Product Usage Instructions
Installation Advice
The document provides key information for correct installation from the Pre- Pipe stage to the Final Fit.
Condensate Management
- Ensure proper management of condensate to avoid slip hazards.
- Connect condensate to a drain using the supplied drain pan fitting.
Maximum Pipe Lengths
- Refer to the table for maximum pipe lengths based on the model and pipe diameter. Consider using an additional circulation pump for longer lengths.
Heat Pump Clearances
- Observe minimum clearances as per regulations. Mount the heat pump on anti-vibration mounting feet to allow airflow and prevent debris buildup.
Heat Pump Fitting KIT Assembly
- Assemble the fitting kit as per the provided diagram. Use appropriate thread sealing products for joints and ensure insulation of the fitting kit.
Electrical Connections and Supply
- Ensure correct electrical supply connections based on the model specifications. Use recommended cable sizes and fuse sizes.
FAQ
Q: What should I do before commissioning the Dual Clima HT?
A: Refer to the Domusa Commissioning Guide for assistance in completing the installation. Follow the provided instructions for commissioning.
Installation Advice
The purpose of this document is to highlight key information that is crucial to correct installation. Details, important to the Pre-Pipe stage through to Final Fit are included here.
Heat Pump Dimensions 12HT & 16HT
| Hydronic Port Size | 12HT | 16HT |
|---|---|---|
| Flow | 1” Male | 1¼” Male |
| Return | 1” Male | 1¼” Male |
| Drain | ½” Male | ½” Male |
| Hydronic Port Size | 12HT | 16HT |
| --- | --- | --- |
| Flow | 1” Male | 1¼” Male |
| Return | 1” Male | 1¼” Male |
| Drain | ½” Male | ½” Male |
Condensate Management
- This is an underside view of the heat pump condensate pan with dimensions for considerations around condensate management.
- Condensate can be piped to a drain such as a soak pit or free drain onto the concrete if a strip drain is being used around the Heat Pump.
- It is advised to make provisions to manage condensate as this can become a slip hazard when the condensate potentially freezes in winter.
- Connection to the heat pump can be made using the supplied drain pan fitting.
Maximum Pipe Lengths
- The table below details the maximum primary pipe length for both 12HT and 16HT when using 32mm Multitubo pipe directly to a buffer tank.
- This can be increased with the use of an additional circulation pump. Review system design or contact engineering for more information.
| Max Pipe Length – Flow + Return (m)
---|---
Diameter ⌀ (mm)| 12HT| 16HT
32| 44| 28
- If no buffer tank is used and the heat pump is directly feeding underfloor or radiators these values may be reduced depending on the system design.
- Again, this can be increased with the use of an additional circulation pump. Review system design or contact engineering for more information.
Heat Pump Clearances
- Basic minimum clearances CHNZ require to be observed. Certain installations with enclosed areas may require larger clearances. See the Installation manual for more details.
- It’s required that the heat pump be mounted on anti-vibration mounting feet, a minimum of 80mm off the ground.
- This will allow for correct airflow around the unit and prevent dirt and leaf debris from building up at the base of the finned heat exchanger.
- HPKANTVIBR allows each corner of the heat pump to be adjusted for installations on uneven ground and includes fasteners.
Heat Pump Fitting KIT Dimensions
Fitting KIT Assembly
- The image below details the basic assembly of the HPFIT16D Fitting KIT, including the integration of the FARDEAR1 FAR Deaerator.
- To achieve the dimensions stated on the previous page it is recommended that all fittings are threaded to the bottom threads where possible.
- CHNZ recommends using Loctite 55 thread cord, Hemp, Hawk White, or other thread-sealing products for these joints.
- Insulation of the fitting kit is required.
- Required primary pipe fitting size for flow assembly: 1’’ Recommended fitting: MT321MT
- Required primary pipe fitting size for return assembly: 1¼’’ Recommended fitting: MT32114MT
