Quartz TECHNICAL MANUAL AIR COOLED WATER CHILLERS AND HEAT PUMPS WITH AXIAL FANS, 06617645-02

Installation Instructions – General

-When installing or servicing the unit, you must follow the instructions given in this manual and on labels attached to the unit.

-As the chiller is charged with refrigerant under pressure and unauthorised access to the electrical components provides a shock hazard, any work performed on the unit must be by suitably trained personnel only.

-Failure to observe the instructions provided in this manual, or any modification of the unit without explicit previous authorisation, will invalidate the warranty.

Attention: before servicing the unit ensure that the electric supply is disconnected.

Inspection

After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition; any eventual damage must be reported to the carrier and be recorded on the Delivery Note before it is signed. TEV Ltd must be informed, within 8 days, of the extent of the damage. The customer should prepare a written statement of any severe damage: digital photos of any damage is useful.

Lifting and site handling

When unloading the unit, care must be taken to prevent damage to the refrigerant circuit, condensing coils or unit casing.

When using a crane, pass bars through the base frame lifting holes (marked with yellow arrows) and attach the cable or chains to these bars. Ensure that they are clamped firmly. Protect the sides of the chiller with boarding or material of a similar nature.

Forklift forks must be inserted in the base pallet: care must be taken to prevent them hitting the base or panels. Keep the unit horizontal to avoid damage to the internal components.

IMPORTANT: be sure that the method of lifting does not allow the unit to slip from chains or slings, turn over or slide from lifting devices.

Unpacking

When unpacking, be careful not to damage the unit. The packing is made up of different materials: wood, cardboard, polythene etc. We recommend that they are sent to a re-cycling centre in order to reduce their environmental impact.

LOCATION AND MINIMUM CLEARANCES

QLAC units are designed for external installation. Any overhang or cover above the unit should be avoided as this can cause air re-circulation. It is advisable to create a firm base for the unit, with a size similar to unit foot-print. Normal unit vibration levels are very low: it is good practice, however, to fit a rigid rubber interface between base and unit frame. Where desirable, fit anti-vibration mounts (spring or rubber), to keep vibration to a minimum. For future maintenance, these clearances are recommended:-
