Maintenance
Modifications should not be made to this
product. Replacement parts, including
immersion heaters, should be purchased from
Ideal Boilers, or agents approved by them.
Unvented hot water storage vessels need
regular routine checks, and these are detailed
below. It is for this reason that this manual must
always be left with the Ideal HP.
It is essential that these checks be carried out
at the time of annual heat pump maintenance
by a qualified installer:
1. Manually open the relief valves in turn, and
check that water is discharged from the
valves and runs freely through the tundish
and out at the discharge point. Ensure that
the valves re-seat satisfactorily. (Note - the
water may be very hot).
2. It is important to check that the discharge
pipework is carrying the water away
adequately. Check for blockages etc. if it is
not.
3. Turn the mains water off and remove and
clean the strainer element in the Pressure
Reducing Valve.
4. Check the charge pressure in the expansion
vessel and repressurise if required
5. Re-fill the system and ensure that all relief
valves have re-seated.
6. The Benchmark Service Record should be
updated at each service.
7. Check the water pressure downstream of the
combination valve is 3 bar in static condition.
8. Check and if necessary, descale the heat
exchanger in hard water areas ie. above
200ppm (mg/l).
Note:
The cylinder is factory fitted with a lift up
temperature & pressure relief valve that must
not be used for any other purpose or removed.
The cylinder is factory fitted with immersion
heaters with thermal cut outs. Immersions
without thermal cut outs must not be fitted.

All cylinders are manufactured in accordance with the requirements of BS EN 12897
The tundish must be positioned so that it is visible to the occupant and is away from
electrical devices.
Components supplied with Ideal HP:
• Cold water inlet PRV combination valve/expansion relief
• Lift up pressure and temperature relief valve
• Control thermostat
• Energy cut-out thermostat
• Energy cut-out motorised valve (indirects only)
• Tundish
• 3kW Immersion heater including control and cut out thermostats
• Drain elbow and 90 degree elbow
• Expansion vessel/mounting bracket
• Technical/user product literature
In any situation where the volume of heated pipework (eg. secondary circulation
pipes or manifold pipework for multiple units) exceeds 10 litres, then an
additional expansion vessel must be fitted to accommodate the extra expansion
volume.
Handling Before Installation
Ideal HP must be handled with care and stored the correct way up in a dry place.
Any manual handling/lifting operations will need to comply with the requirements
of the Manual Handling Operations Regulations issued by the H.S.E. The appliance
can be moved using a sack truck on the rear face although care should be taken and
the route should be even. In apartment buildings containing a number of storeys we
would recommend that the appliances are moved vertically in a mechanical lift. If it is
proposed to use a crane, expert advice should be obtained regarding the need for
slings, lifting beams etc.
A specific manual handling assessment is shown in Appendix B at the rear of this
manual.
The Environment
This product has been manufactured using many recyclable materials, including the
approved HCFC/CFC free polyurethane foam insulation. At the end of its useful life, it
should be disposed of at a Local Authority Recycling Centre, to maximise the products
full environmental benefits.
