Assembly Instructions
Follow these instructions to ensure that the units are
assembled safely and effectively:
◊ The heat-exchanger must be connected in such a
way that vibrations from the unit may not be trans-
ferred to the piping systems or vice-versa.
◊ Before connecting the unit to an existing warm water
heating system, the boiler and pump must be
checked for adequate capacity.
◊ For maintenance and repairs, we recommend at-
taching a repair switch close to the unit.
◊ After all attachment screws have been tightened
evenly, the fan is to be checked to ensure that it is
running smoothly.
◊ The permissible assembly heights must be ob-
served.
The minimum permissible distances from the floor to
the lower edge of the unit can be found in the table
in the section on unit assembly.

◊ The units may only be attached to sturdy construc-
tions or ceilings made of materials with adequate
bearing capacity.
◊ The units must be attached with sturdy wall mounts
that are fastened to the unit.
◊ Assembly, connection of the heating medium, con-
nection of the electrical system and maintenance
may only be performed by trained and authorised
personnel.
◊ The units may not be set up, assembled or operated
in surroundings susceptible to fire or explosions.
◊ The units must be set up outside of high-traffic
zones, e.g. also cranes.
A safety zone of 1 m must be maintained.
◊ The units may only be operated when mounted.
◊ Safety components such as, for example, protective
grilles, may not be disassembled or taken out of op-
eration.
◊ The units may only be used for their intended pur-
pose within the specified operating ranges and with
approved transport media.
See type plate.
◊ The air intake grille must always be kept free of dirt
and loose objects; the unit outlets may not be
blocked.
◊ Never insert foreign objects into the unit.
◊ The units may not be exposed to a direct stream of

Connection to the heating system
Before connecting to the customer heating system, the
heating and pump capacity must be checked to ensure
that they meet the technical requirements of the respec-
tive unit.
The REMKO PWW unit should be connected via shut-
off valve, automatic dehumidifier and screw attach-
ments in the supply and return lines.
Draining in case of frost
It is not possible to statically drain the heat-exchanger
completely. The heat-exchanger can only be completely
drained when compressed air is used.

Connecting the units
REMKO PWW 5000 models are equipped with axial
fans that have external rotary current motors for a volt-
age of 400 V / 3~ / 50 Hz. Switching the two speeds of
the rotary current motor is done with a Y / ∆switch.
Integrated thermal contacts protect the motor.
They switch off the fan motor at a winding temperature
of 130 °C in connection with a suitable switching device
(accessory).
The rotary current motors are connected to the corre-
sponding switching units in accordance with the respec-
tive electrical wiring diagrams.
The corresponding power fuse in the line to the switch-
ing unit must be installed by the customer in line with
the relevant regulations.
The connections in the terminal box of the unit must be
connected to the corresponding switching unit
(accessory).
Connecting the fan motor
Motor with 2 speeds, Y/∆ switch and thermal contacts.
High-speed ∆switch
When the fan is idle, the heating medium supply
must be interrupted.
*
◊ The units operate on the principle of counter-current:
The water (supply line) usually comes in at the bottom,
the water (return line) usually goes out at the top
◊ Once assembled, the heat-exchanger must be care-
fully ventilated because air pockets in the register
can reduce unit performance.
Important information about frost protection!
To prevent frost damage, a frost protection mechanism
must be attached for temperatures below 0 °C.
There may not be any water in the heat-exchanger for
systems taken out of operation in rooms susceptible to
frost. The remaining water must be blown out with com-
pressed air.
If this is not possible, the heating medium (water) must
be mixed with a suitable anti-freeze.
Restriction of guarantee!
Non-compliance with the relative legal requirements,
operating instructions and unit-specific wiring diagrams
can lead to malfunctions that cause damage.
In cases of non-compliance, the guarantee becomes null
and void!
Low speed Y switch
Connecting several units
If necessary, several units (even of different sizes) can
be operated at the same time via a switching unit
(accessory).
The overall capacity of the connected units may not,
however, exceed the maximum electrical capacity of the
corresponding switching unit.
For thermal motor protection, the thermal contacts of all
motors are to be connected in a row. Follow the sepa-
rate wiring diagrams.
There can never be more than one external regulating
mechanism per switching unit connected at a single time!

Electrical Connection
The requirements of the local energy supply company
as well as installation requirements specific for each
unit must be observed.
The electrical connection may only be made by
trained and authorised personnel.
*
No guarantee claims can be made for frost damage
on the heat-exchanger!
*
When connecting the screw attachments of the
heating medium connection, a suitable tool should
be used to apply counter-pressure to prevent dam-
age caused by turning the connection lines.
