Safety Precautions; Maintenance - Salda AVS 125 Mounting And Installation Instruction

6. SAFETY PRECAUTIONS

• 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 firmly to ensure safe operating.
• Never use this unit in any explosive or aggressive elements containing environment.
7. MOUNTING
• Installation works shall be performed only by trained and qualified personnel.
• Remove safety cover before starting mounting procedures (pic. S1).
• Coils can be mounted only horizontally.
• The unit shall be installed firmly and tightly to ensure safe operation.
• The unit shall be mounted on a flat surface so that the product is not leaning.
• Installation shall be performed in such manner that the weight of the air duct system and its components would not overload the ventilation unit.
• Enough space must be left during installation for opening of the maintenance door of the unit.
• When connecting water heater, the weight of the water pipes and thermal tensions should not be transferred on the heater branches.
• When mounting threaded connections of supply pipes and heaters, use two spanners (pic. S3).
• Pipes are connected to the heater in such way that they could be easily disassembled and the heater could be removed from the unit casing
when performing service or repair works.
• Pipes with supply and return heat carriers must be connected in such way that the heater would work in the opposite direction for the air flow. If
the heater works using the same directions, the mean temperature difference decreases which affects the heater efficiency (pic. S2).
Max. operating pressure: 1,0 MPa;
Max. operating temp.: 100 °C.

8. MAINTENANCE

Checking:
• Check if connections between the unit and ducts are hermetical.
• Check performance of thermal circulation. Temporary increase water temperature for this.
• Check tightness of water supply system.
Cleaning:
• Disconnect and remove heater.
• If heater is soiled - use vacuum cleaner or airflow blast.
• In case of heavy choking - clean with warm water and mild detergent solution.
• Check tightness of tubes of disconnected and removed heater with high-pressure air.
