Installing the unit Moving the outdoor unit ENGLISH ffSelect the moving route in advance. ffBe sure that moving route is safe from weight of the outdoor unit. ffDo not slant the product more than 30˚when carrying it. (do not lay the product down sideways) ffThe surface of the heat exchanger is sharp. Be carefule not to be injured while moving and installing. Moving the outdoor unit by wire rope ffFasten the outdoor unit by two 8m or longer wire ropes as shown at the figure.
Installing the unit Deciding on where to install the outdoor unit Decide the installation location regarding the following condition and obtain the user’s approval. ffThe outdoor unit must not be placed on its side or upside down, as the compressor lubrication oil will run into the cooling circuit and seriously damage the unit. ffChoose a location that is dry and sunny, but not exposed to direct sunlight or strong winds. ffDo not block any passageways or thoroughfares.
CAUTION CAUTION Do not install the outdoor unit in a snowy and cold area (low temperature and high humidity area - where the temperature is below -7°C and humidity is higher than 85%) because according to operation condition (defrost, etc.), ice may be formed in the drain route. If the ice is accumulated, it may cause critical damage to the product. ex) lakeside of cold area in winter time, seashore, alpine region and etc. ENGLISH ffDo not install the Air to Water Heat Pump in following places.
Installing the unit Space requirements for outdoor unit When installing 1 outdoor unit ❋❋ When the air outlet is towards the wall 2,000 or more 600 or more 300 or more ❋❋ The upper part of the outdoor unit and the air outlet is towards the wall 1,500 or more 600 or more ❋❋ When 3 sides of the outdoor unit are blocked by the wall 300 or more 300 or more 1,500 or more 300 or more ❋❋ When the air outlet is opposite the wall 1,500 or more 300 or more (Unit : mm) ❋❋ The upper part of the outdoor
When installing more than 1 outdoor unit ENGLISH 1500 or more (Unit : mm) 300 or more ❋❋ When the air outlet is towards the wall 300 or more 600 or more 600 or more 600 or more 600 or more 600 or more ❋❋ When front and rear side of the outdoor unit is towards the wall 1500 or more 600 or more 3000 or more 3000 or more 500 or more 300 or more 500 or more 1500 or more 300 or more ❋❋ When 3 sides of the outdoor unit are blocked by the wall 300 or more ❋❋ The upper part of the outdoor un
Installing the unit Outdoor unit installation The outdoor unit must be installed on a rigid and stable base to avoid any increase in the noise level and vibration, particularly if the outdoor unit is to be installed in a location exposed to strong winds or at a height, the unit must be fixed to an appropriate support(wall or ground). ffFix the outdoor unit with anchor bolts.
Drain work While Air-Water Heat Pump is running in heating mode, Ice can begin accumulate on the surface of condenser. To prevent Ice from growing, system go into De-frost mode and then Ice on the surface changes to water. Dropped water from condenser shall be eliminated through running drain holes to prevent Ice growing at low temperature. WARNING ≥100mm ENGLISH ffIn case there is not enough space for drainage out of the unit, additional drain works are required.
Installing the unit Selecting a location in cold climates NOTE • When operating the unit in a low outdoor ambient temperature, be sure to follow the instructions described below. ffTo prevent exposure to wind, install the unit with its suction side facing the wall. ffNever install the unit at a site where the suction side may be exposed directly to wind. ffTo prevent exposure to wind, install a baffle plate on the air discharge side of the unit.
Piping work CAUTION ENGLISH Water connections must be made in accordance with the outlook diagram delivered with the unit, respecting the water in- and outlet. If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit: ffUse clean pipes only. ffHold the pipe end downwards when removing burrs. ffCover the pipe end when inserting it through a wall so that no dust and dirt enter.
Piping work CAUTION • Before installing/commissioning the unit, make sure to check the following points : -- The maximum water pressure of the unit is 2.8 bar static pressure. -- The operating range of water temperature is 15~55˚C at heating conditions and 5~25˚C at cooling conditions. -- The minimum required water flow for operation is 16 liters/min. At all times the required water flow-rates should remain. Otherwise, the unit can stop due to a lack of water.
Freeze protection Frost can make some damage on the hydraulic system. It is because it is installed outside house nomally. To avoid taking risks of freezing problem, special cares such as Anti-freezing fluid are required as below. Ethylene glycol concentration can vary depeding on outdoor temperature where our system is installed, fill in Ethylene glycol by mixing as below.
Piping work Unit resistance and PHE resistance by glycol concentrate The unit is composed of water pipes and PHE basically. To ensure correct operation and predict the expected performance, Flow and Resistance table can be used and Flow and Resistance characteristic is dependent on Glycol concentration.
Flow switch Flow switch is not integrated part in MONO Unit. But the installation is essential to operate MONO Unit. Flow switch is provided by Samsung control kit as a sub component. CAUTION ENGLISH • Flow switch shall be installed described by installation manual of Mono unit or Control kit. • All electric wiring works shall be implemented by manuals which Samsung provided.
Piping work Pressure relief valve MONO Unit does not have a pressure relief valve. The valve shall prevents abnomal water pressure from damaging the the system by opening at 3.0 bar. • Make certain that the discharged water out of drain pan does not affect other elements. CAUTION Filter / Strainer Installation of Filter / Strainer is mandatory for water system. The Filter or Strainer shall be located in front of inlet pipe of PHE.
Wiring CAUTION • During the unit installation make first refrigerant connections and then electrical connections. If unit is uninstalled first disconnect electrical cables, then refrigerant connections. • Connect the air conditioner to grounding system before performing the electrical connection. • When installing the unit, you shouldn't use inter connection wire.
