2.4. Suspension structure (Give site of suspension strong structure) (Fig. 2-4)

• The ceiling work differs according to the construction of the building. Building constructors and interior decorators should be consulted for details.

(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and the ceiling foundation (framework: wooden slats and slat holders) must be reinforced in order to protect the ceiling from vibration.

(2) Cut and remove the ceiling foundation.

(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceiling foundation for securing the ends of the ceiling board.

(4) When installing the indoor unit on a slanted ceiling, attach a pillar between the ceiling and the grille and set so that the unit is installed horizontally.

1 Wooden structures

• Use tie beams (single storied houses) or second floor beams (two story houses) as reinforcing members.

• Wooden beams for suspending air conditioners must be sturdy and their sides must be at least 6 cm long if the beams are separated by not more than 90 cm and their sides must be at least 9 cm long if the beams are separated by as much as 180 cm. The size of the suspension bolts should be ø10 (3/8"). (The bolts do not come with the unit.)

2 Ferro-concrete structures

• Secure the suspension bolts using the method shown, or use steel or wooden hangers, etc. to install the suspension bolts.

2.5. Unit suspension procedures (Fig. 2-5)

Suspend the main unit as shown in the diagram.

Figures given in parentheses represent the dimensions in case of installing optional multi function casement.

1. In advance, set the parts onto the suspension bolts in the order of the washers

(with insulation), washers (without insulation) and nuts (double).

• Fit the washer with cushion so that the insulation faces downward.

• In case of using upper washers to suspend the main unit, the lower washers (with insulation) and nuts (double) are to be set later.

2. Lift the unit to the proper height of the suspension bolts to insert the mounting plate between washers and then fasten it securely.

3. When the main unit can not be aligned against the mounting hole on the ceiling, it is adjustable owing to a slot provided on the mounting plate.

• Make sure that A is performed within 17-22 mm. Damage could result by failing to adhere to this range. (Fig. 2-6)

Caution:

Use the top half of the box as a protective cover to prevent dust or debris from getting inside the unit prior to installation of the decorative cover or when applying ceiling materials.

2.6. Confirming the position of main unit and tightening the suspension bolts (Fig. 2-7)

• Using the gauge attached to the grille, ensure that the bottom of the main unit is properly aligned with the opening of the ceiling. Be sure to confirm this, otherwise condensation may form and drip due to air leakage, etc.

• Confirm that the main unit is horizontally levelled, using a level or a vinyl tube filled with water.

• After checking the position of the main unit, tighten the nuts of the suspension bolts securely to fasten the main unit.

• The installation template (top of the package) can be used as a protective sheet to prevent dust from entering the main unit when the grilles are left unattached for a while or when the ceiling materials are to be lined after installation of the unit is finished.

4. Connecting water pipes

Please observe the following precautions during installation.

4.1. Important notes on water pipework installation

• The water pressure resistance of the water pipes in the heat source unit is 1.0MPa

[145psi].

• Please connect the water pipework of each indoor unit to the connect port on the

HBC. Failure to do so will result in incorrect running.

• Please list the indoor units on the naming plate in the HBC unit with addresses and end connection numbers.

• If the number of indoor units are less than the number of ports on the HBC, the unused ports can be capped. Without a cap, water will leak.

• Use the reverse-return method to insure proper pipe resistance to each unit.

• Provide some joints and bulbs around inlet/outlet of each unit for easy maintenance, checkup, and replacement.

• Install a suitable air vent on the water pipe. After flowing water through the pipe, vent any excess air.

• Secure the pipes with metal fitting, positioning them in locations to protect pipes against breakage and bending.

• Do not confuse the water intake and outlet piping. Error code 5102 will appear on the remote controller if a test run is performed with the pipe-work installed incorrectly

(inlet connected to outlet and vice versa).

• This unit doesn’t include a heater to prevent freezing within tubes. If the water flow is stopped on low ambient, drain the water out.

• The unused knockout holes should be closed and the refrigerant pipes, water pipes, power source and transmission wires access holes should be filled with putty.

• Install water pipe so that the water flow rate will be maintained.

• Wrap sealing tape as follows.

1

Wrap the joint with sealing tape following the direction of the threads (clockwise), do not wrap the tape over the edge.

2 Overlap the sealing tape by two-thirds to three-fourths of its width on each turn.

Press the tape with your fingers so that it is tight against each thread.

3 Do not wrap the 1.5th through 2nd farthest threads away from the pipe end.

B Water pipe: From HBC unit

• Hold the pipe on the unit side in place with a spanner when installing the pipes or strainer. Tighten screws to a torque of 40 N·m.

• If there is a risk of freezing, carry out a procedure to prevent it.

• When connecting heat source unit water piping and on site water piping, apply liquid sealing material for water piping over the sealing tape before connection.

• Do not use steel pipes as water pipes.

- Copper pipes are recommended.

• Install a strainer (40 mesh or more) on the pipe next to the valve to remove the foreign matters.

• Be sure to provide anti-dew condensation treatment on the inlet and outlet of the water pipes and on the valve. Provide an appropriate treatment on the end surface of the dew proofing material to keep condensation out.

• When water has been supplied to the water pipework, purge the system of air.

The details of air purging can be found separately in the water circuit maintenance manual.

4.2. Water pipe insulation

1. Connect the water pipes of each indoor unit to the same (correct) end connection numbers as indicated on the indoor unit connection section of each HBC controller.

If connected to wrong end connection numbers, there will be no normal operation.

2. List indoor unit model names in the name plate on the HBC controller control box

(for identification purposes), and HBC controller end connection numbers and address numbers in the name plate on the indoor unit side.

Seal unused end connections using cover caps (sold separately). Not replacing on end cap will lead to water leakage.

3. Be sure to add insulation work to water piping by covering water pipework separately with enough thickness heat-resistant polyethylene, so that no gap is observed in the joint between indoor unit and insulating material, and insulating materials themselves. When insulation work is insufficient, there is a possibility of condensation, etc. Pay special attention to insulation work in the ceiling plenum.

[Fig.4-1]

• Insulation materials for the pipes to be added on site must meet the following specifications:

HBC controller

-indoor unit

20 mm or more

• This specification is based on copper for water piping. When using plastic pipework, choose a thickness based on the plastic pipe performance.

• Installation of pipes in a high-temperature high-humidity environment, such as the top floor of a building, may require the use of insulation materials thicker than the ones specified in the chart above.

• When certain specifications presented by the client must be met, ensure that they also meet the specifications on the chart above.

4. Leakproof the water pipework, valves and drain pipework. Leakproof all the way to, and include pipe ends so that condensation cannot enter the insulated pipework.

5. Apply caulking around the ends of the insulation to prevent condensation getting between the pipework and insulation.

6 Add a drain valve so that the unit and pipework can be drained.

7. Ensure there are no gaps in the pipework insulation. Insulate the pipework right up to the unit.

8. Ensure that the gradient of the drain pan pipework is such that discharge can only blow out.

4.3. Water treatment and quality control

To preserve water quality, use the closed type of water circuit. When the circulating water quality is poor, the water heat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion. Pay careful attention to water processing and water quality control when installing the water circulation system.

• Removing of foreign objects or impurities within the pipes.

During installation, make sure that foreign objects, such as welding fragments, sealant particles, or rust, do not enter the pipes.

• Water Quality Processing

1 Depending on the quality of the cold-temperature water used in the airconditioner, the copper piping of the heat exchanger may corrode.

Regular water quality processing is recommended.

If a water supply tank is installed, keep air contact to a minimum, and keep the level of dissolved oxygen in the water no higher than 1mg/ℓ.

3 Consult with a specialist about water quality control methods and calculations before using anti-corrosive solutions.

4 When replacing a previously installed air conditioning device (even when only the heat exchanger is being replaced), first conduct a water quality analysis and check for possible corrosion.

Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion.

If the water quality level has dropped, adjust water quality before replacing the unit.
