Figure 1. Mounting Dimensions - Honeywell EC-FX-NH3 Instruction And Installation Manual

Figure 1. Mounting Dimensions

• Sensor must be mounted vertically.
• Never mount flat on a ceiling.
• Enter enclosure only through existing hole in bottom.
• Always make a drip loop in the conduit (see Figure 1).
Blast Freezers: Never mount sensor above the coil. The ideal location,
when possible, is below the bottom of the coil. Try to put in return air and
protect the unit from being damaged by product loading and unloading.
Keep it away from warm, moist air during defrost. Usually four or five feet off
the ground is the best location.
Penthouses:
• Multi-Coil (defrost one coil at a time): In this case the best location is
usually in the center of the penthouse four or five feet above the
grate.
Single Coil (or when all coils defrost at the same time): In this case
•
high moisture conditions can occur and the sensor should be
mounted one foot above the grate.
Engine Rooms: The sensor should be mounted in a cool part of the room, if
possible. Keep the sensor away from hot air exhausting from electric motors
or other machinery. Usually the best location is four or five feet above the
floor in a location where the room exhaust fan will move air across the sensor
from the potential leak source.
