Air vents
must
be installed at the
highest point
in system piping where large air bubbles
might collect.
4.0 Wiring Requirements:
4.1 Power Supply:

Supply wiring must be sized according to local codes and the technical data provided in the
chiller manual.

Wiring must be routed through the cut-outs provided in the baseplate, and compressor
mount. To protect your wiring, all wires should pass through the rubber grommets.
4.2 Grounding:

Proper isolation of the wiring for the control and power circuits, and shielding of cables is
required.

A large contact area is necessary for low-impedance grounding of HF interference. As such,
the use of grounding straps instead of cables is advised.

Moreover, cable shields must be connected with purpose-made ground clips. The grounding
surface must be highly conductive bare metal. Remove any coats of varnish and paint.

The grounding wire must be sized in accordance with local regulations, and at minimum, the
same gauge wire as connected to the main power supply. The grounding must be an “isolated
ground” and must be connected to the ground terminal in the main electrical cabinet of the
chiller. The ground resistance must be less than 5 Ohms.
