Shower Timer Stainless Steel - Commercial Model
Save $$$ with this Accurate Water Saving Device! (Also available in White Powder Coated See SKU P15)
The Shower Timer Product
Shower Timer is an electronic device for controlling the shower time, thus reducing peak hour queuing and saving water and heating energy.
Shower Timer uses patented microprocessor technology.
Shower Timer terminates the shower after a pre-determined time and that is followed by a “discouraging” shower prevention or waiting period.
Shower Timer is easily programmed by the owner for shower and shower prevention times between 0 and 12 mins.
Shower Timer is contained in a strong stainless steel box located at the shower outlet.
Shower Timer is easily installed as a retrofit with no alteration to existing plumbing.
Shower Timer has a visual display which counts down the minutes and seconds remaining.
The visual display in Shower Timer is supported by an audible beeper.
Shower Timer is supplied with a low voltage safety approved
power supply.
Cost of Showering
Most showers, at a comfortable temperature (40°C), will deliver water at more than 12 litres per minute. At a comfortable temperature, that heated water can cost as much as 10 cents per minute. Shower Timer can be used in conjunction with a water saving shower head to save on both time and flow rate.
The heating energy required to provide the comfortable temperature depends on the ambient temperature and the energy source used. (Gas or Electric, Natural or LPG, Full Tariff or Off-peak, Solar, etc.)
A 12 minute shower with a flow rate of 12 litres per minute heated by LP Gas from 15 degrees Celcius will normally cost about 90 cents in an Australian city location. Shower Timer can save half this cost.
Cost Savings
Most people spend much more time than necessary under the shower.
The family average time is often more than 12 minutes. Six minutes is generally more than adequate. Shower Timer can limit each shower to six minutes duration.
A family paying 90 cents for each of 5 (12 minute) showers daily will SAVE OVER $800 per annum in water and heating costs by installing a Shower Timer set to 6 minutes.
Under the same conditions, a family having ONLY 3 DAILY SHOWERS will recover the purchase and installation of a Shower Timer in less than 12 months.
After this time they will be SAVING money, year after year.
Shower Timer Installation Instructions
Plumber’s Instructions
HOT WATER SUPPLY MUST BE MAINS PRESSURE, OR EQUAL TO THE COLD WATER PRESSURE.
SHOWER OUTLET PIPE SHOULD BE PERPENDICULAR TO THE FINISHED WALL SURFACE.
PIPES MUST BE FLUSHED OUT TO REMOVE IMPURITIES OR THE SOLENOID VALVE WILL MALFUNCTION.
The solenoid valve will cut off the water at the completion of the shower cycle. Many users will therefore not turn the taps off. This will result in the riser pipe between the taps and shower outlet being under pressure for the first time and for long periods. Please be sure there are no leaking joints hidden in the wall, which will cause dampness in adjoining rooms, etc. We accept no responsibility for this potential problem but urge you to check the integrity of that plumbing.
TO INSTALL BRASS SOLENOID VALVE
Remove shower and dome flange plate.
Cut ½” BSP male outlet pipe squarely 15mm (max) from the finished wall surface (tile?) and de-burr.
Carefully clean out the thread including old sealing tape, mortar, grout, etc. right back to the finished wall surface or even further if possible. Thread must be clean and in good condition.
Turn on the tap to flush out the outlet pipe. Metal filings and other impurities may cause the solenoid valve to malfunction.
Screw the valve fully on by hand and note the position of the “coil” (black plastic) part of the valve. Back off to the 7 O’clock position as shown in Figure 1.
Push the coil against the wall. The coil will then be at an angle to the valve body as shown in Figure 2.
Try fitting the box over the valve. The box should press firmly against the wall. If not, you must turn the valve another full turn. You may need to cut away the cladding (tiles) around the outlet pipe.
Unscrew the valve, counting the number of turns until it comes off the pipe.
Apply sealing tape to outlet pipe. The tape must not “bunch up” as the valve screws on but must seal the full length of the thread.
Screw the valve on, counting the same number of turns achieved in the trial fitting. If you go past the 7 O’Clock position the box cannot be fitted over the valve. At the 6 O’Clock position you will not have screwdriver access on the right hand side.
Turn on the cold tap and inspect around the valve for any sign of a leak. To be sure, leave the tap turned on.
Electrician’s Instructions
Our 12 V DC Power Pack is double insulated and complies with AS1044 (Approval No. Q99505). It is normally located in the ceiling above the shower cubicle and permanently “on” but for a user friendly domestic situation, please read the NOTE at the end of the programming instructions.
The power consumption of the unit when operating is less than 15 Watts. For a single installation, the power can be drawn from a light fitting.
For a multiple installation (such as a caravan park) each timer will normally have a power pack in the ceiling above each shower or in an adjoining room. If required, a “no break” power supply is available using a 12V wet cell battery and double insulated full time charger instead of a separate power pack for each shower. Each timer will draw less than 1 Amp from the 12 Volt supply.
The power pack normally supplied comes with 1½ metres of lead and a reversible plug on the end. We recommend that you remove the plug (See Figure 3) so that it is not lost, for example; in a wall cavity. It could be securely stored in the printed circuit board (PCB) socket.
Having run in the power lead, refit the plug and insert it into the socket on the PCB (See Figure 4). The timer is polarity conscious. If the display lights up and alternates every 3 seconds, the polarity is correct. Otherwise the display will not light up at all.
If ducting is to be used it should enter the timer box from the top, left hand side. Spanner access to the solenoid valve must be available through the top of the box between the middle and right hand side.
If the power cable is to be hidden in the wall, be aware of water pipes when drilling around the shower outlet.
To Install the Box
Access holes for a screwdriver are provided in the front of the box (See Figure 5) and there are two screw holes provided in the rear of the box to suit 8 gauge stainless steel screws.
Fit the box over the solenoid valve. With the box vertical, mark the screw positions on the wall.
Remove the box and drill for plugs. Beware of water pipes when drilling into the wall. If in doubt, use silicon in lieu of screws.
Double check that there is no sign of water weeping from the valve inlet. The interior of the box must be dry. Turn taps off.
Carefully plug the power lead into the socket on the printed circuit board. Squeeze plug and socket between two fingers and thumb to ensure that the plug is fully home. About 3mm of the plug will remain outside the socket as in Figure 4.
The display should light up and alternate every 3 seconds between the shower time setting and then the shower prevention time setting. If the power is on and the display does not light up, the polarity is probably reversed. The concentric plug on the power lead has a two pin plug/socket connecting it to the power lead. Unplug that, reverse it and try again. [See Figure 3].
It may be opportune to programme the timer now, before fixing the box to the wall, while the power can be easily removed and reconnected (See “Programming instructions”).
Plug the electrical socket onto the solenoid valve ensuring that the rubber seal (washer) is in place. Beware; the valve may open, releasing some water. Secure the socket with the screw provided.
N.B. The coil on the solenoid valve MUST be pushed back against the wall and the securing nut on the end of the coil should then be gently tightened. [See Figure 2]. Failure to do that will result in serious damage to the printed circuit board which will not be covered by warranty.
Pushing the “Start” button with a tap turned on should allow the water to flow out of the valve. Do not secure the box until this has been achieved.
The timer must run through “Shower time” and “Waiting time” before it turns off but the water can be turned off at the taps any time.
With the water running, check for leaks where the nipple screws into the solenoid valve outlet . Any sign of weeping here must be rectified.
Secure the box to the wall. Fit the flange, tape the output nipple and screw the shower arm/rose on, holding the valve body with a “flattish” 26 mm spanner (8 mm thick max.) through the gap between the wall and the top of the box. [See figure 5]
Peel off any remaining protective covering from stainless steel box.
Cover the screwdriver access holes with the green “dots” provided. Clean the box first with methylated spirits. These dots are adhesive backed but a smear of silicon will give better adhesion.
Shower Timer Programming Instructions
To enter programming mode, disconnect the power for 30 seconds. After the initial installation it may be necessary to remove power at the fuse box.
Within 2 minutes of re-connecting power to the timer, press the Start button and hold for 10 seconds. The buzzer will sound 2 beeps and the display will flash “P1”.
Repeatedly press the button to cycle through the program options in accordance with the table shown below. When the desired shower setting is displayed, press and hold the button for approximately 3 seconds (holding for 10 secs will take you out of programming mode). To confirm your selection, the buzzer will beep when you release the button and the display will cease flashing.
If you want to change the shower prevention time between showers, continue pressing the button to advance to the desired prevention time. Press and hold for approximately 3 seconds. (Buzzer will beep when you release the button)
When in programming mode, the display will flash on all except the two currently selected options.
Holding the button for 10 seconds will return the timer to Normal mode. Failure to press the button during any period of 30 seconds will also return the timer to Normal mode.
In the following table, the left hand column indicates the cycling sequence and the visual display. The other two columns interpret the display options into Shower time and Shower prevention time:
DISPLAY/ SHOWER/ PREVENTION
P1=1 min; P2=2 mins; P3=3 mins; P4=4mins; P5=5mins; P6=6mins; P7=7mins; P8=8mins; P9=9mins; P10=10mins; P11=11mins; P12=12mins.
00=No Shower; L0=No Waiting; 15=15seconds; 30=30seconds; L1=1minute; L2=2minutes.
NOTE: In a domestic situation the owner can choose to have the power supply manually switched on and off from within the bathroom. It could be associated with the exhaust fan (piggy back) and switched on and off with the fan.
In this case, the timer operates normally while the power is on but turning the switch off and on again resets the timer to Normal mode – ready to go again immediately.
