TABLE OF CONTENTS
1. General Information
The subject matter of this study is the Operation and Main-
tenance Manual for the typeline of suspended modular air
conditioning and ventilation units type MCKT, manufac-
tured by KLIMOR S. A.
The purpose of the OMM [Operation and Maintenance
Manual] is to familiarise installers and users with the con-
struction, fitting, start-up as well as correct servicing and
operation of the unit. Prior to installing and operating the
unit, you should read through this Operation and Mainte-
nance Manual and follow strictly the guidelines and recom-
mendations contained herein.
The maintenance manual should always be near the unit
and be easily available to servicing personnel.
Non-compliance with the guidelines
and recommendations contained in the
Operation and Maintenance Manual
shall relieve the Manufacturer of war-
ranty-related liability.
2. Technical Data and Use
The MCKT Suspended Modular Air Conditioning and Venti-
lation Unit is designed for air conditioning and ventilation
systems, intake and outlet installations and with heat re-
covery for all types of public and private premises. Owing
to its height it has been designed to operate as a suspend-
ed unit. It operates with the use of outdoor and re-circu-
lated air. The source of power is electrical current; utilities:
heating/chilled water and Freon. The unit is manufactured
in the typeline of three sizes.
In standard version the unit is not designed
to operate in an environment of air tempe-
rature exceeding 45ºC and relative humidi-
ty of more than 60% and in an environment
endangered by the explosion of flamma-
ble gases and fumes that contain organic
solvents or other aggressive substances.
2.1 Functional Systems
Fitted with a set of functional modules, the unit enables
any air processing from the simplest air intake and outlet
to preparing intake air with regard to such parameters as:
• temperature: heating – water or electric heaters, cooling
– water or DX cooling coils
• air cleanness: preliminary and secondary filters
• noise level reduction – silencers
• heat recovery – counter-current cross-flow exchanger
with by-pass, heat pump.

The units may operate to intake, outlet air and in in-
take-outlet systems with heat recovery on a highly ef-
ficient counter-current exchanger with a performance
of up to 92% and on a heat pump. Moreover, they may
be fitted with silencer and secondary filtration sections.
As an option, they may be fitted with a mixing chamber
composed of two supplied air dampers located/assem-
bled on the channels.

2.3 Compact and Modular Units
With regard to the MCKT unit’s fittings, we can distin-
guish between two versions of the unit:
Compact Unit
– is made up of a single module with
a fan and a maximum of two air processing functions
(filtering and heating; filtering and cooling) – all units
in one casing with channel terminals and a shutoff air
dampers.
