Installation Precautions

1. Before starting, verify the power supply voltage meets the requirements of machine parameters.
2. To ensure safety, keep the chiller away from aquatic animals (i.e. fisheries, aquariums, farms, etc.) or other equipment (such as lasers) to avoid possible moisture leakage.
3. Keep the chiller out of reach of children to avoid accidental injury.
4. Install the chiller in a well-ventilated, dry, covered area. Maintain a minimum space of 12 inches around the chiller and keep the exhaust area clear within 5 feet.
5. To prevent the water inlet from clogging, we recommend installing an in-line filter ahead of the chiller inlet. Regularly check the working operation of the pump to avoid waterless operation.
6. Use Schedule 40 or 80 PVC or similar pipe with adequate wall thickness. This will prevent warping around inlet and water obstruction that could result in failure of chiller cooling capacity.
7. Double check the power and cable connections for abnormal behavior or foul smell of electrical components, replace or repair prior to operation.
8. The water tank in this chiller has a maximum water pressure of 30psi (0.2MPS – 2KGF / CM2). Excessive water pressure can cause the water tank to rupture. The water pipe and pump should be matched reasonably.

**If the chiller has not been utilized for a long time, turn off power supply. Ensure the north region inside the barrel of pure titanium evaporator through the bottom of pump is dry to prevent cracking.

Troubleshooting

1. If the ambient temperature or water temperature is too high this can lead to an increase in system pressure. Increase in pressure may cause compressor to cut out to protect the chiller. If this happens, ensure appropriate ventilation and/or cooling, then chiller will restart.

2.  After prolonged normal use (2-3 years), refrigeration capacity may be significantly reduced. Please contact a qualified HVAC technician for maintenance to recharge refrigerant.

3. If the display board is dim, or the machine does not operate correctly, check to ensure the power plug is not loose and check fuse. For insurance, replace fuse.

4. If the digital display shows and error between the actual temperature and display temperature, perform the following procedure to rectify.
   a) Press the “SET” button for 10 seconds until the display reads “F1”.
   Press SET” again to correct temperature function “F2” (F2 is plus or minus 59°F degrees)
   b) Press the “+” key (to increase ) or “-” (to reduce ) to confirm to eliminate error of digital display.
   Numbers indicate error value (F2=actual temperature − display temperature)
   c) Stop any operation, wait after 10 seconds for digital display to show actual temperature.

5. If display still displays incorrect value after procedure, contact dealer for professional maintenance. Do not perform maintenance without professional analysis.

Common Maintenance Schedule

1. With normal prolonged use (2-3 years) the chiller capacity may diminish or refrigeration decreases, check to ensure that refrigerant level is adequate. If refrigerant is low contact an HVAC professional to recharge refrigerant (R410a) to appropriate level.
2. With normal prolonged use, air or water temperature might become too high due to restriction of air flow. If temperature exceeds normal operating temperature, power off the chiller, clean dust accumulation on compressor to increase ventilation and heat dissipation to restore normal operation.

INSTRUCTIONS FOR SAFE OPERATION:

1. All external components must be kept dry.
2. Ensure the chiller’s power supply is correctly grounded.
3. Installation surface must be level and firm.
4. If the chiller is upside down or on it’s side, it may damage internal components and prevent the unit from running properly. Unit must be installed level and upright and remain level for at least 30 minutes prior to start up.
5. Chiller must be installed on an upright and level surface for at least 4 hours after delivery before start up to allow compressor fluid to normalize.

Cleaning Instructions

For safe, efficient operation and long service life, it is essential to regularly clean the chiller condenser and all hoses, connections and other components in the system. Thorough cleaning is recommended every 3-6 months, including:

1. Remove dust from the condenser with a brush or compressed air.
2. Rinse collected debris from external reservoir pump, all inlet and outlet connections, hoses, etc., with clear, luke warm water. Soap, detergent or bleach is NOT recommended because any remaining residues can contaminate the nutrient solution. The chiller housing, digital control panel, power switch and other external surfaces must be cleaned with a soft, dry cloth. NEVER immerse the chiller in water or spray it down with a hose!

How to clean the water chiller condenser?
The following are two options.

1. If the chiller is installed in a relatively clean place, you can remove the dust from the condenser directly with a brush or compressed air, typically every six – twelve months. No need to remove chiller case.
2. If the chiller is installed in a dusty area, it is recommended to clean the condenser once every 3 to 6 months.

Cleaning Instructions

1.  Loosen screw on cover, turning counterclockwise.
2. Loosen screws on the back side of condenser and remove.
3. Remove dust with a brush, compressed air or wipe clean with a damp cloth.
