HOW YOUR JETSPA SHOWER WORKS

1. Water is heated instantaneously as it flows

over the heating elements in the copper

cylinder (Diagram 6).

2. The heaters are only switched on when

sufficient water is flowing.

This is done automatically with a switch

which works on water pressure and is

indicated by the LED indicator illuminating.

3. The water is turned on and off by the

solenoid valve and Control PCB built into

the shower.

This is switched on when button "A", "B" or

"C" is pressed.

4. The flow of water is automatically held at

the level set by the user even though the

supply pressure may vary (see "Effect of

Other Water Devices on Incoming Water

Supply").

5. If the water supply falls below a set limit, the pressure switch will operate and switch off the

power to the elements. This is indicated by LED indicator going out (see "Effect of Other Water

Devices on Incoming Water Supply").

6. As a further safeguard, a thermal cut-out switches the power off if the water temperature

climbs above the set limit.

This cut-out, which gives an audible click, may also operate due to residual heat when the shower

is switched off. It will reset itself if water is run through the shower for 10 to 20 seconds.

7. The pressure relief device is to safeguard against abnormal pressure conditions, and provides a

level of appliance protection should an excessive build of pressure occur within the shower .

Effect of Seasonal Incoming Water Temperature Changes

The required water temperature is achieved by adjusting the rate of water flow.

Diagram 7 shows the principle involved in relating temperature rise to flow rate.

The higher the water rate the lower the temperature and vice versa.

The temperature of the water supplied from the mains can vary considerably

throughout the year from 5 to 20°C.

This means that in the winter, flow rate will be less than in the summer to

achieve the same outlet temperature.

In summer the "

power setting may give adequate hot water.

(Medium)"

In some winter conditions, it may be necessary to select the inner or outer spray pattern only of

your shower handset. This will ensure correct operation of the shower with a slightly lower flow rate.

Effect of Other Water Devices on Incoming Water Supply

Your shower is designed to stabilise temperature changes caused by water pressure

fluctuations. These can result from toilets being flushed or taps being turned on and off.

When this happens your showering temperature will be held within a controlled band, provided that

the minimum pressure required by the shower is maintained.

Your shower requires a minimum running pressure of 69kPa (0.7 bar, 10 psi).

At pressures above 69kPa (0.7 bar, 10 psi) it will minimise temperature fluctuations as detailed

above. If the water pressure falls below 69kPa (0.7 bar, 10 psi) it is likely that the pressure switch

will turn off the power to the heating elements, resulting in a cold shower.

HOW TO INSTALL YOUR JETSPA SHOWER

WARNING: ALL WIRING AND INSTALLATION MUST BE

SUPERVISED BY A SUITABLY QUALIFIED PERSON.

WARNING: DO NOT INSTALL THIS SHOWER WHERE IT MAY BE

SUBJECTED TO FREEZING CONDITIONS

We recommend that the installation is done in the following sequence.

a. Fixing the shower to the wall

b. Plumbing c. Electrical connections

a. FIXING THE SHOWER TO THE WALL

1. Position the riser rail at a convenient height for majority of users as

detailed in Diagram 1 and mark its position.

2. Position the heater so that the top of the unit is horizontal and level

with, or a maximum of 0.6 metres (2ft) below the top of the

riser rail. Choose a flat piece of wall to avoid the possibility of

distorting the backplate, as this may make the front cover a poor fit.

3. Adjust the position to get the most convenient arrangement taking

the following into account.

The heater must not be mounted in the direct spray from the handset.

The handset must not be able to come into contact with used water in the cubicle, bath or

basin. If it can, then a vacuum breaker must be fitted (available from us if required).

4. Fix the riser rail with screws provided.

The fixing holes at the base of the brackets will be disclosed by removing the plastic fronts.

See Diagram 4 and instructions supplied with accessories for further details.

5. If you have not yet done so, remove the front cover assembly by undoing the retaining screws at

the top and bottom of the unit and lifting the cover off.

6. Your shower unit not only accepts services from the top, bottom or rear.

It also accepts services from the left or right hand side of the unit.

Decide the position of the electrical cable into the unit.

If top entry is chosen, cut away the walls in the backplate as shown in Diagram 2a.

If bottom entry is chosen, cut away

the walls in the detachable bottom

section as shown in Diagram 2b.

The detachable bottom section is

secured to the backplate by 2 screws.

7. Decide the position of entry of the

cold water pipe into the unit.

If top entry is chosen,

cut away the backplate as shown in

Diagram 2a.

If bottom entry is chosen, cut away the

walls in the detachable bottom section

as shown in Diagram 2b.

If rear, please read the section on plumbing. To aid installation, you may find it convenient to

move the flexible pressure relief valve outlet assembly by removing the two securing screws.

If you do, please ensure that they are fully tightened on re-assembly (see Diagram 2b).
