HYDRAULIC CONNECTIONS
The pipe installation and connection operations can compromise the good operation of the system or worse, cause irreversible damage
to the machine.
Therefore, these operations must only be carried out by specialised personnel.
CONDENSATE DISCHARGE CONNECTION
• The condensate collection tank is equipped with a drain.
• The path of the condensate discharge pipe must always have a slope towards the outside.
• Make sure that the condensate drain pipe does not strain the discharge connection of the unit
CONNECTION OF ANY WATER POST-HEATING COIL
• Any water post-heating coil is equipped with “male” connections with gas threading.
• Tightening operations must be carefully carried out to avoid damaging the copper manifolds of the coil.
• The pipe path must be designed so as not to create obstructions in the removal of the unit’s coil.
• The water inlet and outlet must be such as to allow heat exchange in countercurrent: therefore, follow the indications of the WATER
INLET and WATER OUTLET plates.
• Provide a vent valve at the top and a drain valve at the bottom.
• Fix the pipes properly outside the unit to avoid bearing their weight on the coil.
• When the connection is made, push the outer rubber gasket well against the panel to avoid air leaks.
• The insulation must be flush with the panel to avoid burns.
• Provide, at regulation level, the shut-off of the pipe side coil with the fan off to prevent overheating inside the control unit with possible
damage to some components.
• Provide an antifreeze device.
• Provide shut-off valves to isolate the coil from the rest of the circuit in case of extraordinary maintenance.
• In case of installation in areas with particularly cold climates, drain the system for any long system downtime.
ELECTRICAL CONNECTIONS
• To perform the electrical connections, refer to the RCE-EC control unit instruction manual.
• Before starting any operation, make sure that the main power supply line is disconnected.
• The electrical connections to the control panels must be carried out by specialised personnel according to the diagrams provided.
• Make sure that the voltage and frequency indicated on the plate match those of the electrical connection line.
• The use of adapters, multiple sockets and/or extensions is not allowed for the general power supply of the unit and accessories.
• The installer must provide a power supply cut-out switch for the type of installation as close as possible to the unit, together with all
that is necessary to protect the electrical parts.
• Connect the unit to an effective earth socket, using the appropriate screw inserted in the unit itself.
• Connect the unit and all its accessories with cables of suitable section for the power used and in compliance with local regulations.
However, their size must be such that a voltage drop in the start-up phase is less than 3% of the nominal one.
