Page 10: Compressor Assembly
4 | Compressor assembly INFO New compressors are factory-filled with inert gas. Leave this ser- vice charge in the compressor for as long as possible and prevent the ingress of air. Check the compressor for transport damage before starting any work. 4.1 Storage and transport Storage at (-30 °C) - (+70 °C), maximum permissible relative humidity 10 % - 95 %, no condensation... -
Page 11: Setting Up
4 | Compressor assembly 4.2 Setting up ATTENTION Attachments (e.g. pipe holders, additional units, fastening parts, etc.) directly to the compressor are not permissible! Provide adequate clearance for maintenance work. Provide adequate ventilation for the drive motor. Fig. 12 Do not use in a corrosive, dusty, damp atmosphere or a combustible environment. -
Page 12: Pipe Connections
4 | Compressor assembly 4.4 Pipe connections ATTENTION Risk of damages. Overheating can damage the valve. Remove the pipe supports from the valve for soldering. Only solder using inert gas to inhibit oxidation products (scale). The pipe connections have stepped internal diameters so that pipes with standard millimetre and inch dimensions can be used. - Page 13 4 | Compressor assembly Solenoid valve dead Non-return valve open Fig. 18 Important: Start unloader may only be employed during the starting phase. Check the solenoid valve and the non-return valve regularly for tightness. In addition, we recommend to use a heat protection thermostat on the discharge side of the com- pressor.

Page 16: Preparations For Start-Up
5 | Commissioning 5.1 Preparations for start-up INFO To protect the compressor against inadmissible operating conditions, high pressure and low pressure pressostats are mandatory on the installation side. The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions. -
Page 17: Refrigerant Charge
5 | Commissioning 5.5 Refrigerant charge CAUTION Risk of injury! Contact with refrigerant can cause severe burns and skin damage. Avoid contact with refrigerant and wear personal protective clothing such as goggles and protective gloves! Make sure that the suction and discharge line valves are open. With the compressor switched off, add the liquid refrigerant directly to the condenser or receiver, breaking the vacuum. -
Page 18: Start-Up
5 | Commissioning 5.7 Start-up WARNING Ensure that both shut-off valves are open before starting the compressor! Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are all functioning properly. Switch on the compressor and allow to run for a minimum of 10 min. Check the oil level by: The oil must be visible in the sight glass. -
