connections. Current carrying parts of the controller shall be not less than 12 in. (305 mm) above the floor level.
Working clearances around the 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).
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 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 fire pump controller shall meet the latest edition of NFPA
20, NFPA 70 National Electrical Code Article 695 or C22.1 Canadian Electrical Code, Section 32-200 or other local
codes. Electrical wiring shall be typically sized to carry at least 125% of the full load current (FLC or FLA) of the fire
pump motor.
Electrical Connections
Electrical Power 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. The electrician is responsible for adequate protection of the fire pump controller internal
components against debris or drilling chips. Failure to do so may cause injuries to personnel, damage the controller
and will void warranty.
Other Connections - (Alarm etc.):
A qualified technician must make connections. Only watertight hub fittings shall be used when entering the cabinet.
The technician is responsible for adequate protection of the fire pump controller internal components against debris
or drilling chips. Failure to do so may cause injuries to personnel, damage the controller and will void warranty.
Energy Consumption
Standby power: 10W
Sizing
Incoming power terminals on the controller are suitable to accept wire based on that selection with insulation not
