Halls Autovent - Automatic Window Opener

Description

The Hall Greenhouse autovent allows your greenhouse to reach a required temperature after which the window will start to open. Any rise in temperature will now cause the window to open wider. 

Technical Information

Opening temperature range adjustable between 15C and 25C (59F and 77F). Will lift 7kg i.e. a window weighing up to 14kg (glass area not exceeding 0.75 sq. m in aluminium frame).

Can be used in conjunction with any Halls opening roof vent. When fitting to wooden greenhouses the window bracket and the gripper can be screwed directly onto the framework.

Maintenance

Lubricate all moving parts after fitting and each subsequent spring and autumn using a light oil. Use a grease or petroleum jelly for the piston rods. After long periods of low temperature and at least once a year take the weight of the window with one hand and move the adjusting screw.

Guarantee

Provided the autovent has been correctly fitted in accordance with the instructions, it carries a one year guarantee from date of purchase. Should it fail to operate during this period please return either the complete unit or defective part to the address on the instructions.

Service I received was fab

Its still sitting in my cupboard as was too hot in greenhouse to fit unless I went out 6.30 in morning, now too late to fit because of freezing in winter. However, service I received was fab. I had to ring first as wasn't sure what I was supposed to get.

Does it's job nicely.

Fitting can be awkward.Suggest you prepare by removing your existing fittings,while the unit sits in your fridge/freezer for a short while,in order to ensure that it is fully closed,before you commence.This is because a warm day can result in the unit being partly open,when trying to fit it,and, believe me, this can cause a great deal of aggravation. Once it is fully closed, fitting is relatively easy,and ours has been working perfectly all through this summer.

Does the job - but fiddly

Tried several times but due to arthritis had to get someone to attach it for me, otherwise it works fine.
