(Pay attention to the tightening torque, see Section 4.1).4.6 Pressure test and filling the coolant circuit● Perform pressure test with nitrogen.– Use nitrogen 4.0 or higher.– Maximum 40 bar.● After leak search is complete, completely drain.● Evacuate the lines (see installation instructions of the heatpump external unit).● Open stop valve on exterior unit completely until the stop.Tighten loosely.● Reassemble valve caps.A DAIKIN EWQB DAIKINEKHHPC Gas lineD Liquid lineE Oil trap arcH height to 1st oil trap (max. 10 m)H O Height difference between heat pump exterior unit and heat pumpinterior unit.Fig. 4-7 Oil trap arc coolant lineHEBCDHoARISK OF ENVIRONMENTALDAMAGE!Important information regarding the coolantused.The complete heat pump system contains re-frigerant with fluorinated greenhouse gaseswhich damage the environment if released.Coolant type: R410AGWP* value: 2087,5* GWP = Global Warming Potential● Work on fixed cooling systems (heat pumps)and air-conditioning systems can only beperformed by persons who hold a certificateof competence for the European Region, inaccordance with the F-Gas Regulation (Ec)No. 303/2008.● Fill in the total coolant filling quantity on thesupplied lable on the heat pump exterior unit(for information consult the installationinstructions for the heat pump exterior unit).● Never allow coolant to be released into theatmosphere - always suction it off and recycleusing a suitable recycling device.No additional coolant is required for the basic filling.This is independent of the line length between the in-ternal unit and external unit.
