DESCRIPTION

The YMB Series 2-pipe fan coil comes with a 4-row cooling / heating coil and a 120V multi-speed mo- tor.

The YMBE Series 240V, 2-pipe fan coil comes with a 4 row-cooling coil, 240V multi-speed motor, 240/24 transformer, and up to 25kW of factory installed elec- tric heat. Models with more than 10kW also include a circuit breaker for branch circuit protection. Control voltage is 24V.

The YMBE Series fan coil comes with a 4-row cool- ing coil, 277V multi-speed motor, and up to 10kW of factory installed heat. A unit mounted disconnect is standard.

The YMB-HW Series 4-pipe fan coil includes a 4 row cooling coil, a 2, 3, or 4 row heating coil installed in the reheat position, and a 120V multi-speed motor.

HORIZONTAL APPLICATION

These fan coil units are factory assembled for horizon- tal left side down application without any modification required. To convert to horizontal right side down, remove horizontal drain pan and A-coil assembly, flip horizontal drain pan over to right side and reinstall horizontal drain pan and A-coil into cabinet. Secure forward edge of horizontal drain pan with angle bracket. The unit should be leveled in such a way that there is slope toward the condensate drain nipple to assure positive drainage.

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. All wiring must comply with local and national code requirements.

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.

YMBE SERIES

Fan coil units with 10kW or less electric heat are provided with a terminal block for connection of one electrical service. Units with 15 kW and 20kW are provided with dual circuit breakers for the connection of two electrical services and units with 25kW are pro- vided with three circuit breakers for the connection of three separate electrical services (see Figure 2 & 3).

These units may be provided with a class 2 transformer for 24-volt control circuits. Should any add-on equip- ment also have a class 2 transformer furnished, care must be taken to prevent interconnecting outputs of the two transformers by using a thermostat with iso- lating contacts.
