The Complete System
CTCEcoAir510M
CTC EcoAir 510M is a modulating air source heat pump
that takes heat from the outside air and supplies it to the
existing heating system in the house. The heat pump
works with outdoor temperatures down to -22°C.
CTC EcoAir 510M is designed to operate with high
efficiency and low noise levels. The heat pump has
integrated discharge defrosting which keeps the
evaporator coil free from ice to maintain high efficiency.
EcoDesign information relating to the current
combination (current package) can be downloaded from
www.ctc.se/ecodesign. Energy labelling stickers can
also be printed from here.
Control
CTCEcoAir510M is controlled by these products:
• CTCEcoZenithi555/i550 PRO
• CTCEcoLogicM/L/PRO/Family
• CTCEcoZenithi255/i250
• CTCEcoZenithi360/i350
• CTC EcoVenti360F/i350F
Charge pumps
CTC’s PWM-controlled charge pumps are available
as accessories for CTCEcoZenithi555/i550 PRO and
CTCEcoLogicM/L/PRO/Family.

1. Important to remember!
Check the following points in particular at the time of delivery and installation:
1.1 Transportation
• Transport the heat pump to the installation location
before removing the packaging. Move the product
using one of the following means:
- Forklift
- Lifting band around the pallet. NB: Can only be
used with the packaging on.
• The heat pump must be transported and stored
upright.
1.2 Positioning
• The heat pump must be transported and stored
upright.
• Remove the packaging and check before
installation that the product has not been damaged
in transit. Report any transport damage to the
carrier.
• Place the product on a solid foundation, preferably
concrete.
If the heat pump needs to be placed on a soft
carpet, base plates must be placed under the
adjustable feet.
• Remember to leave an access and service area of
at least 1 metre in front of the heat pump.
• The heat pump must not be placed below floor
level.
• Avoid placing the heat pump in rooms where
the walls are of lightweight design, as people
in the adjoining room may be disturbed by the
compressor and vibrations.
1.3 Recycling
• The packaging must be deposited at a recycling
station or with the installation engineer for correct
waste management.
• Obsolete products must be disposed of correctly
and transported to a waste station or distributor/
retailer offering this service.
Disposal of the product as household waste is not
permitted.
• It is very important that the product’s refrigerant,
compressor oil and electric/electronic components
are disposed of correctly.
1.4 After commissioning
• The installation engineer advises the property
owner on the design and servicing of the system.
• The installation engineer fills in a checklist and
contact information – the customer and installation
engineer sign the list, which the customer keeps.
• Make sure to register your product for warranty
and insurance via the CTC website:
https://www.ctc-heating.com/customer-
