When the internal downstream capacity is above P80, the common kit CMY-R160-J1 is needed to combine 2 ports of the BC controller to expand the capacity, such as group 2 and 3 in Fig. When connecting indoor units with 1 BC controller port or 2 combined BC controller ports using CMY-R160-J1 or CMY-Y102SS-G2 are applicable, such as group 1 and 2 in Fig. The connection of the CMY-R160-J1 to the BC controller and the pipe leading to the indoor units can be referred to Fig.
The Joint kit include following items
Attention: Mixed mode of cooling and heating at the same time for indoor units connected to 1 port or 2 combined ports is not available. After the wiring and air tightness test, the joint and pipe insulation must be performed. The BC controller common kit "CMY-R160-J1" is used to combine 2 BC controller ports in a PURY/PQRY system to enable indoor performance down above P80 as shown in the picture.

Exercise caution when transporting products
Install the unit in such a way that the corner of the angle bracket at the bottom of the unit shown in the figure is securely supported. When using a rubber pad, it must be installed so that the pad covers the entire width of the unit's legs. Install the unit in such a way that the corner of the angle bracket at the bottom of the unit shown in the figure below is securely supported.
WARNING
Install the unit on a durable base made of materials such as concrete or angle steel. When routing the pipes and/or cables at the bottom of the unit, make sure that the through hole at the base of the unit is not blocked with the installation base. To prevent small animals, water and snow from entering the unit and damaging its parts, close the.

Installation base parallel to the unit's front panel Installation base perpendicular to the unit's front panel. The pipe from several outdoor units must be installed so that under certain conditions oil does not accumulate in the pipe. In the figure on the right, because the pipe slopes upwards, the oil accumulates in the pipe when unit 1 is operating and unit 2 is stopped.

13-5. Precautions for installing a panel heater
- Install the salt-resistant unit out of direct exposure to sea breeze, and minimize the exposure to salt water mist
- Avoid installing a sun shade over the outdoor unit, so that rain will wash away salt deposits off the unit
- Install the unit horizontally to ensure proper water drainage from the base of the unit. Accumulation of water in the base of the outdoor unit will significantly accelerate corrosion
- Periodically wash salt deposits off the unit, especially when the unit is installed in a coastal area
- Repair all noticeable scratches after installation and during maintenance
- Periodically check the unit, and apply anti-rust agent and replace corroded parts as necessary
The AUTO mode of the local remote controller is available only when the fresh air intake type indoor unit is connected to the outdoor unit R2 or WR2 series.
