1 Introduction 1.1 Product description The product is not applicable for transportation of air that contains explosive, flammable or aggressive media. The product is not applicable for locations where there is a risk of explosion. The product is a smoke gas fan with an AC motor. 1.3 The product is not supplied with an external speed control or power switch. 1.2 This document contains instructions for installation, operation and maintenance of the product.
Note: 2 Safety The data on the name plate applies to “standard air” that is specified in the standard ISO5801. 2.1 Safety definitions Warnings, cautions and notes are used to point out specially important parts of the manual. 1.5.1 Type designation Warning Product name ZRS Dimension 170 If you do not obey these instructions, there is a risk of death or injury. 180 Motor type 1.
• Read this manual and make sure that you understand the instructions before you do work on the product. • Obey local conditions and laws. • The ventilation contractor and the operator are responsible for correct installation and intended use. • Keep this manual at the location of the product. • Do not install or operate the product if it is defective. • Do not remove or disconnect safety devices. • Make sure that you can read all warning signs and labels on the product when it is installed.
4 Installation 4.1 To do before the installation of the product 2 Cut a hole in the insulation carpet. Make sure that the hole has the same dimension as the inlet cone of the fan. 3 Install the 4 adjustable steering rods in the holes in the bottom plate of the fan. Use the supplied screws and nuts. • Use installation material with fire resistance rating for the installation location. • Examine the packaging for transportation damage and remove the packaging from the product carefully.
4 Push the fan and steering rods into the chimney. It is not necessary to attach the fan with screws in the chimney, the steering rods keeps the fan in position. 5 Electrical connection 5.1 To do before the electrical connection • Make sure that the electrical connection agrees with the product specification on the motor name plate. • Make sure that the environment for electrical connection is clean and dry.
6 Commissioning Caution • If strong vibrations occur during commissioning, immediately increase or decrease the fan speed until the vibrations are decreased. Continuous strong vibrations can cause damage to components. • Do not increase the fan speed to a higher rpm value than the maximum value that is given on the name plate. 7 Operation 7.1 To start a product with an AC motor 1 Set the installed safety switch in the ON position. 2 Install the external speed controller.
8 Maintenance Warning Set the installed safety switch in the OFF position before you do the maintenance unless the instructions tell you differently. Make sure that the safety switch is not accidentally set in the ON position. 8.1 Maintenance schedule The intervals are calculated from continuous operation of the product. Maintenance task Usual operation conditions Each 6 months Each year Unusual operation conditions.
9 Troubleshooting Note: If you cannot find a solution to your problem in this section, speak to Systemair technical support. Problem Cause Solution The fan impeller is not correctly balanced. Speak to Systemair technical support. There is dirt on the fan impeller. Clean the fan impeller carefully. Refer to 8.2 To clean the product page 7. The fan impeller has damages or deformations because the transported air contains aggressive media. Speak to Systemair technical support.
Problem Cause Solution The fan impeller does not turn in the correct direction. Make sure that the electrical connection is correctly done. A phase loss occurred. If the motor is a 3-phase motor, make sure that no phase is missing. Note: This is not applicable for EC motors. The motor is overheated. Thermal contacts, PTC or resistors are released. • Do a check of the motor cooling impeller. • If it is possible, measure the resistance to do a check of the motor winding.
10 Disposal The product follows the WEEE directive. This symbol on the product or the packaging of the product shows that this product is not domestic waste. The product must be recycled at an approved disposal location for electrical and electronic equipment. 11 Warranty For warranty claims, send a written maintenance plan and the commissioning report to Systemair. The warranty is only applicable for these conditions: • The product is correctly installed and operated. • Motor protection is used.
