Selection guide (YLCA and YLHA PLUS) Necessary information The following information is needed to select a YLCA water chiller: 1. Cooling capacity needed. 2. Design cold water input and output temperatures. 3. Design water flow, if any of the temperatures in above point 2 is unknown. 4. Design input temperature of air to the condensing unit. Normally, this will be the design ambient temperature of summer air, unless influenced by the situation or other factors. 5. Altitude above sea level. 6.
All values are within operating limits. - Available pressure in hydraulic circuit of a unit with hydro kit. - From Table 6 we infer that the YLHA PLUS 5, with a 748 l/h flow, has an available pressure of 56.5 kPa. - Pressure drop in filter. - From Table 7.1" filter, we infer that with a 748 l/h flow, said filter has a pressure drop of 1.2 kPa.

Installation instructions Inspection Upon reception, inspect the goods and notify the carrier and the insurance company, in writing, of any possible damage during transportation. Environmental protection Packing Packing is made of recyclable material. Its elimination should be carried out in accordance with local regulations on selective collection of residual material. Refrigerant Contains greenhouse effect fluorided gas covered by the Kyoto protocol.
Location Before locating the unit, make sure you have received the appropriate product by checking the specifications described on the outside of same. The unit should be placed on a perfectly horizontal plane, making sure the base can support the weight of the unit. If vibration-free operation is required, the unit can be placed on a cork or similar anti-vibratory base, or fastened to the base with anti-vibratory plates or supports. Location of several units Avoid the recirculation of air between units.
Wiring Electrical connections All established national regulations should be complied. Each unit is supplied with a control box to which the power supply will be connected through a fused main switch or an automatic switch. WARNING order detector, when starting the equipment make sure the rotational direction is correct. If it is not correct: - The compressor does not compress. - It makes a strange sound. - Amperage consumption is limited. - It overheats in excess.
