Outdoor unit installation Fix the outdoor unit with anchor bolts. (Unit : mm) Anchor bolt hole 328 • When tightening the anchor bolt Tighten the rubber washer to prevent the outdoor unit bolt connection part from corroding • Make a drain outlet around the base for outdoor unit drainage. • If the outdoor unit is installed on the roof, you have to check the ceiling strength and waterproof the unit. 384 330 • The anchor bolt must be 20mm or higher from the base surface.
Installing the Unit Drain work While Air-Water Heat Pump is running in heating mode, Ice can begin accumulate on the surface of condenser. To prevent Ice 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. ≥100mm In case there is not enough space for drainage out of the unit, additional drain works are required.
Selecting a location in cold climates ENGLISH • When operating the unit in a low outdoor ambient temperature, be sure to follow the instructions described below. To prevent exposure to wind, install the unit with its suction side facing the wall. Never install the unit at a site where the suction side may be exposed directly to wind. To prevent exposure to wind, install a baffle plate on the air discharge side of the unit.
Piping Work 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: Use clean pipes only. Hold the pipe end downwards when removing burrs. Cover the pipe end when inserting it through a wall so that no dust and dirt enter.
Flushing and air-purging 6. Circulate for long enough to ensure that all air has been bled from the complete water piping system. • After installations, commissioning should be performed by qualified representatives. Unless flushing and air-purging works are performed adequately, it might result in malfunctions. Flushing unit (or purging cart) 23 ENGLISH When filling water, the following start-up procedure should be followed. 1. All system components and pipes must be tested for the presence of leaks.
Piping Work 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 12~16 liters/min. At all times the required water flow-rates should remain. Otherwise, the unit can stop due to a lack of water.
Setting capacity and pre-pressure of the expansion vessel ENGLISH When it is required to change the default pre-pressure of the expansion vessel(1 bar), keep in mind the following guidelines: Use only dry nitrogen to set the expansion vessel pre-pressure. Inappropriate setting of the expansion vessel pre-pressure will lead to malfunction of the system. Therefore, the pre-pressure should only be adjusted by a licensed installer. Pre-pressure(bar) 2.5 2.0 1.5 Operation range 1.0 0.5 0.
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 on Glyco concentrate.
Charging Water ENGLISH After installation is completed, the following procedures shall be used to charge water into the hydro unit. Connect water lines to water connections of Air-Water Heat Pump. Air vent valve shall be open at least 2turns so that air can be eliminated in the system. Open the service valve in the water supply connection. Water pressure of supply line shall be over 2.0 bar for good charging work. Stop water supply when the pressure gauge of hydro unit indicates around 2.
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. 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.
AA Wiring • 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.
