It is needed to keep 1° inclination in drainage direction (picture below), do not mount AHU in opposite direction.
5.5.3. DRAINAGE INSTALLATION Before every heating season the condensate tube shall be filled with water as indicated during the first start-up! Before every heating season the condensate tube shall be filled with water as indicated during the first start-up! AHU (1) is built on a foundation in a such way that the side of AHU (1) with drainage exhaust pipe (2) is lower 0° - 3° than the other side (the con- crete max.
5.8. START-UP RECOMMENDATIONS 5.8.1. SYSTEM PROTECTION The control automatics of the unit have integrated protection against a short circuit of those assemblies. The controllers have the following pro- tectors: F1, F2 - 1A(5x20) MCB protection; To ensure safe maintenance of the unit, it is necessary to turn off main switch and/or external protection device. 5.8.2.
FILTERS MAINTENANCE Changing filters, filters reload timer control. Description of remote control panel functions is provided in the remote control panel technical documentation or on the website www.salda.lt. Allowed to operate the unit without filters! It is advisable to change the filters every 3 - for 4 months, or according to their testimony timer remote control.
- Make sure, that impeller’s balance weights are not moved. - Make sure the impeller is not hindered. - Mount the fan back into the unit. Connect the fan to power supply source. - If the fan does not start after maintenance or repair, contact the manufacturer. Be sure the unit is disconnected from power source before performing any maintenance or repair.
7. CONTROL Supply air temperature can be adjusted according to the temperature measured by the supply or extracted air temperature sensor and the temperature which is set by the user on the remote control panel. When the supply air temperature is lower than the set, bypass damper of the units RIS PE 1000 3.0 and RIS PE 1500 3.0 is closed and fresh outdoor air passes through a plate heat exchanger.
7.2. USING THE UNIT IN BMS NETWORK The recuperator can be connected to the BMS network by using the ModBus protocol. The device can be controlled using FLEX panel and BMS network simultaneously: the device will work based on the latest changes of settings. As set in the factory, the device will operate (if no faults are present) based on the latest panel settings in case the panel or BMS network (or even both) is disconnected.
7.5. SYSTEM ADJUSTMENT GUIDELINES Before commissioning, device launching and adjustment works must be done only by qualified and trained personnel. Automatic control system of the ventilation unit must be properly adjusted to work adequately. Also, install measuring and operating devices in line with the provided guidelines. Air temperature sensors and air quality converters.
