Note: Use only non-corrosive materials.
Step 2b – Bedding preparation and tank placing
• Level and compact the material used for the base.
• Handle the holding tank using the rope on the top.
•
Put the holding tank in place.
•
Make sure to put the inlet and outlet in the right place.
Step 3 – Connecting the holding tank
• Hook up the plumbing connections at the inlet of the holding tank.
• All holding tanks must be ventilated using a pipe at least 100 mm (4") in
diameter or one that is connected to the dwelling's ventilation pipe.
Step 4 – Initial backfill
• Backfill up to the shoulder of the holding tank.
• Note that the backfill material must be deposited and not dumped. As
such, a bulldozer should not be used.
• The backfill material must not contain any organic matter or impervious soil,
stones, debris or particles larger than 20 mm (¾") or any object that could
damage the holding tank.
Note: It is essential to backfill evenly each side of the holding tank.
Step 5 – Extra riser installation
Proceed as follows to install an extra riser:
• Clean the rim of the holding tank access (where the 4 holes are located for
the lag screws).
• Place the rubber seal on the access rim.
•
Put the riser in place, aligning the holes in the base of the riser with the
cavities of the riser preassembled on the tank.
•
Tighten the riser in place using the 4 lag screws and washers provided for
this purpose.
Step 6 – Final backfill
• Before the final backfill, it is strongly recommended that the holding tank
and access be insulated to prevent freezing. Insulating panels should be
used for this purpose.
• Backfill up to the desired level.
•
The thickness of the backfill over the holding tank must not exceed 90 cm
(36").
• The PSR-060 riser is provided and must be used.
• Secure the lid onto the holding tank or onto the riser using the supplied
lag screws.
