(See figure) 20 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. In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is not affected by the snow (If necessary construct a lateral canopy). 1. Construct a large canopy. 2 . Construct a pedestal. Install the unit high enough off the ground to prevent it being buried under snow. Considering the direction of strong wind, the outdoor unit shall be installed. Strong wind can make the unit turned over so need to set side of the unit face the direction of wind, not front. Strong wind Strong wind blown air 21 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. Use a good thread sealant for the sealing of the connections The sealing must be able to withstand the pressures and temperatures of the system. When using non-brass metallic piping, make sure to insulate both materials from each other to prevent galvanic corrosion. Because brass is a soft material, use appropriate tooling for connecting the water circuit. Inappropriate tooling will cause damage to the pipes. • • • Be careful not to deform the unit piping by using excessive force when connecting the piping. Deformation of the piping can cause the unit to malfunction. Always use two wrenches (spanners) for tightening or loosening the water connections, and tighten connections with a torque wrench as specified in below table. If not, connections and parts can be damaged and leaks. The unit is only to be used in a closed water system. If applications are in open water circuit, it will generate Heat exchangers fouling, Corrosion, Leak.

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. 2. Preparation of a make-up water assembly or flushing unit is recommended for installation and service. 3. Before connecting pipes to the hydro unit, flush water pipes clean to remove contaminants during hours using a flushing unit or tap water pressure if it is adequate (at 2 to 3 bar) 4. Fill water into the hydro unit by opening service valves. 5. Purge the air. (Fill with a flushing unit with sufficient capacity: avoid aerating the water) 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. - Water quality must be according to EN directive 98/83 EC. - If the unit and the pipes are exposed to freezing temperature, It can cause damage to the hydraulic system. Special care must be taken to prevent freezing of the total water system. - The unit is designed to be used in a closed-loop system. Do not use any other components which are designed only for a open-loop system. - Never use Zn-coated parts in the water circuit. - All hydraulic parts including field piping must be insulated to reduce heat loss and condensation. - It is recommended to install the make-up water assembly to feed small quantities of water to the system automatically, replacing the minor water losses and maintaining the system pressure. - Drain taps must be provided at all low points of the system to permit complete drainage of the circuit for maintenance use. - Make sure that the check valves are correctly installed in the system (field supply). - Flush pipes out with clean water to remove contaminants in pipes during installation. - The strainer(water filter) must be cleaned after flushing the pipes, and it should be cleaned periodically. Replace strainer when necessary. - Charging; Charge the water until a pressure of 1.5~2.0bar by using make-up water assembly(Field supply). (The water pressure indicated on the manometer will vary depending on the water temperature) The nominal water pressure in the system should remain about 1.0 bar at all times to avoid air entering the water system. - Air purging; Make sure that air should be vented from the system at start-up or after installing/ servicing. The air vent valve must be opened during charging the water (at least 2 turns) in order to remove all air in the circuit, and a make-up water assembly allows water into the system continuosly. - In case that the water piping would be located in a higher position than the air vent of the unit, it is necessary to add an additional ones in the highest position of water circuit. The air vent should be located both where water temperatures are the highest and where the height of pipes are the highest. - Always use materials which are compatible with water used in the system and with the materials used on the indoor unit. - Select piping diameter in relation to required water flow and available ESP of the pump. - Use chemical cleaning agents(Begin with acid , finish with alkali). - Do not operate the system with closed valves because it results in damaging the heat pump. 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. Ethylene Glycol Is Toxic Ethylene glycol is toxic if swallowed, and therefore is a hazard to animals and small children. Ethylene glycol must be handled in accordance with relevant local laws and regulations. 24 Outdoor temperature Ethylene Glycol(%) 23°F (–5°C) 10 14°F (–10°C) 20 5°F (–15°C) 25 –10°F (–20°C) 35 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 0.0 150 200 250 300 350 Total water volume(ℓ) Installation height difference (a) <7m >7m Water volume < 220 Litres No pre-pressure adjustment required. Actions required: •P re-pressure must be increased, calculate the appropriate value following by “Calculating the pre-pressure of the expansion vessel”. •C heck if the water volume is lower than maximum allowed water volume > 220 Litres Actions required: •P re-pressure must be decreased, calculate according to “Calculating the pre-pressure of the expansion vessel”. •C heck if the water volume is lower than maximum allowed water volume Expansion vessel of the unit too small for the installation. (a) Installation height difference: height difference(m) between the highest point of the water circuit and the indoor unit. If the unit is located at the highest point of the installation, the installation height is considered 0m.
