4.3.8 - Operating recommendations:
To prevent any inopportune opening of the thermo-actuators on control valves with thermal motors, the temperature
of the air surrounding the thermo-actuators should not exceed 50°C. This is especially important for units installed
in confined spaces (e.g. in suspended ceilings).
CIAT shall not be liable for damage to valves caused by faulty design of the hydraulic supply network or incorrect
commissioning.
To protect against the risk of condensation when using chilled water, lagging should be placed along the entire
lengths of pipes and the ends must be completely sealed. When using the water coil and electrical heater, we
advise against using cross-linked polyethylene (PEX) pipes to supply water to the unit. This is because overheating
of the electrical heater could cause the water temperature to rise briefly.
This could cause the rapid deterioration of the PEX pipe near the unit and cause it to burst. We recommend using
stainless steel braided (or equivalent) hoses for hydraulic connections.
4.4 - Condensate pump draining connection
For size 0:
The condensate pan is inclined with no water retention, and equipped with a 16 mm external diameter end piece.
(Fig.9, a).
For sizes 1 to 6:
The condensate pan is inclined with no water retention, equipped with a 22 mm external diameter end piece and
a plug supplied with the unit.
The installer can change the condensate draining side by switching the bushing and the cap (fig.9, b).
The drain pipe can be separate for each unit or connected to a main drain pipe sized to allow the condensates from
all the units to flow through at the same time. Use a clear flexible and/or rigid drain pipe with a minimum slope of
1 cm/m, with a constant gradient along its whole length and no low points.
Install a siphon trap measuring at least 5 cm to prevent unpleasant gases or odours venting from the drain.
4.5 - Connecting the condensate drain pump (option)
The condensate drain pump can be supplied mounted on the unit as an option Its technical specifications are as
follows:
For sizes 0 to 5:
■ Maximum flow of 8,5 l/h for a pumping height of 2 metres and a horizontal pipe length of 5 metres.
■ Maximum flow of 7 l/h for a pumping height of 4 metres and a horizontal pipe length of 5 metres.
The operation points are provided in the table below.
Connect a clear drain pipe (not supplied) with an internal diameter of 6 mm between the pump outlet and the
wastewater pipe. This pipe should not be pinched or touch the unit or any other external component.
