Instructions for inserting Chill Block assembly
1. Ensure all power is disconnected.
2. Slowly push the chill block assembly into the PowerCage. Ensure that the
stabs are aligned with their connectors at the back of the PowerCage. This
is difficult to see. When the stabs are properly aligned and in place, the
chill block assembly will be seated squarely and the support bracket should
be resting on the PowerCage base when positioned correctly.
ATTENTION: The chill block assembly is heavy and it is recommended
that two people pull the assembly out to avoid damage.
