d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is toensure that only the original composition of R410A is being delivered into the system. The liquid compositioncan be different from the vapor composition.Dip-pipeInvert cylinderwithout dip-pipeLiquidwithdrawalf) Normally, the R410A cylinder or can is being equipped with a dip pipe for liquid withdrawal. However, if thedip pipe is not available, invert the cylinder or can so as to withdraw liquid from the valve at the bottom.32
Electrical ConnectionsWiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICALCODES for field wiring rules. Be sure that installation comply with such rules and regulations.General PrecautionsEnsure that the rated voltage of the unit corresponds to the name plate before carrying out proper wiringaccording to the wiring diagram.Provide a power outlet to be used exclusively for each unit. A power supply disconnect and a circuit breaker forover current protection should be provided in the exclusive line.All wiring must be firmly connected.All wiring must not touch the refrigerant piping, compressor or any moving parts of fan motors.Operational CheckAfter all wiring is completed and the system is charged with refrigerant, make sure that unit is operating properly.Check that :• Condenser fan is running, with warm air blowing off the condensing unit.• Evaporator blowers are running and discharging cool air.• The micro-computer system incorporate a 3-minute delay in the circuitry. Thus, it requires about 3 minutesupon cut off before the outdoor condensing unit can start up.• To check if there is any miswiring, turn on one unit at a time.• After running for 10-15 minutes. Check if the suction (low side) pressure is within normal operating range.33
