Connect the hoses, blue charging valve and yellow team the coolant with all valves closed bridge . If the team had a leak and lost much of its coolant , it is advisable to empty the vacuum cicuito and prior to loading. Proceed to vent hoses to prevent air from the bag into the circuit. To do this open the coolant bottle and let gas escape from the yellow hose union with the bridge. And similarly proceed with the blue . Eventually Although a simple check that the tightness. We turn to the bottle to be assured by liquid phase load.
Louisville Cost of Ductless HVAC Systems – Summer Season.
We operate the equipment in cold, we assume that environmental conditions are typical of summer. To load in winter following a similar procedure will be explained later. Measure the condenser temperature gas pipe and observe that the bulb temperature is above the dew marked for this gas, the pressure gauge. We are slowly opening the valve and check blue jumper liquid entering. We let between coolant about four or five seconds and closed, waited a couple of minutes for the gas to diffuse well and measure the temperature again.
Louisville Ductless HVAC – Summer Season.
We will check the temperature gauge has gone up and the thermometer has dropped . We repeated the charge, with patience and care until the thermometer temperature is maintained between 39.2 °F and 44.6 °F above the manometer us . At that time , regardless of the ambient temperatures will optimal charging equipment .
Louisville Ductless Heating and Cooling – Winter Season.
The winter, With The team running in heat, is exactly the same but is varied: We replaced the blue hose for the red hose, and we use the high pressure gauge, temperature is Measured in the liquid line (the opposite to load Howitzer) and finally the temperature of the thermometer is below the pressure gauge. We must make the difference is for gases R -22 or R-410A 5 to 8 degrees, and the R407C, between 10 and 13 degrees (due to slippage typical of this gas mixture).
