2. Standard Product Configuration
•Reliable reciprocating type compressor for medium and low temperature models with oil sight glass
•IP54 rated control panel
•Magnetic contactor (Note: except single phase medium temperature application condensing unit).
•External shut off valves for quick installation and easy access and maintenance.
•Weather proof housing made of epoxy coated steel
•Corrugated aluminium fin and inner groove hairpin condenser
•Liquid receiver is sized to accumulate refrigerant amount up to 25m piping length during pump down.
Fusible plug on the liquid receiver to protect system from exploded when ambient temperature goes
higher than 1000C
•Oil separator and non-return valve for low temperature models
•Sight glass and flare type filter drier
•Dual pressure switch to protect compressor
•Designed for zero ozone depletion potential (ODP=0) refrigerant R404A (available for all range
condensing units) or R134a (available for medium temperature application condensing units).
•The condensing unit is fully factory tested and is filled with nitrogen in order to always ensure the
highest quality of our products.

8. Safety and Health
General Information
Before Installation
•Ensure the units received are the correct models for the intended application.
•Ensure the refrigerant, voltage and MWP are all suitable for the proposed application.
•Check there is no damage to the units. Any damage should be advised to the supplier immediately.
•Check that the proposed equipment locations are suitable and provide adequate support for the
weight of the units.
During Installation and subsequent maintenance
•Installation and maintenance are to be performed only by qualified personnel who are familiar with
local codes and regulations, and experienced with this type of equipment.
•The condensing unit is delivered with a protective nitrogen holding charge.
•If lifting equipment is required, ensure that it is suitable for purpose, certificated and that the
operatives are qualified to use it.
•Safe working methods are identified and operatives have suitable Personal Protective Equipment
(PPE).
•Ensure the working area has adequate ventilation during brazing procedures.
•The units contain moving machinery and electrical power hazards, which may cause severe injury
or death. Disconnect and shut off power before installation or service of the equipment.
•Refrigerant release into the atmosphere is illegal. Proper evacuation, recovery, handling and leak
testing procedures must be observed at all times.
•Units must be earthed and no maintenance work should be attempted prior to disconnecting the
electrical supply.
•The electrical covers and fan guards must remain fitted at all times.
•Use of the units outside of the design conditions and the application for which the units were
intended may be unsafe and be detrimental to the units, regardless of short or long term operation.
•The condensing units are not designed to withstand loads or stresses from other equipment or
personnel. Such extraneous loads or stress may cause failure/leak/injury.
•In some circumstances, a suction accumulator (not supplied) may be required. It offers protection
against refrigerant flood back during operation and also against off-cycle migration by adding
internal free volume to the low side of the system.
•Tests must be conducted to ensure the amount of off-cycle migration to the compressor does not
exceed the compressor’s charge limit.
•Wherever possible the system should be installed to utilize a pump down configuration.
•After installation, the system should be allowed to run for 3 –4 hours. Additional oil should be
added as necessary depending on length of pipe run. It should then be rechecked after 24 hours
once the system has stabilized. For details of the oil requirements, please refer to page 28 in the
service and maintenance section.
Important Note
Only qualified specialists could carry out the installation, maintenance and
commissioning of the system. To avoid potential injury, use care when working
around coil surfaces or sharp edges of metal cabinets. All piping and electrical
wiring should be installed in accordance with all applicable codes, ordinances and
local by-laws.

9. Installation & Commissioning
9.1 Unit site location
•In order to achieve maximum cooling capacity, the installation location for the condensing unit should be
carefully selected.
•Install the condensing unit in such a way so that hot air ejected by the condensing unit cannot be drawn in
again (short circuit of hot discharge air). Allow sufficient space for maintenance around the unit.
•Ensure that there is no obstruction to air flow into or out of the unit. Remove obstacles which block air intake
or discharge.
•The location must be well ventilated, so the unit can draw in and distribute plenty of air thus lowering the
condensing temperature.
•To optimize the unit running conditions, the condenser coil must be cleaned at regular intervals.
•The unit must be level in all directions.
