Page 4: Product Warranty
When making a claim for repairs under warranty please state the model number and serial number. These are printed on the compliance sticker, normally found on the front of the cabinet. Our records will show when the cabinet was despatched and if the warranty claim is valid. 18-5-10 TCH-150 & 460... -
Page 5: Introduction
Remove the equipment from the packing material, and check that the delivery is complete. Delivery should include the following: • 1 x Temperature and humidity cabinet. • Stainless steel open wire type shelves (TCH-150 = 2 shelves, TCH-460 = 4 shelves). • 1 x Hose connection fitting. • 1 x Operating manual. -
Page 6: Location
240 volts 50Hz Note: Only the TCH-150 model plugs into a standard 10 amp power point (otherwise known as a general purpose outlet or gpo). The TCH-460 requires a 15 amp power point. You will notice that the plug has a large earth pin and will not plug into a standard 10 amp power point. -
Page 7: Drain
Note: Gravity fed water tank should be at least 1 metre above the ground, to provide a suitable head for the water to flow properly. • Once the cabinet is in position with all of the services connected, use the lock-down levers on the castor wheels to prevent the cabinet from moving. 18-5-10 TCH-150 & 460... -

If a town water supply is used it may be necessary to adjust the water pressure regulator. See the section in “maintenance” regarding adjustment of the pressure regulator. Photo 3: Access to drain valve. 18-5-10 TCH-150 & 460... -
Page 9: Function
P a g e • Plug the cabinet into the power point. Note: only the TCH-150 model can plug into a standard 10 amp, 240 volt power point, the TCH-460 requires a 15 amp, 240 volt power point. • You are now ready to use the cabinet! -

The air is humidified by a heating element in the water trough in the bottom of the cabinet at the back. The air is dehumidified by the addition of fresh ambient air through the air inlet on top of the cabinet. The humidity controller cycles the trough element on and off to maintain stable humidity. 18-5-10 TCH-150 & 460... -

Air Heating Element Safety: (Non Operator Adjustable): This thermostat is factory set to turn off the air heating element if the circulating fan stops. Humidity Heating Element Safety: (Non Operator Adjustable). This thermostat is factory set to protect the humidity trough element from over heating due to lack of water. 18-5-10 TCH-150 & 460... -

Thermoline product, the alarm will switch off all forms of heating if the actual temperature exceeds the set temperature by 2.0°C. This will be indicated by a red flashing indicator and a scrolling message of ‘Over Temperature’ on the bottom display of the controller. 18-5-10 TCH-150 & 460... -

Using the temperature control as an example, let us assume that the top display (PV operating temperature), is reading 37.0ºC, and your reference instrument is reading 37.2ºC. That is a calibration error of +0.2ºC. 18-5-10 TCH-150 & 460... -
Page 18: Adjusting The Calibration Offset
CAUTION: The Offset value with few exceptions is between –0.5 and +1.5. The need to use a value outside this range should be carefully considered. If in doubt, return the value to zero and recalculate the offset value. 18-5-10 TCH-150 & 460... -
Page 19: Maintenance
After flushing the trough it will take a while for the water to heat back up again and for the temperature and humidity to stabilise. You should perform this procedure every 3 months if town water is used, less often if distilled water is used. 18-5-10 TCH-150 & 460... -
Page 20: Water Flow Adjustment
• Pull the water regulator knob towards you and turn it anti-clockwise until the float switch “bounce” is reduced. Note: If you turn the regulator fully anti-clockwise the water supply will be turned off. 18-5-10 TCH-150 & 460... -
