User manual HONEYWELL TOE 0.5-4.5 INSTALLATION

[. . . ] Obligatory for multiple injection by liquid distributors. · Combi adsorber charge as standard The same valve can be used for different refrigerants (see table on page 2) Controller charge is high sensitive and responsive thus lowest possible level of superheat can be achieved TOE 0. 5-4. 5 0. 5-4. 5X 0. 5 - 4. 5 two-way Charge is not sensitive to effects of temperature on the capillary tube and valve head damping characteristic results in stable control behaviour · Optional available with gas charge and MOP · Adjustable superheat for two-way construction · Fixed superheat setting for angle construction TOE 0. 5-4. 5 0. 5-4. 5X 0. 5 - 4. 5 angle · Warm thermal head provides best reliability · O-ring connections · Extreme durable due to stainless steel head and stainless steel diaphragm welded using protective gas · Fixed orifice · Refrigerants: R134a R22, R407C, R422D R404A, R507A Further refrigerants on request. Application Thermostatic expansion valves series TOE 0. 5-4. 5 0. 5-4. 5(X) are used in plants with one or more refrigerant circuits, especially for series installations, mobile air-conditioning and cooling units with O-ring connection, e.

Thermal systems with adsorber charge are completely insensitive to effects of temperature on the capillary tube and valve head. It reacts only according to the temperature of the bulb. Thus, Honeywell TOE 0. 5-4. 5 0. 5-4. 5(X) valves with combi adsorber charge work absolutely reliable, even in icy condition or while defrosting using hot gas. · Do not bend or squeeze the bulb when tightening the bulb clamp!· Constructive modifications at the valve are not allowed. Information for original equipment manufacturers: The valve series TOE 0. 5-4. 5 0. 5-4. 5 can be customised to the requirements of your series device in an optimum way. Contact us! Superheat Adjustment (Two-way Valve) In general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered. This superheat adjustment is calibrated for lowest superheating and optimum evaporator utilisation. However, should it be necessary to adjust the superheat, turn the adjusting spindle as follows: Turning clockwise Turning counterclockwise = = reduced refrigerant mass flow, increase of superheat increased refrigerant mass flow, decrease of superheat One turn of adjusting spindle alters superheat setting by approx. Increase of superheat setting results in a lower MOP-value and vice versa.
