30RQS/RQSY units operate with refrigerant R-410A.
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 manual).
30RQS/RQSY units are equipped with mechanically welded
storage tanks that permit storing the excess charge when the
unit operates in heating mode.
This permits reversal of the cycle for operation in cooling
and heating mode and during defrost cycles.
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.
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 le.
• 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.
silicon grains) in the heat exchange uids. 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 le.
According to the Regulation No. 640/2009 and amendment 4/2014 implementing Directive 2005/32/EC with regard to
ecodesign requirements for electric motors.
