Ensure the supply circuit is closed (no pressure) before connecting the suction lines. Ensure the flame nozzle is not aimed at the equipment, when welding. Pressure test Ts'=cold room air inlet temperature. Te=evaporating temperature. It is related to the refrigerant pressure on the unit cooler outlet. Trs=refrigerant superheat temperature, on suction line near thermostatic valve bulb. (Trs-Te)=superheat (Trs-Te) ≤ 0.7 x (Ts'-Te) Keep the superheat as low as possible to obtain maximum unit cooler performance. The thermostatic valve fitted must be correctly sized for the installation conditions and adjusted for correct system operation. 31231499EN-09 LU-VE Exchangers is a trademark registered and owned by LU-VE Group.

• Electrical options When in doubt always contact your local supplier or LU-VE Exchangers representative for assistance. Ensure complete electrical isolation before performing any wiring. In accordance with the current legislation, install a single pole terminal in a visible position between the unit and the power supply. Opening between terminals 3 mm at min. Connect terminals by following the wiring diagrams on the cover. For systems using electrical/hot-gas defrost, a heaters defrost termination thermostat should be used, having a range of 10 °C to 20 °C with a sensor attached to the top return bends of the coil block or buried in the top of the coil block fins. 31231499EN-09 LU-VE Exchangers is a trademark registered and owned by LU-VE Group.
