FUJITSU FOC1524VJAZCA1 iM Air Conditioners

Product Information

The iM Air Conditioners FOC15 is a series of air conditioners manufactured by Fujitsu General America, Inc. It offers cooling efficiencies up to 15.2 SEER2/9.8 EER2 and comes in nominal sizes ranging from 2 to 5 tons (7.0 to 17.6 kW).
The cooling capacities of the FOC15 range from 22.8 to 56.0 kBTU (6.68 to 16.4 kW).
The FOC15 air conditioners provide precise temperature control, advanced humidity control, and greater efficiency. They feature a 3-speed operation when installed with a 24V two-stage thermostat.

Product Usage Instructions

To use the iM Air Conditioners FOC15, follow these instructions:

Ensure that the air conditioner is properly installed according to the manufacturer’s guidelines.
Connect the air conditioner to a suitable power source with the specified line voltage (208/230V-1-60Hz).
Set the desired temperature and mode using the controls provided on the air conditioner or the connected thermostat.
If available, use a 24V two-stage thermostat for optimal performance and access to the 3-speed operation feature.
Monitor the air conditioner’s performance and adjust the settings as needed to maintain the desired temperature and humidity levels.
If additional accessories are desired, refer to the accessories section of the user manual for compatibility and installation instructions.
Regularly clean and maintain the air conditioner as recommended in the user manual to ensure efficient operation and prolong its lifespan.

Application Guidelines

Intended for outdoor installation with free air inlet and outlet. The outdoor fan external static pressure available is less than 0.01 -in. WC.
The minimum outdoor operation air temperature for a cooling mode without a low-ambient operation accessory is 55°F (12.8°C).
Maximum outdoor operating air temperature is 125°F (51.7°C).
For reliable operation, the unit should be level in all horizontal planes.
Use only copper wire for electric connections at the unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
Do not apply capillary tube indoor coils to these units.
Factory-supplied filter drier must be installed.

NOTES:

Do not exceed 150 ft. linear line length.
*Do not exceed 50 ft. vertical separation if the outdoor unit is above the indoor unit.
**A 3/4″ suction line should only be used for 2-ton systems if the outdoor unit is below or at the same level as the indoor unit to ensure proper oil return.
Always use the smallest liquid line allowable to minimize refrigerant charge.
Applications shaded in light gray indicate capacity multipliers between 0.90 and 0.96 which are not recommended but are allowed.
Applications shaded in dark gray are not recommended due to excessive liquid or suction pressure drop.
