High-efficiency air-to-water heat pump
Max. flow temperature 58 °C
Casing colour White aluminium (similar to RAL 9006)
High-efficiency air-to-water heat pump
With two performance levels
LA 17TU
LA 40TU
Heat pump for heating purposes for outdoor installation, with wall-mounted WPM EconPlus heat pump manager and two compressors
for output reduction when operating at partial load. Sound-optimised through the use of slow-running “owl‘s wing” ventilators with
a low natural sounding noise, an encapsulated compressor housing with free-swinging compressor baseplate for solid-borne sound
insulation. High coefficients of performance (COP) through high-performance evaporator and compliance with the requirements of
EN 14511 for larger volume flows on the heat consumption side. High operational safety through sensor monitoring of the refrigeration
circuit for energy-efficient defrosting; integrated thermal energy metering (display of the thermal energy volume for heating and
domestic hot water preparation on the WPM EconPlus heat pump manager). Access for service work on the outlet side; the minimum
clearances must be observed for installation close to walls. Universal design with two compressors for modulating operation, optional
domestic hot water preparation and flexible expansion options for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Soft starter, integrated flow and return sensors; external sensor (standard NTC-2) included in the scope of supply.
Electrical connection cable EVL . . U between heat pump and heat pump manager must be ordered separately.

Heat output and COP according to EN 14511 at A2/W35.
The air outlet must be positioned at a right angle to the main wind direction if unsheltered outdoor installation is carried out.
If this is not possible, a weather-proof protective cover must be installed!

High-efficiency air-to-water heat pump
With two performance levels
LA 60TU
Heat pump for heating purposes for outdoor installation, with wall-mounted WPM EconPlus heat pump manager and two compressors
for output reduction when operating at partial load. Sound-optimised through the use of two slow-running EC-3D fans, an encapsulated
compressor housing and a free-swinging compressor baseplate for solid-borne sound insulation. High coefficients of performance (COP)
through high-performance evaporator, electronic expansion valve and compliance with the requirements of EN 14511 for larger volume
flows on the heat consumption side. High operational safety through sensor monitoring of the refrigeration circuit for energy-efficient
defrosting; integrated thermal energy metering (display of the thermal energy volume for heating and domestic hot water preparation
on the WPM EconPlus heat pump manager). Access for service work on the outlet side; the minimum clearances must be observed for
installation close to walls. Can be easily transported with a lift truck (accessible from underneath) or lifting lugs. Universal design with
two compressors for modulating operation, optional domestic hot water preparation and flexible expansion options for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
At an external temperature of -10 °C, the maximum flow temperature that can be achieved is 60 °C. Soft starter, integrated flow and
return sensors; external sensor (standard NTC-2) included in the scope of supply.
Electrical connection cable EVL . . UE between heat pump and heat pump manager must be ordered separately.

Heat output and COP according to EN 14511 at A2/W35.
The flow temperatures that can be achieved depending on the heat source temperature can be derived from the operating limits diagram.
Note:
Dimplex heat pumps for heating purposes are designed for use in a domestic environment and conform to the low voltage directive.
They are thus also intended for use by non-professionals for heating shops, offices, hotels and other similar working environments, in agricultural
establishments and other residential buildings. The LA 60TU and SI 130TE heat pumps can be supplied, according to the machinery directive with
an external switch box upon request (order reference: LA 60TU-MD, SI 130TE-MD).
