1. The circuit incorporates a capillary tube which controls the refrigerant flow to the evaporator A filter dryer is provided in the liquid line to eliminate all moisture for maximum efficiency and an increased working life The compressor is equipped with two pressure switches for protection against high condensing and low evaporating pressures The low pressure switch features automatic reset and a delay for winter operation whilst to avoid compressor cycling at high discharge pressures The high pressure switch is equipped with manual reset 1 5 Evaporating section Cooling capacity 1 5 1 Heat transfer coil This consists of a plate coil in copper tubes with aluminium fins and with a large face area so as to increase the SHR and optimise the EER this is achieved by reducing the air pressure drop and turbulence and increasing the evaporating temperature thus the efficiency of the compressor A galvanized steel basin is provide for the drainage water page 2 of 12 English Hiline Slim Operation diagram Hiline Slim PKS3 AIR CONDITIONING FREECOOLING ECONOMIC COOLING 5 10 5 10 INSIDE INSIDE OUTSIDE q 1 6 11 7 7 8 8 9 9 10 10 13 13 E COOLED AIR 8 gt FREECOLING AIR C gt CONDENSER SECTION AIR gt AIR TO BE COOLED POS DESCRIPTION POS DESCRIPTION 1 Air filter 8 Condensate drain tank 2 Damper motor 9 Compressor 3 Electronic control2. 10 Condenser fan 4 Electrical board 11 Condenser 5 Evaporator 12 Freecooling damper 6 Evaporator fans 13 Condensate drain H Electric heaters optional 14 Supply cable inlet page 3 of 12 Hiline Slim English 1 5 2 Fan features The units are equipped with three awial fans with integral motor and individual thermal protection The ig impellers are statically and dynamically balanced with e lifetime lubricated bearings for quiet vibration free E Operation e The motor is single phase IP23 B class insulation M L so 2 40 o 30 20 10 Duo 0 10 0 20 0 30 0 40 0 50 Airflow m3 s Standard fan section available external static pressure 1 6 Condensing section Reliability 1 6 1 Heat transfer coil The air condensing coil is designed in rolled copper tubes with turbulence enhancing aluminium fins and sized to allow operations up to 45 C outdoor air temperature 1 6 2 Fan features The units are equipped with two compact axial fans with integral motor and individual thermal protection IP44 F class An On Off pressostat acting on the fans keeps the condensing pressure and temperature into the normal range 1 7 Air filter section Air Purity The filter section is placed vertically before the evaporating coil and provides filtration of the recirculated or the fresh
