8. CONDENSATE PUMP  DRAINAGE SYSTEM
By default, SLIM units are delivered with an integrated silent running centrifugal pump. The pump will activate automa-
tically when the level of condensate grows over a set point.
If there is any problem related with the condensates drainage (defective pump, maximum level of condensates reached,
etc.) unit will display an alarm in the external touch display. The unit will stop working in case of major failure.
The condensate pump is available as a spare and very easy to replace (it is located inside the drainage tray). Look for the
spare part code of the condensate pump in section "34.2. Spare parts list".
Main characteristics:
• Electronic Energy Control System (EECS) with alarm circuit. All electronic components are encapsulated to protect
them from moisture.
• Max flow capacity: 12 l/h
• Max suction height: 1 m Max delivery height: 19,8 m Discharge tube: ø6 mm

10. FILTER REPLACEMENT
The heat recovery unit is supplied within a F7 (ePM1 50%) filter in the supply side and M5 (ePM10 50%) filter in the ex-
tract side. There is no possibility to mount a second filter inside the unit.
The supplied filters can be removed both from bottom (1) and side (2):
10.1. REMOVING THE FILTER THROUGH THE BOTTOM
a) Open the specific hinged panel for
filter replacement.
b) Push from the fixation pieces to loose the filtration box.
c) Remove the filtration box. d) Remove the filter from the filtration box: first step is to push from the pie-
ces that fix the filter to the box. Then, the filter will be liberated.
Do not threw the filtration box away, you will
need it to put the spare filter inside the unit.
10.2. REMOVING THE FILTER THROUGH THE LATERAL
a) Remove the specific panel for filter
replacement.
b) Push from the fixation pieces.
c) Remove the filter. The filtration box remains inside the unit.

12. INTEGRATION IN “DX” DIRECT EXPANSION SYSTEMS
The SLIM controller does not allow to control the components of the refrigeration circuit. It is essential to provide the
rest of components of the refrigeration circuit (not supplied by S&P) such as:
• Refrigeration condensing unit (compressor-condenser)
• DX direct expansion valves
• DX system control
With regard to the selection of components, verify the following:
• The condensing unit allows to obtain the required thermal capacity by the DX coil, considering the real working condi-
tions (Temperature and ambient relative humidity and evaporation temperature considered).
• DX coil pressure drop as well as internal coil volume are compatibles with the KIT DX VALVE (not supplied by S&P) and
the refrigeration condensing unit.
13. DUCTS AND PIPING CONNECTIONS
13.1. CONNECTION WITH AIR DUCT
Before making the ductwork connections, identify the labels in each inlet/outlet of the heat recovery unit.

13.1.2. Isolation dampers (accessory)
We strongly recommend to install isolation dampers in the outdoor air connections ir order to protect the unit in winter,
during the night or during periods of prolonged unit stoppage. When talking about the indoor air connections, If the
ductwork is expected to pass through cold areas, it must be isolated.

13.2. CONNECTION WITH COIL PIPING
• When connecting a coil to the water network:
− Maximum pressure: 10 bar
− Maximum temperature: 100ºC
− Minimum water temperature: -20ºC (with the addition of the corresponding
antifreeze)
• SLIM coils have threaded connections. Secure the coil manifold with the
appropriate tool when tightening the threads. This will prevent the force from
being transmitted to the manifold, damaging it.
• The following table indicates the size and type of thread used on each coil model:
Model/size SL-DC
(Heating water coil)
SL-DFR
(Reversible water coil)
SL-DF
(Chilled water coil)
SL-DX
(Direct expansion coil)
800 1/2” 1/2” 1/2” 1/2”

1600 1/2” 3/4” 1/2” 1/2”
2000 1/2” 3/4” 3/4” 1/2”
• To ensure the good behaviour of the installation, it is essential that the installation includes the following elements:
− Unit intake pre-filter which traps suspended particulate matter.
− Bleed valves should be fitted at each of the high points in the installation.
− Self-filling valve to keep the appropriate water level.
− Pressure switch to detect the lack of water pressure.
− Shut-off valves must be installed at each connection on the water line to allow the unit to be isolated if necessary
(allowing filters cleaning, reparations and maintenance tasks) the need to completely drain the water circuit.
− Anti-vibration devices should be installed at the inlet and outlet from the unit to prevent the transmission of vibra-
tions that could damage the heat exchanger coil due to excess stress on the circuits.
• Once the installation is performed check that the heating water flow is adequate.
14. ELECTRICAL CONNECTIONS
All components integrated in the device are electrically wired into the electrical cabinet (fans, pressure transmitters,
pressure switches, temperature probes and by-pass damper).
The electrical connection is then limited to the connection of the external display (10 m. of supplied cable) and possible
electrical accessories such as CO2 sensors or control valves for water coils, and finally the connection of the power
supply line.
Make electrical connection in accordance to the described in the corresponding wiring diagram.
