Page 4: Safety Considerations
The three types of cautionary items above are very important for safety: be sure to observe all of them as they relate to installation, use, maintenance, and repair. Furthermore, TLV accepts no responsibility for any accidents or damage occurring as a result of failure to observe these precautions. - Page 5 Precautions for the Entire Unit WARNING For applications such as handwashing in which hot water directly touches hands, when using the one-pass method, make sure to install a thermostatic mixing value at the outlet. Failure to observe this precaution may result in burns, as water at a temperature higher than the set temperature may flow due to load fluctuations.
- Page 6 When all the piping work is completed based on the system CAUTION flow diagram, inspect once again that all the piping connections and internal G threaded connectors are properly tightened, gaskets have been installed and that no parts or connections are loose. Failure to do so may result in burns or other injury from discharge of fluids.
- Page 7 Unit components such as steam piping may become hot CAUTION during operation. Do not touch components with bare hands. In the event of an earthquake, close the main steam supply valve and shut down the unit promptly. If the tube inside the heat exchanger of this unit is damaged due to an earthquake, a large amount of steam will enter the hot water piping, which may result in burns.

Page 15: Precautions Before Unit And Piping Installation
3. When installing the unit in a high place, make sure to install the unit at a location where maintenance work etc. can be carried out, and where handrails etc. are installed to prevent falling. If work cannot be performed, TLV may refuse after-sales service. - Page 16 6. Precautions before connecting to piping Make sure to flush the steam piping and water supply piping before connecting the unit. The purpose of flushing the piping is different from the initial blowdown, which is carried out to discharge condensate before operation. Flushing is performed to remove the residual sealing material, metal chips, sand or scale in the piping.

Page 17: Piping Work
Piping Work For applications such as handwashing in which hot water directly touches hands, when using the one-pass method, make sure to install a WARNING thermostatic mixing value at the outlet. Failure to observe this precaution may result in burns, as water at a temperature higher than the set temperature may flow due to load fluctuations. - Page 18 e) When installing the peripheral piping, be sure to support the surroundings so that the load and stress of the piping and other equipment are not applied to the unit. f) For the water supply system and components to be connected to the unit, follow the instructions provided by the organization that designed and installed the system.
- Page 19 (1) Steam Inlet Piping a) Install a pressure gauge at the steam inlet. Supply steam pressure range: 0.2 to 0.7 MPaG. b) Make sure to install piping support(s) for the steam inlet piping. c) Install a valve for emergency shutoff and maintenance at the steam inlet.
- Page 20 Make sure to install the steam trap provided as as a standard accessory. (When using another steam trap, contact TLV.) b) Make sure that the piping installed between the unit and the steam trap is as short as possible, with as...

Page 22: Commissioning
Commissioning Hot water may flow out when water is initially supplied after restarting operation. In addition, pay extra attention when changing the set CAUTION temperature or when the flow rate of hot water changes significantly and check the temperature before use. To prevent burns, do not touch hot water for at least five seconds after restarting operation. - Page 23 Initial blowdown Before commissioning, make sure to perform flashing and blowdown. If blowdown has not been adequately performed, TLV cannot guarantee against damage or performance loss of valves and the unit due to scale. Check to make sure that steam is supplied just before the valve at the steam inlet and that the pressure gauge reading is 0.2 to 0.7 MPaG.

Page 25: Operation
Operation Hot water may flow out when water is initially supplied after restarting operation. In addition, pay extra attention when changing the set CAUTION temperature or when the flow rate of hot water changes significantly and check the temperature before use. To prevent burns, do not touch hot water for at least five seconds after restarting operation. - Page 26 Initial blowdown of the steam piping and the water piping just before the unit should be carried out when operating the unit after the unit is shut down for a long period of time (more than a day). Initial blowdown means the elimination of condensate remained in the steam piping and the elimination of rusty water in the water piping.
- Page 27 Shutdown If the product is not used for a long period of time (one day or more) after the operation, stop steam and water supply to the unit and then shut down the unit. Before finishing operation, make sure that hot water is not being used at the intended location for use.
