3.3 Pump installation

The SeaStar P/A can be wall-mounted to a bulkhead or transom, or floor-
mounted with the accessory mounting foot (included). Mounting
templates for wall and floor mounting are provided in section 7.
When determining where to mount the pump, consider the following:
• The P/A must be mounted in a dry location.
• The P/A must be mounted within 10° of vertical. Mounting in any other
orientation will result in a poor purge of air from the system, leading to
poor performance and possible safety hazard.
• The pump motor will get hot during heavy use. Do not mount the pump in
an area where fabrics or other flammable materials may contact the motor.
• The P/A will make noise comparable to an autopilot pump; consider this
if installing the pump in a center console, or in an area where you wish to
limit noise.
• The pump motor contains strong magnets that may affect a magnetic
compass. Ensure the power assist is at least 24" (60 cm) from a compass.
• The pump's electronics may be affected by strong magnetic fields. Do
not mount the power assist within 12" (30 cm) of devices that generate
magnetic fields, such as electric motors (e.g. bilge pump).
• The straight fittings installed in the pump may limit where you can place
the pump while respecting the minimum bend radius of the hose. To
mount the pump closer to a bulkhead you can install 90° fittings in place
of the straight fittings. See section 3.3.1.

WARNING!
Failure to correctly mount the P/A within 10° of vertical may lead to excessive
air in the steering system, leading to poor steering performance and/or
the potential loss of steering control, leading to a collision and/or ejection
from the boat leading to property damage, personal injury, and/or death.
