38GLP---G / 38GLP---G9 General information IMPORTANT: During the unit installation make first refrigerant connections and then electrical connections. If unit is uninstalled first disconnect electrical cables, then refrigerant connections. WARNING: Disconnect the mains power supply switch before servicing the system or handling any internal parts of the unit. • The manufacturer declines any liability for damage resulting from modifications or errors in the electrical or refrigerant connections.
38GLP---G / 38GLP---G9 Warnings: avoid.... ENGLISH Disconnecting the refrigerant connections after installation: this will cause refrigerant leaks. Connecting the condensate drain pipe to the outdoor unit. Excessive height difference between indoor and outdoor unit (see Table II "Connections"). Excessive distance between indoor and outdoor units. (see Table II "Connections"). Predominant head winds. Unnecessary turns and bends in the connecting pipes.
38GLP---G / 38GLP---G9 Refrigerant connections No moisture. No dust. Charge liquid-no gas. No leak. No mineral oil. Copper tubes during storage. Neat. 1/2” UNF (R-410A) Use tools designed for R-410A higher pressure. Keep inside clean. Dry nitrogen brazing. Min. – 100 kPa (– 755 mmHg) Vacuum. GB - 6 2-stage vacuum pump. Replace oil regularly.
38GLP---G / 38GLP---G9 Refrigerant connections ENGLISH Flaring the ends of the tubing 2 1 The unit can be installed: 햲 on the floor; 햳 on the wall using the bracket kit. Remove protective caps from copper tube ends. Position tube end downward, cut the tube to the requested length and remove the burrs with a reamer. Do not leave system open to atmosphere any longer than minimum required for installation. Oil in the compressor is extremely susceptible to moisture absorption.
