1 - INTRODUCTION

Prior to the initial start-up of the 30RQ units, the people
involved should be thoroughly familiar with these instructions.
The 30RQ heat pumps are designed to provide a very high level
of safety and reliability making installation, start-up, operation
and maintenance easier and more secure. They will provide
safe and reliable service when operated within their application
range.
The procedures in this manual are arranged in the sequence
required for machine installation, start-up, operation and
maintenance.
Be sure you understand and follow the procedures and safety
precautions contained in the instructions supplied with the
machine, as well as those listed in this guide, such as: protective
clothing such as gloves, safety glasses, safety shoes and appro-
priate tools, and suitable qualifications (electrical, air condi-
tioning, local legislation).

1.1 - Check equipment received

• Confirm that the unit received is the one ordered. Compare
the name plate data with the order. The nameplate is
attached to the control box door on the inside.
• The unit name plate must include the following information:
- Model number - size
- CE marking
- Serial number
- Year of manufacture and pressure and leak tightness
test date
- Refrigerant used
- Refrigerant charge per circuit
- PS: Min./max. allowable pressure (high and low
pressure side)
- TS: Min./max. allowable temperature (high and low
pressure side)
- Globe valve cut-out pressure
- Pressure switch cut-out pressure
- Unit leak test pressure
- Voltage, frequency, number of phases
- Maximum current drawn
- Maximum power input
- Unit net weight
• Confirm that all accessories ordered for on-site installation
have been delivered, and are complete and undamaged.
The unit must be checked periodically, if necessary removing
the insulation (thermal, acoustic), during its whole operating
life to ensure that no shocks (handling accessories, tools etc.)
have damaged it. If necessary, the damaged parts must be
repaired or replaced. See also chapter "Maintenance".

1.2 - Installation safety considerations

After the unit has been received, and before it is started up, it
must be inspected for damage. Check that the refrigerant
circuits are intact, especially that no components or pipes have
shifted or been damaged (e.g. following a shock). If in doubt,
carry out a leak tightness check. If damage is detected upon
receipt, immediately file a claim with the shipping company.

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 desig-
nated lifting points marked on the unit (labels on the chassis
and a label with all unit handling instructions are attached to
the unit).
Use slings with the correct capacity, and always follow the
lifting instructions on the certified drawings supplied for 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 globe valve in the water circuit and the
globe valve(s) in the cooling circuit(s).
Ensure that the valves are correctly installed, before
operating the unit.
The globe stops are designed and installed to ensure
protection against fire risk. Removing the globe stops is only
permitted if the fire risk is fully controlled and the
responsibility of the user.
All factory-installed globe valves are lead-sealed to prevent
any calibration change.
The safety valves must be connected to discharge pipes for
units installed in confined spaces. 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.
Globe valves must be checked periodically. See paragraph
"Repair safety considerations".
Provide a drain in the discharge circuit, close to each globe
valve, to avoid an accumulation of condensate or rain water.
All precautions concerning handling of refrigerant must be
observed in accordance with local regulations.

1.3 - Equipment and components under pressure

These products incorporate equipment or components under
pressure, manufactured by Carrier or other manufacturers. We
recommend that you consult your appropriate national trade
association or the owner of the equipment or components under
pressure (declaration, re-qualification, retesting, etc.). The
characteristics of this equipment/these components are given
on the nameplate or in the required documentation, supplied
with the products.
These units comply with the European Pressure Equipment
Directive.
