Cooling coils are used for air cooling in ventilation systems.
The coil consists of copper tubes and aluminium ns. The casing is made of galvanized sheet steel.
RWC-type coolers use coolant - cold water. RFC-type coolers use the R410A freon.
Easy to mount.
Suitable for operation indoor environment.
The purpose of the unit is: cooling of clean air. The unit is used in clean air ventilation and conditioning systems.
Units are packed in the factory to complay needs of normal transportation handling. Use suitable lifting and moving equipment when handling units in
order to prevent damages and injuries. Do not use cables, terminal boxes, and inlet-exhaust anges for lifting and moving units. Avoid hits and shock
loads. Units should be stored in dry rooms where relative humidity max. 70% (at +20oC), ambient temperature is within the range of +5oC to +40oC.
Units should be protected from dust, dirt and water.
Avoid long term storaging. Longer than 1 year is not recommended.
- Do not use the unit for purposes other than its’ intended use.
- Do not disassemble or modify the unit in any way. Doing so may lead to mechanical failure or injury.
- Use special clothing and be careful while performing maintenance, and repair jobs - edges of the components’ casings may be sharp and cutting.
- Do not place or operate unit on unsteady surfaces and mounting frames.
- Mount the unit rmly to ensure safe operating.
- Never use this unit in any explosive or aggressive elements containing environment.
- Installing should only be performed by qualied and trained sta󰀨.
- Coils are designed for mounting in horizontal position.
- Water connection process should be processed using mounting scheme (see the scheme S1).
S1:
a - water ow out;
b - air ow;
c - water ow in.
When cooler is already mounted the draining system has to be connected. In order to do that siphon must be screwed to the cooler draining exhaust.
The draining system should be lled up with at least 0,5 l of water (siphon must be always lled with water).
Check if water reaches sewerage system.
Installed heaters must be 0-3o slope angle (g. S2).

Maintenance shall be performed only by experienced and trained qualied personnel.
During maintenance, it is recommended to check the proper operation of the product at regular intervals.
During the periodic inspection, make sure that:
1. There is no mechanical damage on the casing.
2. There is no coolant leak.
3. The system has proper pressure (it is especially important for RFC type freon coolers).
4. There is no air in the system of the RWC type water cooler.
5. There is proper uninterrupted water circulation in the system of the RWCtype water cooler.
6. The air ducts are connected tightly, i.e. there are no cracks, tears, or other mechanical damage that may cause leakage in the system.
Cleaning
If cooler is soiled it should be cleaned.
1. Detach unit from ventilation and water supply systems.
2. Coil can be cleaned using tepid water and alkaline micture which does not generate corrosion on aliuminium;

unit. The equipment is shipped in good working order and condition to the direct client. The unit is warrantied for the period of two years from the
invoice date.
2. If equipment is found to have been damaged during transportation, a claim should be made against carrier, as we assume no responsibility for such
damage.
3. This warranty does not apply:
3.1. when transportation, storage, installation and maintenance instructions of the unit are violated;
3.2. when the equipment is improperly maintained, mounted - inadequate maintenance;
3.3. when the equipment without our knowledge and permission has been upgraded or unskilled repairs were made;
3.4. when the unit was used not for its original purpose.
4. This warranty does not apply at these malfunction cases:
4.1. mechanical damage;
4.2. damage caused by entering outside objects, materials, liquids;
4.3. damage caused by natural disaster, accident (voltage change in the electricity network, lightning, etc..).
5. The company assumes no liability for its products either directly or indirectly damage, if the damage is caused by failure to comply with installation
and mounting regulations, deliberate or careless users or third-party behavior.
These conditions are readily discernable when the equipment is returned to our factory for inspection.
If the direct client determines that equipment is found to be faulty, or a breakdown occurred, he should inform the manufacturer within ve working days
and deliver the equipment to manufacturer. Delivery costs should be covered by customer.
