2.7.2 Connecting the heat exchanger condensate drain
Our condensate collection trays are fitted with a drain that passes through the floor, comprising a plug and a PVC pipe Ø32. The membrane water trap
is delivered in the box of separate parts. Connect the membrane water trap to the evacuation pipe.
Attention:
Respect the condensate drainage direction indicated by an arrow on the connector.
2.7.3 Connecting the cooling coil condensate drain
Our cooling coil condensate collection trays are fitted with a plug attached to an extendible hose discharging at the access panel spar under the cool-
ing coil. The end of the PVC hose has a male Ø32 end piece. Connect the discharge hose to a water trap (refer to section 2.8.1) by attaching a female
PVC Ø32 end piece.
2.7.4 Connecting the internal water coil collectors
Refer to section 3.4 for collector diameters and their positions.
Collectors have a standard thread. Attach the water inlets and outlets on the coil collectors.
The collector water inlets and outlets are identified on the side panels of the Unit (the water circuit always runs counter to the air circuit on a coil con-
taining at least two rows). We recommend that you hold the collector with a clamp while connecting it, to prevent damage to the collector that could
cause leaks.
Ensure the joints on the collectors are sealed and use an expansion seal or flexible connection to absorb any expansion or contraction.
Refer to section 3.4 for nominal diameters of the 3-way valves.
NB:
Coils admit a maximum pressure of 8 bar.
2.8 Connecting to mains power
Caution:
electrical connections should be made by a qualified electrician equipped with suitable Personal Protective Equipment. Never perform work
on the Unit while it is energized. The electrical connection shall respect NF-C 15-100. Each power supply network must be protected with an omni-pole
circuit breaker with an opening distance of 3 mm on each contact. For a single-phase power supply, use a type A differential leak current circuit breaker.
For a 3-phase supply, use a type B circuit breaker. We recommend a differential of 300 mA for these two types of power supply. The amperage rating
required for each circuit breaker according to the size of the Unit is defined in sections 2.8.3 and 2.8.4. Maximum recommended ambient temperature
< 45 °C.
Remember to connect to the Earth circuit.
