Damage to the appliance and the environment
Excessive heat from soldering on copper pipes near the
AQE may cause damage.
 All plumbing work must comply with national and appli-
cable state and local plumbing codes.
 A pressure reducing valve must be installed if the cold water
supply pressure exceeds 150 PSI (10 bar).
 Make certain that the cold water supply line has been
fl ushed to remove any scale and dirt.
 Install isolating valve in cold water line as shown in illustra-
tion "Mounting the appliance". This allows the appliance to
be isolated for maintenance purposes.
 Cold water connection (inlet) is on the right side of the ap-
pliance, hot water connection (outlet) is on the left side of
appliance.
 Tankless water heaters such as the AQE are not required to
be equipped with a Pressure and Temperature Relief Valve
(P&T). If the local inspector will not pass the installation
without a P&T, it should be installed on the hot water outlet
side of appliance.
 The appliance is designed for connection to copper tub-
ing, PEX tubing or a braided stainless steel hose with a ½"
NPT female tapered thread. If soldering near the appliance
is necessary, please direct the fl ame away from the plastic
housing of the appliance in order to avoid damage.
 When all plumbing work is completed, check for leaks and
take corrective action before proceeding.
6. Electrical connection
DANGER Electrocution
Carry out all electrical connection and installation
work in accordance with relevant regulations.
DANGER Electrocution
Only use a permanent connection to the power sup-
ply. The appliance must be able to be separated from
the power supply by an isolator that disconnects all
poles with at least 3 mm contact separation.
Damage to the appliance and the environment
!
Observe the type plate. The specified voltage must
match the mains voltage.

DANGER Electrocution
Before beginning any work on the electric installati-
on, be sure that main breaker panel switch is „off " to
avoid any danger of electric shock. All mounting and
plumbing must be completed before proceeding with
electrical hook-up. Where required by local, state or
national electrical codes the circuit should be equip-
ped with a „ground fault interrupter".
DANGER Electrocution
As with any electric appliance, failure to electrically
ground appliance may result in serious injury or death.
 The appliance should be connected to a properly grounded
dedicated branch circuit of proper voltage rating. In installa-
tions with several appliances, each appliance requires an
independent circuit. Please refer to the technical data table
for the correct wire and circuit breaker size.
 The wire must be fed through the rubber seal located be-
tween the hot and cold water connections. Then feed wires
through strain relief clamp and tighten clamp down on wire.
The „live" wires must be connected to the slots on the ter-
minal block marked L and L (L and N). The ground wire must
be connected to slot marked with the ground symbol. Strain
relief clamp with screws and rubber seal are provided.
6.1 AQE 8/10 - Appliance with output power op-
tions
For the AQE 8/10 instantaneous water heater, the output power
is adjustable in 2 stages. In its delivered condition the appliance
is set to 7.2 kW @ 240 V.
