Vent Stacks
The main task is the installation of the vent stack, which is included with all units. The vent kits included in the shipping carton are sufficient for installation in most single story buildings. If more is needed they are normally easy to find. All vent pipes are thinwall PVC. For more vent stack installation information, click here.

Electrical
All electric units are supplied with a power cord and plug which connects to a standard (3) pin 115 Volt outlet and powers both the fan and heating element. 12 Volt fans for non-electric models can be installed in-line with the stack, and connected to a battery which draws from an alternate source of energy, such as a solar panel.
It is recommended that all units be installed on a GFI (Ground Fault Interrupt) circuit to protect your unit from power surges.

Drains
Electric units include ½" emergency safety drains. These should be connected if heavy use, residential use or power outages are anticipated. NE (Non-electric), AC/DC, SPACESAVER and Sun-Mar Mobile units are all fitted with 1" drains, which should be connected to an approved drain pit, container, or other facility.

Winter Use
SUN-MAR units serve as a reliable year-round facility when prepared for continuous or periodic use during the cold winter months. If you use your cabin only once in a while in the winter, the unit may be used as a holding tank during this time. If your SUN-MAR will be in use every weekend in the winter, or in a residence, the temperature must be kept above 55^o F at all times to keep the compost going.
