Working Conditions; Transportation - Storage - Installation - VENCO VHR Series Installation, Operation, & Maintenance Instruction

4. WORKING CONDITIONS

The heat recovery units effectively work at the temperatures between -5°C and +40°C at the relative humidity
80%. The unit is not applicable for the corrosive conditions. For different working conditions, please contact
with VENCO.
If there is no frost protection on the unit and the outside temperature is less than -5°C, the unit must be stopped
and you should contact with VENCO. The condense water can be frozen at the temperature less than -5°C
and it can damage the exchanger.
With frost protection system, units can work at the temperature between -30°C and +40°C at the relative
humidity 80%. With the frost protection case; if the exchanger thermostat senses below -5°C, exhaust fan
jumps to highest speed, and fresh air fan drops to lowest speed. And there is a warning message "Frost
Protection" popups on the controller screen. The unit functions and the controller screen rolls back to normal
situation, when the exchanger thermostat senses above -5°C.
5. TRANSPORTATION – STORAGE – INSTALLATION
All heat recovery units by manufactured VENCO are controlled and tested according to the standards before
the transportation.
During transportation, lifting and landing, heat recovery units are damaged especially due to wrong methods
usage. Appropriate lifting methods should be used in order to minimize any possible damage. Transpallet or
forklift can be used for lifting or transporting small units. Lifting and transportation should be done with trained
and experienced personnel and security precautions should be taken to prevent the unit to fall over or slide.
During lifting and transportation of the unit, nobody should stay under the unit or in the front of the unit (Figure
5.1.).
Figure 5.1. Lifting Schema
During Storage; heat recovery units have to be kept in a closed area where the heat should be between – 20
ºC and + 40 ºC and relative humidity should not exceed 80%. Also the unit should be kept away from dust,
gas, corrosive streams and effects causing corrosion.
During Installation; EN 60204-1 rules should be implemented during the final assembly. Before the installing
of heat recovery units, customers should control whether weight and dimensions of the stations are suitable
for the places from where stations will pass through and assembly will be carried out. There should be sufficient
amount of place around the unit to be able to give service and for piping connections. Heat recovery units
should be assembled onto a hard and flat base.
Damages due to wrong transportation-storage-installation are not covered under warranty.
