INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS

Valve Specifications:

1) The Haws Freeze Protection Valve monitors water temperature. When water temperature cools down
to 36⁰F or below, the thermostat connects inlet to drain and valve starts bleeding. When water
temperature rises to 42⁰F or above, valve will close completely.

2). The Freeze Protection Valve has 1/2 NPT (F) inlet, 1/2 NPT (F) outlet (in-line installation only), 1/2”
NPT (F) drain connections.

Do not install the valve in-line for drench showers! It does not have the capacity to provide the
necessary flow.

3). Minimum/Maximum operating pressure: 20 PSI/125 PSI.

Minimum / Maximum ambient temperature: 0°F /130°F.
Maximum water temperature 165°F.

‐ Dead-Leg application: valve can be used for eyewash, shower, or combination units.
‐ Contamination resistant seat design for drip free closing.
‐ Paraffin thermostat for industry leading response time and reliability.

IMPORTANT

To ensure proper operation of the valve, it is essential that:

‐ Haws Freeze Protection Valve must be located next to the eyewash for eyewash or combination

units.

‐ Freeze Protection bleed valve must be located at the dead-leg of drain shower only.
‐ In-line application: use to feed eyewash only.
‐ Dead-Leg application: valve can be used for eyewash, shower, or combination units.

Failure to comply with installation instructions could result in ineffective freeze
protection, or dangerous flow restriction to showers.
