The product can be used for small scale refrigeration and heating, aquaculture and aquarium Specification: Item Type: Electronic water chiller Material: ABS+metal Purpose: Plumbing equipment Model: STC-200 Model STC-200 35L Rated voltage DC12V Power 100W Circulating water pump flow 1-3L/min Suitable range Water pump vertical lifting height of three meters below Cooling water ≤35L Suitable water pipe Inside diameter eight millimeter Product size(approx.) 115 x 110 x 190mm / 4.5 x 4.3 x 7.5in Net weight 1.80 kg / 4 lb(approx.) The attachment Two meters of a water pipe, two pipe buckle, a water pump, a power adapter, a power line Water Pipe Connection Operation Procedure: The 2Meter divided into two pipes（length can be determined according to their own use）, respectively set tube buckles on the pipe, connecting the inlet and outlet pipe clamp the buckle fixed tightly connected to the pump and the power supply can be used directly. 1. Switch on the power, the water began to circulate, and see if there is any leakage. Installation and Use: A. Install the connection as shown in figure. B. Machine and the surrounding space to maintain a distance of more than 20cm, in order to facilitate the flow of heat. C. Transportation, installation, maintenance, please handle with care. Temperature Control Setting Method: “SET” light into set state, “Work” light water cooler to enter the working state. “SET” Set key, “ENTER” Confirm key, “+” Heating key, “-” Cool key Short press "SET" key (set down the temperature), press the "+" or "-" key, to the appropriate temperature. (set after the "ENTER" key or 10 seconds after the automatic return to the current temperature) Detailed Function Table: 1. The normal display state, long press "S" button, display P0, press "S" button, to select the P0-P5（each time you press the "S" button, the display shows the cycle increments from PO-P5）, press the "E" button to confirm, and then press “▲”or “▼” button to set the thermostat function. 2. As shown in table two.（after setting, press "S" key or 10 seconds to return the current temperature automatically） Symbol Significance Degrees Celsius Degrees Fahrenheit Factory Default P0 Refrigeration;heating;cooling mode C/H/CH C/H/CH C P1 Return temperature 0.1~15 0.1~27 2 P2 Correction temperature -7~7 -13~13 0 P3 Time delay (min) 0-10 0-10 3 P4 High temperature alarm temperature -50~110 -58~230 110 P5 Temperature model (degrees Celsius and Fahrenheit) CCCC/FFFF CCCC/FFFF CCCC Sensor fault display E1, close all outputs 1. This product is shown in the cooling water cooling water temperature is 28 ℃, no high power lights and submersible pumps to the water under the premise of the water temperature can be reduced to 25 ℃ or so, the higher the water temperature before cooling, the less the amount of cooling water applied. Cold and warm type cold water machine hot water quantity in the process of making hot water and same as the refrigerating capacity of the refrigerating system. 2. The upper temperature limit of this product is 40 ℃, the lower limit temperature of 10 ℃. Danger: Warning: Attention: Operation not in accordance with the specification may be dangerous. If there is a power line or other fault please find professionals to deal with. Such as illegal operation may cause damage to the product. Cleaning and Maintenance: .
