Using the Powerstream Pro

Warning

Do not use the unit if you think it may be frozen,
as this could result in serious damage to the unit.
Wait until you are sure-it has completely thawed
out before you switch it on.

Sink

• Check that the power is switched on

at the circuit breaker panel.

• Turn on the hot tap FULLY If you do

not turn the tap full on, you will find that
the temperature of the water may vary
The hot water can be adjusted by
altering the temperature dial and
correctly setting the flow rate. Refer to
appendix on page 10 - correct flow
vs. temperature,

• If the unit has been used recently, run

the water through for a few seconds to
let the temperature settle down. You may
initially get a short burst of very hot water
from the unit,

• It a second tap connected to the unit

is also turned on, the hot water will be
shared between the two, therefore the
flow and/or the temperature of the water
will decrease.

Installing the Powerstream Pro

where there is a chance of freezing.

Deciding the wiring route

• You have a choice of whether to feed

the electric cable through the side or
through the back of the unit,

• If it is gong to be through the side of the

unit, cut out the plastic lug to expose the
rubber sleeve (diagram 2.)

Plumbing in the unit

Fitting the pipes

• The unit should be connected directly to

the main cold water supply and not to pre­heated water. The unit should be installed
with service valves on both the inlet and
outlet.

• We recommend that you use ½"

• If it is going through the back of the unit, cut

through the grommet on the backplate with a
sharp knife. Make sure that you do not remove
the grommet from the backplate (diagram 3.)
Feed the cable through the grommet before
you mount the unit to the wall. If you are
using an approved cable fitting, remove the
grommet.

copper or high pressure flex

• Use Teflon tape for sealing pipe threads.

Do NOT use pipe dope.

sink, a similarly flow restricted
aerator should be used at each tap.
If not, the highest flowing outlet will
take all the water under dual usage.

before you wire it, flush it with water to
remove any debris or loose particles.
Failure to do so may make the unit
inoperable.

Connecting the unit to the pipes

• The inlet and outlet are clearly marked

on the unit. They each have a ½" NPT
connector.

• Install a ball valve in the cold water line.

This valve can be used to turn off the
water supply to the unit if it needs
servicing, or to reduce the water flow if it
is too high.

Mounting on the wall

• Undo the retaining screws on the cover

and take the cover of the unit. Hold the
backdate in position against the wall while
you mark the four mounting holes.

• Drill the holes and secure the unit to the

wall using the four no. 8 wood screws
supplied

WARNING - IMPORTANT
Do not install a non-return check valve

within 6 feet of the inlet.

• If the unit is to supply a sink, we

recommend that you use aerators, which
you can get from your local
distributor/dealer.

• As a condition of installing this product in

the Commonwealth of Massachusetts a
pressure relief valve must be installed on the
cold water side by a licensed plumber. MGL 42
Section 19.
