Installation, operation and maintenance instructions - VMGFE102
1 INTRODUCTION
Prior to the initial start-up of the AR05 units, the people
involved should be thoroughly familiar with these instructions
and the specifi c project data for the installation site.
The AR05 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 appropriate tools, and suitable qualifi cations
(electrical, air conditioning, local legislation).
To fi nd out, if these products comply with European direc-
tives (machine safety, low voltage, electromagnetic compati-
bility, equipment under pressure, etc.) check the declarations of
conformity for these products.
1.2 - Check equipment received
•
Inspect the unit for damage or missing parts. If damage is
detected, or if shipment is incomplete, immediately fi le a
claim with the shipping company.

on the outside on one of the unit sides
-
on the inside of the control box
This shows 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
• Confi rm 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”.
