1 - INTRODUCTION
The 30XQ Aquaforce units are designed for the air conditioning of buildings and industrial processes. Prior to the initial
start-up of the 30XQ units, the people involved in the on-site installation, start-up, operation, and maintenance of this unit
should be thoroughly familiar with these instructions and the specific project data for the installation site.
The 30XQ heat pump chillers are designed to provide a very high level of safety during installation, start-up, operation
and maintenance. They will provide safe and reliable service when operated within their application range.
This manual provides the necessary information to familiarize yourself with the control system before performing start-up
procedures. The procedures in this manual are arranged in the sequence required for machine installation, start-up, operation
and maintenance.
Always ensure that all required safety measures are followed, including those in this document, such as: wearing
protective clothing (gloves, shoes) and safety glasses, using appropriate tools, employing qualified and skilled
technicians(electricians, refrigeration engineers) and following local regulations.
1.1 - Installation safety considerations
Access to the unit must be reserved to authorized personnel, qualified and trained in monitoring and maintenance. The
access limitation device must be installed by the customer (e.g. cut-off, enclosure).
After the unit has been received, when it is ready to be installed or reinstalled, and before it is started up, it must be
inspected for damage. Check that the refrigerant circuit(s) is (are) intact, especially that no components or pipes have shifted
(e.g. following a shock). If in doubt, carry out a leak tightness check and verify with the manufacturer that the circuit integrity
has not been impaired. If damage is detected upon receipt, immediately file a claim with the shipping company.
Carrier strongly recommends employing a specialized company to unload the machine.
Do not remove the skid or the packaging until the unit is in its final position. These units can be moved with a fork lift truck,
as long as the forks are positioned in the right place and direction on the unit.
The units can also be lifted with slings, using only the designated lifting points marked on the unit.
These units are not designed to be lifted from above. Use slings with the correct capacity, and always follow the
lifting instructions on the certified drawings supplied with the unit.
Safety is only guaranteed, if these instructions are carefully followed. If this is not the case, there is a risk of material
deterioration and injuries to personnel.
Never cover any safety devices. This applies to the relief valve in the water circuit and the relief valve(s) in the refrigerant
circuit(s). Ensure that the valves are correctly installed, before operating the unit.
If the unit is installed in a room, the safety valves must be connected to discharge pipes. These pipes must be installed in a
way that ensures that people and property are not exposed to refrigerant leaks. These fluids may be diffused in the air, but
far away from any building air intake, or they must be discharged in a quantity that is appropriate for a suitably absorbing
environment.
Periodic check of the relief valves: See paragraph
"Maintenance safety considerations".
Provide a drain in the discharge circuit, close to each relief valve, to avoid an accumulation of condensate or rain water.
Ensure good ventilation, as accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation
or explosions.
Inhalation of high concentrations of vapour is harmful and may cause heart irregularities, unconsciousness, or death.
Vapour is heavier than air and reduces the amount of oxygen available for breathing. These products cause eye and skin
irritation. Decomposition products are hazardous.
