5.2 Hydraulic Connection
The connections for the primary and secondary circuits are located in the lower section of the
indoor unit. When making the hydraulic connections, the hoses supplied with the unit must be
used.
The mounting instructions supplied with the hoses and hose clamps must be
observed.
Cutouts in the base plate are provided through which the two hose pairs are passed.
The connections are accessible from the operating side (front side) of the indoor unit.
The connections on the right-hand side (indoor unit <=> outdoor unit) are intended for the
primary circuit and those on the left-hand side for the secondary circuit
(indoor unit <=> gantry).
After connecting the hose sets fill the system according to 5.3.1.
The safety valve opens when the safety valve threshold pressure is exceeded (if the
threshold pressure is fallen short of, the safety valve closes automatically) and the
medium is able to escape.
Use only the delivered water/glycol mixture as provided to fill the primary circuit. The
secondary circuit can be filled with tabbed water in compliance with the responsible Siemens
project manager.
