Page 6: Health & Safety
Health and Safety Important Note: Only a qualified refrigeration engineer, who is familiar with refrigeration systems and components including all controls, should perform the installation and start-up of the system. To avoid potential injury, use care when working around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in accordance with all applicable codes, ordinances and local by-laws. -
Page 7: Installation Unit Location
Installation Unit location In order to achieve maximum cooling capacity, the installation location for the condensing unit should be carefully selected. Install the condensing unit in such a way so that hot air ejected by the condensing unit cannot be drawn in again (short circuit of hot discharge air). -

Page 9: Field Piping
Installation Field piping Important Note: Pipe sizes and maximum lengths/heights should be strictly as per the information given on page 4. All local codes of practice must be observed in the installation of refrigerant piping To ensure satisfactory operation and performance, the following points should be noted for field piping arrangements: ... -
Page 10: Pressure Testing
Installation Pressure testing Both the indoor and outdoor units have been pressure tested in the factory prior to dispatch. The indoor unit contains a holding charge of oxygen free nitrogen. The outdoor unit contains a charge of R410A refrigerant. Important Note: Do not open the service valves on the condensing unit until pressure testing and evacuation procedures have been carried out. -

Page 12: Drainage
Installation Drainage Important Note: The evaporator drain pan fitting is supplied loose and must be fitted on site. It is attached to the indoor unit fan guard with a cable tie. Correct fitting is vital to ensure leak – free operation. The lock nut on the drain fitting must be fitted the right way around;... -
Page 13: Electrical
Installation Electrical Important Note: The mains electrical supply to the indoor unit must be via a suitably rated isolator and motor rated circuit breaker or fuse. There is no isolator fitted to either the indoor or the outdoor unit. The rocker switch on the front of the indoor unit is for isolating the indoor fan and electronic controller only. -
Page 14: Commissioning
Installation Commissioning Important Note: Before starting the system, ensure that all electrical connections are correctly made and tight, service ports are in the correct position and all covers and guards are fitted. Switch on the power at the mains isolator and then switch on the rocker switch on the front of the indoor unit. Set the required operating temperature on the electronic controller and check the system parameters in the controller are as required (the controllers are pre- programmed in the factory to suggested settings). -
Page 15: Service & Maintenance
Service & Maintenance Important Note: Warning! – Disconnect the mains electrical supply before servicing or opening the units. The units are designed to give long life operation with minimum maintenance. However, they should be routinely checked and the following service schedule is recommended under normal circumstances: Indoor and Outdoor units –... -
Page 16: F-Gas Information
F-Gas Information From 1/1/2015, a new F-Gas Regulation (EC 517/2014) comes into force replacing the old Regulation (EC 842/2006. This will affect system labelling, information supplied within documentation and also the way in which thresholds for frequency of leak testing refrigeration systems are calculated. -
