(1) Weights are guidelines only. The refrigerant charge is given on the unit nameplate.
(2) Minimum unit capacity corresponds to a physical state of the unit and is given for indication only. The actual capacity at this stage depends on operating conditions.

(1) For low-temperature applications, where the leaving water temperature is
below 3.3°C, a frost protection solution must be used. Please refer to option 5
and option 6.
(2) For lower condenser temperatures a water flow control valve must be used at
the condenser (two or three-way valve). Please refer to option 152 to ensure
the correct condensing temperature.
Note:
Ambient temperatures: During storage and transport of the 30XW units
(including by container) the minimum and maximum permissible temperatures are
-20°C and 72°C (and 65°C for option 200).

Units with the medium temperature (option 5) or low
temperature (option 6) option allow glycol solution
production down to:
•
- 6°C with ethylene glycol and option 5 (minimum
weight concentration of 25%)
•
- 3°C with propylene glycol and option 5 (minimum
weight concentration of 24%)
•
- 12°C with ethylene glycol and option 6 (minimum
weight concentration of 35%)
•
- 8°C with propylene glycol and option 6 (minimum
weight concentration of 30%)
These options are available for the following unit reference
numbers:
30XW- P0512
30XW- P0562
30XW- P1012
30XW--1154
Option 100C (evaporator with one pass) is not compatible
with options 5 and 6. For option 5 the evaporator must be
configured with two passes and for option 6 with three passes.
