Quite often, the best location for the fan coil unit is suspended from the ceiling of the mechanical room, in the horizontal - Maximizing usable floor space. position (Fig. 03). This will allow for more floor space in the - Location of heating/cooling source to the fan coil. room, and will minimize the duct work needed to connect to the fan coil unit.

As previously stated, the fan coil can be positioned in many different orientations. When placed in the Hi-Boy position, The Hi-Velocity fan coil can be suspended in any position, supply air is fed from the top of the unit (Fig. 01). When placed using most industry standard hanging support systems. in the Counterflow position, supply air is fed downwards from Redi-Rod, All Thread, C-Channel or Unistrut are some of the unit (Fig. 02). the building code acceptable hanging systems. Use these in conjunction with spring or rubber isolators to ensure a sturdy Fig. 01 - Hi-Boy hanging support system. These isolators will absorb most of the vibrations generated by the fan coil system, eliminating any sound transfer. Fig. 02 - Counterflow Securing the Fan Coil to the Hanging System

In most cases, fastening the hanging system near the corners of the outside cabinet of the fan coil will be acceptable. However, in some cases, brackets may be needed to secure the fan coil to the hanging system.

Clearances Clearance is only needed on the access side of the units. However, ensure that there is a small space between the unit and any other surface to prevent vibration transfer. In order to maintain and service the fan coil unit, the minimum clearances required on the access side are (Table 01).

LV-Z Fan Coil - PSB Circuit Board Wiring Cont’d

Emergency Disconnect:

C: Common

C: Common Provides 24VAC to the entire PSB board. In order for “Ro” to receive power it must be connected to terminal “Ri”. This can be done via the three pin jumper header (H1) located above Ro: the terminal strip, a wire jumper or normally closed safety device installed between “Ro” and “Ri”. The jumper pin header (H1) will need to be removed to activate the emergency disconnect option.

Receives 24VAC direct from the transformer. Power must then be sent to the “Ro” terminal Ri: to be distributed throughout the rest of the PSB board.

3 Pin Jumper Terminals:

H1: Emergency Disconnect Pump timer cycles the pump on for 5 minutes every 24 hours to prevent stagnant water. H2 Timer: (on/off) The jumper pin header (H2) will need to be in the ON position for the timer to be active. Switches the control method used by the PSB to control motor speed. “Auto” uses the pressure transducer in order to modulate fan speed to maintain a constant H3 Mode: supply pressure. “Man” allows for direct speed control of the motor by-passing the pressure transducer. The jumper pin header (H3) determines the control method. Cooling/20 second, Heating/30 second fan delay, and 30 second post purge. The jumper H4 Delay: pin header (H4) will need to be in the ON position for the delay to be active.

Diagnostics and Troubleshooting WEG Faults and Possible Causes This section assists the user to identify and correct possible faults that can occur during the CFW-10 operation. When a fault is detected, the inverter is disabled and the fault code is displayed on the readout in EXX form, where XX is the actual fault code. To restart the inverter after a fault has occurred, the inverter must be reset. The reset can be made as follows: R disconnect and reapply the AC power (power-on reset); R press key (manual reset);

The table below defines each fault code, explains how to reset the fault and shows the possible causes for each fault code.

FAULT RESET(1) POSSIBLE CAUSES

E00 Power-on R Short-circuit between two motor phases. Output Manual (key ) R If this fault occurs during power-up, there may be a short. Overcurrent Auto-Reset R Overcurrent Auto-Reset circuit between ground and one or more output (between phases) DI phases. R Inertia of the load too high, or acceleration ramp too short. R IGBT transistor module is short-circuited. E01 R Power supply voltage too high, generating in the DC link a voltage higher DC Link than the allowed value: Overvoltage R Load inertia too high and acceleration ramp is too short.
