Grunbaum ac7000 ошибка w20a

Что мне не нравится в китайских установках? Их универсальность! И немного непонятная несбалансированность!

В итальянских или немецких установках вы почти не встретите большого баллона на 22 л и «дохлую» вакуумную помпу 100 л/мин. Обычно, если баллон на 20 л, то и помпа на 150-180 л/мин. Это объяснимо. Не имеет смысла ставить в установку баллон на 20+ литров и слабый насос. И наоборот.

Второй момент — универсальность. Китайцы пишут — легковые, ком транс, автобусы. Смешно, но реально эта установка может откачать холодильник автобуса в 4 кг хладона. Вопрос как долго она сможет это делать? Тот же 690 робинайр не может откачать столько — срабатывает тепловая защита, которой в грюнбауме просто нет!

Ну и я не верю в то, что китайские инженеры совершили открытие на этом фронте. Я видел как эти установки сделаны внутри — минимализм.

  4. After about 5 seconds , The oil draining process would be finished. RECOVERY FINISHED! PRESS OK TO CONFIRM! 5. Press key to stop the alarm buzzer, then the recovery process finished! Note: After first phase of recovery, you need to spend some minutes, just waiting for more refrigerant evaporate into gas, if the pressure inside the A/C raised, the equipment will go on the recovery process, or it will go to next step.

  7.5 Purge The purge is designed to discharge the mixed non-condensable gases in the inner tank. It is harmful for the A/C station when the tank pressure is exceeded. It must release some pressure till to normal level. You no need to do this operation every time when you service a car, but need to check the tank pressure through the gauge in the morning before using it.

• Page 22: Auto

  7.6 AUTO The automatic operation is including recovery, oil drain, vacuum, oil injection, and recharging, all steps are in one press. Before operation, you must confirm that the new PAG oil is enough, or it has risk that the air would be sucked into the vehicle A/C system.

• Page 23: Pressure Up

  7.7 PRESSURE UP When the A/C system pressure is lower than desired, only due to shortage of refrigerant inside the A/C system, In this case, you no need redo all recovery/recycling/recharging process, by this function you could add some gas into the system and let the pressure rise to normal.

• Page 24: Vacuum Test

  7.9 VACUUM TEST After a vacuum operation,if the A/C system can hold the vacuum state, that means the system is OK, if it lost some vacuum, there should be existing the leakage in somewhere. the operation is divided into two steps, first is vacuum, second is vacuum test.
