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.

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 ex- cessive airborne dust and debris. The units must not be operated under any circumstances without an air filter in place.

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 sup- plied with the unit. Failure to do so could result in damage or injury.
