(8) Remote Ice Queen Machine Installation: Connect to the Field-Installed Condensing Unit
Connect the pipes of a field-installed condensing unit (or a field-installed condenser located remote from the ice maker)
to the connections valves of the machine: the high pressure (liquid) line to the inlet connection valve (3/8" SAE) and the
low pressure (suction) line to the outlet connection valve (1/2" SAE).
Make vacuum to lines. Use allen wrench to open liquid and suction line connection valves. Unit is precharged with R404A
till positive pressure.
Connect the low pressure gauge to the service point of the KVP and, when unit started, adjust the KVP to -15ºC (2.6bar
/ 37.7psig).
(9) Remote Ice Queen Machine Installation: Connect to the Power Supply
The ice maker must be permanently connected to the power supply. There is a terminal box where the connections must
be made; it will be accessible removing the service cover of the outlet box.
All wiring must conform to local, state and national codes.
The ice machine must be grounded in accordance with national and local electrical code.

Start-Up

(1) Previous Checkup
a) Is the machine leveled?
b) Voltage and frequency are the same as those on the nameplate?
c) Are the discharges connected and operating?
d) If air condensed: Is the air circulation and its temperature appropriate?
MAXIMUM
MINIMUM
e) Is water pressure appropriate?
MINIMUM
MAXIMUM
NOTE: In case input water pressure is higher that 6 bar (85 psi / 0.6 Mpa), install a pressure regulator.
(2) Start-Up
Once the installation instructions are followed (ventilation, site conditions, temperatures, water quality, etc.), proceed
as follows:
1) In the case of modular modules, remove the cover to access the installation kit .
2) In case of compact models, open the deposit door to access the installation kit.
3) Open the water inlet. Verify the no existence of leakages.
4) Connect the machine to the electrical network, and switch on the main switch placed on the front side..
5) For three-phase machine if sequence is not correct, red pilot will light and is necessary to change connection
sequence.
6) After 10 min. timer delay machine will start. (this delay will happen after every machine stop)
7) Verify that there are no vibrations or frictions on the elements.
8) After a few minutes, verify that the ice production has started.
9) In the case of modular models (mainly in three-phase equipments), having the cover removed, verify that the motor
is rotating in the correct direction (see arrow on steel frame).
10) Verify that after the final cycle, the frost on the aspiration pipe is at 20 mm (0.78 in) of the compressor.
