Page 3: Introduction
2. ENCODING AND CONSTRUCTION PPU-LCHX is a pipework package unit for liquid coupled heat exchangers that are used for heat/cold recovery in the air handling units (AHU). PPU ensures proper circulation of thermal medium (usually mixture of glycol and water) throughout the piping circuit, regulates requperation efficiency and prevents coils from freezing. -

Page 10: Periodical Maintenance
If there is a need to perform any mechanical works on the piping circuit (for example to tighten couplings or to clean water filter and etc.) disconnect PPU and AHU from the mains power. It is recommended to carry out PPU-LCHX periodical maintenance at least once a year. If needed register performed works in the maintenance log. - Page 11 DN20-DN32 42-92 DN40-DN65 42-92 UAB KOMFOVENT we reserve the right to make changes without prior notice PPU-LCHX_21-05...
