INSTALLATION
This option kit includes a hot water coil with two attachment
profiles for coil to the unit.
Make sure to install the hot water coil to the aspiration of
the unit, then:
• Dismount the air filter attachment.
• Fix the attachment profiles with screws to the
aspiration.
• Fix the hot water coil to the attachment profiles.
• Put the air filter again across the profiles.
COMPRESSOR ACOUSTIC JACKET
Each compressor is fitted with a compressor acoustic jacket this provides attenuation of the compressor noise that radiates
from the unit when in operation.
THREE PHASE PROTECTION (THREE PHASE UNITS)
Located at the electrical box of the unit, it assures that unit will not begin operation if connection phases of compressor are
not correct. Should this occur, then just switch two phase connections.
