LIFTING
Always exercise extreme caution when lifting to avoid damage, lift from underneath on a pallet or base if
fitted
Avoid lifting from any of the pipework, controller, or valves
WATER CONNECTIONS
Do not weld near to or on the heat exchanger or associated components.
Use two wrenches when attaching unions to the domestic water circuit threaded stub connections. One wrench to be used to tighten
the union & the other to prevent the stub end from rotating
–
this avoids damage to the gasket inside the unit that seals against the
back on the stub connection. Use a none hardening thread sealant for best results. Threads are BS21
–
taper, male. It is necessary
to support the secondary pump and the pipe work as the heat exchanger connections are not designed to accept any weight being
imposed upon them.
To avoid damage to the unit, to prevent failure and to ease maintenance, we recommend the following:
•
Pipe-work - fully support to avoid weight/forces acting upon the unit / connections.
•
The fitting of flexible couplings if the pipe work is subject to vibration.
•
The pipe work is completely flushed before attaching to exchanger. The exchanger acts as an effective filter and will
become blocked if pipe-work debris can enter the plate pack.
•
The fitting of suitable vents, isolation valves & drains. To allow servicing of the package without complete system draining
appropriate isolation valves should be fitted.
•
The fitting of non-return valves where appropriate
•
The fitting of suitable sized pressure relief valves in the pipe work on both circuits (essential safety requirement).
The LOKE must be installed as per the schematics
failure to include all necessary valves etc. Will
invalidate the warranty and could lead to a dangerous situation on site.
UN-VENTED SYSTEM ARRANGEMENT
If the LOKE is to be used in an unvented arrangement, the system should follow the guidance given in
BS6700
and must comply
with
The Building Regulations: Part G3 in England and Wales, P5 in Northern Ireland and P3 in Scotland.
A kit of components
that have been suitably sized for the unvented or boosted operation of the appliance is available from Lochinvar Limited. For further
information, see below.
