Procedures
2Установка и подключение аккумуляторной системы installation
⚠ При зарядке батарей выделяются взрывоопасные газы – обеспечьте вентиляцию, вдали от искр и открытого огня.
⚠ Перед подключением батарей переключатель Run/Off/Auto на панели управления должен находиться в положении Off (ВЫКЛ).
⚠ Не устанавливайте кислотные батареи в одном помещении с никель-кадмиевыми.
Tools: Торцевой гаечный ключ
- Установите батареи в чистое, хорошо освещенное и вентилируемое место с легким доступом для обслуживания.
- Подключайте землю ПОСЛЕДНЕЙ, а при извлечении батареи отключайте ее ПЕРВОЙ.
- Вначале подключайте ПЛЮСОВОЙ кабель генератора, затем минусовой; соблюдайте полярность.
- Тщательно затяните гайки межъячеечных соединений и смажьте контакты вазелиновым маслом.
- Для 24 В соедините две или четыре 12-вольтовые батареи последовательно.
Методика подготовки хладагента maintenance
⚠ Перед снятием крышки радиатора дайте системе остыть и стравите давление.
- Добавьте требуемое количество воды в смесительный резервуар и растворите в ней требуемое количество DCA.
- Добавьте требуемое количество антифриза и тщательно перемешайте.
- Залейте хладагент в систему охлаждения и надежно заверните крышку радиатора.
