2.0 INITIAL INSTALLATION

2.1 EQUIPMENT SUPPLIED

After unpacking the instruments, check that all parts of the system are present. The boxes

should contain:

1 Controller NTE-2A with AC line cord

1 Thermal Probe

1 Water Pump and Tank Unit, PTU-110A, with 2 water tubes and

AC line cord

1 Operating Manual

2.1 WATER PUMP AND TANK UNIT

Unscrew cap. Fill reservoir with two and a half gallons of distilled water. Add 2 teaspoons or

one tablet of a dehumidifier treatment to prevent the formation of algae in the tank or tubing.

DO NOT OPERATE PUMP UNLESS TANK HAS BEEN FILLED WITH WATER.

PUMP MAY BE DAMAGED IF RUN DRY.

The AC line cord should be connected to the SWITCHED OUTLET on the rear of the

controller. This ensures that the water is always flowing when the controller is turned on.

Check water level periodically during operation to ensure that water level is within three

inches of the lip of the container.

To prevent spills, all water connections are automatically self-sealing when disconnected.

The pump in the PTU-110A Pump and Tank Unit is self-priming. When first started, it will

be noisy for five or ten seconds. This is normal. After the initial clatter, it should operate

quietly and continuously. Occasionally, small air bubbles may collect inside the pump and

result in a buzzing sound. If this becomes unacceptable, we recommend the following

procedure: Check that the tank cap is securely screwed down. Hold the handle on the front of

the unit (the panel with the label) and tilt the whole unit backwards so the label faces up.

The pump will begin to clatter when it is ready to re-prime itself and will stop when returned

to the upright position. Normal operation will then resume.
