(A) Facilities to be provided in the Hydraulic Power Pack Room.<br />
Hydraulic power pack shall be installed in room where adequate provisions are<br />
made to keep ambient air free from dust, moisture <strong>and</strong> ambient temperature<br />
shall be kept below 35 0 C.<br />
Adequate facility shall be provided <strong>for</strong> h<strong>and</strong>ing of equipments/ components<br />
installed in the power pack room.<br />
