1. SAFETY INSTRUCTIONS
1.1 Safety isolating switch/Main switch
The connection hood for RX/HC 011-020 is placed on top
of the air handling unit to the right or left of the GOLD air
handling unit’s connection hood (above the rotating heat
exchanger), see illustration. The safety isolating switch is
located on the side of the connection hood for RX/HC size
011-020.
For size 025-080, the safety isolating switch is located on
the air handling unit’s inspection side to the right or left
of the GOLD air handling unit’s safety isolating switch (in
front of rotating heat exchanger), see illustration.
The safety switch should not be used to start or stop of
the reversible heat pump.
Ensure that the RX/HC is shut off by stopping the air han-
dling unit or by temporarily shutting off the RX/HC via the
hand-held micro terminal, see the GOLD operation and
maintenance instructions.
When this has been carried out, the current can be iso-
lated with the safety switch. The safety switch must be
switched off in order to make it possible to open the
inspection door.

Important:
Always switch off the safety isolating switch before ser-
vicing the unit if not otherwise specified in the pertinent
instructions.
Warning
The inspection doors must not be opened when air han-
dling unit is operational. The doors can open and injure
personnel.
1.3 Electrical equipment
Housed on the inside of an inspection door to the right or
left of the rotating heat exchanger is electrical equipment
for RX/HC mounted in a separate electrical equipment
cubicle.
1.4 Authorisation
Only authorized electricians shall be permitted to install
electrical wiring in the unit.
Only an accredited refrigeration company shall be permit-
ted to modify or repair the refrigeration circuit.
Other service work in the unit should only be performed
by service personnel trained by Swegon.
1.5 Decals
The type number mark with type designation, serial num-
ber, refrigerant volume and more is affixed on the chiller’s
door.
1.2 Risks
Warning
Under no circumstances may the refrigerant circuit be
opened by unauthorised personnel, since it contains gas
under high pressure.
Warning
Before carrying out any work, make sure that the power
supply to the air handling unit has been switched off.
Risk areas for refrigerant
Risk area for refrigerant is in principal inside the entire
reversible heat pump. For handling when leakage, see
section 7.2.
The refrigerant used is R410A.

Refrigerant
Type R410A refrigerant is used. The refrigerant circuits are
charged with refrigerant on delivery. At present, this re-
frigerant has no known influence on the ozone layer and
no known future restrictions are anticipated.
Refrigerant volume
See section 10. General technical data.
Installation check/Obligation to report/
Leakage tracing interval
Must be carried out according to the F-Gas Regulation
EU/517/2014 and associated local legislation.
Quality System to ISO 9001
and Environmental Management System to ISO
14001
Swegon AB works to a certified quality system that con-
forms to ISO 9001 standard and a certified Environmental
Management System that conforms to ISO 14001.
2. OVERVIEW
2.1 General
General
RX/HC is a complete reversible heat pump, fully inte-
grated in the GOLD air handling unit.
RX/HC consists of one section with sorption rotor and
one section on each side of this that contains heating/
cooling engineering components.
All components from a cooling and electrical standpoint
are pre-wired.
The casing is composed of cover panels and inspection
doors. The outer skin is made of galvanized sheet steel,
pre-painted in Swegon’s grey metallic colour (closest com-
parable: RAL, 9007). The inner skin is made of aluminium-
zinc plated sheet steel. Environmental Class C4. Panel
thickness of 52 mm with intervening insulation consisting
of mineral wool.
The evaporator and condenser consist of copper tubes
and profiled aluminium fins.
RX/HC is test run prior to delivery.
RX/HC is available in 6 physical sizes, designed for GOLD
air handling units in size 011-080.
RX/HC are designed and tested for ambient temperatures
from -40°C to +40°C. The heat pump function withstands
temperatures from -25°C to +35°C.
Compressors
The refrigerant circuit contains a variable speed controlled
compressor (all sizes) that regulates the output. Size 040-
080 also comprises an on/off compressor for increased
capacity.
Completely direct-acting system
The RX/HC has a completely direct-acting system. It has an
evaporation coil for direct-evaporating refrigerant on the
cold side and a condenser coil on the hot side.
