Safety Notices

WARNING

Mechanical

The hydrobox and outdoor units must not be installed, disassembled, relocated, altered or repaired by the user. Ask an authorised installer or technician. If the unit is installed improperly or modied after installation by the user water leakage, electric shock or re may result.

The outdoor unit should be securely xed to a hard level surface capable of bearing its weight. The hydrobox should be positioned on a hard vertical surface capable of supporting its lled weight to prevent excessive sound or vibration. Do not position furniture or electrical appliances below the outdoor unit or hydrobox. The discharge pipework from the emergency/safety devices of the hydrobox should be installed according to local law. Only use accessories and replacement parts authorised by Mitsubishi Electric ask a qualied technician to t the parts.

Electrical

All electrical work should be performed by a qualied technician according to local regulations and the instructions given in this manual. The units must be powered by a dedicated power supply and the correct voltage and circuit breakers must be used. Wiring should be in accordance with national wiring regulations. Connections must be made securely and without tension on the terminals. Earth unit correctly.

General

Keep children and pets away from both the hydrobox and outdoor units. Do not use the hot water produced by the heat pump directly for drinking or cooking. This could cause illness to the user. Do not stand on the units. Do not touch switches with wet hands. Annual maintenance checks on both the hydrobox and the outdoor unit should be conducted by a qualied person. Do not place containers with liquids on top of the hydrobox. If they leak or spill onto the hydrobox damage to the unit and/or re could occur. Do not place any heavy items on top of the hydrobox. When installing, relocating, or servicing the hydrobox, use only the specied refrigerant (R410A) to charge the refrigerant lines. Do not mix it with any other refrigerant

and do not allow air to remain in the lines. If air is mixed with the refrigerant, then it can be the cause of abnormal high pressure in the refrigerant line, and may result in an explosion and other hazards. The use of any refrigerant other than that specied for the system will cause mechanical failure or system malfunction or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.

In heating mode, to avoid the heat emitters being damaged by excessively hot water, set the target ow temperature to a minimum of 2ºC below the maximum allowable temperature of all the heat emitters. For Zone2, set the target ow temperature to a minimum of 5ºC below the maximum allowable ow temperature of all the heat emitters in Zone2 circuit.

Do not install the unit where combustible gases may leak, be produced, ow, or accumulate. If combustible gas accumulates around the unit, re or explosion may result.

CAUTION

Use clean water that meets local quality standards on the primary circuit. The outdoor unit should be installed in an area with sufcient airow according to the diagrams in the outdoor unit installation manual. The hydrobox should be located inside to minimise heat loss. Water pipe-runs on the primary circuit between outdoor and indoor unit should be kept to a minimum to reduce heat loss. Ensure condensate from outdoor unit is piped away from the base to avoid puddles of water. Remove as much air as possible from water circuit. Refrigerant leakage may cause suffocation. Provide ventilation in accordance with EN378-1. Be sure to wrap insulation around the piping. Direct contact with the bare piping may result in burns or frostbite. Never put batteries in your mouth for any reason to avoid accidental ingestion. Battery ingestion may cause choking and/or poisoning. Install the unit on a rigid structure to prevent excessive sound or vibration during operation. If power to the hydrobox is to be turned off (or system switched off) for a long time, the water should be drained. Preventative measures should be taken against water hammer, such as installing a Water Hammer Arrestor on the primary water circuit, as directed by the manufacturer. In order to prevent condensation on emitters, adjust ow temperature appropriately and also set the lower limit of the ow temperature on site.

As for the handling of refrigerant, refer to the outdoor unit installation manual.

Please read the following safety precautions carefully.

WARNING:

Precautions that must be observed to prevent injuries or death.

CAUTION:

Precautions that must be observed to prevent damage to unit.

This installation manual along with the user manual should be left with the product after installation for future reference. Mitsubishi Electric is not responsible for the failure of locally-supplied parts.

• Be sure to perform periodical maintenance.

• Be sure to follow your local regulations.

• Be sure to follow the instructions provided in this manual.

The purpose of this installation manual is to instruct competent persons how to safely and efficiently install and commission the hydrobox system. The target readers of this manual are competent plumbers and/or refrigeration engineers

Note

• Be sure to follow your local regulations to perform system conguration of the DHW connections.

• DHW connections are not included in the hydrobox package. All required parts are to be sourced locally.

• To enable draining of the hydrobox an isolating valve should be positioned on both the inlet and outlet pipework.

• Be sure to install a strainer on the inlet pipe work to the hydrobox.

• Suitable drain pipework should be attached to all relief valves in accordance with your country's regulations.

• A backow prevention device must be installed on water supply pipework (IEC 61770).

• When using components made from different metals or connecting pipes made of different metals insulate the joints to prevent a corrosive reaction taking place which will damage the pipework.

Energy monitor

End user can monitor accumulated*1 ‘Consumed electrical energy’ and ‘Delivered heat energy’ in each operation mode*2 on the main remote controller. *1 Monthly and Year to date *2 - DHW operation

- Space heating

- Space cooling

Refer to “5.10 Main remote controller” for how to check the energy, and “5.1 DIP switch functions” for the details on DIP-SW setting. Either one of the following two method is used for monitoring.

Note: Method 1 should be used as a guide. If a certain accuracy is required, the 2nd method should be used.

1. Calculation internally Electricity consumption is calculated internally based on the energy consumption of outdoor unit, electric heater, water pump(s) and other auxiliaries. (*3) Delivered heat is calculated internally by multiplying delta T (Flow and Return temp.) and flow rate measured by the factory fitted sensors. Set the electric heater capacity and water pump(s) input according to indoor unit model and specs of additional pump(s) supplied locally. (Refer to the menu tree in “5.10 Main remote controller”)

4.2 Water Quality and System Preparation

General

•

The water in both primary and sanitary circuit should be clean and with pH value of 6.5-8.0.

• The followings are the maximum valves;

Calcium: 100mg/L, Ca hardness: 250mg/L Chlorine: 100mg/L, Copper: 0.3mg/L Iron/Manganese: 0.5mg/L

• Other constituents should be to European Directive 98/83 EC standards.l

• In known hard water areas, to prevent/minimise scaling, it is benecial to restrict

the routine stored water temperature (DHW max. temp.) to 55°C.

Anti-Freeze

Anti-freeze solutions MUST use propylene glycol with a toxicity rating of Class 1 as

listed in Clinical Toxicology of Commercial Products, 5th Edition.

Note:

1. Ethylene glycol is toxic and must NOT be used in the primary water circuit

in case of any cross-contamination of the potable circuit.

2. For 2-zone valve ON/OFF control, propylene glycol MUST be used.

New Installation (primary water circuit)

• Before connecting outdoor unit, thoroughly cleanse pipework of building debris,

solder etc using a suitable chemical cleansing agent.

• Flush the system to remove chemical cleanser.

• For all packaged model systems, and the split model or PUMY system without

booster heater, add a combined inhibitor and anti-freeze solution to prevent damage to the pipework and system components.

• For split model systems the responsible installer should decide if anti-freeze

solution is necessary for each site’s conditions. Corrosion inhibitor however should always be used.

Existing Installation (primary water circuit)

• Before connecting outdoor unit the existing heating circuit MUST be chemically

cleansed to remove existing debris from the heating circuit.

• Flush the system to remove chemical cleanser.

• For all packaged model systems add a combined inhibitor and anti-freeze

solution to prevent damage to the pipework and system components.

• For split model systems the responsible installer should decide if anti-freeze

solution is necessary for each site’s conditions. Corrosion inhibitor however should always be used.

When using chemical cleansers and inhibitors always follow manufacturer’s instructions and ensure the product is appropriate for the materials used in the water circuit

4.3 Water Pipe Work

Note: Prevent the eld piping from straining the piping on the hydrobox by

xing it to a wall or applying other methods.

Hot Water Pipework

The function of the following safety components of the hydrobox should be checked on installation for any abnormalities;

• Pressure relief valve

• Expansion vessel pre-charge (gas charge pressure)

The instruction on the following pages regarding safe discharge of hot water from Safety devices should be followed carefully.

• The pipework will become very hot, so should be insulated to prevent burns.

• When connecting pipework, ensure that no foreign objects such as debris or the

like do not enter the pipe.

Hydraulic Filter Work (ONLY EHPX series)

Install a hydraulic lter or strainer (local supply) at the water intake (“Pipe E” in Table 3.3, also see associated schematic Fig. 3.5)

Pipework Connections

Connections to the hydrobox should be made using the 28 mm compression as appropriate. (except for ERSC series) Do not over-tighten compression ttings as this will lead to deformation of the olive ring and potential leaks.

Note: To weld the pipes in the eld, cool the pipes on the hydrobox using wet

towel etc. ERSC series have G1 (male) thread connections.

Insulation of Pipework

•

All exposed water pipework should be insulated to prevent unnecessary heat loss and condensation. To prevent condensate entering the hydrobox, the pipework and connections at the top of the hydrobox should be carefully insulated.

• Cold and hot water pipework should not be run close together where possible, to avoid unwanted heat transfer.

•

Pipework between outdoor heat pump unit and hydrobox should be insulated with suitable pipe insulation material with a thermal conductivity of ≤ 0.04 W/m.K.
