DESCRIPTION – OPERATIONS
The PROFROID GQ condensing unit is made up primarily of:
-
1 or 2 COPELAND hermetic scroll compressor ZB or ZF (1 compressor digital forstandard range),
-
1 air-cooled condenser with 1 or 2 EC centrifugal fans (T3 or T4),
-
1 liquid receiver, 1 safety valve following volume,
-
1 filter drier, 1 sight glass,
-
1 muffler on dischargeline,
-
1 electrical cabinet, 1 mains witch,
-
safety : 1 high and 1 low pressure switches percompressor
-
control : standard range : 1 electronic controller for LPandHP
Unit power supply :
400V ±10% / 3 + N / 50Hz (Neutral EN as standard + neutral + Earth
The set-up is mounted on a galvanised folded, sheet steel frame, with white painted sheet metal side
panels. The unit is specially designed to reduce noise and vibration.
The unit can be provided with remote electronic controller PROCOLD
(optional). The QUIETOR range is divided in two parts :
Medium temperature : -20°C -> +5°C (Fluid : R134a, R407F,R404A, R407A, R448A, R449A or
R507A) Low temperature : -40°C -> -20°C (Fluid : R407F,R404A, R448A, R449A or R507A)
Options :
Room control by remote electronic controller.
Special coating in corrosive atmosphere (by Blygold protection).
Waterproof remote control box (on-off switch, light,
5 m of
cable). Oil
separator
Oil separator+ traxoil+oil receiver 4liters for TWIN models
only. Manometers
SCROLL DIGITAL VERSION
This device is able to modulate capacity between 10 and 100% (by separating the scroll set axially over a short period of time
Capacity is controlled by specific controller function of suction pressure EC2-552 (find attached notice)
This technology is interesting for multiple evaporators' installations and for applications requiring precise temperature control.
2- INSTALLATION
HANDLING
Units have 4 attachment lugs for handling (situated on 4 frame angles).
During handling of condensing units with a crane, lifting hooks will be fix to the 4 attachments lugs.
SPECIFIC INSTALLATION RECOMMENDATIONS
The unit must be put and fixed to a ground plan supporting the weight of the unit (concrete slab).
The fixing (4 fixing points provided) must be direct on the ground without any intermediate device such as flexible support, rail, studs,....
The details of the centers of the 4 fixing points are given in sketches at the end of this document
The unit must be exactly level in order to avoid creating an accumulation of oil at the lowest point, in the suction and discharge pipes, or
causing vibrations.
Any other assembly (such as installation in a spandrel) must be the subject of a structural study adapted to the frame of the unit and remains the
responsibility of the installer.
In the case of mounting on a specific frame, you will find our recommendations concerning the location of the supports in sketch at the end of this
document.
No obstacles should be allowed to prevent air from being drawn from the coil and the fan to
discharge. Sufficient space should be allowed:
-
1 m minimum on the fan side and electrical cabinet side for servicing and maintenance operations.
-
0.7 m minimum on the coilside.
