Page 3: Safety Precautions
Generally, system air conditioners should not be relocated after installation. But when it has to be relocated for ❇ ❇ ’ inevitable reasons, please contact Samsung s qualified dealers for system air conditioners. WARNING • Hazards or unsafe practices that may result in severe personal injury or death. - Page 4 Safety precautions Check the following before installation and service work. Before welding, remove dangerous and inflammable things that may cause an explosion and fire around the work. Before welding, remove the refrigerant from inside the pipe or the product. If you perform welding while refrigerant is in the pipe, it may increase the pressure of the refrigerant and cause the pipe to burst.
- Page 5 CAUTION SIGNS Do not install the drain pipe directly to the bottom part of the outdoor unit and built a proper drainage so that water drains out smoothly. If not, pipe may freeze or bursts during winter time and cause damage to the product or water leakage. When the draining work is not done properly, water leak may occur and cause property damage.
