Page 3: Safety
This cooling unit contains fluorinated greenhouse gas covered by the Kyoto protocol. In STULZ units the refrigerant R410A is used as standard. Refrigerants are volatile, or highly volatile fluorinated hydrocarbons which are liquefied under pressure. They are incombustible and not hazardous to health when used as intended. -
Page 4: Safety And Environmental Requirements
Splashes of fluorinated hydrocarbons in the eyes can be blown out or fanned out by an assistant. Then rinse with water. Independent conversion and manufacture of replacement parts The system may only be converted or modified after consultation with STULZ. Original replacement parts and re- placement parts/accessories authorised by STULZ are an aid to safety. Unacceptable operating methods The operating safety of the system is only guaranteed when it is used as intended. -

6. Installation 6.1 Positioning Check that the installation site is appropriated for the unit weight, which you can read in the technical data. The A/C unit is designed for the inside installation on a level base. The solid base frame contributes significantly to an even weight distribution. - Page 18 Locate the fan unit in the raised floor first. The di- stance from the upper edge of the raised floor to the base should at least be 515 mm. If the raised floor is higher you can additionally use a raised floor socket to equalize the height difference.
- Page 19 Bolting of heat exchanger unit and fan unit The heat exchanger unit and fan unit may be bolted together, to prevent a move of both parts to each other (e.g. in case of a shock from the front). The screws and washers are included, drill holes are existant, appropriate cage nuts are already installed in the fan unit.

- Page 22 A/C units with speed controlled compressor (AS version) The units contain an oil separator which is installed at the hot gas side of the compressor and serves to recuperate oil in all operating states. The separated oil is injected on the suction side of the compressor. For the hot gas line and the liquid line each a non return valve is supplied loose with the A/C unit.
- Page 23 6.2.1.3 Strength pressure test The compressor has been strength-tested in the factory. It is not necessary for the customer to strength- or leak-test the compressor again. 6.2.1.4 Tightness/pressure test Use only dry nitrogen for pressure testing of the refrigerant circuit. Do not subject the compressor to dry air.

- Page 64 12.1.4 Fault elimination Important! Most operational malfunctions are not caused by faulty equipment but rather by improper installation or disregarding of planning guidelines. Therefore, a complete fault diagnosis always involves a thorough examination of the entire system. Often, the steam hose connection has not been properly executed, or the fault lies with the humidity control system.

- Page 67 12.2 Reheat The reheat is an optional extra for your A/C unit. It is installed complete and integrated in the function and method of operation of the A/C unit. It is used to heat up the air. The following versions of the heater are available: - Electrical reheat - Hot water reheat (HW) - Hotgas reheat (HG)
- Page 68 Installation The reheats are installed and connected in the A/C unit. The HW reheat is to be connected on site to the external hot water circuit. The pipelines are to be routed out of the A/C unit. The thread sizes for the connection piping of the HW reheat are listed in the following table.
- Page 69 12.3 Air side connection For the air side connection on top of the unit exist different options, which are delivered in a completely assembled condition. On the installation site these set-ups must be set upon the unit and must be connected to it. 12.3.1 Duct The duct will be set on top of the unit and be screwed with the unit.
- Page 70 12.3.2 Bag filter top The bag filter is available for all downflow units. The bag filter serves for the pre- filtration of the air which is sucked in and can be obtained in the qualities F6, F7 and F9 (according to EN779). The bag filter top will be set on top of the unit and be screwed with the unit.

- Page 87 12.5 Electrical Options 12.5.1 Three Phase Control The phase monitoring relay monitors a phase failure and a phase reversal. Excess voltage, undervoltage and the phase imbalance are monitored in relation to the set values. In case of a phase failure the phase monitoring relay is de-energized without delay and triggers an alarm. If the moni- toring relay detects a wrong phase sequence during the A/C unit start, it is not energized and prevents the unit start.
- Page 88 Adjusting the softstart controller The softstart controller can be set as a current limitation or as softstart device. The factory setting is current limitation. In this function the softstart controller allows the current to exceed the nominal operating current for an adjustable time after the compressor start.

- Page 90 12.5.4 Manual override board The manual override board is located in the E box and is used for the manual control of components in the event of a controller failure. With the help of this board, 4 digital outputs and 3 analog outputs can be operated manually. If the A/C unit is equipped with a damper, a timer in the E-box ensures the delayed start of the fans, after the damper is opened.
