Ultima Compact 30-150kW Technical Manual 9690553 V1.2.0_10_2019
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.
Flow Control
Full design water fl ow MUST be maintained at all times. Variable water volume is NOT recommended and will invalidate
warranty. Care to be taken when selecting a chiller within 5% of the evaporator minimum fl ow rate. The end user must
ensure that fl ow variation does not fall below this minimum as the chiller will shut down.
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.

To comply with these directives appropriate national & harmonised standards have been applied. These are listed on the
Declaration of Conformity, supplied with each product.
Occupancy Note
When placing a chiller the access category for the surrounding area needs to be classifi ed in accordance with
EN 378-1:2016 section 5.1.1.
Access to the Ultima range should be limited to supervised or authorised access only (access categories B and C) as
described in EN378-1:2016 Table 4. This access level needs to be confi rmed by the end user, and the location within
which the product is to be installed needs to be defi ned. EN 378-1:2016 section 5.3 describes the four main types of
location and the hazards associated with each. The Ultima Range has been designed to be installed in an open air
environment (location class III) and shall not be applied in alternative locations.
As an air cooled Chiller typically in an ‘Authorized Access’ installation, located in open air, ‘Class III’ location,
EN378-1:2016 Table C.2 states that there is ‘No charge restriction’ for these systems using R32 (A2L) refrigerant.
