将控制器放到开孔中，轻轻按下侧面的卡扣，然后是前盖板，直到
控制器完全插入(侧面卡扣将弯曲，卡钩将控制器固定在面板上)。重
要：前盖板防护等级
IP65仅当下列条件满足后才能达到：
• 矩形开孔与水平面最大偏差：≤ 0,5 mm；
• 电控板金属片厚度：0.8 …2 mm；
• 应用垫圈的表面的粗糙度：≤ 120 μm。
注意：用于制造电控板的金属片厚度(或材料)必须足够确保安全和稳
定的安装产品。
Place the controller in the opening, press lightly on the side tabs and then on the front until fully inserted
(the side tabs will bend, and the catches will attach the controller to the panel). Important: IP65 front pro-
tection is guaranteed only if the following conditions are met:
•
maximum deviation of the rectangular opening from at surface: ≤ 0.5 mm;
•
thickness of the electrical panel sheet metal: 0.8-2 mm;
•
maximum roughness of the surface where the gasket is applied: ≤ 120 μm.
Note: the thickness of the sheet metal (or material) used to make the electrical panel must be adequate to
ensure safe and stable mounting of the product.

Important: during the rst connection, Applica aligns itself with the soft-
ware version on the µChiller controller via a cloud connection; this means a
mobile data connection is needed at least for this rst connection.

COMMISSIONING
The procedure for initial commissioning is described below.
PREPARATION
Before conguring the unit the rst time, access KSA (ksa.carel.com), select
the “Congurations” folder and:
1. for the Chiller Standard and Enhanced models (with On/O compressor)
select the “Refrigerants” section and then the refrigerant charged in the unit;
2. for HE models (with BLDC compressor), import the BLDC conguration, se-
lecting the “BLDC compressors” section and then the brand and model of
compressor installed on the unit (this already includes the refrigerant setting)
3. import the downloaded conguration into the mobile device.
CONFIGURATION
1. start Applica and access the Manufacturer and Service proles;
2. select Set-up -> Conguration and click the + icon (see image)
3. use the menu (Fig. a) to select and apply the desired conguration;
4. select Unit Set-up (Fig. b) to proceed with the complete conguration (Fig c).
