7| Accessories

Special accessories are only premounted in the factory if ordered specially by customer. Retrofitting is
possible in full compliance with the safety instructions and repair instructions enclosed with the kits.
Information about the use, operation, maintenance and servicing of the components is available in the
printed literature or on the internet under www.bock.de.

ATTENTION

Capacity-regulated operation alters the gas speeds and pressure

ratios of the refrigerating plant: Adjust the suction line routing and
dimensioning accordingly, do not set the control intervals too close and
do not let the system switch more than 12 times per hour (refriger-
ating plant must have reached a state of equilibrium). Continuous
operation in the control stage is not permitted.

We recommend switching to unregulated operation (100% capac-

ity) for at least 5 minutes per capacity-regulated operating hour.
An assured oil return can also be realised by a 100% capacity
requirement after each compressor restart.

Electrical actuation of the solenoid valve: Normally open, (cor-

responds to 100 % compressor capacity).
