Parker Hyperchill Plus-E Manual De Uso página 25

2 Introduction
The fan, pump and compressor motors are equipped with a thermal protector that protects them
against possible overheating.
2.1 Transport
The packed unit must remain:
• Upright;
• Protected against atmospheric agents;
• Protected against impacts.
2.2 Handling
Use a fork-lift truck suitable for the weight to be lifted, avoiding any type of impact.
2.3 Inspection
• All the units are assembled, wired, charged with refrigerant and oil and tested in the factory;
• On receiving the machine check its condition: immediately notify the transport company in case of
any damage;
• Unpack the unit as close as possible to the place of installation.
2.4 Storage
• Keep the unit packed in a clean place protected from damp and bad weather.
• Do not stack the units;
• Follow the instructions given on the package.
3 Installation
Y
For correct installation, follow the instructions given in par.7.
!
The product installed must be suitably protected against fi re risk (ref. EN378-3).
!
It is recommended that all chillers be fi tted with adequate pre-fi ltration near the inlet water to
the chiller.
Y
Liquids to be chilled
The liquids to be chilled must be compatible with the materials used.
Examples of liquids used are water or mixtures of water and ethylene or propylene glycols or oil.
The liquids to be chilled must not be fl ammable.
If the liquids to be chilled contain hazardous substances (e.g. ethylene/propylene glycol), any liquid
discharged from a leakage area must be collected, because it is harmful to the environment. When
draining the hydraulic circuit, comply with the current regulations and do not disperse the contents in
the environment.
3.1 Operating space
Y
Leave a space of 1.5 m around the unit.
Leave a space of at least 2 metres above the refrigerator in models with vertical emission of conden-
sation air.
English
3.2 Versions
Axial fans (A)
Do not create cooling air recirculation situations.
Do not obstruct the ventilation grilles.
The ducting of extracted air is not recommended for versions with axial fans.
Water - cooled version (W)
If the water to the condenser is in opencircuit, install a meshfi lter on the condensation water inlet.
Please note that for special cooling water types such as demineralized, deionized or distilled it is
necessary to contact the manufacturer to verify which kind of condenser should be used since the
standard material may not be suitable.
3.3 Water circuit
3.3.1 Checks and connection
Y
Before connecting the chiller and fi lling the circuit, check that all the pipes are clean. If not,
wash them out thoroughly.
!Y
If the plumbing circuit is of the closed type, under pressure it is advisable to install a
safety valve set to: 6 bar.
Y
Always install mesh fi lters on the water inlet and outlet pipelines.
Y
If the hydraulic circuit is intercepted by automatic valves, protect the pump with an anti-ham-
mering system..
Y
If the hydraulic circuit is emptied for shut-down periods we recommend that you add lubrica-
ting fl uid to the pump's impeller to avoid the risk of blockage when it is re-started. In case the impel-
ler is blocked then you should unblock it manually.
Remove the rear cover of the pump and carefully turn the plastic fan. If the impeller is stuck then
remove the fan and turn the impeller shaft directly. After un-blocking the impeller re-assemble the fan
and cover.
Preliminary checks
1. Check that any shut-off valves in the idraulic circuit are open.
2. In the case of a closed water circuit, check that an expansion tank of suitable capacity has been
installed.
Connection
1. Connect the cooler to the inlet and outlet piping, using the special connections located on the back
of the unit.
We recommend the use of fl exible unions to reduce system rigidity.
2. Fill the water circuit using the fi tting provided on the rear of the chiller (
3. The tank is equipped with a breather valve that should be operated manually when fi lling the tank.
Also, if the hydraulic circuit has high points, install a vent valve at the highest points.
4. We recommend that taps are installed on the inlet and outlet pipes, so that the unit can be exclu-
ded for maintenance when necessary.
5. If the chiller works with an open tank, the pump must be installed on intake to the tank and on
delivery to the chiller.
!
Warning (models 022-120): the machine is equipped with an automatic protection device for
the tank.
