OpenNo gas leakage?5.Detach the charge hose6. from the service port, open 2-way valve and 3-way. Turnthe valve rod anticlockwiseuntil hitting lightly.In case of gas leakage, tighten parts of pipe connection. Ifleakage stops, then proceed 6. stepsIf it does not stop gas leakage, discharge whole refrigerants from the serviceport. After aring work again and vacuumize, ll up prescribedrefrigerant from the gas cylinder.Anti countercurrent jointGaugemanifold(for R410A)2-way valve Liquid Side3-way valve Gas SideVacuum pump(for R410A)Tube(for R410A)Close2-way valve3-way valveOpen 90O2-way valve3-way valve2-way valve3-way valveValve rod capValve rod capService port capTo prevent the gas leakage, turn the service port’s cap, the valve rod’s cap for 2-wayvalve and 3-way’s a little more than the point where the torque increases suddenly.After attaching the each caps, check the gas leakage around the caps.7.8.Step 1.

(Over I0A)In the case of installing an air conditioner in a moist place, please install an ea-For installation in other places, use a circuit breaker as far as possible.Pipe cutting is carried out with a pipe cutter and burs must be removed.After inserting the are nut, aring work is carried out.If the refrigerant of the air conditioner leaks, it is necessary to discharge all therefrigerant. Vacuumize rst, thencharge the liquid refrigerant into air conditio-ner according to the amount marked on the name plate.Please do not let other cooling medium, except speci ed one (R410A), or airenter into the cooling circulation system. Otherwise, there will be abnormalhigh pressure in the system to make it crack and lead to personal injuries.
