RECEIVING & UNPACKING EQUIPMENT
1. Check packing slip to ensure ALL material has been delivered.
2. All material shortages are to be reported to Walter Meier (NORTEC) within 48 hours from receipt of goods. Walter Meier (NORTEC) assumes no responsibility for any material shortages beyond this period.
3. Inspect shipping boxes for damage and note on shipping waybill accordingly.
4. After unpacking, inspect equipment for damage and if damage is found, notify the shipper promptly.
5. All NORTEC products are shipped on an F.O.B. factory basis. Any and all damage, breakage or loss claims are to be made directly to the shipping company.
6. Each distributor is provided with: installation manual, one hose cuff, and two hose clamps.
PRE-INSTALLATION CHECK
1. Ensure the total capacity of the humidifier is not higher than the allowable maximum steam capacity of the distributors used.

GUIDELINES
1. Nortec steam hose should only be used on short steam runs below 10 feet.
2. Ensure that no condensate produced in the steam line will remain trapped. Steam naturally flows upward and condensate naturally flows downward.
3. See material recommended for use in the chart below. To eliminate the metal corrosion, Nortec does not recommend the use of steel piping.

Please note that options shown in a bold-italic font requires that reducers be used at both ends. These extra large sizes are to allow for better condensation removal in long steam runs. These sizes will not permit you to use hose coupling to connect your self to either humidifier or distributors.

CONDENSATE RETURN GUIDELINES FOR
MAIN STEAM LINES
1. Use vertical condensate leg of distributor only. Do not over-tighten clamp.
2. Drip stations on steam mains must be located at all low points in the system, at each elevation change and or directional change.
6. Vertical drop of the drip station should be
1.5 times the diameter of the steam main but no less then 12”.
7. At the bottom of this drip station is where the “p-trap” is installed. It is to be 2” larger then the duct static duct pressure.
8. All distributors must be individually trapped.
3. Horizontal runs of steam must have a 2” rise per foot (10º) when flow is going upwards from drip station and the steam run is to fall ½” per foot (2º) when flow is going downwards to drip station.
4. In a horizontal run of the steam main, drip stations must be located at regular intervals of 20 feet.
5. The drip station itself is a section of piping connected to the bottom of the main. A full size tee must be used to create a drip station to allow the condensate to fall in the drip station.

WARNING:
·
These installation guidelines apply for duct velocities under 2000 ft/min (610 m/min), please consult factory for higher velocities.
·
Please make sure no obstacles (elbow, filter, or diffuser) are located after the distributor in the direction of the airflow closer than the absorption distance calculated for your application.
·
Unless you know the exact absorption distance required for the steam absorption into the air stream, the distributor should be located at least 8-10 ft (2-3 m) away from any obstacle it may condense on (elbow, diffuser, filter, etc.).
