Installation
Piping must be performed before wiring.
Place the heater so that the front and top parts can be opened. Install connectors so that the heater can be easily moved for
inspection, cleaning and servicing
A check valve should be installed AFTER the heater and a shutoff valve BEFORE the heater, so that servicing of the heater can
be performed without emptying the swimming pool.
A bypass connection should be installed and adjusted so that the recommended flow through the heater can be achieved.
If several (2-10) MidiHeat devices are connected in parallel, each Midi Heat should have its own by-pass connection for easy
servicing.
Fix the heater on a flat horizontal floor/foundation with a screw/bolt through four Ø9 mm holes in the bottom.
Piping layout
Plug the heater into the pool system according to the flowchart below. The outlet may not be connected to any type of crane or
connections other
than those stated here.
The heater is equipped with connections G2¾” for binding PVC pipes with outside diameter Ø63 mm.
Note! Do not install a shutoff valve between the heater and the swimming pool (install check valve instead). Dosing of chlorine,
acid or similar must always be done AFTER the heater.
