Important
m Read this manual carefully and familiarise yourself with the specifications and
operation of REFCO manifolds prior to use. These instructions provide important
information regarding the operation and service of this manifold.

Purpose and use:

The manifolds have been designed especially to measure pressure in refrigeration equip-
ment. For use only by trained technicians.
m The manifold must not be used for anything other than refrigeration applications in
connection with refrigerants. The manifold is not suitable for liquids or gases other
than those indicated on the gauge.
m The manifold must not be used with pressures higher than the pressure scale indica-
ted on the high pressure gauge of the manifold.
m The manifold cannot be used as a pressure regulator, especially not in use with nitro-
gen N .

m The manifold cannot be used with ammonia (NH
m Safety goggles and gloves must be worn during the use of the manifold.
m REFCO-products are designed and manufactured for use by technically trained air
conditioning and refrigeration service engineers only. Due to the high pressures, and
the physical and chemical nature of refrigerants and oils used in the systems, incor-
rect application could result in serious accidents, injuries or death.

Extent of delivery:

Details about the variations and contents of the manifold are described in the REFCO
catalogue as well as on the web www.refco.ch.
Storage:
Manifolds are high precision measuring instruments. After use store the manifold in a
protected environment.
Note: Do not store the manifold with refrigerant in the unit or hoses.

Technical description:

The 4-way manifold is a high precision instrument. Both gauges, high and low pressure
can be readjusted to the zero point. The manifold gauges are marked with temperature
and pressure scales or are equipped with interchangeable refrigerant scales.
