The casing ñàï only üå removed with à tool. The electrical connections cannot üå touched. The casing is sealed so that water cannot penetrate into the valve when built-in during the wate. ã test of the ãefrigeratoã Functional Tests Flow Rate and Leakage The measurementakes place Üó means of rota.meter at à room temperature of Ñ with compressed air with à pressure ratio of 4/1 Üàã. The valve is operated in the mounting positlon and the media flow is measured. Rolomelet Flow Rate: Leakage: > 1000 I/h (compressedair ð=çüàr) < 5 Vh «0,13 Vh with compressed air ð=3üàã) 6.2 Switching-Function in the Refrigerant-cycle (ÊÌ) The valve is soldeãåd into the complete ãåfrigeãànt circuit. The valve is checked at àn ambientempeãatuãe of 500 Ñ. With à refrigerant-temperature of 600 Ñ, the valve must work in the voltage range of VAC (2ÇÎV version) îã from VAC (10Q-120V version).

With à pressure ratio of 9/1 bar for coolant R600a and 16/1 bar for coolant R1 Ç4à the va/ve must çtill work perfectly with à minimum voltage of 175 VAC (2ÇÎV version) or 85 VAC ( V version) 6.4 Leakage Ò est The valve is connected to the leakage test device. The testing device geneãates à vacuum in the valve. À helium-atmosphere is generated around the valve. If leakage OCCUfs, helium is sucked irto the valve and measured Üó the testing device. The sensitivity of the measuring instrurnent must te set in such à way that approximately 0.5 g/a (Isobutane) ñàï üå measured. This value must not t å exceeded throughouthe duration of the test. 7. Heating of the Coil With the normal pulsed activation of the vatve, heating of the coil ñàï üå neglected. In the event t If àn electrical defect, the solenoid ñàï Üå exposed to the mains voltage îã rectified mains voltage. Th~ voltage is switched îï at the solenoid at àn ambient temperature of Ñ until the steady s~ate condition is achieved.

The fixing point for bending is 50 mm from the soldered joint. The extemal seaing must still Üå guaranteed. 8.4 Securing the Ñàð The cables àãå correctly inserted and the ñàð is locked. Using à force of 50 N attempts àãå made to pull the ñàûå out of the casing. - parallel to the initial position of the ñàûå - perpendicular to the initial position of the ñàûå.
