Notice that the liquid in question cannot be used with water and special liquids such as printing liquids and acidic liquids. For other special liquids (ceramic etc.), contact Teral Inc. Note2 When the dynamic viscosity of liquids used becomes higher than that in the table below, the useful life of the motor may become shorter, leading to a burnout. -
Page 10: Nameplate Entries
Nameplate entries The specifications of the pump are shown on the nameplate. When you receive the pump, check the nameplate to verify that the product is exactly what you ordered. Be sure to confirm the model, motor output, frequency and voltage. If any part of the product should be different from what you ordered, contact the vendor from which you purchased the product. -

3. Transportation, conveyance, storage and installation Precautions for transportation, moving and storing the pump (1) Do not unpack the container unnecessarily. If you unpack the container unnecessarily, securely pack again in such a manner that the product body does not jump out of it and fall down during transportation, conveyance or storage. (2) When you transport, move, or store the pump, ensure that the pump is located in a well-ventilated place with minimum exposure to dust and moisture in an environment at an ambient temperature of -25 to 55 degrees Celsius and humidity of lower than 85%RH. -
Page 15: Precautions For Installation
Caution Do not allow the pump to operate with a frequency beyond 60 Hz. Doing so may overload the motor, causing it to burn out. Precautions for installation Warning Before rotating the pump shaft by hand to check it, be sure to turn off the main power. - Page 16 (10) When the liquid leaks from the product, install it in a place where it is not subjected to secondary damage. (11) If the system could be exposed to the freezing temperature in winter, be sure to apply antifreeze measures such as heat insulation and heater installation to the pump, valves, piping, etc.

Page 17: Precautions For Piping Work
Precautions for piping work (1) The pipes should be as short and straight as possible (with minimal joints and valves). Use pipes whose bore size is equal to or larger than that of the pump. Piping which is thin and has many bends may decrease the delivery volume. - Page 18 Danger Securely connect the terminals of the power cable. Loose terminals may cause an open phase fault, which causes the motor to burn out. (1) For the size of the power cable, refer to the following: Minimum size of the cable Type (200-volt class) All types...
- Page 19 • Ensure that the minimum frequency is set to 20 Hz. (Contact us for operation at 20 Hz or below.) • Contact to the nearest Teral office when using a 400V class model. Protective measures may be required against the inverter surge.

4. Operation Check items before test operation 4.1.1 Check items related to the electrical system (1) Check that the fan is correctly wired. (2) Check that the terminals are securely connected. (3) Check that the fan is securely grounded. (4) Check that the setup value of the overload protection device is consistent with the rated current value of the motor. -

(5) Open the air vent valve to release air. After the air release, close the air vent valve. If the air vent valve is not installed, open the valve of discharge pipe to release the air. (6) If you run the pump while changing the speed with the inverter, check the following points through trial runs without fail. - Page 22 Caution Do not check the rotational direction by the idling of the pump. Running the pump dry even for a short time may cause breakage of the sliding parts (e.g. bearings) in the pump, leakage or unusual noise. Caution Avoid reverse rotation because it may cause failures. Caution Do not run the pump dry, and do not allow a large amount of foreign matter in the pump.
- Page 23 (7) If the liquid level is lowered, the pump takes air in, thus decreasing the delivery volume and disabling pumping-up. The liquid level should be above the lowest liquid level indicated in the outline drawing. However, this liquid level changes depending on dynamic viscosity and the liquid level condition.
- Page 24 (14) Stop the pump. Caution Keep the cocks of the pressure gauges and compound gauge closed except during measurement. Otherwise, they come to fail with ease. Caution Do not run the pump beyond the allowable current value, or the motor may burn out.
