Operator section KT series chillers – Installation and Operation manual 1.0 Introduction By selecting a K series chiller you have invested in many years experience in the design and manufacture of precision temperature control instrumentation. ATC has built your K series chiller without compromise to meet the objectives of performance and reliability. Please read this manual carefully to ensure you understand the operation of the machine and how to use the unit safely and efficiently.
Safety For your safety we draw your attention to the following Warning and Caution statements throughout this manual, identified by the symbols… and i respectively. The safe operation of a KT series chiller remains the responsibility of the operator at all times. i Attention: Failure to comply with a Caution will invalidate product warranty and absolve ATC from any liability, howsoever caused, and could result in permanent damage to equipment.
Operator section KT series chillers – Installation and Operation manual 1.1 Warranty registration The warranty registration card must be completed and returned to ATC. This does not affect your statutory rights. 1.2 Unpacking Please check that both the packaging and the unit are undamaged. If there is any doubt, it is vital that you inform both ATC and the carrier before making a claim on the carrier. There are no hidden shipping bolts or other fixings.
KT series chillers – Installation and Operation manual Operator section 1.3 Site requirements · Hard, level surface. · Clean, dust free environment. Air-cooled chillers move large volumes of air, and large amounts of air-borne contamination will result in fouling of the condenser. This will reduce the capacity of the unit and in extreme cases cause a system shutdown. · Non-condensing ambient, from +4°C to +40°C.
KT series chillers – Installation and Operation manual Operator section provide excellent corrosion protection, freeze protection, algae inhibition and good heat transfer properties. i Caution: Always use ATC recommended fluids in your K series chiller. Never use other anti-freeze mixtures, as they may corrode your application and will damage the K series pump seals. All connections should be made using the fittings and clips provided.
Operator section KT series chillers – Installation and Operation manual Chiller filling procedure 1. Check valves in your application are open 2. Remove lid from the coolant reservoir 3. Fill with Hexid to within 40mm (1½ inches) of the tank rim. 4. Switch the unit on. 5. Wait while the fluid level drops in the tank. 6. Switch the unit off. 7. Repeat steps 3 to 5 until all of the air has been purged from the system. 8. Top up to a level 40mm (1½ inches) below the tank rim. 9.
Operator section KT series chillers – Installation and Operation manual 3.0 Operation KTR models only Connect the mains cable and switch the unit on. The neon will illuminate, and the chiller runs automatically. KTR chillers have been configured to provide temperature stability to ±0.2°C, and the actual temperature achieved will be in the range 12°C-20°C, depending on the load and ambient temperature. This model is designed to provide a reliable and inexpensive alternative to tap water.
KTD models only Connect the mains cable and switch the unit on, and after a short self-test, the temperature controller will show coolant temperature. The KTD chiller is fitted with a high performance 3 term PID controller, which is capable of controlling temperature to within 0.1°C of set point.
Fluid flow and pressure KT chillers fitted with a 2 or 3 litre per minute pump are capable of producing up to 150 psi, because of the high pressure volumetric pump. These units are normally supplied factory set to run at an operating pressure of 35 psi, which is suitable for most applications. The pressure setting is controlled by an internal bypass valve, which will open above the preset level to protect your application from higher pressures.
Technician section KT series chillers – Installation and Operation manual 5.0 Technician section Warning: Opening the refrigeration system may expose the operative to toxic and corrosive compounds (HF). Take protective measures including suitable eye protection. Warning: Gases may exceed 300 psi (20 bar) during operation. Warning: All refrigerants do not support combustion and are asphyxiating gases. Warning: After switching off, the condenser cooling fan blades continue to rotate.
i Caution: Changing the flow/pressure with the pressure relief valve will also change the preset pressure safety setpoint. This will move to a lower pressure than the factory setting when decreasing the flow/pressure, and to a higher pressure when increasing the flow/pressure. i Caution: When the flow/pressure is manually increased by the pressure relief valve, the safety provided by the valve will be effected at higher pressures than standard.
Technician section KT series chillers – Installation and Operation manual 5.3 Troubleshooting Symptom Causes Compressor not running, but fan running Is the controller displaying an alarm? If there is no obvious cause, check… · The condenser is clean · Ambient temperature not above 30°C The likely cause is the compressor’s internal protection has been activated and should restart in five minutes.
KT series chillers – Installation and Operation manual 6.0 Warranty terms and conditions i. ATC provides a comprehensive return to base 2 year parts, 1 year labour warranty from delivery as standard on all new K series chillers, provided that they have been installed and operated in accordance with this manual. ii.
