page 14: Failure Analysis
Product Conveyance Installation 5. Failure Analysis 5.1 Low Air Flow Rate The actual static pressure needed is greater than the design static pressure and. Thus, the air flow rate is lower than the design value. Increase fan speed as required. 5.2 High Air Flow Rate The actual static pressure needed is lower than the design static pressure, making the air flow rate higher than the design value. - Page 15 YORK Guangzhou Air Conditioning & Refrigeration Co., Ltd.
