ACF60-00 – Installation, User’s and Maintenance Manual
42 Ed. 04/2012
Ground installation
Place the ACF on a flat, level surface (support base) made of fireproof material.
If a horizontal support base is not available, a flat and level base made of cement must be
made that is slightly larger than the base of the ACF: at least 100-150 mm per side; the
dimensions of the ACF are reported in the “TECHNICAL SPECIFICATIONS” paragraph
on page 11.
Roof or terrace installation
Place the ACF on a flat, level surface (support base) made of fireproof material.
The ACF must rest upon a base that can support its weight (the weight of the ACF is
reported in paragraph 1.4 TECHNICAL SPECIFICATIONS, page 11). The building
structure must be able to support the weight of the ACF along with the weight of the
support base.
If necessary, a gangway can be made around the ACF for future maintenance
interventions.
Avoid installing the ACF in quiet areas or in areas where silence is requested.
Even though the ACF only creates modest vibrations, the use of anti-vibration brackets
(available as an accessory, see “ACCESSORIES” on page 81) is especially
recommended in all cases where reverberations are confirmed, such as on rooftops or on
a terrace; use flexible connections (anti-vibrational connectors) between the machine and
the water and gas piping.
Supports and levelling
The ACF must be correctly levelled. This is checked by placing a level on the upper part
of the machine.
If necessary, metal shims can be placed in the appropriate positions below the ACF until it
is level; do not use wood shims, as they degrade quickly.
3.3 WATER CONNECTIONS
General instructions
• The water system piping can be made of stainless steel, black steel, copper or cross
linked polyethylene suitable for air conditioning and refrigeration systems. All the
water tubing and connections must be heat insulated in accordance with current
regulations, to avoid the dispersion of heat and the forming of condensation.
• To prevent the water from freezing during the winter, glycol should be used as an
antifreeze (see Table 22 on page 49). DO NOT USE glycol in galvanized tubing,
which will cause corrosion in the presence of glycol.
• Use a minimum amount of 10% glycol antifreeze to also prevent ice from forming in
the evaporator during normal summertime operation of the ACF.
• If using rigid tubing, flexible connections should be used for the intake and delivery of
chiller water to prevent the transmission of vibrations (see “ACCESSORIES”, page
81).
