1 Important information/Safety regulations
 
These instructions are a UK-specific appendix to those instructions found in the Installation instructions.
 
Read the Installation instructions prior to installation.
 
For DHP Opti Pro SP (Single Phase) heat pumps it is imperative that the maximum hot water temperature
is altered from the default factory setting from 95°C to 60°C. Refer to Chapter 9.8 menu Service – HGW
Parameter MAX TEMP in Installation instructions.
 
Hard Water Areas; Normally it is not a problem to install a heat pump in hard water areas since the normal
domestic hot water working temperature will be not greater than 60°C. In areas where exceptional water
conditions prevail, consideration may need to be given to the fitting of a device capable of inhibiting scale.
In such circumstances the advice of the local water authority should be sought.
 
The immersion heater, thermostat, and thermal cut-out are supplied by Danfoss and are factory fitted. If a
replacement part is necessary, it must be replaced with a Danfoss spare part.
 
The water heater is protected with a sacrificial aluminium anode. Under normal circumstances no mainte-
nance is needed.
 
Note! Leave the following documents with the end-user;
- This manual
- Installation instructions
- User manual
The above documents are an integral and essential part of the product. They should be kept with the appli-
ance so that they can be consulted by the user and our authorised personnel.
Please read carefully the instructions and notices about the appliance contained in this manual, as they pro-
vide important information regarding the safe installation, use and maintenance of the heat pump.
1.1 Test results
1.1.1 Heat up time
The heat up time is measured when heating the water from 14°C to 60°C.
DWH 300: Heat up time 1 hour 53 minutes
DHP-H, DHP-A, DHP-AQ Maxi and DWH 200: Heat up time 1 hour 3 minutes
1.1.2 Re-heat time
The re-heat time is measured when 70% of the hot water has been drained and replaced by equal amount
14°C water and re-heated to 60°C.
DWH 300: Re-heat times 70% 1 hour 25 minutes
DHP-H, DHP-A and DWH 200: Re-heat time 70% 41 minutes
DHP-AQ Maxi: 1 hour 6 minutes according to EN12897.
1.1.3 Pressure drop
The measured pressure drop throgh the primary heater is 15 kPa.
1.1.4 Hot water capacity
DHP-AQ Maxi: 160 liter according to EN12897.

4 Commissioning
4.1 How to flush the tap water system
When the tap water and the heating system have been filled up, the unit shall be running at maximal, nor-
mal operating temperature for a minimum of one hour. After that the tap water system shall be flushed out
and re-filled.
4.2 How to drain the tap water system
After the tap water system has been flushed out, the cold and hot water pipes and the water heater tank
need to be drained. To drain the system follow the instructions below:
1. Close the shut-off valve on the incoming water supply.
2. Open both cold and hot water taps which are situated as low as possible in the building to depressu-
rise the system.
 
Please note that there can be some water remaining in the cold water pipe which must be taken care of
when loosening the pipe.
3. Loosen and remove the cold water pipe at the top of the heat pump.
4. Insert a plastic hose to use as a siphon into the cold water connection and bring it to the bottom of
the water heater tank.
5. Place the other end of the hose near a gully.
6. Use the siphon effect to empty the water heater tank.
 
For location and dimension of connections, please see chapter 4.1 in the Installation Instructions.
4.3 Inspection access
The hot water tapping connection can be used as an inspection access.
