JOINT KIT “CMY-R160-J” FOR BC CONTROLLER

Joint kit “CMY-R160-J” for the BC controller is used to combine 2 ports of the BC controller at a PURY-P-YGM system so as to enable downstream Indoor capacity above P55 as shown in Fig. 1.

The Joint kit includes the following items:

1. Designing CMY-R160-J to a PURY-P-YGM system
   The maximum downstream Indoor capacity for 1 port of BC controller is P54. When the downstream Indoor capacity is above P54, Joint kit CMY-R160-J is needed to combine 2 ports of BC controller to enlarge the capacity, like Group 2 and 3 in Fig. 1.
   Maximum 3 Indoor units are allowed to connect to 1 port of BC controller or 2 combined ports of BC controller using CMY-R160-J.
   When connecting Indoor units to 1 port of BC controller or 2 combined ports of BC controller using CMY-R160-J, CMY-Y102S-G or CMY-Y104-G is applicable, like Group 1 and 2 in Fig. 1
   Caution: Mixed cooling and heating mode at the same time for Indoor units connecting to 1 port or 2 combined ports is not available.

2. Piping at the installation site
   The connection of CMY-R160-J to BC controller and pipe leading to Indoor units is referable to Fig. 2. Non-oxidized brazing is necessary. All piping must be careful to avoid foreign material getting inside. After piping and air-tight testing, insulation work to the Joint and pipe should be done. Details is available at the Installation Manual.

HIGH STATIC PRESSURE MOTOR PAC-KBU04MT-F

With PAC-KBU04MT-F, the PUHY-P-YGM/YSGM, PURY-P-YGM outdoor unit will gain external 30Pa or 60Pa static pressure, which makes the outdoor unit exhausting design much easier to coordinate with the building situation.

1. Inside the package of PAC-KBU04MT-F, the following items are enclosed together with the installation manual.
2. Installing the high static pressure motor PAC-KBU04MT-F onto the outdoor unit.
3. You may order outdoor unit installed the optional PAC-KBU04MT-F instead of non-static pressure motor, and set the expected external static pressure at shipment, or change the motor by yourself at the field. For the details you need to talk to your provider.
4. In the case you change the motor, and set the expected static pressure at the field. Instruction 2.2a, 2.2b and 2.2c should be followed.
5. Mounting the motor
   A. Remove the screw1, and remove the fan guard, referring to Fig.1.
   B. Remove the screw2, and remove panel 1, referring to Fig.1.
   C. Remove the nut, and remove the propeller fan, referring to Fig.2.
   D. Remove the connector of the motor, referring to Fig.3.
   E. Remove the screw3 of the motor, and exchange the motor, referring to Fig.4.
   F. Connect the motor connectors. Secure the connectors with a clamp below the motor base not directly exposed to rainwater, referring to Fig.5.
   G. Remove the screw4 from both sides of the side panel and replace the side panel with the supplied reinforcing plates. referring to Fig.6. (Other than PUHN type)
   H. Put back the propeller fan, fan guard and panel in the reverse order from A-C. (Bind the nut tight with the torque of 20 ± 2 N·m.)
   I. Attach the supplied label on the unit, referring to Fig.1.

Switching for 30Pa or 60Pa static pressure

1. Remove Panel 2, referring to Fig.1.
2. Remove the control box cover.
3. Set the DIPSW, which is on the front board in the control box, referring to the figure below. (For the DIPSW location, refer to the wiring nameplate on the back of the control box cover).

PUHY-P-YGM, YMM, YUM

PURY-P-YGM

| DIPSW3-9| DIPSW5-1
---|---|---
30Pa| ON| ON
60Pa| ON| OFF
PUHN-P01YGM| DIPSW7-1| DIPSW7-4
---|---|---
30Pa| ON| ON
60Pa| ON| OFF

The fieldwork of 2.2a and 2.2b needs working space at the front and back of the outdoor unit. Enough working space should be considered for the fieldwork of 2.2a and 2.2b. For example, upon corrective installation 20mm or the like interval is helpful.
