Page 3: Safety Precautions
Safety Precautions Please read the following safety precautions carefully. Failure to follow safety precautions could result in death or serious injuries. Important: • Installation of equipment in corrosive, combustive or explosive environment is strictly prohibited. • Do not use Oxygen, Acetylene, poisonous or any other gas that will cause explosion during equipment leak test. Warning: • Installation and maintenance should be performed by qualified personnel who are familiar with the product, local codes and regulations. • The equipment must be installed according to local rules and regulations. • Field-installed wiring must comply with local codes and regulations, and must be carried out by qualified personnel. • Power supply must comply with unit’s name plate specifications. • The unit must be GROUNDED to prevent possible hazards due to insulation failure. -

Page 5: Installation
Installation Location and Clearance • Unit must be installed on a flat concrete base which could withstand the weight of the unit. Vibration isolator should be installed to give a minimal unit vibration. • Do not install unit under explosive, combustive and corrosive environment. • Do not expose unit to direct sunlight. Unit should be installed under shaded or covered area. • Sufficient space must be allocated for water drainage, ventilation and service. Main water supply and return should be located at least 1 meter away from the unit for maintenance. Proper water drainage should be prepared for maintenance purpose. Caution: Every module has pre-set address via DIP switch setting on the PCB. Unit must be placed according to the numbering label on each module. -

The pipe size of the chilled water supply and return are: Cooling / Heating Capacity, kW 120 230 350 465 580 Pipes diameter DN (mm) 100 125 150 170 • Make sure the chilled water supply and return pipe connections to heat exchanger are correct. • Install gate valve, pressure gauge and thermometer both at the chilled water supply and return pipes for ease of service and maintenance work. Pressure gauge and thermometer should be installed at visible and accessible location. • Strainer should be installed at water inlet of every module and before water pump to filter off foreign particles from entering water pump and heat exchanger. • Balancing valve should be installed at every module to ensure every module has same water pressure drop. The temperature difference between water inlet and outlet normally will be 5°C.

Leak Test Testing pressure for water pipe should be greater than 1.25 times the working pressure, and should not be less than 0.6MPa. Piping system is considered leak free if pressure drop is less than 0.02MPa after 5 minutes of pressure test. Water pressure test should not be carried out at ambient temperature lower than 5˚C. Pressure gauge should be well-calibrated with step precision of not less than 1.5; full scale value should be 1.5 to 2 times the biggest tested pressure reading. - Page 9 Wiring Diagram Model: FCA 201 EC/NC (Single / Master) Page 8...

Page 25: Servicing And Maintenance
Service And Maintenance To prolong the lifespan of the chiller and also to reduce unnecessary down time, it is strongly recommended to perform scheduled inspection and maintenance as follows: • Inspect the condenser coils for dirt and debris. Clean condenser coil if necessary. • Inspect all the piping components. Clean strainers and replace if necessary. • Check and tighten all the wiring connection as necessary. • Drain out the water completely if the unit is not operating for a long period. • Perform leak test on refrigerant system if pressure drop occurs. Evaporator The construction of the evaporator does not allow it to be cleaned mechanically. However, chemical cleaning should be adopted, by the following: • Use only chemical additives from authorized dealer. • Use the right amount of chemical according to cleaning direction. Follow exactly the cleaning or neutralizing procedure after cleaning. • It is recommended to engage professional water treatment personnel to perform chemical cleaning. CAUTION: EXCESSIVE TREATMENT AND INAPPROPRIATE CHEMICAL CLEANING OF WATER CAN CAUSE MORE HARM THAN NONE AT ALL. DAMAGE COULD BE DOBE TO OTHER SYSTEM COMPONENTS LIKE PUMP, COOLING TOWER, PIPING AND ETC. -
