The hydraulic specifications of the unit are particular to your requirement
and are determined by computer selection: Loss of pressure of the wa
-
ter/water flow. Refer to the selection for sizing the valve, accessories, and
pump.
The connection of the piping to the coil must not impose any mechanical,
vibration or thermal (dilation) constraints.
The coils are delivered already threaded at the ends.
During the tightening of the coil thread, hold the tubing with the aid of a
wrench to prevent the tubes being damaged by twisting.
Respect the water entry and exit directions indicated on the labels glued
to the coil panel(s). Water and air directions must be opposite to get max
-
imum thermal performance.
All the water coil headers are 1” diameter with a male pipe thread at the end. An adaptater is provided for
the valves mounting :
•
F26x34-M15x21 for KSCR 08,
•
F26x34-M20x27 for KSCR 18, 28, 38 and 52.

A change-over thermostat (THCO) is to be installed on the hydraulic network and connected to the elec
-
trical cabinet of the unit. It allows mixing valve control to be inverted in installations with only one coil,
according to the fluid temperature detected at valve inlet.
