1.5 General
Upon receive of the products,
1. Please ensure:
• The pipe ork should sho no signs of damage
• The fan/ fan motor terminals box is not cracked or sho ing signs of obvious damage
• The electrical scre terminals in control panels and motor mountings should be checked for security.
2. Product are only suitable for fix installation.
Product contains 4 bar±1bar holding charge (N2) hen despatched from factory, the holding gas should
be safely released through the schrader valve hich integrated on the suction gas inlet header.
3. If the holding charge is not present, please do not use the product and contact the sales representative
immediately. (Manufacturer’s arranty is void for damage caused by incorrect application or unit mis-
handling)
2 Health an Safety
2.1
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 eight
of the units.
Important Note:
Only a qualified refrigeration engineer, ho is familiar ith refrigeration systems and components
including all controls, should perform the installation and start-up of the system. To avoid potential
injury, use care hen orking around coil surfaces or sharp edges of metal cabinets. All piping and
electrical iring should be installed in accordance ith all applicable codes, ordinances and local by-
la s.

0-UC 13-FEB 18-2 Page 10
During Installation an subsequent maintenance
• Installation and maintenance are to be performed only by qualified personnel ho are familiar ith
local codes and regulations, and experienced ith this type of equipment.
• If lifting equipment is required, ensure that it is suitable for purpose, certificated and that the operatives
are qualified to use it.
• Safe orking methods are identified and operatives have suitable PPE.
• Ensure the orking area has adequate ventilation during brazing procedures.
• The units contain moving machinery and electrical po er hazards, hich may cause severe injury or
death. Disconnect and shut off po er 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 ork 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 hich the units ere intended
may be unsafe and be detrimental to the units, regardless of short or long-term operation.
• The units are not designed to ithstand loads or stresses from other equipment or personnel. Such
extraneous loads or stress may cause failure/leak/injury.

4 UNIT LOCATION AND MOUNTING
4.1 Unit Location
Unit coolers must be located at places that provide good air circulation; other ise the performances of the
unit cooler could be compromised. For best performance it is desirable to arrange the air discharge
blo ing to ard the door to minimize the entrance of arm moist air hen door is open. Light fixtures,
shelving and product boxes must be located in a manner hereby they do not block the air intake and air
discharge from the unit cooler.
Side clearance should be reserved so that service ork can be carried out.
IMPORTANT:
The coil face must be locate a minimum of 0.6xH” from walls to assure unrestricte air intake.
4.2
Mountin
Daikin unit coolers come ith mounting holes that can be fixed ith the use of M8 or M10 bolts and nuts.
The unit must be installed in a level manner, to ensure ater condensation can be properly drain out.

0-UC 13-FEB 18-2 Page 15
5 PIPING INSTALLATION
5.1 Refri erant pipe connection
Refrigerant pipe connections should be installed in accordance ith all the applicable codes and using good
refrigeration practices. Suction lines should be properly insulated to prevent s eating and ensure only
superheated vapor is returned to compressor suction. During brazing, the system should be purged ith
nitrogen first, to prevent oxidation.
5.2
Vacuum and leak test
When all refrigeration piping connections had been completed, the entire system must be tested for leaks
and then vacuum. Refer to the instruction manual provided by the coupled condensing unit for the leak test
and vacuum test information.
5.3
Drain pipe
Installing a trap is required for trouble free operation. If unit cooler is operated ithout the drain trap, arm
air ith higher temperature ill dra from outside to the cold room. Thus arm air ill significantly reduce
the cooler capacity and may lead to ice formation in the drain pan.
If the temperature surrounding the drain line and trap is belo freezing (0
o
C), it must be rapped ith a
drain line heater and insulation until out of all of the cool room. Be sure to rap the drain pan coupling
too.
Make sure the drain line is clear to prevent drain line plugged and overflo .
5.4 Superheat
Check suction superheat and adjust expansion valve to prevent liquid flood back to the compressor.
Recommended 5K to 20 K for suction superheat.
**Remarks: Expansion valve is not factory pre-fitted.

6.1 Field wirin
Field iring should comply ith local codes. The po er supply voltage, phase and frequency must
match hat is sho n on the unit cooler data plate.
The iring diagram for each unit is located on the inside of the panel door of the control box. The
unit must be grounded.

Units must be earthed and no maintenance ork should be attempted prior to disconnecting the electrical
supply. Installation of earth ire should be made to earth scre before connecting the live ires. The earth

WARNING
Please check electrical safety (leakage current, ithstand voltage, earth continuity) after connected
to heaters,

7 START UP
7.1 Pre-start up
After the installation is completed, a revie of the follo ing items should be performed before the
system is placed into operation:
Check electrical connections, fan motors, grills and all other fasteners for tightness. Be sure the
thermostatic expansion valve bulb is properly located, strapped and insulated.
With the system operating, check the supply voltage. It must be ithin +/- 10% of the voltage marked
on the unit nameplate.
7.2 Operation Checkout
A defrost cycle is needed hen the frost build up is such that is impedes the airflo through the coil.
The defrost requirements ill vary on each installation and may change depending on the time of the
year and other conditions.
Check the drain line and make sure drain line is clear and unit is aligned in all position to avoid
overflo of condensation ater.
8 PREVENTATIVE MAINTENANCE
A preventative maintenance schedule should be set up as soon as the Unit Cooler is installed. The unit
should be inspected periodically for proper operation and buildup of dirt.
1. Inspect and clean the drain pan to ensure there is no blockage. The drain pan should be
cleaned regularly ith arm ater and neutral detergent.
2. The cabinet, fans and guards can be cleaned ith ater and neutral detergent. Do not clean using
ater jet.
3. The evaporator coil should be checked once a month for proper defrosting. Many variables affect coil
frosting such as room temperature, type of product being stored, ho often ne product is brought in
and the length of time the door to the room remains open. Summer conditions of high humidity can
cause heavier frost loads. It may be necessary to change the numbers of defrost cycles seasonally.
4. At least every six months check all fan motors. Tighten motor mounting scre s and fan set scre s.
WARNING
Please be a are that during electric defrost; the temperature of surrounding may rise dramatically.
Ki
ndly keep
a safety distance a ay fro
m the unit.
