Piping materials
Do not use the following interconnecting piping materials in a closed water system:
•
Oxidizing biocides
•
Aluminum components
•
Brass components with high levels of zinc
•
Non-stainless steel iron components
Water precautions
Take the following precautions before installation of the HP POD:
•
Verify that all foreign matter and particulates are flushed from the system. Water might be discolored
during the initial flushing of the system. Clear running water is the sign that all foreign matter and
particulates have been flushed from the system.
during the initial flushing of the system. Clear running water is the sign that all foreign matter and
particulates have been flushed from the system.
•
Evaluate the short-term and long-term system requirements against the available water capacity.
•
Ensure that the chilled water loop is properly designed for liquid cooling systems and is separate
from the sanitary water systems in your building (bathroom, sink, drinking water).
from the sanitary water systems in your building (bathroom, sink, drinking water).
•
Ensure facility managers are aware of the additional load being added to the chilled water supply of
the building. Be aware that the added heat load might affect other components being cooled by the
chilled water plant.
the building. Be aware that the added heat load might affect other components being cooled by the
chilled water plant.
Condensation management
CAUTION:
During operation, avoid leaving the HP POD doors open, to maintain accurate
environmental conditions inside the HP POD.
Supply cooling water that is above the dew point inside the HP POD to prevent condensation forming on
the heat exchangers.
The heat exchanger drip tray collects any condensation that forms on the heat exchangers. This collected
condensate drains out of the HP POD through the heat exchanger condensate drains. HP recommends
connecting condensate drains on the HP POD to a facility drain to prevent collection of water near the HP
POD.
There are three 1.91 cm (¾ inch) condensate drain outlets are across the rear of the HP POD directly
connected to the heat exchanger drip trays. There are two drains for the water main supply and return
lines located on the front of the HP POD.
To avoid excessive buildup of condensate and to conserve energy, raise the cooling water temperature to
above the dewpoint to manage condensation while maintaining the necessary cooling capacity.
