INSTALLATION INSTRUCTIONS

Failure to follow these instructions could result in
property damage, personal injury, or death.
Requirements:
•
Electrical terminations must be completed by qualified persons.
•
No special tools or protective equipment is needed to handle this product (specific applications or
surfaces may require protective equipment).
•
Installation temperature range: -60°F (-51°C) to 131°F (55°C).
•
Clearance of 3" (7.5cm) required around vessel during installation.
•
Voltage and frequency must be within +/-10% of the value specified on the product label.
•
If the heater is not grounded then it must be mounted to a grounded surface or a conducting
grounded screen must be placed between the heater and the surface.
Surface Preparation:
Always install your heater on a clean even surface for optimum performance and extended service life.
Debris and residue on the surface can not only damage your heater but may also reduce the
effectiveness of the heater by reducing the heat transfer between the surface and the heater.
•
Remove or avoid contact with sharp edges including rough corners, weld spatter, exposed bolts,
etc.
•
Remove or avoid contact with rust, stickers, or other coverings.
•
Remove oil, moisture, gel and other liquids.
Instructions:
1. Inspect heater prior to each installation (see inspection procedure).
2. Inspect vessel to be heated for any sharp edges, rust, oil, etc.
3. Ensure that there is no combustible material within 12" (30cm) of the surface to be heated.
4. Sensor placement
For proper temperature control, place the thermocouple, RTD, or other sensing device, so that it
touches the edge of the heating blanket.
•
Sensor must be in close proximity to the heater to prevent overheating.
•
If heating blanket is installed on a vertical surface, place sensor directly on lower edge of
heating blanket since heat naturally rises.
•
Sensor should be connected in accordance with instructions provided with temperature
controller.
•
Secure with one strip of aluminum adhesive tape

5. Mounting
Heaters supplied with PSA (Pressure sensitive adhesive):
For PSA Models Only - Installation of heater using factory supplied Pressure Sensitive
Adhesive (PSA):
Peel off the release film [Figure A] and then press the heater onto the surface of the item being
heated using a medium to hard rubber roller [Figure B]. Ensure heating blanket is making intimate
contact with the surface to be heated.
•
The pressure sensitive adhesive will cure when the heating blanket is energized and heat is
generated. PSA generally cures in twenty minutes at 200ºF (93ºC) in a 68ºF (20ºC) ambient
environment. The cure time will vary with temperature of the heating heating blanket and
surrounding ambient conditions. The higher the ambient temperature and set-point of the
heating blanket, the faster the cure time.
•
The heating blanket may require a temporary method of attachment to secure the heater until
the PSA cures. Use a high-temperature adhesive tape (BriskHeat
secure the heater.
•
For larger heaters, press the heater onto the surface as the film is removed.
®
Note: BriskHeat does not recommend allowing pressure sensitive adhesive to cure at
temperatures below 40ºF (4ºC).

Heater without PSA may be mounted with:
•
Factory supplied mechanical fasteners (if provided)
•
Hight temperature adhesive tape
•
Thin layer (<1/8" (3mm)) of RTV
6. Check for any air-gaps between the heater and surface. Air-gaps can reduce heat transfer from the
heater causing excess heat.
