Site requirements
About this document
This document outlines the installation requirements for a 12 m (40 ft) HP POD. These guidelines are for a
qualified architectural or consulting engineering team to generate site-specific documents for each HP
POD installation. The site-specific installation documentation must comply with local building code
jurisdictions.
Site preparation
The HP POD must be installed on a surface capable of supporting approximately 50,456 kg (111,000
lb). The site location for the HP POD must be level +/- 0.5 degrees tolerance. Appropriate clearance for
installation, service, and system utilities (power and water) must also be considered.
IMPORTANT: Before installing the HP POD, consult your local AHJ for applicable codes and
to review site-specific location guidelines.
IMPORTANT: The HP POD is designed for ground level installation. If you install the HP POD
on an elevated surface, make sure the minimum height requirements for circuit breaker
actuators are considered per local and national electric code requirements.
The area in front of the outside panels must include a work platform. The distance from the
work platform surface to the center of any circuit breaker actuator handle must not exceed
183 cm (72 inches). The platform must be a minimum of 91 cm (36 inches) wide for free air,
and if the platform construction is grounded metal, must be a minimum of 107 cm (42 inches)
wide.
Safety information

Water quality requirements
Water quality requirements and specifications
•
Closed-loop water must not contain any lime scale deposits or loose debris.
•
The chilled water temperature to be supplied to the HP POD must be 12º to 24ºC (55º to 75ºF).
NOTE: Freezing water might cause a blockage and damage to the unit. In outside locations
subject to freezing temperatures, an additive such as glycol might be necessary to lower the
freezing point. However, since the heat transfer potential of water with glycol is lower, the HP
POD must be derated accordingly.
NOTE: The water cycle must be drained completely, and then purged using compressed air
when storing or transporting at or below freezing temperatures.
Acceptable water quality specifications
Water must be maintained per the following acceptable water quality standards.

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.
•
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).
•
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.
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.
Water quality requirements
13
Power management
Connection requirements
When determining the final location of your power and water connections, consider the distance between
the facility utilities and the HP POD.
The facility power connection must be installed in compliance with local electrical codes and regulations.
HP reference electrical installation design is based on a maximum distance of 15.2 m (50 ft) or line of
sight between the switchboard and the HP POD.
HP can provide engineering services to develop the site installation plan and drawings as a supplemental
service.
All 3-phase HP POD feeders require that the neutrals and the equipment grounding conductors remain
isolated. Bonding of the two conductors is allowed at the power source only.

Humidifier drain and water supply
For more information about the humidifier, see the documentation developed by the humidifier
manufacturer.
Convenience outlets
The HP POD is prewired for a convenience outlet on the inside of the unit. This circuit is not part of the
power provided by the main switchboard feeding the 3 phase power to the HP POD. To energize this
circuit, you must supply a dedicated single phase, 16-or 20-amp branch circuit from your facility at the
appropriate voltage. Make sure that the branch circuit is connected to the prewired exterior mounted
junction box and that it is wired in accordance with local regulations and codes.
Grounding requirements
The neutrals and equipment grounding conductors for all 3-phase HP POD feeders must remain isolated.
The two conductors can be bonded at the power source only.
Functional and supplementary grounding straps are provided between each rack and HP POD.
IMPORTANT: Before installing the HP POD, consult your local AHJ for applicable codes and
to review site-specific location guidelines. If needed, obtain any necessary permits.
Supported facility connections 18
IMPORTANT: For full protection, you must ground the HP POD, power distribution
components and the water distribution kit to your ground grid system.
IT cable portals
Six 6.35 cm (2 ½-inch) IT cable portals on each side of the HP POD are available for optional Ethernet,
fiber optic, and IT cable configuration. These components are also used for ECS connections and can
support dedicated lines, a customer network, and various other communications service options. You can
install a weatherproof box for termination points over the cable portals on the outside of the HP POD.
Examples of cables that can run into the 6.35 cm (2 ½ inch) portals are as follows:
•
48 Cat-6 cables
•
39 12 strand multi-mode or single-mode fiber optic cables
HP POD security
The HP POD is equipped with standard key lock hardware at each entry door and external panel.
Conduit and junction boxes are provided for customer installed controlled access systems.
Optional controlled access security includes a 12-digit security code keypad and magnetic locks on each
entry door.
HP POD Environmental Control System
The HP POD ECS is a stand-alone system that does not require any connections to existing facility
management infrastructure. You can choose to connect to the facility BMS at an additional cost. BMS
configuration communicates through an Ethernet cable connected to the internal HP POD ECS panel jack
located underneath the IT cable portals. HP POD ECS data can be sent and viewed using a set IP
address.
The HP POD ECS communicates through the standard BMS protocol, which is a data communication
protocol for building automation and control networks.
Supported facility connections 19
The HP POD ECS offers:
•
The ability to monitor the status of water and air temperatures, water pressures, and water flow rates
•
Immediate notification of supported alarm messages
For additional points that can be monitored, see the I/O (Input/Output) Controls Points List.
Fire, safety, and security notifications
Dry contacts are provided to enable the connection between the fire alarm system and the central facility
fire detection system, relay alarm, and trouble conditions at each HP POD.
Your building fire, safety, and security system relays the following HP POD-initiated alarms, which operate
independently of each other.
