TCH-150 & 460
LOCATION:
The cabinet can operate at temperatures up to 80ºC with high humidity (see control envelope page
8). Therefore it should placed in a well ventilated area away from sensitive equipment that may be
affected by the local heat and humidity.
Since ambient air is usually drawn through the cabinet, the operating range of the cabinet will be
greatly affected by the ambient temperature and humidity. It is best located in a stable air
conditioned environment.
The cabinet is provided with castor wheels so that it can be easily moved around.
Allow sufficient space around the cabinet to provide adequate ventilation. We recommend a space
of 30cm on both sides and 10cm at the rear. In particular, make sure that the ventilation slots
around the top of the cabinet are not blocked off or restricted in any way.
Ensure that there is sufficient room in front of the cabinet to allow the door to open.
SERVICES:
ELECTRICAL:
Confirm that the power supply is suitable for this equipment.
Refer to the equipment rating plate for details:
TCH-150:
10 amps
240 volts
50Hz.
TCH-460:
15 amps
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.
WARNING:
Ensure that the electrical outlet is earthed, is the correct voltage, and
capable of carrying the stated current.
Model TCH-150 is suitable for bench top or floor use, whereas the TCH-460 is
suitable for
floor standing only.
These cabinets are not suitable for stacking.
WATER:
A water supply is required for the humidity trough inside the cabinet. The connection for the water
supply is found on the right hand side of the cabinet.
Since the water level is automatically regulated, the water supply can come from either town water
or from a gravity fed water reservoir.
If the water supply is town water, we recommend that it should be filtered to prevent the build up of
mineral salts frequently found in town water. The water in the humidity trough is constantly being
heated, and therefore evaporation will leave mineral deposits behind.
An alternative method,
and one that we recommend
, is to use a water supply from a gravity fed
tank. Thermoline supply an optional 25 litre water tank complete with hoses and connection fittings.
This tank should be elevated by at least 1 metre and filled with water, the 25 litres would last at
least 2 to 3 days even under the worst operating conditions.
The gravity fed water supply has a number of advantages over a town water supply:
•
Firstly, the water in the tank can be “treated water”: such as distilled water or deionised
water. The deionised water does have the potential under certain conditions to corrode
stainless steel (refer to “caring for stainless steel” on page 18). Using distilled water will not
