Remove the bottom access panel by unfastening the panel fixing
screws (2 on PHV1000, 4 on PHV1500 & 2000 units) and sliding
the access panel out forwards. Clean the inside of the access
panel.
Vacuum clean and remove any build-up of dust, dirt and debris within the air-curtain,
especially on the face of the coil and the electric heating elements.
Note: Fan motors are permanently lubricated and require no additional lubrication.
Once the air curtain has been cleaned, visually inspect the air curtain components.
Ensure pipe temperature sensors are located in their pockets and any foam insulation
covering these pockets is un-damaged. Check the location of the thermal overheat cut-
out and air sensor and that the thermal overheat cut-out switch has not tripped (see
Section – Commissioning, Page 11). Check all electrical connections and terminals
within the unit are tight and that crimp connections have not become loose.
Refit the bottom access panel and air inlet grilles with filters. Switch on the electrical
supplies and fully function test the air curtain to ensure correct operation (see Section –
Commissioning, Page 13).
Reset the Filter Dirty Indicator after the service by
pressing the Reset Button for at least 5 seconds (even if
the indicator has not gone flashing red).and hand back the
unit to the end user.
