Johnson Pump FlowMaster WPS 5.0 Manual De Instrucciones página 9

Flow Master Water Pressure Systems 5.0
mounted to dc motor 12/24 V
Please follow all instructions before attempting an installation.
Warning!
The five chamber Flowmaster series pumps
are very powerful and as a result may draw
more current (Amps) than the pump(s)
they replace. It is very important that any
power supply, fuses/circuitbreakers, wiring,
switches, connectors, or controllers that
are used to supply 1VDC to the pump are
adequately sized. Inadequetly sized com-
ponents may overheat, causing an electri-
cal fire. When installing the pump, positive
voltage (+1VDC) must be connected to
the Flowmaster's red fused leadwire. Re-
versing polarity will instantly blow the fuse
and may permanently damage the control-
ler. If you are uncertain with respect to any
of this information, Johnson Pump highly
recommends that a qualified technician
perform your installation and determine
the existing polarity of your current wiring.
Important Safety Tips:
1. After extended operation, or if malfunc-
tioning, metal surfaces of the pump may
become hot and cause burns if touched.
If this occurs, disconnect electrical pow-
er and wait 30 minutes before touching
pump.
. Never mount the pump where the sur-
face temperature of the motor or the
controller (95°C/00°F maximum) may
cause ignition of the surrounding mate-
rials.
3. Do not wrap the pump with an insu-
lating material or enclose it so tightly
that air circulation around the pump is
prevented. The pump will generate ap-
proximately the same amount of heat as
a 75 watt lightbulb.
4. The pump should be mounted in a dry
location away from any heat source(s).
5. Pumphead materials are designed for
use with potable water only and should
never be used with petroleum products.
6. The pump is equipped with a pressure
sensing demand switch which controls
the maximum operating pressure as set
at the factory. Never subject the pump
to pressures above 80 PSI maximum.
7. Always consider electrical shock haz-
ards when working with and handling
electrical equipment. If uncertain in
your abilities, please consult an electri-
cian.
8. The Flowmaster is equipped with an au-
tomatically resetting thermal protector.
If a pump is not running, it may restart
at any time.
9. For both 1V/4V models use the ap-
propriate fuse for the appropriate volt-
age.
10. It is necessary to use a screen filter be-
tween the water holding tank and the
pump to prevent debris from entering
the pump. Particulate matter may cause
the valves inside the pump to stick open.
This filter needs to be cleaned on a regu-
lar basis, or it will restrict water to the
pump.
11. If water is not drained from the system
during freezing temperatures, damage
to the pump and the plumbing is like-
ly: a) Drain the water holding tank. b)
Open all faucets and run the pump to
expel all water c) Disconnect inlet and
outlet fittings and run pump to remove
residual water from the pump. d) Leave
fittings disconnected from pump.
Installer Qualifications: If you intend to in-
stall the Flowmaster without professional
assistance, you should clearly be "handy-
man" competent enough to do simple low
voltage electrical wiring, crimp connectors,
obtain voltage measurements, understand
polarity as well as schematics which illus-
trate relay connections. Additionally, you
should be comfortable with water system
plumbing, installing hose clamps, using Tef-
lon (Teflon is a trademarks or registered
trademarks of E.I. du Pont de Nemours and
Company) tape, and removing/re-tighten-
ing compression fittings.
