If the chiller is to be stored for more than one month
prior to installation, observe the following precautions:
38/41/44 46/50/53
• Store the chiller in a dry, vibration-free, secure area.
48/51/54 56/60/63
• Units charged with refrigerant should not be stored
1090 x 710 1290 x 820
where temperatures exceed 68°C.
300
• At least every three months, attach a gauge and
manually check the pressure in the refrigerant circuit. 1133 x 754 1333 x 864
310
If the refrigerant pressure is below 13 bar at 20°C
46
(or 10 bar at 10°C), call a qualified service organization
galvanised steel
and the appropriate Trane sales office.
8/16 8/16
• If the refrigerant pressure is below 13 bar (R410A)
40 (230V),3*16 (400V) 3*20
/ 12.5 bar (R454B) at 20°C or 10 bar (R410A) / 9.5 bar
(R454B) at 10°C, call a qualified service organization or
Trane Sales Office.
The Trane Company will not assume responsibility for
equipment damage resulting from accumulation of
condensate on the unit electrical components.
Note: if the unit is stored before servicing near a
construction site it is highly recommended to protect
micro channel coils from any concrete and iron element.
Failure to do so may considerably reduce reliability of
the unit.
