HK Instruments MM Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments MM series liquid col-
umn manometer. The MM series is intended for use in commercial
environments for air and non-corrosive gases. The MM series is de-
signed with overpressure reservoir to protect the manometer liquid
from leaking into the duct during overpressure.
The MM series includes a field adjustable zero point calibration and
pressure limit stickers. The MM series is available with optional level
bubble.
APPLICATIONS
MM series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• pressure and flow monitoring
