15.8 - Water evaporator/condenser

The evaporator/condenser is a plate heat exchanger with one or 
two refrigerant circuits. The water connection of the heat exchanger 
is a Victaulic connection. It has a thermal insulation of 19 mm thick 
polyurethane foam and includes frost protection, as standard.
The  products  that  may  be  added  for  thermal  insulation  of  the 
containers during the water piping connection procedure must be 
chemically neutral in relation to the materials and coatings to which 
they are applied. This is also the case for the products originally 
supplied by Carrier SCS.
NOTES - Monitoring during operation:
• Follow the regulations on monitoring pressurised
equipment.
• It is normally required that the user or operator sets up
and maintains a monitoring and maintenance file.
• If there are no regulations or to complement them follow
the control programmes of EN 378.
• If they exist follow local professional recommendations.
• Regularly check for possible presence of impurities
(e.g. silica grains) in the heat exchange fluids. These
impurities maybe the cause of the wear or corrosion
by puncture.
• The reports of periodical checks by the user or operator
must be included in the supervision and maintenance
file.

15.9 - Refrigerant

30RQS/RQSY units operate with refrigerant R-410A.

15.10 - High-pressure safety switch

30RQS/RQSY units are equipped with automatically reset safety 
pressure  switches  on  the  high-pressure  side.  For  the  alarm 
acknowledgements refer to the 30RB/RQ Touch Pilot Junior control

15.11 - Storage tank

30RQS/RQSY  units  are  equipped  with  mechanically  welded 
storage tanks that permit storing the excess charge when the unit 
operates in heating mode. 

15.12 - Four-way valve

This  permits  reversal  of  the  cycle  for  operation  in  cooling  and 
heating mode and during defrost cycles.

15.13 - Control box

The control box of the 30rqs/rqsy units is equipped with electric 
heaters to prevent condensation during operation at low outside 
temperatures. they are installed on the top of the control box on 
the outside, and are covered by a thermal insulation layer. these 
heaters are switched on, based on the outside temperature.
