Air Source Heat Pump EAP range user manual - www.ecoairpump.co.uk
6.1. General Information
The following connections need to be made on the heat pump:
- supply/return lines of the heating system
- condensate drain
- control lead to the heat pump controller
- power supply
6.2. Heating-Side Connection
The connections on the heating side of the heat pump are provided with 1"external thread. The hoses to be connected exit the unit
through its side plate.
When carrying out the connections, use a wrench to counterhold at the transitions.
Before completing the heat pump connections on the heating water side, the heating installation must be flushed in order to remove
any impurities that may be present, residues of sealing agents, or the like. Any accumulation of residues and other deposits in the
condenser may result in reduced efficiency of the unit or a total failure of the heat pump. On systems equipped with heating water
flow shut-off devices such as radiator or thermostat valves, an overflow valve to be provided by the customer needs to be installed
at the outlet of the heating pump in a heating bypass. This assures a minimum heating water flow through the heat pump and
prevents any malfunctions from occurring.
Once the installation on the heating side has been completed, the heating system must be filled, deaerated and pressure-tested.
6.3. Anti-freeze Protection
On heat pumps installed in a location prone to frost, a manual drain valve should be provided.
Provided the controller and heating circulating pumps are ready for operation, the anti-freeze protection function of the controller is
active. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. In heat pump
installations where a power failure cannot be readily detected (holiday house), the heating circuit must contain a suitable antifreeze
product.
7. COMMISSIONING
7.1. General Information
To ensure proper commissioning it should be carried out by an after-sales service authorized by the manufacturer. Only then can
an extended warranty period of 2 years in total be granted.
7.2. Preparatory Steps
Prior to commissioning, the following items need to be checked:
- All connections of the heat pump must have been made.
- In the heating circuit all valves that could impair the proper heating water flow must be open.
- The air intake/discharge path must be unobstructed.
- The sense of rotation of the fan must correspond to the direction of the arrow.
- The settings of the heat pump controller must be adapted to the heating installation in accordance with the instructions contained
in its instruction manual.
- Proper condensate drainage must be ensured.
8. CLEANING / CARE
8.1. Care
To protect the paint finish, avoid placing objects against or on the unit. The external parts of the heat pump can be wiped with a
damp cloth and commercially available cleaning agents.
