Maintenance Instructions

Introduction to the basic maintenance and responsible use
Ensure your Sun-Mar system operates perfectly year in and year out, with some basic care and common sense.
Please bear in mind that any composting toilet can be neglected and abused. It is in these circumstances that accessing and inspecting the composting chamber is crucial. It is good to know that fixing problems that may arise from miss management or otherwise can be sort effectively and without expensive service-men, as you can do it all on site by following the systems manuals or contacting us for support.
The unique design of the Sun-Mar - developed in Canada - employs traditional proven composting.
Simple to operate and maintain, the Sun-Mar is a balanced system that can deal with a range of requirements and with extended compost removal periods the system is a breeze.

SUN-MAR COMPOSTING SYSTEMS
An outline of how to look after a Sun-Mar is given below. This is to give you an idea of what is involved and to assist you in deciding on the ideal waterless composting toilet solution for your needs. Our team are happy to discuss your specific requirements and associated maintenance needs in more detail, so please contact us if required.
If you have just purchased a Sun-Mar system, please see here [link] for the basics of how to start your system.

USE + MAINTENANCE
HOW SIMPLE IS THAT!
There are only two things that you must do on a regular basis when it comes to maintaining your Sun-Mar composting toilet system. You will need to add bulking material (approximately a cupful per person per day) and rotate the drum.
The drum rotation is a periodic task which ensures that, when it comes time to empty the compost, you won’t have to deal with any fresh waste. You will need to rotate the drum backwards when it is approximately half full. This will empty the compost into the finishing drawer. It is best to leave the compost in the finishing drawer for approximately 7 weeks so that the compost can continue to process.

Maintaining a Sun-Mar Composting Toilet
Any cleaning? Not as much as you’d think
The waterless and micro-flush toilet pedestal are designed to be cleaned less often than a standard 4-6L flushing toilet. The micro-flush pedestal has a self-cleaning ball valve that generally takes care of the job for you. Cleaning of the toilet seat itself is done with a natural cleaning product called Ecogreen Toilet and Urinal cleaner. The product's enzymatic action also helps compost break down and eliminates odours. A bottle of Ecogreen Toilet and Urinal cleaner is provided with the toilet in the starter pack.
This cleaner can also be used in the evaporation chamber at the bottom of a system, where every 3 months (if the system is used full-time), the small rake provided should be used to remove any debris in the evaporation tray at the bottom of the unit.
Adding bulking agent/mulch & rotating the Bio-drum
These are the only activities you must perform on a regular basis when it comes to maintaining your Sun-Mar composting toilet system. You will need to add bulking material (approximately a cupful per person per day) and rotate the drum. Sample bags of the bulking material (sugarcane mulch mix) are provided with the toilet and can be sourced from landscape/garden supply stores. Peat-moss or COCO Peat can be added to the bulking agent to increase the moisture level if the compost is drying out too quickly.
Removal of Compost
The drum rotation is a periodic task which ensures that, when it comes time to empty the compost, you will have produced nice compost. The handle of the Bio-drum on the Centrex, Excel and Compact should be rotated clockwise every second day when the toilet is in use. You will need to rotate the drum backwards when it is approximately half full. This will empty a portion of the compost into the finishing drawer. It is best to leave the compost in the finishing drawer for approximately 7 weeks so that the compost can continue to process. Note: handle rotation for the Centrex 3000 run clockwise only.

The installation and maintenance manual provided with the toilet outlines these activities and we also provide customer support Monday to Friday on 0800 022 027, should you have any questions unanswered in this material.

Short Notes for use of the self-contained, on-floor models.
• If you simply urinate in the toilet, deposit your toilet paper, close the lid, and walk away…your job is done! If the toilet is being used predominantly for urination, be sure to add at least one cup of WCT SUN MIX and WCT MICRO MIX per user a day.
• If you make a more substantial contribution, deposit your toilet paper and one handful of WCT SUN MIX into the drum of the toilet. Close the lid and walk away!
• Every other day, turn the handle to mix and aerate the compost. Pull the handle from under the seat and turn in a clock-wise direction only. Open the lid of the toilet seat. Watch as the drum turns. The opening in the drum should come to the top of the drum 6 times. Once you have completed turning the drum. Fold the handle back under the seat, close the toilet seat lid and you are done.
Weekly maintenance (every second day):
• Turn drum to reveal waste inlet hole through access port and add WCT SUN MIX at the rate of 1 cupful per person per day. Rotate handle clockwise to mix contents of Bio-drum and give 6 complete revolutions of the drum (36-40 rotations of the handle). Ensure that the drum door opening is in the vertical position at the end after hearing the 'click' of the catch. Spray Ecogreen Toilet and Urinal cleaner into the drum before and after mixing.
• CHECK THE VOLUME OF THE BIO-DRUM™ To speed up composting, add one scoop of WCT MICRO MIX every second week, and ensure that the drum is not more than ½ full.
Bi-Monthly maintenance and emptying cycle:

• Remove the finishing drawer and rake out evaporation chamber with rake provided (the area below the finishing drawer). Clean the drum screen.
• Spray the drum screen with Ecogreen Toilet and Urinal cleaner and let sit for 15 minutes (this will help soften the debris before cleaning). Scrub the screen vigorously with a hard brush to clear the drain holes on the drum for future reliability.

KEY TO System Fixture (toilet) types.
There are two types of Split Systems
Wet systems: Toilet pedestal with a 500mL micro-flush moves solid waste within the narrow waste pipe that runs almost horizontally. Available on Sun-Mar Centrex models only.
Dry systems: Use a waterless toilet pedestal with a wide (250mm) waste chute of a variable length that sits in-line between the compost chamber directly below the bathroom floor.
