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, lter 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 lter (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 lled 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 lter insert, if equi-

pped.

 It is not necessary to remove the lter insert from the

inlet grill to vacuum it. Be careful when vacuuming the

lter inset, otherwise the ltration textile could be torn.

n If it is highly fouled, remove the lter insert (remove

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

an water. Remove the damaged lter insert.

 Reinstall the bars (see gure #34) - start in the cent-

re, and ensure the textile is properly stretched.

 Install and x 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.
