Page 31: Operation Procedure
Operation Procedure Start-up When operating the unit after a prolonged period of no operation, initial blowdown should be conducted on the steam and water piping preceding the unit. Initial blowdown refers to the removal of residual condensate from steam piping and rusty water from water piping. - Page 32 (Factory setting: 5 seconds). If the flow does not stabilize within 5 seconds and the unit repeatedly starts and stops operation, the alarm delay time must be changed. (Contact TLV for details of how to change the alarm delay time).
- Page 33 (6) Adjusting the set temperature Do not change the temperature settings without contacting the user when washing hands, using a shower or cleaning. Failure to do so CAUTION may result in burns to the user. Touch the "Set Temperature Adjustment" button on the touch panel, and using the keyboard panel, input the desired temperature.
- Page 34 Shutdown When finishing operation, the operation should be stopped in accordance with the proper steps. Incorrect operation of the unit CAUTION during use for hand washing, showering, or cleaning, etc., may result in burns due to malfunction, which causes the temperature of the water to rise above the set temperature.

Page 35: Prevention Of Damage Due To Freezing
Prevention of Damage due to Freezing When draining water from the unit, make sure to wait until the unit has cooled down. If carrying out work after hot water use, there is a CAUTION risk of burns, as the components and the water inside the unit are hot. Make sure measures are taken to prevent freezing of the unit’s steam piping system in cold climates. -
Page 36: Maintenance And Inspection
Maintenance and Inspection When disassembling or removing the unit and its components, wait until the internal pressure equals atmospheric pressure and the CAUTION surface of the components have cooled to room temperature. Disassembling or removing components when hot or under pressure may lead to discharge of fluids, causing burns, other injuries or damage. - Page 37 As a general rule, periodic inspection should be carried out once every two years. (1) For maintenance of the following components, refer to individual instruction manuals. Instruction manuals can be requested from TLV or accessed from the TLV website. a) PowerTrap (GT14L) b) Steam inlet valve (bellows valve) (BE6H)

Page 56: 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 WARNING install a thermostatic mixing valve on the outlet. Failure to observe this precaution may result in burns, as hot water at a temperature higher than the set temperature may flow due to load fluctuations. - Page 57 For piping: (1) The pipe diameter should not be smaller than the diameter of the unit connections. (2) For steam piping, make sure the piping is connected with a downward slope on the downstream side. (3) The piping should be kept simple, with as few joints as possible in order to avoid pressure loss.
- Page 58 A. Cold water inlet, hot water outlet The cold water inlet and hot water outlet of the unit are connected to the inlet/outlet of the heat exchanger. Make sure to follow the installation procedures regardless of the instructions provided. These are the minimum precautions to prevent this unit from being damaged or malfunctioning.

Page 67: Commissioning Procedure
Commissioning Procedure When starting up the unit, make sure to check the display for the measured temperature and do not touch the hot water until the CAUTION temperature becomes stable as water at a temperature higher than the set temperature may flow. Failure to observe these precautions is dangerous and may result in burns. - Page 68 If blowdown has not been adequately carried out, TLV cannot guarantee against damage or performance loss of valves and the unit as a result of scale. (4) Make sure that the power supply indicator on the control panel is lit and the power is supplied to the control panel.
- Page 69 (Factory setting: 5 seconds). If the water flow rate does not stabilize within 5 seconds and the unit repeatedly starts and stops operation, the alarm delay time must be changed. Consult TLV on how to change settings.
- Page 70 If the water flow rate stabilizes quickly, the alarm delay time will be reduced. However, if using the unit at or around the minimum flow rate, the unit may repeatedly start and stop operation. Consult TLV if this situation applies. (6) Water temperature: The difference between the target temperature and the water temperature is normally ±1 °C, depending on the operating conditions.
- Page 71 (Even within the capability range described below, there are cases where water does not reach the target temperature depending on the temperature and flow rate conditions.) SQ2: 20 to 250 kW SQ4: 60 to 700 kW SQ6: 100 to 950 kW Do not change the temperature settings without contacting the user when washing hands, using a shower or cleaning.
