Showertimer is a patented electronic device which cuts off the water supply after a pre-determined time period during which the unit provides visual progress monitoring and audible warnings.
There is an enforced waiting period between showers which prevents an immediate follow-on shower.
Both shower time and waiting time are programmable by the owner. The two time periods can be selected and set by the owner from a number of pre-programmed time options. Shower time can be selected in whole minutes from 0 up to 12 minutes and the Waiting time between showers can be chosen from 0, 15, 30, 60 or 120 seconds.
Features
• 12 Volt DC safety approved power supply. No batteries to replace.
• Strong stainless steel or polycarbonate box.
• Solenoid valve has watermark approval
• Single press button operation.
• Easily programmed by the owner.
• 2 digit green LED display.
• Powerful beeper for audible warning.
• Steady display of shower time.
• Flashing display of waiting time.
• Installed at the shower outlet.
• Easily fitted to most existing showers.
• Requires mains (or equal) pressure hot water.
• 12 months warranty.
• Made in Australia.

INSTALLATION INSTRUCTIONS for the Electronic Shower Timer Mark II.
Electrical
•The 12 V DC Power Supply 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 please refer to the NOTE at the end of the programming instructions.
•The power pack comes with 1.8m of lead with a 2 pin socket on the end into which the back of the cylindrical plug is fitted.
TIP: To avoid losing the plug during the process of running the lead through wall cavities, etc. Remove it and plug into the PCB for safe keeping.
•If the power cable is to come through the wall, be aware of water pipes when drilling around the shower area. Damage can be expensive.
•The lead should enter the shower area within the confines of the shower timer box. It may be possible to enter next to the shower outlet pipe.
•To come down the wall externally from the ceiling, the plaster/rendered wall can be channelled out or surface ducting can be used.
•The cylindrical plug on the power supply lead fits into a socket on the Printed Circuit Board (PCB). This circuit is polarity conscious. That is; it will not operate if the positive and negative are reversed.
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 (See Fig 1). The display will light up and should alternate between “05” and “15”. These are the factory settings – 5 minute Shower time and 15 second waiting time between showers. If no display, remove the plug and reverse the connection. The plug leaves the factory with correct polarity. It may be opportune to programme the timer now. (See programming instructions).
•Plug the PCB output leads on to the solenoid valve spade connectors as per Fig 2.
•Fit the box over the valve and be careful to allow room for the wiring. Keep it between the two mounting pegs.
See Figure 1 at bottom of page.
Plumbing
•HOT WATER SUPPLY MUST BE MAINS (OR EQUAL) 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 cycle. We recommend that the taps be turned off after each shower but some users will 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. The integrity of this plumbing has perhaps never been tested. Please be sure there are no leaking joints hidden in the wall, which will cause dampness in adjoining rooms, etc.
To install solenoid valve
•Remove shower arm. This valve fits ½” BSP male outlet pipe.
•Cut outlet pipe squarely and precisely 10mm from the wall surface (tiles?).
TIP: To ensure a square cut, use a nut or a sleeve as a guide for the saw. A 10mm thick board, maybe 40 mm wide with a 20mm hole will do the job.
•Carefully de-burr, flush and clean out the thread including old sealing tape, mortar, grout, etc. Thread must be in good condition as far back as the wall surface.
•Screw the valve on, counting 4 complete 360 degree turns. Turn valve further clockwise from this position until the coil is in the vertically down (6 O’clock) position (see Fig 1). Turning more than 5 turns will damage the valve.
•Remove the valve counting the number of turns
•Apply thread sealing tape clockwise to the thread of the outlet pipe.
•Refit the valve counting the same number of turns until the coil is at 6 O’clock. If it is not firm, remove and fit more sealing tape.
•Turn on a tap and inspect around the valve for any sign of a leak. Leave the tap turned on to ensure that it does not weep.
•Slip the box over the valve output nipple and check that the sides press firmly against the wall, particularly at the valve end. If not, check the body of the solenoid valve is flush against the wall surface. If not, you must remove the valve and trim a little more off the outlet pipe in order to achieve that.
TIP: Be sure that the wires are located between the two mounting “pegs” rather than caught under one of them.
See Figure 2 at bottom of page.
To fit the box
•Turn tap off. Carefully plug 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. The display will light up. If not, remove the plug and reverse the connection. See electrician’s instructions.
•Plug spade connectors onto solenoid valve. The 90 degree connectors must be fitted so as to direct the wires toward the wall. (See Fig 2). Beware; some water may come out if timer is running.
•Slip the box over the output nipple of the solenoid valve. Carefully ensure that the wiring is not obstructed within the box. It must be between the mounting pegs.
•The solenoid valve will locate the box vertically
•Fit the thread seal tape, flange and screw on the shower rose. Do not over tighten!
TIP: A trial fitting prior to fitting the thread tape will indicate the number of turns required.
•Hold the box firmly while screwing the shower rose on to the nipple.
•The shower rose/flange will hold the box against the wall.
• Start the timer, turn on water tap and check for leaks at the output.
Where added security is needed the box can be screwed to the wall through the two access holes in the front.
•Tap out the blanking plugs on the front of the box by pushing through the screw holes from the rear.
•Mark the wall for the mounting screws.
•Remove the box, drill the wall and use 6 gauge stainless screws. If there is any doubt about the presence of water pipes, use double sided adhesive tape or silicon to secure the box to the wall rather than screws. (See Fig 1)
NOTE: If the “swinging arm” model of shower is used we recommend that the box be screwed to the wall for extra support. Nevertheless, damage to the solenoid valve is possible if the arm is raised or lowered without loosening the friction nut. Such damage will not be covered by our warranty.
Warranty: Showertimer carries a guarantee against defects in materials or workmanship for a period of twelve months from the date of purchase (90 days for commercial or industrial installations).
Pricing Includes GST.
Delivery by Registered Post @ $15.95 Australia wide will be added at checkout.
