General Information
Important Note
Only a qualified refrigeration engineer who is familiar
with refrigeration systems and components, including all
controls should perform the installation and start-up 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.
This appliances is not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsible for their safety. Children should be
supervised to ensure tha
t they do not play with the
appliance.
Ensure the unit received is the correct model for the intended
application.
Ensure refrigerant, voltage, are suitable for the proposed
application and environment.
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 nitrogen holding charge.

REFRIGERATION
CONDENSING UNIT
The condensing unit contains moving machinery and electrical
power hazards. May cause severe injury or death.
Disconnectand shut off power before installation or service of
the equipment.
Refrigerant release into the atmosphere is illegal. Proper
evacuation, handling and leak testing procedures must be
observed at all times.
Condensing unit must be earthed
Improper earthing may result in electric shocks
or fire.
Be sure to switch off the unit before
touching any electrical parts. Touching a live part may result in
electric shocks or fire.
The electrical covers and condenser fan guard must remain
fitted at all times.
Use of the condensing unit outside of design conditions and
application for which units were intended may be unsafe and be
detrimental to the unit, regardless 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) component
may be required, it offers protection against refrigerant flood
back during operation. It helps protect against off-cycle
migration by adding internal free volume to the low side of the
system.
Test 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. For unit Series 1 JEHCCU040CM1
and JEHCCU0050CM1, it is advisable to connect with
thermostat cut off configuration using the reserved terminal in
control box.
After installation, the system should be allowed to run for 3 – 4
hours. The oil level should be checked after 3 – 4 hours run time
and topped up as necessary. The oil level should not be lower
than quarter of the compressor oil sight glass.
3.1 Unit site location
In order to achieve maximum cooling capacity, the installation
location for condensing unit should be carefully selected.
Install the condensing unitin such a way so that hot air
distributed by the condensing unit cannot be drawn in again (as
in the case of short circuit of hot discharge air). Allow sufficient
space for maintenance around the unit.
Ensure that there is no obstruction of air flow into or out of the
unit. Remove obstacles which block air intake or discharge.
