Connections; Condensate Drain Siphon; Heating/Cooling Coil - CIAT Climaciat Instruction Manual

7 - CONNECTIONS

7.1. Condensate drain siphon

ƒ Connecting the siphon
Position, diameter and type of connector, see dimensional drawing.
Outlet on the front panel: Threaded gas type steel connector.
Outlet in frame: Smooth rubber female sleeve for 32 mm PVC bonding tube.
Mastic bonding is recommended for the hygiene tank connection.
The siphons and drain pipes must be insulated and protected from frost (heating cable).
The siphons must not be directly connected to the waste water network.
ƒ Siphon calculation:
H in mm = Pa / 10
Pa = Pressure difference (in Pascal) between the inside and outside of the unit.
ƒ Assembly with depression :
ƒ Assembly with several coils in parallel:
OK

7.2 Heating/cooling coil

7.2.1 Coil supply:
Follow the instructions on the labels:
Observe the counter-flow principle
- Fluid inlet downstream of the air flow direction
- Fluid outlet upstream of the air flow direction
7.2.2 Connection
ƒ Refer to your dimensional drawing for the diameters of the connections and their positions.
ƒ Before connecting, make sure the inside of the hydraulic system pipes is perfectly clean and free from debris or deposits.
ƒ The pipe routing and insulation must not obstruct the removal of the heat exchanger for replacement or maintenance. Use
removable connectors and insulation components (valves).
ƒ The system pipes must be affixed to the walls, ceiling or floor of the building, and must under no circumstances exert an
additional load on the unit. Make sure the pipes are supported.
ƒ The pipes must not transmit any thermal or vibrational stress to the heat exchanger. Use expansion sleeves. Do not use
galvanised connectors. Check the material compatibility (risk of electrolysis).
ƒ The pipes must be insulated to prevent condensation and heat loss.
Make sure the insulation is no thicker than 40 mm to leave enough space to open the doors or removable panels.
ƒ Assembly with pressure:
