- Page 10 Commissioning Display/ keypad unit (LEDs and button functions) Units with microchannel condenser coils Care must be taken during charging a unit with refrigerant when a microchannel condenser coil is fitted. Because the microchannel coils hold less refrigerant than traditional fin/tube coils, it is easier to overcharge, especially if the system is commissioned during winter time when the ambient temperature is colder.

Page 23: F-Gas Information
F-Gas Information From 1/1/2015, F-Gas Regulation EU 517/2014 came into force replacing the old Regulation EC 842/2006. This affects system labelling, information supplied within documentation and also the way in which thresholds for frequency of leak testing refrigeration systems are calculated. Please be aware of the following: The models of equipment covered in this Technical Manual rely on fluorinated greenhouse gases for their functioning. - Page 24 J & E Hall Limited Hansard Gate West Meadows Derby, DE21 6JN England Tel: + 44 (0) 1332 253400 Fax: + 44 (0) 1332 371061 Email: helpline@jehall.co.uk www.jehall.com Issue: 01.05.2019...
