Working clearances around controller shall comply with NFPA 70, National Electrical Code, Article 110 or C22.1,
Canadian Electrical Code, Article 26.302 or other local codes.
The controller is suitable for use in locations subject to a moderate degree of moisture, such as a damp basement.
The pump room ambient temperature shall be between 39°F (4°C) and 104°F (40°C) (If a temperature option is
included, see the rating label for maximum temperature).
The standard controller enclosure is rated NEMA 2. It is the installer's responsibility to insure that either the
standard enclosure meets the ambient conditions or that an enclosure with an appropriate rating has been
provided. Controllers must be installed inside a building and they are not designed for outside environment. The
paint color may change if the controller is exposed to ultraviolet rays for a long period of time.
Mounting
The fire pump controller shall be mounted in a substantial manner on a single incombustible supporting structure.
Wall mounted controllers shall be attached to the structure or wall using all four (4) mounting ears provided on the
controller with hardware designed to support the weight of the controller at a height not less than 12 in. (305 mm)
above floor level. Floor mounted controllers shall be attached to the floor using all holes provided on the mounting
feet with hardware designed to support the weight of the controller. The mounting feet provide the necessary 12 in.
(305 mm) clearance for current carrying parts. For seismic applications, the mounting arrangement should be rigid
wall and base only. The structural engineer of record on the project shall be responsible for anchorage details.
Storage
If the controller is not installed and energized immediately, Tornatech recommend following the instructions from the
chapter 3 of the NEMA ICS 15 standard.
Wiring and Connections
Water Connections
The controller must be connected to the pipe system according to the latest edition of NFPA20 and also to a drain
pipe. The water connections are on the left side of the controller. The connection to the system pressure is a Male
½ NPT. If a drain is present, the connection to the drain is a tapered connection for plastic tubing.
Electrical Wiring
The electrical wiring between the power source and the diesel engine fire pump controller shall meet the NFPA 20,
Chapter 12.3.5.1, 12.3.5.2 and 12.2.5.3, NFPA 70 National Electrical Code Article 695 or C22.1 Canadian Electrical
Code, Section 32-200 or other local codes.
Electrical Connections
A licensed electrician must supervise the electrical connections. The dimension drawings show the area suitable for
incoming power and motor connections. No other location shall be used. Only watertight hub fittings shall be used
when entering the cabinet to preserve the NEMA rating of the cabinet. The installer is responsible for adequate
protection of the fire pump controller components against metallic debris or drilling chips. Failure to do so may
cause injuries to personnel, damage the controller and subsequently void warranty.
