Abstract

Equipment and methods facilitating suitable orientation of salt-water chlorinators (SWCs) relative to the gravitational field of the Earth are detailed. So orienting an SWC in this manner reduces risk that the volume defined by its gas trap would not be accessible to hydrogen gas generated by the SWC in use. An accelerometer may be employed in connection with the SWC to assist in assessing orientation of the SWC relative to the gravitational field of the Earth.

First claim

What is claimed is:

1. A salt-water chlorinator configured to be installed in a water-circulation system of a pool or spa, comprising:
a. a body defining a water inlet and a water outlet;
b. an electrolysis cell positioned within the body; and
c. means, comprising an accelerometer, for determining orientation of the body relative to the gravitational force of the Earth as installed in the water-circulation system.

2. A salt-water chlorinator according to claim 1 in which the body has an upper portion defining an internal gas trap, further comprising means for indicating that the internal gas trap, as installed, is oriented as to be accessible to hydrogen gas generated during operation of the salt-water chlorinator.

3. A salt-water chlorinator according to claim 2 in which the means for indicating is responsive to at least one measurement made by the accelerometer.

4. A salt-water chlorinator according to claim 3 in which the means for indicating comprises a light configured to illuminate when the accelerometer measures a tilt of the body relative to ground of no more than ±10°.

5. A salt-water chlorinator according to claim 4 further comprising means for preventing operation of the electrolysis cell when the accelerometer measures a tilt of the body relative to the gravitational force of the Earth of greater than ±10°.

6. A method of installing a salt-water chlorinator in a water-circulation system of a pool or spa, comprising:
a. connecting an inlet and an outlet of a body of the salt-water chlorinator to other components of the water-circulation system; and
b. evaluating an indicator of the body whose status is responsive to at least one measurement made by an accelerometer of the body.

7. A method according to claim 6 further comprising adjusting orientation of the salt-water chlorinator relative to the gravitational force of the Earth so as to change the status of the indicator.

8. A method according to claim 6 in which the at least one measurement made by the accelerometer of the body is used to determine whether the body is tilted.

9. A method of installing a. salt-water chlorinator in a water- circulation system of a pool or spa, comprising:
a. connecting an inlet and an outlet of a body of the salt-water chlorinator to other components of the water-circulation system; and
b. evaluating an indicator whose status is responsive to at least one measurement made by an accelerometer on the body.

10. A method of installing a salt-water chlorinator in a water-circulation system of a pool or spa, comprising:
a. connecting an inlet and an outlet of a body of the salt-water chlorinator to other components of the water-circulation system; and
b. evaluating an indicator whose status is responsive to at least one measurement made by an accelerometer in the body.
