Important safety notice
Before working with the manifold, please read the instruction manual carefully. This manual provides important information regarding the smooth operation, maintenance and disposal of the manifold.
Purpose and use
The manifold has been developed for measuring and adjusting pressure and temperature in both mobile and stationary refrigeration equipment.
The manifold must not be used for anything other than the above-stated purposes.
The manifold must not be used with pressures higher than 60bar / 870psi / 6000kPa / 6MPa.
Under no circumstances should the manifold be used as a pressure regulator, especially not when using nitrogen N2.
The manifold must not be used with the refrigerant ammonia (NH3 / R717).
The manifold should not be exposed to rain or used in damp or wet environments.
Protective goggles and gloves must always be worn when using the manifold.
REFCO products have been specially designed and manufactured for use by trained refrigeration and air-conditioning service engineers only. Due to the high pressures and the physical and chemical gases used in refrigeration systems, REFCO cannot be held liable or responsible for any accidents, injuries or deaths arising during use of the manifold. REFCO explicitly states that their products must only be sold to professionally trained experts.

Scope of delivery
Information about the various models and variations of our products can be found in the REFCO catalogue or at www.refcoswiss.com
Transport
The manifolds are delivered from the factory in a plastic box, with or without filling hoses. Manifolds are high-grade instruments and should always be transported and stored in a box.
Important note:
Remove refrigerants from the manifold and the hoses after use.
The hose connectors hanging freely from the manifold (screw joints / system side) can be screwed onto the Y-connectors and to the central T-piece, when not in use. This serves to protect the thread from contamination and damage.
Technical description
The DIGIMON can be used with the following refrigerants:
R11, R113, R114, R12, R123, R124, R13, R134a, R13B1, R22, R227, R23, R290, R32 R401A(Liq), R401A(Vap), R401B(Liq), R401B(Vap), R402A(Liq), R402A(Vap), R402B(Liq), R402B(Vap), R403B(Liq), R403B(Vap), R404A, R406A (Liq), R406A(Vap), R407A(Liq), R407A(Vap), R407C(Liq), R407C(Vap), R407F(Liq), R407F(Vap), R408A(Liq), R408A(Vap), R409A(Liq), R409A(Vap), R410A, R413A(Liq), R413A(Vap), R414B(Liq), R414B(Vap), R416A, R417A(Liq), R417A(Vap), R420A, R422A(Liq), R422A(Vap), R422B(Liq), R422B(Vap), R422C(Liq), R422C(Vap), R422D(Liq), R422D(Vap), R427A(Liq), R427A(Vap), R437A, R438A(Liq), R438A(Vap), R500, R502, R503, R507, R508A, R508B, R600A, R744, R1234yf

Filling the system
a)with DIGIMON-SE manifold
Disconnect the yellow hose from the vacuum pump and screw it onto the refrigerant bottle or cylinder.
Open the valve on the refrigerant bottle or cylinder.
Open the blue valve (5) (low pressure side) and let the required amount of refrigerant to flow in. If the required amount of refrigerant does not flow into the system, the compressor must be switched on.
After the system has been filled with the desired amount, close the valve on the refrigerant bottle or cylinder.
Close the blue valve (5).
Check the system's pressure and temperature!
Remove the hoses from the system.
Open valves (5+6).
b)with DIGIMON4 manifold
Disconnect the yellow hose (3/8“) from the vacuum pump and the DIGIMON4
(3)and screw the caps onto the 3/8“ SAE thread.
Open the black valve (8).
Open the valve on the refrigerant bottle or cylinder. Then open the blue valve
(5)and allow the required amount of refrigerant to flow in. If the required amount of refrigerant does not flow into the system, the compressor must be switched on.
After the system has been filled with the desired amount, close the black valve (8).
Close the valve on the refrigerant bottle or cylinder.
Open the red valve (6). Check the pressure and temperature on the high and low pressure sides of the system! If all pressures are in order, close all valves.
Remove the hoses from the system.
Open all valves.

Measuring using the Superheat / Subcool modes
See section "Connecting the DIGIMON manifold".
Plug the K-Type plug of the external thermocouples (9) or the clamp thermocouple (10) into the DIGIMON (sockets on the right (t1) and left (t2) side of the housing).
Fix the external thermocouple (9) or the clamp thermocouple (10) with adhesive tape to the required measuring point on the high pressure or suction pressure side of the system.
Set the appropriate refrigerant (see section "Select refrigerant").
Switch on the temperature difference display: press SUPERHEAT/ SUBCOOL.
Maintenance work on the manifold
A visual inspection of the connections and filling hoses must be carried out before each use, to check for mechanical damage.
Do not use aggressive cleaning agents or solvents to clean the device. Gentle household cleaners and soapy water should be used instead.
Manifold seals are subject to mechanical and age-related wear. Therefore, the manifold should be regularly tested by the user for leaks.
In case of leaky valves, the piston should be replaced (M4-6-04-R/10).
The special REFCO M4-6-11-T tool should be used to change the sight glass on the manifold.
The manifold should be checked after the replacement of seals to ensure there are no leaks.
