9.5 GENERAL OPERATION AND MAINTENANCE OF THE UNIT
Anyone conducting maintenance on air handling units must be familiar with the maintenance
instructions and adhere to the recommendations specified therein. These instructions are an
additional source of information and anticipate knowledge of the rules of assembly and
operation for CPV class air handling units from MANDÍK, a.s. and adherence to all the
requirements specified therein. The manufacturer assumes no liability for any damage
caused by the failure to adhere to such rules of assembly and operation and these
instructions.
Air handling units are used to condition and convey air and require regular cleaning and
maintenance. Based on the scope and intended use of HVAC equipment, and the components,
composition and the features of the air handler itself, we recommend operators draft local
operating and maintenance regulations that fully comply with the requirements of the rules of
assembly and operation and instructions for the maintenance of CPV class air handling units
from MANDÍK, a.s.
Any maintenance intervals specified below are indicative only and valid for air containing
normal quantities of individual pollutants. These intervals may be extended or shortened,
depending on local operating conditions, the nature of the equipment, and the pollutants
contained in the conveyed air. These intervals do not relieve the operator of its obligation to
ensure the flawless and safe operation of the air handler on a day-to-day basis.
All elements which, by their nature, are intended to be extended, opened or easily dismantled
must be positioned so that the interior of the unit can be cleaned as thoroughly as possible.
Use a vacuum to remove coarse dirt and debris, or use a damp rag if necessary. Use a neutral
cleaning product to remove any grease and then again wipe down the surface with a damp rag.
Properly treat and repair any damage to painted surfaces or surface corrosion with a suitable
coating. Moving parts (hinges, door handles, etc.) must be lubricated with a lubricating spray as
needed. All inspection doors must be properly installed and checked to ensure they open
freely. Per the conditions for placement of the unit, a door may need to be levelled by adjusting
play on the fasteners on the handles and hinges. Check for proper mating of doors to the gasket
surfaces. Door gaskets must be inspected and then repaired or replaced if they leak.
