Auxiliary Condensate Pan Drain Connection; Connecting The Condensate Drain Pump (Option) - Carrier 42KY serie Bedienungsanleitung

To protect against the risk of condensation when using chilled water, lagging should be installed along the entire pipe-run and
vapour sealed at its ends. 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. Auxiliary 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 drain connector will accept pipes with an internal
diameter of 15 to 20 mm. Ensure that the drain connector 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 device or connected to a main drain pipe sized to allow the condensate
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 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:
- Maximum flow of 16 l/h for a head height of 2 metres and a maximum pipe length of 5 metres.
- Maximum flow of 15 l/h for a head height of 2 metres and a maximum pipe length of 10 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.

Under operating conditions outside the recommended temperature and relative humidity range (page Fr-1), the discharge
pipe must be insulated to prevent condensation, which could damage the installation and the pump. We recommend using a
transparent colourless PVC type pipe with internal diameter 6 mm/external diameter 9 mm. It is essential to ensure that the pump
connections are sealed. A clamp can be used for this purpose.
Important: Check the unit selection data to determine the maximum condensate flow rate.
Note: This accessory must always be used with a valve control device, to ensure valve control of the high safety device when
the valve is closed (closure of the condensate drains).
