3 English2-2 Standard operation limitThe figures below assume following operating conditions for indoorand outside units:Equivalent pipe length .....................................................7.5mLevel difference ..................................................................0mCooling HeatingA Inlet water temperature (°C)B Indoor temperature (°CWB)C Indoor temperature (°CDB)Range for continuous operationRange for operationRange for pull down operationRange for warming up operation• Operation range of water volume is 50-150L/min• The unit is designed for the following operation range:Water temperature: 20-35°CWater volume: 60 L/minute or more• During cooling operation when the outside temperature is verylow, it is possible that the thermostat switches off automatically inorder to protect the unit from freezing.• Hold ambient temperature at 0-40°CHeat-release from the unit: 0.71 kW/10Hp/hour.It is therefore recommended to always ventilate the room.2-3 Standard supplied accessories• Make sure that the following accessories are included.(Check by removing the front panel.)(Refer to figure 1)1. • Operation manual• Installation manual• Declaration of conformity• Clamp (A)• Clamp (B)2. • Accessory pipe (1)• Accessory pipe (2)• Accessory pipe (3)NoteThe accessory pipe (1), (3) is not used for the heat pump system.2-4 Option accessoryTo install the above outside units, the following optional parts are alsorequired.• Refrigerant branching kit(For R410A only: Always use an appropriate kit dedicated for yoursystem.)〈Heat pump system〉〈Heat recovery system ..... For 3-tube piping〉〈Heat recovery system ..... For 2-tube piping〉• Outside unit multi connection piping kit(For R410A only: Always use an appropriate kit dedicated foryour system.)∗ To select an optimum kit, refer to “9. REFRIGERANT PIPING”2-5 Technical and electrical specificationsRefer to the Engineering Data Book for the complete list of specifica-tions.3. SELECTION OF LOCATIONThis unit does not have specifications for outdoor installation.The unit must be installed indoors (example: machine room, …)Always install it in a room.(machine room, etc.)Paying attention to the conditions mentioned below, select the placefor installation with a prior approval of customer.1. The foundation is strong enough to support the weight of the unitand the floor is flat to prevent vibration and noise generation.2. Consider the space required for refrigerant piping work wheninstalling. Refer to [Necessary Space].3. There is no danger of fire due to leakage of inflammable gas.4. The piping length between the outside unit and the indoor unitmay not exceed the allowable piping length. “9. REFRIGERANTPIPING”.5. Locations where the noise of the unit operating will not disturbnearby houses, etc.6. Locations with airflow and ventilation holes capable of dissipatingheat from the machine and where the ambient temperaturearound the outside unit is between 0 and 40°C and the humiditydoes not exceed 80%.[Necessary Space]When installing, secure the space mentioned below without fail.(Refer to figure 2)1. In case of a single installation [mm]2. In case of series installations [mm]3. Top view4. Side view5. Outside unit6. Service Space (front side)7. Service Space (back side)8. Space for installing water piping∗Secure a enough space for removing the front panel.9. Ventilation Space∗above the area ( ) of the outside unit.10. Secure spaces in the front, back and top sides as sameas the case of single installation.Caution1. An inverter air conditioner may cause electronic noise gener-ated from AM broadcasting. Examine where to install the mainair conditioner and electric wires, keeping proper distancesaway from stereo equipment, personal computers, etc.(Refer to figure 3)1. Indoor unit2.
