DRAINAGE PIPE INSTALLATION
Ensure that the drainage pipe used has sufficient insulation to prevent condensation forming
on the pipework.
As the drain is gravity fed, it must decline at a slight angle (2/100) with no twisting or bending
to aid drainage.
The maximum length of the drain pipe must not exceed 20m, and must be suitably supported
to prevent bumps and bends.
Ensure that pressure is not placed on the pipe, as this may restrict the flow of condensate from
the unit.
The flexible hose must be mounted horizontally.
We advise on the following materials to be used:
Drain Pipe
Polyvinyl chloride pipe (32mm outer diameter)
Heat Insulation
Foamed polyethylene insulation plate (10mm thickness)
Use polyvinyl chloride glue at any connection points to prevent water leakage
Place glue over the front 40mm of the pipe before inserting it into the transparent pipe.
Allow 10 minutes for the glue to dry before placing any pressure on it.
