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 completely sealed at its ends.
When using the water coil and electric heater, we advise against using cross-linked
polyethylene (PEX) pipes to supply water to the unit. This is because overheating of
the electric 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 pan draining connection
A naturally inclined ABS auxiliary condensate drain pan, with no water retention, is
supplied with the unit.
To install this auxiliary pan, proceed as follows:
- Remove the bolt (Fig. 17, a)
- Clip on the auxiliary pan
- Refit the bolt and tighten it (Fig. 17, b).
The condensate is drained via the drain hole in the pan (drain height 70 mm); This
hole can receive tubes with an internal diameter of 15 to 20 mm. Ensure that the
drainage bushing is the lowest point on the auxiliary pan so that water does not
accumulate in the pan. 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 for a minimum slope of
1 cm/m, with a constant gradient along its whole length and no low points. Install a
trap measuring at least 5 cm to prevent unpleasant gases or odours exiting the hose.
