Installation Instructions

Drain joint installation Heat pump units require a drain joint. Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of drain joints depending on the type of outdoor unit.
If the drain joint comes with a rubber seal (see Figure 10, pos. A ), do the following:
1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the base pan of the unit.
3. Rotate the drain joint 90° until it clicks in place facing the front of the unit.
4. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.
If the drain joint doesn’t come with a rubber seal (see Figure 10, pos. B), do the following:
1. Insert the drain joint into the hole in the base pan of the unit. The drain joint will click in place.
2. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit during heating mode.

Drilling a hole in the wall You must drill a hole in the wall for the refrigerant piping and signal cable that will connect the indoor and outdoor units. 1. Determine the location of the wall hole based on the location of the outdoor
unit. 2. Use a 6.5 cm (2.5 in) drill bit and drill a hole in the wall.
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and helps seal it when you finish the installation process.

NOTICE
In cold climates, make sure that the drain hose is as vertical as possible to ensure swift water drainage. If water drains too slowly, it can freeze in the hose and flood the unit.

CAUTION: SLIPPING HAZARD
Make sure the water drains to a safe location where it will not cause water damage or a slipping hazard.

Installation Instructions
7 Refrigerant Piping Connection
WARNING: All field piping must be completed by a licensed technician
and must comply with the local and national regulations.
When the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage. If the refrigerant leaks and its concentration exceeds its proper limit, hazards due to lack of oxygen may result.
When installing the refrigeration system, ensure that air, dust, moisture or foreign substances do not enter the refrigerant circuit. Contamination in the system may cause poor operating capacity, high pressure in the refrigeration cycle, explosion or injury.
Ventilate the area immediately if there is refrigerant leakage during the installation. Leaked refrigerant gas is both toxic and flammable. Ensure there is no refrigerant leakage after completing the installation work.

NOTICE:
Be extra careful not to damage, kink, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit.

Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed. 1. Hold the pipe at a downward angle to prevent burrs from falling into the
pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

Reamer

7.1 Connection Instructions ­ Refrigerant Piping
NOTICE: The branching pipe must be installed horizontally. An angle
of more than 10° may cause malfunction.
DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
Insulate both the gas and liquid piping to prevent water leakage.
Step 1: Cut pipes When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient operation and minimize the need for future maintenance.
1. Measure the distance between the indoor and outdoor units. 2. Using a pipe cutter, cut the pipe a little longer than the measured distance. 3. Make sure that the pipe is cut at a perfect 90° angle. Refer to Fig.12 for cut
examples.

Point down
Figure 13
Step 3: Flare pipe ends Proper flaring is essential to achieve an airtight seal. 1. After removing burrs from cut pipe, seal the ends with a piece of tape to
prevent foreign materials from entering the pipe. 2. Sheath the pipe with insulating material. 3. Place flare nuts on both ends of pipe. Make sure they are facing in the
proper direction, because you can’t put them on or change their direction after flaring. See Figure 14.

9 Evacuation and Charging Process
9.1 Preparations and Precautions
Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system. Evacuation should be performed upon initial installation.
Before performing evacuation Check to make sure that both high-pressure and low-pressure pipes
between the indoor and outdoor units are connected properly in accordance with the Refrigerant Piping Connection section of this manual. Check to make sure all wiring is connected properly. Perform nitrogen leak check on all refrigerant joints.
9.2 Evacuation Instructions
Before using the manifold gauge and vacuum pump, read their operation manuals to familiarize yourself with how to use them properly.

3. Open the low pressure side and high pressure side service valves (A1, B1, C1, A2, B2, C2, etc.) if the lineset was connected.
4. Open the Low Pressure side valve on the manifold gauge. Keep the High Pressure side valve closed.
5. Turn on the vacuum pump to evacuate the system.
6. Run the vacuum until the Compound Meter reads -76cmHg / -29.92″Hg (-101 kPa). It is recommended to use a micron gauge; run the vacuum until the micron gauge reads 350 to 500 microns or less.
7. After the vacuum process has been achieved, close the Low Pressure side valve on the manifold gauge, and turn off the vacuum pump.
8. Wait for approximately 10 to 15 minutes, then check that there has been no change in system vacuum. It is recommended to use a micron gauge; check to make sure the system is still below 500 microns.
9. If there is a change in system vacuum, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system vacuum, remove the charge hose from the service port.

Bosch Climate 5000 Series Multi Zone Ductless Air Conditioner / Heat Pump (06.2022)

9.4 Calculation Steps Step1: Calculate the “Estimated” refrigerant pre-charge amount.
Please note this value is only used to calculate the additional refrigerant charge amount.
Estimated Pre-charge Amount = Standard Refrigerant Pipe Length 0.16oz/ft. (15g/m)
Step2: Calculate the required charge amount for each zone (Refer to Table 8 for Indoor unit liquid line diameter) If the Zone 1 Indoor unit has 3/8inch liquid line diameter:
Zone 1 Charge Amount = Zone 1 Refrigerant Pipe Length 0.32oz/ft (30g/m) If the Zone 2 Indoor unit has 1/4 inch liquid line diameter:
Zone 2 Charge Amount = Zone 2 Refrigerant Pipe Length 0.16oz/ft. (15g/m) Total zone charge amount = Zone 1 charge amount + Zone 2 charge amount + Zone 3 charge amount + … up to 5 zones.
Step3: Calculate the additional refrigerant needed Additional Refrigerant Amount = Total Zone Charge Amount – Estimated
Pre-charge Amount
For example: One 36K ODU (BMS500-AAM036-1CSXHC) paired with below Indoor units.
— One 9K wall mounted unit with 30ft refrigerant pipe — One 18K Cassette unit with 30ft refrigerant pipe. — One 24K wall mounted unit with 50ft refrigerant pipe. 1. Step1: Calculate the “Estimated” refrigerant charge. Please note this value
is only used to calculate the additional refrigerant charge amount. Estimated Refrigerant Charge Amount = 98ft 0.16oz/ft. = 15.68oz 2. Step2: Calculate the required charge amount for each zone. Refer to table 8 for Indoor unit liquid line size Zone 1: 24K wall mounted Indoor unit
— Zone 1 Charge Amount = 50ft 0.32oz/ft. = 16oz Zone 2: 18K Cassette Indoor unit
— Zone 2 Charge Amount = 30ft 0.16oz/ft. = 4.8oz Zone 3: 9K wall mounted Indoor unit
— Zone 3 Charge Amount = 30ft * 0.16oz/ft. = 4.8oz Total Zone Charge Amount = 16oz + 4.8oz + 4.8oz = 25.6oz
3. Step3: Calculate the additional refrigerant needed Additional Refrigerant Amount = 25.6oz ­ 15.68oz = 9.92oz

13 Features and Operation
13.1 Protection of the Air Conditioner
Compressor protection Compressor Anti Short Cycle = 3 minutes
Anti-cold air The unit is designed not to blow cold air on HEAT mode, when the indoor unit evaporator coil is in one of the following three conditions and the set temperature has not been reached.
A) When heating has just started B) During defrost cycle C) Low temperature heating
Defrost Cycle Frost may be generated on the outdoor unit during a heat cycle when outdoor temperature is low and humidity is high resulting in lower heating efficiency in the air conditioner.
Under these conditions, the air conditioner will stop heating operations and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes, depending the outdoor temperature and the amount of frost buildup on the outdoor unit.
Auto-Restart In case of power failure, the system will immediately stop. When power returns, the unit will restart with the same settings as before it lost power.
13.2 Operation
White mist emerging from the indoor unit A white mist may be generated due to a large temperature difference between air inlet and air outlet on COOL mode in places with high relative humidity.
A white mist may be generated due to moisture created in the defrosting process when the air conditioner restarts in HEAT mode operation after defrosting.
Noise coming from the air conditioner You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is refrigerant equalizing which is normal.
A low hissing sound may be heard due to the louver restoring itself to its original
position when power is first turned on.
Dust blowing out from the indoor unit. This happens when the air conditioner has not been used for a long time or during its first use.
The air conditioner turns to FAN ONLY mode during COOL or HEAT mode. When the indoor temperature reaches the set temperature setting, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode past the set point. Moisture may form on the surface of the indoor unit when cooling occurs in relatively high humidity (generally higher than 80% relative humidity). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed to reduce and eliminate moisture.

Operation mode selection While two or more indoor units are simultaneously operating, make sure the heat or cool modes do not conflict with each other. The heat mode claims precedence over cooling mode. If the unit initially started to operate in HEAT mode, the other units can operate in HEAT mode only. For example: If the unit initially started operates under COOL mode, other units cannot operate in heat mode. If one of the unit selects HEAT mode while the others are in cool mode, the other operating units will stop operation and display error code.
Optimal operation To achieve optimal performance, please note the following: Adjust the direction of the air flow so that it is not blowing directly on
people.
Adjust the temperature to achieve the highest possible level of comfort. Do not adjust the unit to excessive temperature levels.
Close doors and windows in COOL mode or HEAT mode.
Use the TIMER ON button on the remote controller to select a time you want to start your air conditioner.
Do not place any object near the air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running.
Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
Do not operate unit with horizontal louver in closed position.

14.1 Common Issues
System Failure: Most of the following problems are not a malfunction, but please contact an Authorized Service Provider if the problem is uncertain.

If a problem persists, contact a local dealer or your nearest customer service center. Provide them with a detailed description of the unit malfunction as well as your model number.

Issue Not heating or cooling
The unit changes from COOL/HEAT mode to FAN mode
The indoor unit emits white mist Both the indoor and outdoor units emit white mist The indoor unit makes noises
Both the indoor unit and outdoor unit make abnormal sound
The outdoor unit makes noises Dust is emitted from either the indoor or outdoor unit The unit emits a bad odor The outdoor unit fan does not operate Operation is erratic, unpredictable, or unit is unresponsive Table 13

Possible Causes
The Unit has a 3-minute protection feature that prevents the outdoor unit from short cycling. Heating or cooling will not start until the 3 minute anti short cycle has expired.
The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
In high humidity conditions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
A rushing air sound may occur when the louver resets its position. A squeaking sound may occur after running the unit in HEAT mode due to expansion & contraction of the unit’s plastic parts.
Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant equalization.
Abnormal sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.
The unit will make different sounds based on its current operating mode.
The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is initially operated. This can be mitigated by covering the unit during long periods of inactivity.
The air filter require’s cleaning.
During heating or cooling operation, the fan speed is controlled to optimize product operation.
Interference from cell phone towers and remote boosters may cause the unit to malfunction. In this case, try the following: Disconnect the power, then reconnect. Press ON/OFF button on remote control to restart operation.
