Maintenance - Johnson Pump Viking Power 16 Handbuch

Installation and maintenance
Installation
Locate the pump in a dry location.
• If the pump is mounted vertically, the
motor must be above the pump house
• Mark screw positions and drill pilot
holes.
• Mount the pump using stainless steel
screws with the enclosed stainless steel
washer. Make sure that the plastic spac-
ers are in their correct position. Take
care not to over compress the vibration
dampening rubber feet. (The screws are
too tight if the pump house is in contact
with the surface.)
• Reinforced flexible tubing is recommended.
• Use stainless steel hose clamps to secure
tubing to quick disconnect fittings and
other hose barbs in the system.
Pump configuration
The pump can be configured in three dif-
ferent ways:
• With the motor to the left
• With the motor to the right
• With the motor straight up
The set-up can easily be changed by follow-
ing this procedure:
1. Unscrew the six screws holding the pump
to the steel foot
2. Set the pump with the motor facing in the
desired direction
3. Fasten the six screws
Electrical installation
The pump must be installed according to
ISO 10133 (Small craft – Electrical system
– Extra low voltage DC installation for con-
tinuous current). Note: The fuse must be ig-
nition protected.
The motor is equipped with built in thermal
protection to prevent the motor from over-
heating. The protection is automatically re-
stored when the motor is cooled.
If the pump is connected with separate
earth lead, this should be yellow/green and
connected to the motor base. See the wiring
table (next page) for correct installation.
Negative wire must be black. Choose wire
size in accordance with total wire lenght
(see table next page). The wire connections
must be sealed with a marine sealant.
Note: Before installation with electrical
control systems, check that equipment to
be used is of sufficient rated capacity to ac-
cept amperage draw of motor. Low voltage
will cause motor to overheat.

Maintenance

The pumps valves inside the pump house
should be regularly cleared from debris to
prevent reduced performance.
This is done by unscrewing the house clamp
and opening the house. Make sure pump is
disconnected from the power supply.

* The wire length is the total distance from the
battery to the pump and back to the battery. It is
recommended to use a relay with a light wire from
the main cable to shorten the main leaders.
Self-priming
Pump is self-priming up to 3 m/10 feet.
Dry running
The pump can be run dry without any
harm. It will however unnecessary reduce
your battery power.
