Screening Checks and Maintenance

DoorMaster air curtains are made of high quality com-

ponents; therefore, they do not need special maintenan-

ce. It is only recommended to perform regular service 

checks (every six months of operation) which include 

removal (vacuuming) of dust deposits from the air cur-

tain interior, filter and heat-exchanging surfaces of the 

exchangers (blowing or vacuuming), if equipped.

Before performing maintenance, read the safety instruc-

tions on pages 3 and 12, and observe them during the 

maintenance work. Before starting any service work, 

ensure that the main switch is always turned off and 

secured to avoid accidental starting of the device during 

service work. Wait until the heat exchangers cools down 

(close inlet valves). Removing live electrical parts of the 

air curtain is forbidden. It is advisable to hire an authori-

zed contractor to perform regular maintenance.

 

Maintenance Procedure

 

Check the inlet grill, and if necessary remove the 

dirt.

 

Check the filter (if equipped) for fouling, replace if 

fouled.

 

Check the heat exchanger (if equipped), and if nece-

ssary remove the dirt.

 

Check the heat exchanger (if equipped) for leaks, 

and if necessary repair.

 

Check the outlet grill, and if necessary remove the 

dirt.

 

Check the impeller connection to the motor shaft.

 

Remove the dust deposits from the air curtain interi-

or.

 

Check all electrical connections.

 

Check the grounding.

 

Clean the air curtain external casing.

Regular Checks 

Throughout the air curtain service life, the user is ob-

liged to perform regular inspections of the electrical 

equipment at intervals in accordance with the applicable 

legal regulations.

For a list and frequency of regular inspections, measu-

ring and testing of the air curtain electrical equipment, 

refer to table 4.

Important:  If taking the exchanger out of operation 

during the winter season, the water must be com-

pletely drained from the exchanger, and possible 

water residuals must be removed, e.g. by blowing 

out the exchanger with pressurised air; or the ex-

changer must be filled with a safe antifreeze soluti-

on of water and glycol.  The water residuals can fre-

eze in the exchanger and damage the copper pipes.
External Casing Cleaning Procedure 

This applies for the inlet grill, output slit and external 

casing. 

  Safely disconnect the device from the power supply.

  Remove the dirt and dust deposits using a rag and 

detergent solution.

Filter Insert Check (type D)

This applies for the inlet grill and filter insert, if equi-

pped. 

  It is not necessary to remove the filter insert from the 

inlet grill to vacuum it. Be careful when vacuuming the 

filter inset, otherwise the filtration textile could be torn.

n If it is highly fouled, remove the filter insert (remove 

the bars, see figure #34) and vacuum or wash it in cle-

an water. Remove the damaged filter insert.

  Reinstall the bars (see figure #34) - start in the cent-

re, and ensure the textile is properly stretched.

  Install and fix the inlet grill.

Cleaning the Inlet Area

This applies for inlet grill and heat-exchanging surfaces 

of the exchanger. 

  Remove the inlet grill from the air curtain body (refer 

to page 11).

  Remove the dirt and dust deposits using a rag and 

detergent solution.

It is recommended to execute all the checks mentioned above 

before and after heating season.
