SmartCool 6 - 200kW Chilled Water Technical Manual 7674716 V1.10.0_10_2018

Environmental Considerations
Units with supply water temperatures below +5°C
●Glycol is recommended when a supply water temperature of +5°C or below is required or when static water can
be exposed to freezing temperatures.
Units subject to ambient temperatures lower than 0°C
●Glycol of an appropriate concentration (1) must be used within the system to ensure adequate freeze protection.
Please ensure that the concentration is capable of protection to at least 3K lower than ambient.
●Water / glycol solution should be constantly circulated through all waterside pipework and coils to avoid static
water from freezing.
●Ensure that pumps are started and running even during shut down periods, when the ambient is within 3K of the
solution freeze point (1) (i.e. if the solution freezes at 0°C, the pump must be operating at 3°C ambient).
●Additional trace heating is provided for interconnecting pipework.
(1) Refer to your glycol supplier for details.
Environmental Policy
It is our policy to:
●Take a proactive approach to resolve environmental issues and ensure compliance with regulatory requirements.
●Train personnel in sound environmental practices.
●Pursue opportunities to conserve resources, prevent pollution and eliminate waste.
●Manufacture products in a responsible manner with minimum impact on the environment.
●Reduce our use of chemicals and minimise their release to the environment.
●Measure, control and verify environmental performance through internal and external audits.
●Continually improve our environmental performance.

Pressure Equipment Directive (2014/68/EU)
Minimum and Maximum Operation Temperature (TS) and Pressure (PS)
Waterside
Allowable Temperature Range (TS) = Min -5°C* to Max 40°C**
Maximum Allowable Pressure (PS) = 10 Barg
*Based on the waterside temperature in the unit off state in the lowest permitted ambient temperature.
**Based upon maximum machine running temperatures.
Ecodesign Directive 2009/125/EC
The product range within this document is designed in accordance to the European Ecodesign Directive 2009/125/EC.
The appendix at the rear section of the manual gives the product compliancy metrics. Products sold outside of the EU
are exempt from this directive.
When working with any air conditioning units ensure that the electrical isolator is switched off prior
to servicing or repair work and that there is no power to any part of the equipment.
Also ensure that there are no other power feeds to the unit such as fi re alarm circuits, BMS circuits
etc.

Introduction

Electronically Commutated (EC) Fan Motor
EC motors incorporate integrated electronics to convert AC power to DC for efcient and accurate speed control and are
adjustable via the microprocessor display keypad.
The fans offer maximum air ow performance while keeping sound levels to a minimum.
It gives the exibility of connecting to AC mains with the efciency and simple speed control of a DC motor. The EC fan
offers signicant power reduction in comparison with an equivalent AC fan at modulated fan speeds. The inbuilt EC fan
control module allows for fan speed modulation from 15-100%.
A standard AC fans modulating range is typically 40 -100% of full fan speed.
Standard voltage regulated (VR) fan speed controllers offer a linear response. The illustration on the right shows a
comparison of the typical power input required by each method.
