WATER REQUIREMENTS
3.1 All 7kW, 9kW and 12kW heaters have an operational pressure range of 0.1Mpa
(1bar) to 0.7Mpa (7.0bar). Both inlet and outlet connections are suitable for
15mm diameter copper pipe.
3.2 The tee piece and expansion relief valve must be situated where shown
(see gure3. item D) and the relief valve discharge port plumbed via an air
break (tundish) to a safe, visible place where there is no risk to persons.
3.3 The discharge pipe must fall continuously from the valve outlets and be
unobstructed.
3.4 An isolating stop valve MUST be incorporated to the main water supply to
comply with Water Regulations.
3.5 To obtain optimum performance a ow restrictor (isolating ball valve) must
be tted where shown (see gure 3. item B). This provides temperature control
during commissioning (see 5.3 SETTING FLOW RATE).

ELECTRICAL REQUIREMENTS
3.6 This appliance must be earthed.
3.7 The installation, supply cable and circuit protection must conform to the
latest BS7671 ‘Requirements for electrical installations’ (IEE Wiring
Regulations).
3.8 The PowerPack heater must only be connected to a 230/240V ac supply.
3.9 Before making any electrical connections within the installation, make sure
that no terminal is live. If in doubt, SWITCH OFF the whole installation at the
consumer unit or switch fuse (where tted).
3.10 The PowerPack heater must be connected to its own independent electrical
circuit.
3.11 Check that your consumer unit (main fuse box):
1. has a main switch rating of 80A or above.
2. has a spare fuse way which will take the fuse/mcb you need to
t - see (Figure. 4). If so, you can wire the PowerPack direct to the spare fuse of
your consumer unit via a suitably rated isolating switch- (see Figure.4). Note
that not all consumer units will accept a 35/40/45A sized fuse.
3.12 If point 3.11, 1 and 2 are not achievable, the installation is not straight forward,
since it could involve installing a new consumer unit to serve the whole house
or just the PowerPack. You will need to call in your Regional Electricity
Company to check the circuit and make the connections to the meter or service
connector block. They should also check the earth bonding of items in the
vicinity.
3.13 Aresidual current device (rcd), formerly known as an earth leakage circuit
breaker (elcb), with a tripping current of 30mA must be incorporated in the
circuit.
3.14 A double-pole isolating switch rated at (30A for 7kW, 40A for 9kW, and
50A for 12kW), with a contact separation of at least 3mm in each pole, must be
incorporated in the circuit. This must have a mechanical indicator showing when
the contacts are open. An indicator lamp alone is not sufcient. Only cord
operated switches can be tted in bathrooms.

PREPARATION
4.1 Remove the xing screw which holds the front cover onto the back plate of the
PowerPack heater. Carefully remove the cover.
4.2 The unit must be mounted on a at surface, which covers the full width and
length of the back plate. It is important that the wall surface is at otherwise
difculty may be encountered when tting the cover.
4.3 DO NOT t the PowerPack to the wall and tile up to the case. It must be tted
on to a nished at and even wall surface. This allows removal for servicing.
CABLE ENTRY
4.4 Cable entry can be from the rear (see Figure 5) or from the bottom.
When opting for bottom entry make cut-out to suit cable before tting back
plate to the wall.
4.5 Fix the PowerPack heater loosely to the wall. The wallplugs provided are
suitable for most brick walls (use a 6.5mm diameter masonry drill), but if your
wall is plasterboard or soft building block, you should use special wallplugs and
an appropriate drill, obtainable from most hardware stores.
PLUMBING
4.6 Decide where to connect to the water mains for your feed to the PowerPack.
Ensure that the pipe you have selected is not a gas pipe or a hot water pipe or
from a cold water storage tank.
4.7 Cut the necessary pipe work to length, assemble and offer up to the installation
before making any soldered joints. Ensure that the pipe is the correct length, as
shortening it can be difcult once joints have been made.
4.8 An isolating stop valve MUST be incorporated to the main water supply to
comply with Water Regulations
4.9 Assemble the installation before making any soldered joints. DO NOT use
jointing compounds on any pipe ttings for the installation.
4.10 Remove the unit before soldering the connections.
4.11 It is essential to ush the pipe in order to clear debris, particles of solder and
swarf.
4.12 Turn the water off after ushing using the isolating stop valve.
4.13 Connect the cold water supply pipe to the inlet of the PowerPack, this is a 1/2”
BSP connection.
4.14 Fit top and bottom screws and secure the back plate to the wall ensuring that it
is level.
4.15 Connect all other components as per Figure 3.
4.16 Turn the isolating stop valve on slowly and check for leaks in all pipe work,
rectify as necessary.
4.17 Turn off the isolating stop valve.
4.18 Place the cover onto the back plate.
4.19 Secure the cover to back plate using screw provided.

5.0 COMMISSIONING
5.1 Once installed, the heater will operate automatically when the outlet valve is
opened. The valve must be opened fully to obtain the set ow/temperature.
Reduced ow at the outlet will result in hotter water being delivered.
5.2 On closing the outlet valve the heating element will automatically shut down
provided this tap has been turned off by the user.
SETTING FLOW RATE
5.3 To set the ow rate, make sure the water and power are turned off. Open the
outlet valve fully (see gure 3) and close the ow restrictor. Open the stop
valve and open the ow restrictor (allowing all air to be purged). When all air
is purged switch the power on, wait for a few seconds while the water is heated
and adjust ow restrictor to suit the required temperature. Remember the outlet
valve is fully opened at this point so the required temperature may need further
adjustment.
5.4 It is important to note when setting the ow rate/temperature that 48°C is the
point at which the average person cannot hold his or her hand under a stream of
water. Under most circumstances the water temperature need not be higher than
this and it is recommended that this temperature is not exceeded for normal
use.
5.5 These heaters will supply only one outlet at any time and must be controlled by
a single outlet valve. DO NOT USE WITH MIXER VALVES.
