When connecting the outdoor unit's connector pipe and the EEV KIT pipe, be sure to use a socket (not provided) that meets the necessary specifications. As the size of the EEV KIT pipe and the outdoor unit's connector pipe could vary, check the sizes beforehand and use a socket that meets the necessary specifications.
EEV KIT INSTALLATION WARNING • While welding, always be careful that no refrigerant leaks. • When refrigerant combusts, it creates a toxic gas that is harmful to the body. • Do not conduct welding in an enclosed area. • After welding a pipe, be sure to test for any leakage.
EEV KIT INSTALLATION pipe cutting Be sure to use a copper pipe cutter for the pipe cutting. Copper Incline Roughness 90° pipe cutter Pipe CAUTION • Cut the cutting area in a straight line. Remove any burrs. (When cutting, have the pipe end tilted downward so that any burrs do not get inside of the pipe.)
■ AHU EEV controller (sold separately) WARNING • Please connect one controller with one terminal block of EEV KIT. Failure to do so may result in component damage or fire. (Refer to correct wiring.) • To connect with EEV KIT (PRLK594A0), the AHU EEV controller must be purchased separately.
• Before installation, check the color on the label and connect it to the terminal block. • It may result in malfunction. • Use a ring type terminal (P4) to connect to the terminal block. Close the cover of the EEV KIT terminal box (B).
LEAK TEST AND VACUUM LEAK TEST AND VACUUM Leak test Leak tests are carried out to standards identical with the MULTI-V leak test. Leak tests are carried out by pressurizing nitrogen gas to 3.8MPa (38.7 kgf/cm ). Refer to the following picture for test methods.
