INSTRUCTION FOR INSTALLATION, USE AND MAINTENANCE
SRM pumps are electric motor driven centrifugal pumps, used mainly for hydro-massage systems of bath tubs
and spa bath pools.
Other applications are possible, but the pumped liquids temperature should not exceed 35°C.-
SAFETY MEASURES
ATTENTION:
The pipe system connected with the pump must be supported otherwise the pump casing might get
damaged and damages caused by not existing pipe supports are not guarantee covered.
PLACE FOR INSTALLATION
The pump must be installed as near as possible to the bath tub or spa bath and lower than the water level. The suction
pipe must be short and straight, curves and connections cause pressure losses with negative effects to the pumps
performance.
The pump must be fixed on a solid basement in order to guarantee a fixed position without vibrations. Further on there
must be the possibility to service and control the pump.
The pump must be positioned in a dry or ventilated place and in a way to avoid flooding.
CONNECTION OF PIPE SYSTEM
The suction and the pressure pipe system must be supported as near as possible to the pump in order to avoid forces like
traction, compression or weight on the pumps casing, which might damage it. As a principle the pipe work must start at the
pump side and go to the system, above mentioned damaging forces can be avoided only in this way.
It is recommended to use pipes with bigger diameters for the suction and the pressure side in case of distances between
the pump and the tub longer than one meter . In this way pressure losses will be reduced.
The suction pipe's diameter must never be smaller than the pumps suction side.
SUCTION PIPE
The suction pipe must be
1.
perfectly tight
2.
provided with an interception valve
connection nut in case of use near
a spa bath or pool.
POWER SUPPLY NET CONNECTION
Before connecting the pump to the electrical net supply, the correspondence of pump's label specifications with those of
the net supply must be checked. The net's exercise tension and the frequency must be the same as those written on the
pump's label. If there are any doubts ask the supplier of the pump.
The second step is the right net connection as shown for single phase pumps with scheme 'Sch.1' .
ATTENTION
: The pump's motor must be grounded.
The use of pumps near swimming pools or garden ponds is allowed when those are built in compliance with
EN 60335 / 2 /41 Please get necessary information from Your electrician.
It is compulsory to install a live saving differential switch with 30mA and a one pole interruption with an opening of minimum
3mm.
In case of pumps with three phase motors an overload switch suitable to the motor's nominal specifications must be
installed.
THE PUMPS MAINTENANCE
ATTENTION
: Before starting any maintenance job on the pump or the system the electric power supply must be cut off
(e.g.: unplug it from the power socket) and make sure it cannot restart on its own.
SRM centrifugal pumps require a minimum of maintenance except regular cleaning like any other electric motor driven
domestic appliance.
The mechanical seal between the electric motor and the pump casing might be subject to consumption, therefore its state
must be verified all two years and in case of high consumption changed.
Our dealer will help You showing You to the nearest JTC-after sales service.
ATTENTION:
Repairs made by people not authorised by JTC will automatically interrupt all warranty rights otherwise
granted by JTC. It is recommended to use only original JTC spare parts.
WARRANTY
JTC grants accurate controls and tests of all pump components as well as the pump unit, therefore warranty claims can
be accepted within two years from purchase date. Only ware parts like mechanical seals or ball bearings will be excluded.
In case of warranty claims JTC will repair or change parts if the claim is acceptable.
