Installation instruction Note: 1. When connecting the pipe and the outdoor, please pay attention to the outdoor pipe dimension. 2. When adjusting the diameter among pipes and among the units, please must execute at the branch pipe side. 3. When welding with hard solder, please must blow nitrogen. If not, a number of oxide will be produced and cause heavy damage.Besides,to prevent water and dust into the pipe, please make the brim as outer roll.

Installation instruction Because the unit is with refrigerant R410A, the below issues should be paid attention: • To prevent the different oil into the pipe, please use the special tool for R410A, especially for gauge manifold and charging hose. • To prevent the compressor oil into the refrigerant cycle, please use the anti-counter-flow adapter. (8) Check vale operation Open/close method: •...
Electric wiring and the application WARNING Inspect • Switch off the main power switch of the indoor • To ensure that the electrical equipment used on the installation and outdoor machine for more than 1 minutes site (main power switch, circuit breaker, wire, conduit and wiring before the wiring or regular inspection.

Trial operation and the performance Confirm the type of outdoor machine and the number of inside machine • After installation, please confirm that the outdoor computer board BM1_1 is in the 0 state, and then to the unit power, observe the digital display. If the number of the indoor machine and the outdoor machine type, the power supply voltage is correct, then the BM1_1 dial to 1 of the state, if it is not correct, please check the dial machine communication code and models, do not force the BM1_1 dial to 1 of the state, it may cause failure of the system.

Trial operation and the performance Trial operation • Before trial operation: Before being electrified, measure the resistor between power terminal block (live wire and neutral wire) and the earthed point with a multimeter, and check if it is over 1MΩ. If not, the unit can not operate. To protect compressor, electrify the outdoor unit for at least 12 hours before the unit runs.If the crankcase heater is not electrified for 6 hours, the compressor will not work.
Move and scrap the air conditioning • When moving, to disassemble and re-install the air conditioning, please contact your dealer for technical support. • In the composition material of air conditioning, the content of lead, mercury, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers are not more than 0.1% (mass fraction) and cadmium is not more than 0.01% (mass fraction).
