Service menu. Warning! Danfoss SP (1-phase) heat pumps have a factory installed safety valve for temperature and pressure, (10 bar 90-95°C), in accordance with the requirements in Great Britain. This valve is located in the water tank and may not be used for any purpose other than connecting the outlet pipe. -
Page 9: Refrigerant
Caution! The hot water tank must be equipped with an approved safety valve. Caution! Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safety valves. Caution! Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corrosion-resistant material, e.g. -
Page 10: Electrical Connection
Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer’s plate) through the service valves. Caution! All warranties from Danfoss are void if, when filling with refrigerant other than Danfoss A/S specified refrigerant, if there has not been written notification that the new refrigerant is an approved replacement refrigerant together with other remedies. - Page 11 Caution! If the installation is only to be driven by an auxiliary heater during the installation, ensure that the heating system is filled and the brine pump and compressor cannot be started. This is carried out by setting the operating mode to AUX. HEATER. Installation instructions VMBMA1002 –...

Page 17: Transport, Unpacking And Setting-Up
Transport, unpacking and setting-up Transporting the heat pump Caution! During transportation or lifting of the entire heat pump, the front panel must always be installed as it locks the other panels construction. Caution! The heat pump must always be transported and stored in a dry area. Secure the heat pump so that it cannot tip over during transportation. - Page 18 Avoid positioning the heat pump in a corner as the surrounding walls may amplify its noise. It is also important to adjust the heat pump using the adjustable feet so that it is horizontal to the base. 4.3.2 Space requirement Caution! The heat pump must not be enclosed as the temperature inside the cabinet becomes extremely high.

Press against the front cover and turn the catch 90° degrees anti-clockwise to release the front cover. Tilt the front cover outwards. Lift the front cover upwards to remove it from the heat pump. Setting-up the outdoor unit Note! Applies to DHP-A. 4.4.1 Recommended location When positioning the outdoor unit, note the following: Caution! When the outdoor unit is defrosting, water will drip straight down under the unit. - Page 20 4.4.2 Space requirement 300 mm 300 mm 300 mm 1500 mm Figure 9. Necessary service space for outdoor unit. 4.4.3 Unpacking The outdoor unit is packed and delivered in a crate. Start by unpacking the unit from the crate. Check that the delivery is complete, it must contain the outdoor unit, front cover, cover as well as a disas- sembled stand including necessary screws, nuts and washers.
- Page 21 There are three M6x20 screws on the lower edge of the outdoor unit. Unscrew them so that 2-3 mm of the thread remains. Use a torx TX25 screwdriver, or equivalent. Caution! Do not lift the outdoor unit by its side panels when it is to be raised or moved. Raise the outdoor unit.
- Page 22 Secure the front panel's upper edge with the 2 x remaining M6x15 torx TX25, see figure below. Figure 12. Secure the cover 4.4.4.6 Install the cover Hook the cover at the front edge on the front cover. Figure 13. Hook the front cover into place Secure the cover using a screw on each side.

Route the pipe for brine out through the corresponding hole (with rubber collar) in the heat pump side. Caution! When the brine lines are connected to the right for DHP-A, the brine out line must be routed over the brine pump, under the compressor’s vacuum pipe and under the condenser’s flexible hose, see figure below. -
Page 38: Noise Information
The brine pipes running outside the house to the collector can be buried, however they must be well insulated. Caution! Applies to DHP-A:Bear in mind that the outdoor unit may move during defrosts, use flexible hoses to connect the pipes from the heat pump and pipes on the outdoor unit. - Page 39 used for all pipe connections to avoid the transmission of vibrations. Flexible hoses are available to purchase as accessories. The figures below show how appropriate and inappropriate installations look using this type of hose. To avoid noise caused by pipe mounting, a rubber-coated pipe clamp should be used to prevent the transmission of vibrations.
