connected and tested.The electric box has a door with a block- ing mechanism and contains the compressor and fan contac- tors, fuses and electrical protection. Also has IP44 protec- tion.
Centrifugal fans
Transmission is by belts and removable core pulleys. The motors are mounted on tensing bases fastened directly to the fan casing.
Two versions are available: with horizontal or vertical air dis- charge
Compatible with the following units:
GH200 | for size 42 |
GH260 | for sizes 62 and 82 |
GH600S | for sizes 102 and 122 |
GH600P | for size 152 |

Accessories
Hydro kit GH
Includes: Buffer tank, automatic air purger, pressure gauge, automatic 1.5 bar filling valve, expansion vessel, pump, flow switch, drain valve, safety valve and electronic board for in- terconnection. Available in 200, 260 and 600 litre capacities. There are two versions of GH600: GH600S and GH600P.
DI buffer tanks
Cylindrical shape and in vertical position. Available in 200, 260 and 600 litre capacities.
Low ambient kit (factory-mounted, optional)
This accessory allows operation of the unit when the con- densing outdoor air temperature is below 10° C.
General information
This accessory controls condensing pressure in the winter cycle by varying air flow through the outdoor coils. This flow variation keeps condensing pressure constant when outdoor temperatures are low.
Operation
By means of the pressure detected through the analogical pressure switches installed in the cooling circuit, and carry- ing out the appropriate calculations as programmed, this con- trol generates an analogical signal that opens the dampers to maintain the condensing pressure previously programmed as the set point.
