READ THIS MANUAL ATTENTIVELY BEFORE STARTING UP THE UNIT. DO NOT THROW IT AWAY. KEEP IT IN The REMQ-P units can be combined with Daikin VRV indoor units for YOUR FILES FOR FUTURE REFERENCE. air conditioning purposes suitable for R410A.
1.1. Combination 1.3. Optional accessories The indoor units can be installed in the following range. To install the above outdoor units, the following optional parts are also required. Always use appropriate indoor units compatible with R410A. To learn which models of indoor units are compatible with Refrigerant branching kit (for R410A only: Always use an R410A, refer to the product catalogs.
11 To prevent dripping water to form a puddle underneath the unit, ELECTION OF LOCATION install a drain pan (available as option kit). This unit, both indoor and outdoor, is suitable for installation in a The equipment described in this manual may cause commercial and light industrial environment.
NSPECTING AND HANDLING THE UNIT NPACKING AND PLACING THE UNIT At delivery, the packing should be checked and any damage should Remove the four screws fixing the unit to the pallet. be reported immediately to the carrier claims agent. Make sure the unit is installed level on a sufficiently strong base to prevent vibration and noise.
6.2. Selection of piping material EFRIGERANT PIPING Foreign materials inside pipes (including oils for fabrication) must be 30 mg/10 m or less. Do not insert fingers, rods or other objects into the air Use the following material specification for refrigerant piping: inlet or outlet.
6.4. Connecting the refrigerant piping Precautions when connecting field piping. Front connection or side connection Add brazing material as shown in the figure. Installation of refrigerant piping is possible as front connection or side connection (when taken out from the bottom) as shown in the figure.

3.1 Precautions when connecting piping between outdoor Prohibited patterns: change to pattern 1 or 2. units (multiple outdoor unit system) To connect the piping between outdoor units, an optional multi connection piping kit BHFQ23P907/1357 is always required. When installing the piping, follow the instructions in the installation manual that comes with the kit.
Branching the refrigerant piping For installation of the refrigerant branching kit, refer to the installation manual delivered with the kit. (See figure 12) Horizontal surface Follow the conditions listed below: - Mount the refnet joint so that it branches either horizontally or vertically.
Vacuum drying: Use a vacuum pump which can evacuate to EAK TEST AND VACUUM DRYING –100.7 kPa (5 Torr, –755 mm Hg) The units were checked for leaks by the manufacturer. Evacuate the system from the liquid pipe, the suction gas pipe, the high pressure/low pressure gas pipe and the equalizer pipe After connecting the field piping, perform the following inspections.

8.3. Power circuit and cable requirements NOTE Select the power supply cable in accordance with A power circuit (see table below) must be provided for connection of relevant local and national regulations. the unit. This circuit must be protected with the required safety Wire size must comply with the applicable local devices, i.e.
This unit has a reverse phase detection circuit. (If it is activated, Use a power wire pipe for the power wiring. only operate the unit after correcting the wiring.) Power supply wires must be attached securely. Outside the unit, make sure the low voltage electric wiring (i.e.
8.8. Field line connection: power wiring Outside unit The power cord must be clamped to the plastic bracket using field Be sure to follow the limits below. If the unit-to-unit supplied clamp material. cables are beyond these limits, it may result in malfunction of transmission.
8.9. Wiring example for wiring inside unit IPE INSULATION figure After finishing the leak test and vacuum drying, the piping must be insulated. Take into account the following points: Power wiring Make sure to insulate the connection piping and refrigerant Wiring between units branch kits entirely.
11. C Be sure to use tools exclusively for R410A to ensure required HARGING REFRIGERANT pressure resistance and to prevent foreign materials from mixing into the system. The outdoor unit is factory charged, but depending on the length of the piping when installed, the outdoor unit may require additional Charging with an unsuitable substance may cause charging.
11.4. How to check how many units are connected 11.5. Additional refrigerant charge It is possible to find out how many indoor units are active and Adding refrigerant using the automatic refrigerant charging connected by operating the push-button switch on the printed circuit function is recommended.
