All field-installed kits come with thorough, easy to follow instructions.
All air handlers are top-handling packaged with bar coding and full description on the label.
Electrical connections can be made on top or right side.
All coils are individually pressure tested at 500 PSI, then pressurized and sealed.
Magnetic filter rack doors:
Easy filter replacement.
Tight seal for less air leakage.
Fiberglass air filter comes with every air handler.
Filter rack accepts standard size filters sold in hardware stores.
1.2 Rules for Use with VRV-Systems
The Vertical Air Handler Unit is manufactured as two separate components: FXOQ__MVJU Air Handler and
BEQ__MVJLR1 Junction Box.
When applying this new air handler, the KRCS01-1 Remote Temperature Sensor Kit is a necessary addition for all
FXOQ+BEQ Indoor Units.
The FXOQ+BEQ unit can be used on all VRV, VRV-S, and VRV-WII Systems.
The Application Range (Connection Index) for the FXOQ+BEQ unit is limited to 50-130%.
The FXOQ+BEQ unit cannot be installed on the same system as that containing indoor units from another VRV indoor unit
family (i.e. RXYMQ with FXOQ and FXSQ is NOT PERMITTED).
The FXOQ+BEQ unit is permitted for 208V/1/60 Applications only.
All projects using the FXOQ+BEQ solution must be reviewed and verified (in writing) by the Daikin AC Internal Sales
Department for the following items: Total capacity index, Total Air Handler Coil Index, and System Configuration.
The FXOQ Air Handler is approved for upflow installations ONLY.
The FXOQ has a Backup Electric Heater Option (5kW to 25kW) that is field installed. When using the Backup Electric Heater
Option, the system requires the Lockout Function accessory PCB for VRV Heat Pump and Heat Recovery Condensing Units.
Standard Wired Controllers (BRC1D71 or BRC2A71) can be used with this product.
A BRC4C Wireless Controller can be used for wireless applications.
Unit Fan speed is selectable as H and L, but airflow stays the same.
1.3 BEQ Junction Box Application Rules
The BEQ is power supplied from the FXOQ Air Handler Unit.
The BEQ supports 208V1/60 Power Supply ONLY at this time (no 230 or 240/1/60 is permitted).
Maximum Piping Distance between BEQ and FXOQ permitted is 10 feet.
Maximum Height Separation between BEQ and FXOQ permitted is 7 feet.
Maximum Piping Distance between FXOQ and 1st REFNET Joint permitted is 7 feet.
Pipe sizing downstream of the BEQ junction box (BEQ to FXOQ) follows the BEQ Spec Table.
Pipe/REFNET sizing upstream of the BEQ junction box as per normal VRV rules.
