IMPORTANT: If your water is out of range, consult a water quality expert.
IMPORTANT: You must provide a humidification water supply isolation valve that is external to the HP POD 40c G2.
In addition to the previous requirements, observe the following requirements and recommendations:
•Do not treat the water with softeners. Softeners can produce foam, which affects the operation of the unit.
•Do not use well water, industrial water, water from cooling circuits, or water contaminated by any chemicals or bacteria.
•Do not add potential irritants to the water, such as disinfectants or
•The manufacturer recommends installing an

Chilled water supply
The following are the water quality requirements and specifications:
•
•The temperature of the chilled water supplied to the HP POD 40c G2 must be 12ºC to 24ºC (55ºF to 75ºF).
CAUTION: Freezing water can cause a blockage and damage to the unit. In outside locations that are 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 40c G2 must be
