Installation
Requirements
Location
Put the equipment on a flat surface, such as concrete, that is capable of supporting the weight of the pump and
thick enough to resist vibration. The feet on the frame can be adjusted to level the pump.
Make sure that there is a minimum clearance of 91 cm (36 inches) on all sides of the equipment to permit air
movement for efficient cooling and room for maintenance and repair.
Temperature
Ambient temperature has an effect on cooling. Supplementary cooling is usually necessary for a pump confined
to a small, high-temperature space.
For temperature requirements, refer to the Pump specifications, which begin on page 173.
Electrical power
The motor size determines the full load amperes, the overload settings, and the wire sizes. Refer to the technical
drawings for more information.
The electrical power requirements are on the data plate on the rear of the pump and on the inside of the
electrical enclosure door.
WARNING
Some locations can be hazardous if the atmosphere contains gas, vapors, or dust in explosive
quantities. Refer to requirements from the National Electric Code (NEC), the International
Electrotechnical Commission (IEC), and the Occupational Safety and Health Administration
(OSHA), as well as local codes for detailed information about environmental criteria.
CAUTION
When work must be done in confined spaces with limited access, the access must not be blocked
by ventilation ducts, hoses, pipes, or other equipment.
Do not install this equipment in an environment where the temperature is below freezing. Freezing
can cause severe damage to low-pressure and high-pressure water parts.
Equipment installed in a hot location can require a larger external air cooler. Contact the OEM or a
Hypertherm Technical Service Associate for assistance.
DANGER
Dangerous voltage
To reduce the risk of serious injuries or death, wear approved protection and follow safety
recommendations when working with electricity.
WARNING
Make sure that a line disconnect switch for incoming electrical power is installed near the power
supply to serve as a supply-voltage disconnecting or isolating device.
Make sure that the primary feed protection device (circuit breaker or fuse) is sized to handle inrush
and steady-state current. Use a motor-start circuit breaker or an equivalent if time-delayed
high-inrush fuses are not permitted by local or national codes.
