Intended Use
The Thermoline TU-1500-B heater circulators are designed to operate between ambient +5°C and 95°C. The TU-1500-B heater circulator offers an industry standard for temperature control in uncirculated baths.
- Control Accuracy: +/- 0.1°C
- Operating Temperature up to 95°C
Unpacking
- The TU-1500-B heater circulator will be delivered in a carton.

Moving
To remove the heater circulator from the bath, first switch off the power, then exercise caution with any residual heat or potential water spills.
Operating Environment
Heater Circulator Location
- Place the heater circulator away from direct sunlight and heat sources.
- Ensure the room's ambient temperature does not exceed the heater circulator's operational limits.
- Heater circulators must be stored indoors at all times. Failure to do so may result in a significant decline in water bath performance and potential damage to stored items.
- When not in use, ensure the unit is powered down and stored out of the water.
Environmental Conditions
| Condition | Temperature | Humidity |
| Extreme Operating Environment | 10°C to 32°C | Up to 85% RH |
| Optimal Environment | 23°C (±5.0°C) | 50% RH (±25% RH) |
Electrical Connections
TU-1500-B circulators require a 10amp, 230V, 50Hz power supply. Use a dedicated outlet for the circulator, and avoid using power boards or extension cords. Each circulator is supplied with a standard 3-pin moulded plug for connection to the mains.
Power Supply:
-
TU-1500-B circulators come with a 2.5m attached mains power lead, featuring a three-pin plug. Ensure the circulator is positioned at a reasonable distance from the power supply.
Water Quality
For optimal performance, follow the recommended water quality parameters below. Due to the extensive use of stainless steel in Thermoline products, do not use deionised water. It can cause corrosion (due to leaching over time) that may not be covered under warranty.
| Parameter | Range |
| Resistivity | 0.1 - 0.5 MΩ |
| Conductivity | 2-10 µs/cm |
| Total Dissolved Solids | <10 mg/L |
| Acidity | 6-7 pH |
Avoid tap water if possible. Using tap water may significantly increase the required frequency of cleaning and maintenance of the equipment. Unacceptable water can cause excess scale build-up and mineral deposits, particularly in humidity systems. This, in turn, can cause heater failure and issues with oat switches. In water baths, corrosion due to insucient cleaning is the primary concern, with heater circulators and circulation pumps being the most signicant issue.
NOTE: All Thermoline equipment using water requires regular maintenance, inspection and cleaning. Six monthly for Humiditherm, Envirotherm and Climatron cabinets. Water baths will require much more frequent cleaning due to the ease of contamination in the water. Water should be changed for any signs of contamination.
Descaling may be required if the water used is continuously topped up to compensate for evaporation as this concentrates the mineral deposits in the water. The bath should be completely drained regularly and filled with fresh, clean water.
Operating Environment Warnings
- Heater circulators must be stored indoors at all times. Failure to do so may result in a significant decline in water bath performance and potential damage to stored items.
- Make sure to place the heater circulator evenly and flat in the bath.
- Water baths with heater circulators should not be used with flammable solvents. They contain components that may act as an ignition source.
- Water baths can heat water up to 95°C and may become hot to the touch, including optional lids. Handle with care.
