Electric Heater; Droplet Eliminator - CIAT Climaciat Instruction Manual

7.2.3 Fitting the control valves (optional)
Carry out installation in accordance with the plan supplied with the kit.
The pipes and valves must not under any circumstances place any additional load on the unit. The pipes must be supported on
the wall or floor of the building.
The valve motors must have frost protection if they are likely to be subjected to temperatures below -10°C (motor environment).
For valves installed outdoors, provide an enclosure for the motors to protect them from the weather.
7.2.4 Bleeding, draining, filling
In accordance with industry practice, provide a bleed hole at the high point and a draining and filling hole at the low point for each
hydraulic circuit.
It is recommended to use a filling device with a check valve.
To comply with anti-pollution standard NF EN1717 or the regulations in force at the installation location. The device must
under no circumstances be connected to the municipal water supply unless the additives used in the hydraulic circuit have
been approved by the ministry of health (e.g. monopropylene glycol (MPG) products with NEUTRAGEL SANIT or HELIOGEL
CS 80 approval).

7.3 Electric heater

Risk of fire and unit damage if the air flow is absent or too low:
- Use an air flow control device set in accordance with the dissipated heating power,
- The operation of the heating coil must be fan-controlled.
- A fan delay of at least 15 minutes must be applied after the electric heater has been switched off,
- In variable flow operation, power staging is recommended for the electric elements (multi-stage or TRIAC) and they should
operate proportionally with the air flow rate.
7.3.1 Connection:
Always follow the general safety instructions.
ƒ For machines supplied without a control unit:
- When selecting the cables, take into account the routing, the ambient operating temperature and the current of the
connected heaters.
- The selection, securing and mechanical and electrical protection of cables must conform to the regulations and laws at
the installation site.
- The power electrical connections are made directly on the heaters. Observe the tightening torque of 4 Nm,
- The safety components must be connected,
- The installed safety thermostats must cut the power supply to the heating elements,
- The safety components must be electrically connected directly to the terminals of the thermostats with manual and
automatic reset located on top of the heater. They must be connected and cut the supply control to the electric elements,
- Coloured labels indicate the stage marking, their output per unit and the phase order.
Do not connect the electric heater to the ground (class 2 insulation).
ƒ For machines supplied with a control unit:
- The heaters are supplied cabled to a specific unit nearby,
- This unit must have a specific power supply. When selecting the cables, take into account the routing, the ambient
operating temperature and the current of the connected heaters.
- The selection, securing and mechanical and electrical protection of cables must conform to the regulations and laws at the
installation site. Follow the recommendations in the regulations section when selecting components and cables,
- Unwind the electric heater control unit cable(s) to the main unit. Route them by sliding them into the lower raceways (before
assembling the blocks) or upper raceways (depending on the position of the electric heater in the unit).
- Use the wall feedthroughs in the block concerned.
7.3.2 Connection:
ƒ See wiring diagram.

7.4 Droplet eliminator

The pipe routing and insulation must not obstruct access or clearance for the slide of the antifreeze thermostat and/or droplet
eliminator (shaded area).
